The Sprint S7 variant does support band 4 (not sure why you think it's missing), and because it supports band 12, then by definition it also supports band 17 (thanks to MFBI being deployed on AT&T's network).

---------- Post added at 07:55 AM ---------- Previous post was at 07:11 AM ----------

Assuming these phones are unlocked and you are trying to operate them on a true GSM carrier then make sure you have the correct APN settings in the phone. Also, install the app 'Network' from the App Store then set the preferred network type to LTE/GSM. Afterwards you may need to restart a couple times. See if that helps.
[Sprint Samsung Galaxy S7 Questions & Answers] asadnow2k:
I can unlock your phones for free :)
[Sprint Samsung Galaxy S7 Questions & Answers] asuh:
Please review Samsung's own website for the Sprint variant:

http://www.samsung.com/us/support/owners/product/SM-G930PZDASPR

You can also read the posts above where I copied and pasted the different bands supported by both Sprint and AT&T listed on the above link. Sprint locks down the device to have different LTE bands than AT&T. Without an unlocked bootloader, there is no way to flash to AT&T's LTE bands.

Samsung has not released the unlocked bootloader. The only thing truly unlocked is the LTE bands for the various US carriers. So I don't know how you can flash over to the other carrier software?

thanks for the replay, I solved that issued by entering service manu and activating wcdma/gsm in SETTING->protocol->GCF.

settings

activate this phone

vol- vol- vol+

vol+ vol+ vol- [shows the service mode]

testmode->settinginfo->setting->protocol->gcf->gsm(e)gprs/wcdma gcf on

restart phone

Now the cell gets signal back on its own.
[Sprint Samsung Galaxy S7 Questions & Answers] myphone12345:
I am not sure why you keep insisting that the Sprint variant (SM-G930P) doesn't support band 4. It certainly does, I have personally used band 4 with an unlocked Sprint S7 on T-Mobile. Also, the Official Samsung Specs for the SM-G930P also show band 4 as available and it also shows up in the list of bands in the LTE band prioritization listing on the phone itself (look at the attachment to post #15 in this thread). You do not need to flash the device to make this happen, you need to either sim unlock it or roam on a Sprint partner which uses band 4 (through the Sprint CCA and RRPP programs, see here: http://www.fiercewireless.com/story...ners-have-now-launched-lte-service/2015-05-20 ).

In other words, the Sprint variant (if SIM unlocked) is fine for use on AT&T as it supports all of AT&T's major LTE bands (2, 4, 12 [17], and 5).

Thanks for the information. Did you need to have the MSL code to make this change?
[Sprint Samsung Galaxy S7 Questions & Answers] asuh:
My bad, you're 100% correct. Got mentally stuck on another post in this thread which said only 2 and 12 even after I knew better. My apologies.

No data connection?

Hi, a couple of days ago, I bought the unlocked sprint gs 7 and tried to use it for ATT. The guy working at ATT couldn't get the phone to receive data connection (4G) even after asking other professionals. Is there any way to solve this problem? :)
[Sprint Samsung Galaxy S7 Questions & Answers] bLueBry:
hey yall,

super new to androids, been an iOS user for the past 5 years.

But i recently got a s7 930P (sprint) , I'm trying to use the phone with ATT

I purchased the cable unlock software from unlockbase.com, who claimed that they supported unlocking the g930p.

It didnt work and still says invalid sim. Does anyone know if its true that their software is for international and wouldnt unlock a domestic phone here in the US?

I found a guy on Craigslist that works at cricket and said that he can unlock it for me for 35 bucks.

Does anyone know anything about this? and if its a good idea, i understand cricket is on the att network. Hes the manager, so he claims he can get it done in less than 10 minutes. will i have any problems? and is this a safe bet?

thanks so much,

bluebry
[Sprint Samsung Galaxy S7 Questions & Answers] bLueBry:
i was about to ask about gsmzambia. , but i already paid for a cable unlock software that didnt work. that is why im reluctant to do it again. They are refunding me though.

But im willing to pay the 35 to guarantee i can use it on ATT.

