the FCC says the GT-P1000 models support 850 3G

The FCC docs actually say that the GT-P1000L, N, T models do support 850GSM and 850WCDMA(3G):

Type the device's FCC ID info in, (A3L is the manufacturer code for Samsung). Look at the documents in the 824.20 (GSM "850") and 826.40 (WCDMA "850") lower frequency ranges.

The actual test report docs list GT-P1000L and GT-P1000N and a clarification doc from Samsung says the GT-P1000T model is just a renamed L one.
[Galaxy Tab General] Suleeto:
This is great, it's exactly why I wanted to start this thread. SO, one person at least has a Euro-spec (GT-P1000) machine wortking with voice and 3G data on a US AT&T network.

Someone needs to post specs on the GT-P1000. Because right now, it would seem that the P1000 is the best bet for those who want to use FULL functionality on a US AT&T network.

My personal motivation for this thread is to get solid information on what model Galaxy Tab will have full US AT&T functionality (voice and good 3G data connect), and HOW to achieve that (choosing the right Galaxy Tab and flashing the right ROM). Once this is nailed down, I'll buy one. I just need to know which to buy and what to do to it.
[Galaxy Tab General] Raspster:
Not FULLY working on at&t's 3g network. The 850 band for 3g is still missing and 850 is their primary 3g band and it's slowly replacing the 1900 3g band. The reason they changed was because the 850 3g band can cut thru walls better and give you a better 3g signal. I remember when my area had only 1900. My 3g sucked. Very spotty unless I was outside. I instantly noticed when the 850 upgrade took place. Solid 3g even in the darkest areas of my basement @ work. There will be an unlocked 850/1900 3g band version on the tab but it looks like it was pushed off until early 2011. Probably because they knew they would never sell any of the current north american models with the 850/1900 3g bands (bell, rogers & at&t) For what it's worth, you can pre-order that version here:

[Galaxy Tab General] clubtech:
Who said at&t's primary 3G is 850Mhz?

That is just false information.

Their primary is actually 1900Mhz and they are beefing it up with new 850Mhz towers, not instead of current 1900Mhz existing in infrastructure.

Places who only recently got 3G service might be on 850Mhz but all those who got 3G up until 2 years ago are all 1900Mhz with the addition of 850Mhz.
[Galaxy Tab General] Raspster:
I need to find the artical that says they are slowly changing over the entire 3g network to the 850 band. Stay tuned.

UPDATED: Read on

http://www.intomobile.com/2009/02/24/att-3g-network-going-850mhz-nationwide-by-2010/
[Galaxy Tab General] clubtech:
Yea this article and all the others stating the same are copying the same wrong source.

At&t never said they will be replacing 1900mhz with 850mhz...they said they will be ADDING towers and expending their network on 850mhz.

Here in the sf bay area the netwrok is mainly 1900mhz but they are ADDING new 850mhz towers so now we get mixed frequencies in places where signal was bad. They are certainly not removing 1900mhz towers.
[Galaxy Tab General] siehead:
This thread encapsulates my concerns exactly. I want to use my tab as a phone, and am on ATT, so will wait to see how to best implement this agenda before purchasing anything. I have a couple of concerns:

1) I think that the Galaxy Tab forum should be split amongst various carriers, since future roms and such will likely be device specific.

2) Now that more information is coming out with regards to the Nexus s and Galaxy 2, I am wondering whether I should hold out. I do want a large screen, but the development community/google support for the next Nexus phone is hard to pass up... maybe I will buy both!
[Galaxy Tab General] Croak:
Regarding splitting up the forums, I don't think that's a good idea. We tried it for the Galaxy S models and it is something of a clusterfuck, and not as much knowledge is being shared IMHO.
[Galaxy Tab General] Raspster:
Hope you would be right as that would be the thing stopping me from getting the unlocked one. My buddy is a store manager of an at&t store and he has confirmed this with me also. Maybe some areas have not made the switch like the sf area... dont know for sure. One thing for certain, you will not get the same 3g signal (unless your outside) like you would with a device with the 850 3g band.
[Galaxy Tab General] CyberGhos:
The ATT Galaxy Tab doesn't support 850 MHZ.

http://www.att.com/shop/wireless/devices/galaxy-tab.jsp#fbid=tDxf7jg1pvy
[Galaxy Tab General] Raspster:
No way, that's GOT to be a typo!

UPDATE: Again, a typo.

http://www.samsung.com/us/mobile/galaxy-tab/SGH-I987ZKAATT-features

The 850 is listed under UMTS on Samsung's site.
[Galaxy Tab General] Suleeto:
And we still aren't sure if the Samsung listed specs are for unbranded or not... what we need SOLID evidence of is if the Galaxy Tab has ALL GSM/3g frequencies and just different ROM/firmware, or if there are indeed different HARDWARE versions per carrier.
[Galaxy Tab General] Croak:
It's pretty ****ing simple. Go look up the FCC filing for the SGH-I987, click on the Test Report link

https://fjallfoss.fcc.gov/oetcf/eas...me=N&application_id=517128&fcc_id='A3LSGHI987'

Also keep in mind the FCC filings won't list any info on non-US bands, because they don't give a damn about them, AT&T is only licensed to use the 850 and 1900 spectrums in the US, and that's all that is tested.
[Galaxy Tab General] CyberGhos:
I see squat at FCC site, but could it be the 850 MHz for EDGE/GPRS in the test report?
[Galaxy Tab General] spirit32:
att galaxy tab is on sale now! they advertised the battery as Up to 13 hours of usage on a single battery charge!!
[Galaxy Tab General] Croak:
edge/gprs/wcdma.
[Galaxy Tab General] Raspster:
I'm getting it in a bit. I'll report back on the facts.
[Galaxy Tab General] BoostedSR20:
Will At&t sell it without a plan? Or do you have to wait for the wifi only version to come out?
[Galaxy Tab General] maxtcee:
anybody get this yet and flash euro rom see if we can get calls and 3g
[Galaxy Tab General] Raspster:
Can't even send mms messages on att tab! What a shame... it won't even let u set up the wap settings in the apn settings.
[Galaxy Tab General] clubtech:
And that is after you flashed the euro firmware?
[Galaxy Tab General] ConceptVBS:
Yes, sell without a plan. Its just like the iPads.
[Galaxy Tab General] Raspster:
No, this is out of the box. Pretty lame on AT&T's part but not understandable as we all know they have been in bed with Apple for years now and care very little about anything other than Apple.
[Galaxy Tab General] maxtcee:
did you flash it yet
[Galaxy Tab General] d00mz:
Specs from the box

Here's the specs from the box. Just picked mine up

Questions??
[Galaxy Tab General] Raspster:
No, I have not. I have not even ventured down this road yet with the tab as I know it's still pretty new and not yet tested on the at&t version.
[Galaxy Tab General] BoostedSR20:
Here is a dumb one... Is the back white? Black? I played with one at Best Buy, sprint version, it was white. I'm just sitting here thinking of getting it, my local AT&T has 2...
[Galaxy Tab General] d00mz:
the back is black, as is the front. It's very sleek looking. There is a very small checkerboard pattern on the back to enhance grip on the device.

I apologize for the blur, but it's very difficult to photograph, but you can see the size of the checkerboard pattern.
[Galaxy Tab General] Raspster:
And of coarse, no mms right? I had it in my hand... Messed with the setting on the floor model for 30 minutes to see if I can get mms to show. Asked a employee in the at&t store and of coarse, deer in headlights... I was going to buy the at&t tab as I had it in my hands but after that disappointment, I handed it back. I'll wait till someone can get a MMS hack or when someone puts the euro rom and can confirm voice and 3g are working properly. I know it seems silly to NOT pick it up without the mms but I send & receive TONS of mms's and this was a deal breaker. So strange how at&t would leave this out. Was even trying to enter the APN settings for at&t by adding a NEW APN as the one in already was NOT able to be edited. As soon as you go to the 2nd line to enter wap.cingular it will stop you the minute you enter the "r" in cingular and say "can't enter this" You can enter anything you want in this field BUT the correct setting to get MMS so you know at&t did this on purpose.
[Galaxy Tab General] BoostedSR20:
Sounds like the back of the Captivate..
[Galaxy Tab General] clubtech:
Going to flash this to the euro firmware in a moment

I'll report back.
[Galaxy Tab General] Raspster:
Ok, cool. Let us know. I guess you need to enter the "*#2263#" to get in and change to 850 WCDMA for 3g and voice to work? Let us know if that works also with the at&t version.
[Galaxy Tab General] clubtech:
I just flashed straight to XXJK5 with NO repartition.

Put in my SIM from another android phone that i have with unlimited data plan.

Phone works. i can make and receive calls.

Data works after i flashed i could edit the APN to wap.cingular and data started to work.

What is think does NOT work is the 850Mhz.

Going to try and flash the original at&t radio to see if that fixes it.
[Galaxy Tab General] Raspster:
Try the *#2263# in the dialer and change to 850 band only instead of default. That is what others did to get the 3g to work.
[Galaxy Tab General] clubtech:
That did not work.

I did however fixed the 850Mhz by flashing the at&t modem only (no repartition).

Now i get 850Mhz.

Please note that you can not select only 850Mhz from *#2263# as it says "menu not found" because i don't think the euro firmware supports it.

If i select 1900Mhz only, i only get 1900Mhz.

If i select all WCDMA bands, i get 850Mhz and 1900Mhz working just fine.

Another small side effect from flashing the euro firmware: i do not see the Samsung boot logo anymore and when the device finishes booting i need to press power on to see the screen.

Other than that, i can not find anything else that is not working.

EDIT: to get rid of the above bugs:

Flash with repartition and the P1_hidden file to P1000XWJJ4

Then flash to XXJK5 without repartition

Then flash the at&t modem without repartition.

You should then have a fully working voice+data+850Mhz Tab :D

I am positing the modem.bin for at&t i am using for 850Mhz.
[Galaxy Tab General] quattr0:
Thank you for your awesome post on the xp. Just to be sure. YOu will need

1. Flash it with Euro firmware

2. Flash the modem.bin above

3. Select WCDMA bands

And you will get both voice and data @ 3G speed? You use Odin for 1 & 2 above? Sorry as I'm noob and just want to confirm. I just need to backup the /efs folder or I must backup everything using Titanium backup in case things go wrong?

Thanks again.
[Galaxy Tab General] Raspster:
Nice find clubtech... If you don't mind me asking, where did you get the P1000XXJK5 file from? Also, you just rooted, used odin and just flashed the P1000XXJK5 without setting any other settings? Forgive me for asking but I am slightly noob to samsung flashing.. Been doing HTC flashing. Also, didn't you need to press the power button to turn the screen on before?
[Galaxy Tab General] dboppc130:
how do you flash only the modem.bin?
[Galaxy Tab General] quattr0:
And another thing..who knows if AT&T won't start blocking users' sim cards so we can't use it for the tab like Tmob does? Or, am I completely wrong here. Thought I've seen a few users can't get on the net and got forwarded to Tmob web site when the same process was done on the Tmob tab....
[Galaxy Tab General] Tsaxmafia:
Ive got a buffalo nickel for the person that hooks up the tab with 3G and voice calls.
[Galaxy Tab General] mr. haison:
Even though I currently have the Verizon version of the Tab, I wanted to pick up the AT&T version because that is the carrier I am under. I was very close to buying it, but the rep swore up and down that I could not switch sim card because the network would see that I switched to a tablet and charge me extra. I wanted to use it as a secondary device since I am a heavy user on my Captivate and that usually last about 6 hours. Is there any truth behind what she is saying?
[Galaxy Tab General] Tsaxmafia:
They new when I switched to a go phone and charged me for switching my data plan, I switched for two days. They know some stuff
[Galaxy Tab General] mr. haison:
My captivate is under a a plan with 2GB data and unlimited messaging. I repeated this to the rep three times and she said I will still get charged extra if I were to switch sim card. I just don't understand the difference of a data plan sim and the sim that is in my phone and getting charged extra for something I already have.
[Galaxy Tab General] Raspster:
Can't wait till the OEM unlocked NAM version with 850/1900 bands comes out. Hopfully it will come as "UNKNOWN DEVICE" on the at&t side and allow us to have our cake & eat it. Think I may wait till then. Almost picked up the Verizon one too as my primary carrier is at&t. Don't know, still may.. Don't ya just LOVE how the US is not allowing us to have the total solution?! That would be bad business on their part... I'M MOVING TO EUROPE! :)
[Galaxy Tab General] clubtech:
I posted an how-to flash to the euro firmware to make calls here:

http://xdaforums.com/showthread.php?p=9343288#post9343288

If you put in a SIM that has a proper calling plan and a proper data plan, i seriously don't see how they can charge your extra.

you do need to make sure you change the APN from "broadband" to "wap.cingular" after you flash.

once that is change there is no way for them to charge you extra on anything (providing you have the correct data plan and voice plan)
[Galaxy Tab General] maxtcee:
so are you getting 3g and calls on att
[Galaxy Tab General] quattr0:
Perfect! Thanks again.
[Galaxy Tab General] rotohammer:
Just left AT&T with a new Tab ;)

Sent by Roto's Tab
[Galaxy Tab General] maxtcee:
i think im with you roto im returning this back to tmobile
[Galaxy Tab General] xexes:
So roto... are you giving up on the Tmo Tab?

Say it ain't so!!

I'm not particularly in love with Tmo... it's just that where I live, AT&T coverage is absolutely abymal.... they just upgraded to 3G week before last (!)... BUT the coverage is so spotty it is almost unuseable.

So am wondering if you're going to scavenge necessary code from AT&T to apply to Tmo ? Or is that even possible?

Thanks...
[Galaxy Tab General] maxtcee:
good **** club are you able to get mms going
[Galaxy Tab General] rotohammer:
I'm going to work on both Tmobile and At&t Tabs, I have reason to continue with trying to get 3g on the Tmo Tab. The At&t Tab will be better for me when I'm in Europe.

Please dont give up on the Tmo tab!!

[Galaxy Tab General] mr. haison:
I have a sim card with just the 2GB data plan that i got with the Tab. If I want to use that I set APN to broadband and if I use my cell phone sim card, I swith the APN to wap.cingular correct?
[Galaxy Tab General] TurckBoatTruck:
Since it looks as though the AT&T Galaxy Tab will be the first to truly offer 3G internet and standard voice calling... does anyone have any suggestions as to the best way to go about signing up with AT&T for those of us who will be new customers?

i.e., What plan should we get that assures us access to a voice plan, the most internet connectivity with the least monthly cost? And since they are selling the device as a 1-time purchase, will there be any gotchas when we do sign up?
[Galaxy Tab General] clubtech:
Yes if your phone sim has a proper PDA data plan.
[Galaxy Tab General] moviecouple:
Also got the AT&T Galaxy Tab but haven't had a chance to mess around with it.

Will someone post the exact step by step directions for us newbies to get the phone and 3G working on it???
[Galaxy Tab General] morrichad:
I too bought ATT version yesterday and was like use to froyo with evo and had moto droid prior, then I realized I made somewhat of a big fat mistake. Not realizing I was getting this version after buying that I was hoping that ATT wasn't pulling the crap of not allowing unknown sources, like they did on other android devices. I have searched up and down to find a solution how to enable third party sources. I know on other ATT samsung captivate you disable settings.db file changing from one number to another.

I was hoping since this thread would become like FAQ thread if someone could help me in the right direction so that I can disable ATT restrictions of outside of the market apps. I just can't believe first ATT charges more for this device then anyone else and then pulls crap like this to non-commitment no contract device. If Roto or clubtech, or someone could help me with this problem and have solution I am all ears. Thanks!!!:confused:
[Galaxy Tab General] quattr0:
Go back 3 posts above this one. Read that carefully and read this http://xdaforums.com/showpost.php?p=9346192&postcount=35

There is also a youtube video how to flash. Check out samfirmware.com They have manual and video.

You might render your tab useless if you don't know what you're doing. USE IT AT YOUR OWN RISK.
[Galaxy Tab General] rotohammer:
If all you want is to side load, you can probably follow that settings.db guide after you root. I used the rage method to root mine in order to back up the stock firmware. z4root is in the market now, so thats a heck of a lot easier than the rage method. You'll have root in 10 seconds. Then edit the db and you're done.
[Galaxy Tab General] BoostedSR20:
Just got home with my tab. I dont really have an interest in using it as a phone, so I'm not going to flash it. I am going to attempt to root/enable side loading. I'll report back...
[Galaxy Tab General] morrichad:
Yeah roto already rooted using z4root, see my problem I am not very good with push and pull of system files with adb bridge. Was wandering if I could use root explorer along with terminal emulator to perform the system file changes in settings.db file. I have basic knowledge of how to flash and install roms on the evo cause some people had really good step by step instructions from a first timer's point of view. See I read on here some of threads on how to make changes to the Galaxy Tab, but not really step by step for noobies.

Just like clubtech posted file changes to make the Galaxy Tab work with voice and data on ATT, reading the files to put on there seems somewhat difficult but I am sure with enough practice and alot of help I could do it. I mean no disrespect to you roto or clubtech or anyone creating awesome mods for this device, but for me the samsung galaxy is whole different class for me. I am willing to learn how to do these mods, but would be nice if we could get met with the proper how to guide from a noobie point of view?

Would be willing to contribute to a;) how to guide on any of these mods if someone would guide me on how to via pm or other communication means. If need be I would willing to put some necessary funds to get assistance for some time one on one with Roto, clubtech, or anyone that can help me out. Problem is I only got one shot and doing anykind of flashing since right now there is rom/recovery method yet that I am aware up for backups!!! Again Thanks;)
[Galaxy Tab General] BoostedSR20:
This is the method I'm going to use to enable sideloading:

I did this with my Captivate way back before there were any tools or roms to flash.
[Galaxy Tab General] rotohammer:
My advice is to spend some time reading the forums, any question you may have has been asked and answered at least 5 times already. Unless you plan on this being the last Android device you'll ever own, you need to get comfortable with the basics of flashing firmware and transferring files, running adb commands.

Many noobies have succeeded in modifying their Tabs. Shortcuts lead to failure.
[Galaxy Tab General] morrichad:
Appreciate the help roto its just not I am beginner noob more like I just can follow directions most times when it is explained in a way I can understand. No want be last android device at all, but just having alot of spare time for reading comes up a little short for now. May be holiday break will give a little time to read, problem is there is whole lot of info to consume. One more thing roto let me ask this if I can the methods that clubtech speaks of flashing the 2 flash files due they overwrite ATT restriction crap of outside apps and make it where you can check the unkown sources box from within the application settings box. Again Thanks
[Galaxy Tab General] rotohammer:
Yes, the restriction is not present in the European firmware. But, before you go that route, try enabling the outside app installation as thats a good beginner exercise that has a low probability of failure.
[Galaxy Tab General] BoostedSR20:
So far I'm rooted and installed OCLF. My quad score stock was 905, my score now is 2085. Using ADW launcher, this thing is very snappy. I'm happy with it.

I decided not to worry with side loading because all I wanted to do was put apps on it with Titanium Backup. (from my phone) Instead just started from scratch.
[Galaxy Tab General] KarlMarsh:
Side Loading App

Its really a shame that ATT still has to cripple all of its Android devices. I guess all the US carriers are guilty of the same thing in a way.

There are several easy ways to side load APK's without rooting or changing your settings.db file. The easiest if you have a windows machine is probably using the Android Central App. I cant post links but just google "Android Central Sideload Wonder Machine"
[Galaxy Tab General] Suleeto:
We're close. What I want to put in the reserved FAQ post and the other reserved post is everything you need to know to get a Galaxy Tab working with voice and 3G data. We now know how to get the AT&T branded model to work, but the AT&T branded one is expen$ive. I want to see that a few unbranded (OEM) Galaxy Tabs get on AT&T with full functionality, then I'll be updating the first few posts with all the information clean and simple.

I'm not going to include other things like sideload because as far as I know, those are not specific to AT&T, and are covered elsewhere. I will probably just include links to essential procedures such as sideload.

But for now, this thread is full of WIN! Progress has definitely been made.
[Galaxy Tab General] KarlMarsh:
Can someone please tell me if the ATT Tab can do Standalone GPS?

IE can it get a GPS lock with the GSM radio off or in a area with no cell coverage after a reboot?

I plan to tether it to my EVO and use NDrive which will reside on my SD card.

Thanks in advance!
[Galaxy Tab General] moviecouple:
I got the AT&T version of the Galaxy Tab... and I put in my Samsung Galaxy Captivate SIM card that does have the 2GB data plan. For some reason it doesn't even recognize the SIM card. Shouldn't it work right out of the gate? It finds the SIM card that came with the unit... and my SIM card works in my Captivate and the unlocked T-Mobile version perfectly.

Any ideas?
[Galaxy Tab General] quattr0:
dude, think about what you asked. If it works out of teh box (swapping SIM from AT&T phone to Tab), we wouldn't have this flash thingy, would we?
[Galaxy Tab General] BoostedSR20:
Yeah it works just fine. I was playing with google maps with the sim card out.
[Galaxy Tab General] moviecouple:
No, No.

What I was saying was that I have an AT&T Tab... and I have an AT&T Captivate with a SIM card that has Voice and Data already active. If I pop that SIM card into the AT&T Tab it should work. I should be able to get data, right? It is all from AT&T... device and SIM. But, for some reason it is not recognizing the card.

I though the flashing that is going on was to get 3G and Phone capabilties. I just want 3G.
[Galaxy Tab General] Suleeto:
No, you need to read this thread closer, the AT&T ROM included with the AT&T Galaxy Tab is very disabled in many ways, reflashing it should resolve that.
