I have Family Mobile (rebranded T-Mobile Service by Walmart). It's cheaper @ $40 a month (2.5 GB of 3g/4g speed and after it slows unless U buy more). So it cost less but gives more data than the official T-Mobile. Here is the trade off tho, they cap the H+ @ around 120-170kb/s. As far as I'm concerned that's a great deal. Btw , I'm constantly on 3g/H/H+ only. Changes up if I use data.

On another note, I tested it with a T-Mobile official SIM and got LTE.

I did a Region SIM unlock and the AWS unlock to enable all bands this phone was designed to do. ATT intentionally just didn't enable all the band's, lol.

VZW Samsung Galaxy Note 3 World Phone Unlocked

Hello! Can you, please, help me out set my phone (Samsung Galaxy Note 3 by VZW) on Straight Talk network, please?

Thanks!
[AT&T Samsung Galaxy S 4 General] Joblowcheesehead:
hi I just bought a sgh-i337 I bought the byop plan from walmart and put the att sim in and the correct apn settings but when I do the speed test I only get 10mbps and lower most of the time at my work but at my house I figured I should get a lot more im right in the city limits the most I have ever got was 13 I see people posting all the time with double my speeds what am I doing wrong am I suppose to call st thanks for any advice
[AT&T Samsung Galaxy S 4 General] mattgyver:
Download Sensorly and/or OpenSignal. I prefer Sensorly, as in my region it seems to be more accurate. Both will not only do speed tests, but will show a map of coverage based on other users' results.

If your signal strength shows 4g, not 4g LTE, you'll pull at hspa+ speeds. In my area, hspa+ gets me 9-11mbps at best, which I think is probably what's happening to you. Once I get to an area with high LTE saturation, I have gotten up to 29.

Verizon S4 to Straight Talk

Hi :) I am attempting to use a Straight Talk ATT micro sim card in my Verizon Galaxy S4. I have done lots of research and keep getting conflicting info :(

I came across this thread and you seemed the most knowledgeable. Are you able to help me do this as well as provide or tell me where I find the correct APN settings to make it work?

ANY help you can provide would be great!!!

Thank you!!!
[AT&T Samsung Galaxy S 4 General] zounduser:
What problem are u having? All u need to do is put it in global mode and download the straight talk data settings app from playstore. Open the app and follow the instructions.
[AT&T Samsung Galaxy S 4 General] josephmartins:
Not so fast...

Old thread, but I felt I should add my recent experience here.

We have a Samsung Galaxy S4. It most definitely

does not work 100%

with StraightTalk.

I spent 3 days back and forth with emails and nonsense "fixes" recommended by ST support that accomplished nothing - from reboots to edited APN settings.. At no time did support tell me that ST didn't fully support the phone. It was late on the third day that one of the customer service reps told me they do not fully support WCDMA phones. That was news to me. I don't even know if it's actually true.

Here is what I can tell you....we encountered 3 major issues immediately after transferring to ST.

we lost the ability to send a text to multiple receipients simultaneously

we lost the ability to send or receive texts with any type of multimedia attachments

And the programming process altered our contact list in a way that made calling directly from the list impossible. It appended "+" to every contact number. Consequently, the phone now thinks all of the domestic numbers are international. Worse, if we attempt to dial from the contact list, we hear a message telling us that the phone is unable to make "international calls". Keep in mind there isn't an international number in the entire list.

All of the APN settings and the Network Mode are correct. I am certain that given enough time we would encounter more issues.

In any case, unless Z51 knows something everyone else does not, then the Samsung S4 is only partially functional at best using ST's BYOP SIM program. Z51, if you are still an active member and know what is required to resolve these issues, I'd really appreciate the insight.

Kind regards,

Joe
[AT&T Samsung Galaxy S 4 General] mattgyver:
Joe, what s4 variant do you have? The Verizon one?

The att and tmo variants work fine on straight talk. I've had the att variant on ST since June 2013 and it's always worked flawlessly.

[AT&T Samsung Galaxy S 4 General] josephmartins:
Hi 0p3nsrc,

It was purchased from Verizon when my wife renewed her plan. It's *supposed* to be an unlocked GSM/WCDMA phone. Does anyone know specifically what firmware/HW/SW differentiates a "Verizon variant" from others? I can understand rebranding a product, but I cannot imagine a circumstance under which the actual HW/SW would/should vary to the extent that it breaks portability.

If anyone has identified the differences, I'm hoping it's something I can remove/modify to bring it into alignment with the variants that actually work.

Incredibly silly that Verizon would be permitted to qualify its variant as an "unlocked" phone if, in fact, it is deliberately modified in any way to prevent advanced functionality from working on competitors' networks.

Kind regards,

Joe
[AT&T Samsung Galaxy S 4 General] Z51:
to be honest, the straight talk reps are full of sh*t

they suck and its always an indian or filipino who answers. never someone with any knowledge

what APN settings are you using?

why arent you able to send MMS?

fix your APN settings/.
[AT&T Samsung Galaxy S 4 General] mattgyver:
Joe, not much is different HW wise. It's mostly software. But the vzw s4 is unlocked to non US GSM carriers, iirc.

There's never a lack of reading on XDA! Hopefully that thread helps.

Yeah, the US variants only have minor differences. The international version is the one with the most hardware differences, as is usually the case with international versions of most phones.

Sent from my TARDIS
[AT&T Samsung Galaxy S 4 General] josephmartins:
I learned that very quickly Z51. My very first call to support to perform the transfer of two phones was one of my most painful customer service experiences. After an hour I told the guy I'd call back and speak to someone else. I ended up emailing them instead. It turned out that their email support was better than their phone support -- probably perception since I couldn't hear the strained American accents from individuals who most definitely are not named Linda and Angel.

Straight up MMS works fine at the moment. My wife can send and receive ordinary texts to individual recipients. She cannot, however, send or receive multimedia attachments via texts which is something she did frequently via Verizon just days before. Now the spinning activity icon just spins indefinitely and the texts with attachments never send or download. Same goes for texts to multiple recipients. If she crafts a text and selects more than on recipient, the text is never sent.

Lastly, the programming process from StraightTalk modified her contacts. I have no idea why it would touch the contact list and append "+" prefixes the way it did. The country code is correctly displayed as the US, but any attempt to initiate a call from the contact list fails with a message about not being able to make international calls.....these are all domestic telephone numbers. Worse, I cannot seem to find a way to alter settings to correct the issue.

APN is currently set as:

APN: tfdata

Port: 80

MMSC: http COLON //mms-tf DOT net <-- I have to write this goofiness until I'm allowed to include links on this forum

MMS proxy: mms3 DOT tracfone DOT com

Message Port: 80

Everything else set to defaults or not set at all, e.g.

MCC: 310

MNC: 410

etc....

From what I could tell in my research these settings are fairly standard. Do you use something different?
[AT&T Samsung Galaxy S 4 General] mattgyver:
Ready for more fun.. Did you buy the att straight talk SIM, or the T-Mobile straight talk SIM. They work on different cellular spectrum, so the T-Mobile SIM needs T-Mobile APN settings..

The APN settings you have are att SIM specific.

Your terminology is a little off. Your wife can use SMS, but not MMS. SMS is plain Jane texting. MMS is the multimedia messaging service - sending pictures, videos, etc.

If she can text, but not MMS, that definitely sounds APN related. Can she did the web via mobile data? What messaging app are you/she using? As silly as it sounds, it may make a difference.

Sent from my TARDIS
[AT&T Samsung Galaxy S 4 General] josephmartins:
I'm pretty sure it's an ATT SIM:

TF64PSIMC4BMB (though I have read some users got better results -- i.e. higher speeds -- from the 4MB version, but who knows what other factors affected their results)

Last 5 digits: 10425

Sorry I lazily use MMS as if it's interchangeable and I shouldn't

So she can SMS (individual recipients only) but not MMS. She can access web via mobile data.

She uses the default messaging app that ships with the S4...not sure of the name. From the home screen it's just called "messaging"
[AT&T Samsung Galaxy S 4 General] mattgyver:
It's going to sound silly (and believe me, no matter how many times I do this for friends who port to ST, it makes no sense) download Handcent SMS from the play store.

Go into handcent. Go to settings > application settings > MMS settings. Select manual mode for carrier. Put the mmsc, port, etc in. Save and close.

Send an MMS. Report back if it works..

Maybe this isnt a great question to ask, but is there anyway we can maybe extend our throttle limit by a tad? 3.0GB is kinda low when ur downloading touchwiz roms.

Buy a 4gb at&t plan?

I mean, for a while, we were lucky to get 2.5gb per 30-day cycle. Now we get 3. That's more than the base att plans. Straight talk sets the throttling. I don't think you can get around it with just apns. I could be wrong, but I've never heard of anyone being able to get too much past their throttle.

Hi everyone,

I just bought a Tmobile Galaxy S4 and sim unlocked it. I'm trying to activate it on Straight Talk, and purchased one of the original ATT sims. I read that someone was getting 4g speeds on an ATT Sim using this same setup on an S3. Here's my thoughts and problem....

1.) I can't get or seem to find the correct APN settings. Googled and youtubed several, nothing seemed to work. Tried restarting after each attempt to no avail. Also tried the above and still no internet

2.) I'm starting to wonder....even though it's sim unlocked can I use the ATT sim and it's just a matter of getting the right APN settings?

Right now I can make calls, send / receive texts, but can't get the internet to work let alone try and get the best speeds

Any thoughts? Help appreciated!!:good::good:

Six of one, half a dozen of the other... Depends on your region. I'm in central Pennsylvania, all the major carriers are present, and coverage is mainly even. Both have dead spots, though. Usually where one has a dead spot, the other gets coverage.