GSMzambia is legit?? how sure are you that it will work on this ****ty g930p

---------- Post added at 01:58 PM ---------- Previous post was at 01:53 PM ----------

also sir,

does gsmzambia network unlock it? , or do i need a sim unlock, or both? i'm a bit confused on the differences, have only been researching for a couple hours and i have to get to class, so i can continue this Homework till later.
[Sprint Samsung Galaxy S7 Questions & Answers] bLueBry:

[Sprint Samsung Galaxy S7 Questions & Answers] TehPirate_:
Depends on the bands available where you live. I get LTE on Cricket on my Sprint variant most of the time. The only band I'm missing is band 21 which is the best for LTE here.

another dumb question, a phone blacklisted for sprint, once unlocked will be fine for all other carriers correct?
[Sprint Samsung Galaxy S7 Questions & Answers] .dan:
A blacklisted phone in the US should not work with any carriers in the US. This prevents people from stealing phones and using on another us network.

super new guys but i need help.

i just unlocked a sprint s7 g930p

I added ATTs APN settings,

is that the best way to get the best coverage?

can i do anything else to get better reception,
[Sprint Samsung Galaxy S7 Questions & Answers] .dan:
possibly, if you are able to get the MSL code (associated with your IMEI), you can modify your LTE priority through the secret phone menu. i was not able to get my MSL from sprint as i am not a client.
[Sprint Samsung Galaxy S7 Questions & Answers] johnathonnehls:
Hi,

I just had a remote sim unlock done on my sprint galaxy s7 and ported my account to ATT Wireless. I do have working calling texts and 3G data. But do not have LTE... I manually added the APN to get 3G. Am I missing something here or will this phone not pickup the LTE from ATT? If I am in the wrong place could someone direct me to where I can get this answer? Thank you in advanced.

---------- Post added at 04:02 PM ---------- Previous post was at 03:58 PM ----------

Hi,

I used The Android Doctor. just do a quick google search and it will pop up. You will need a Samsung USB cable, and a Windows PC. You pay $15 and they will email you instructions. Install the downloads they provided you by email and sign in to the remote software. One of the techs actually remote in to your computer and provides you instructions to get your device ready. They have you do just a few things but are pretty basic things. The process took around 15 minutes after downloading and it is a permanent unlock. Once completed they close out of the remote software and you are done. I just had mine performed yesterday.
[Sprint Samsung Galaxy S7 Questions & Answers] bLueBry:
thanks sir, i got it unlocked yesterday with gsmzambia
[Sprint Samsung Galaxy S7 Questions & Answers] johnathonnehls:
Can you tell me if you got your phone working on ATT with LTE? If so did you just add the APN and that was it?

[Sprint Samsung Galaxy S7 Questions & Answers] Swarlos87:
I called sprint to get my MSL code, but they couldn't get it b/c my phone is active on the AT&T network...so they told me to call AT&T. I chatted with an AT&T rep and got nowhere. She suggested I contact Samsung.

I'm hoping that if I get the MSL code then I can change the band priority that I'll be able to get LTE.

Anyone with any success getting LTE on an unlocked sprint 930P? Inquiring minds want to know :confused:

So flashing that ROM, sim unlocked your sprint Galaxy s7?
[Sprint Samsung Galaxy S7 Questions & Answers] TehPirate_:
My device was network unlocked the day I received it. The reason I'm convinced that this would result in a sim unlock is due to the fact it's an unlocked firmware. The intention of the unlocked firmware is so the phone can be used on any carrier in the US (straight from Samsung). Also, in the ServiceMode menu, there's no references to any network lock.
[Sprint Samsung Galaxy S7 Questions & Answers] .dan:
you simply flashed the carrier-free rom using samsung tools? does this require root? if this is possible, then have you tried flashing ATT or tmobile rom onto the g930p?
[Sprint Samsung Galaxy S7 Questions & Answers] TehPirate_:
No, you flash it with Odin. no root required to flash it because it's signed by Samsung. We can flash any US S7 firmware (based on a report from another member) on any US variant through Odin.

The member I speak of reported he flashed Verizon firmware to a Sprint variant
[Sprint Samsung Galaxy S7 Questions & Answers] diego97yey:

For me, it was a Profile update. But I believe there's now an option of "UICC Unlock". Let me know if this helps
[Sprint Samsung Galaxy S7 Questions & Answers] SDRebel:
Thanks, I already tried those two but they fail (says hands free activation->waiting for retry-> tries a few times and then it fails). my guess is that the unlock hasn't gone fully through the system... dunno

I also tried the "enable OEM unlock" in the developer option. THat was disabled, but didnt' help either.

I'm thinking I can either take the software update it's been bugging me about or do a factory reset...but not sure if either will help :(
[Sprint Samsung Galaxy S7 Questions & Answers] TehPirate_:
Sadly neither an update nor reset will help you in this case. You may have to contact the reseller or Sprint

Thanks, yeah, i think i'm going to have to bug them again, though they may have to send the request to Sprint, so maybe talking directly to sprint is not such a bad idea. From what they can tell, they did their part :confused:
