Hello all, i have a question regarding an Australian Telstra Galaxy S5 with att service. the phone works with voice and text but has no data or mms. i have added an apn from my sim card in a galaxy nexus that gets me edge service. i have found band selection in the service menu but non seem to make it any better. I'm sure LTE won't work but thats ok. as long as i can get 3g at least. do i need to flash say the att s5 modems? if so how? i have the modem file and another already extracted from the att firmware. thanks in advance.
Samsung Galaxy S5 SM-G900i branded telstra
i think firmware ANE1 4.4.2

Using a foreign handset on a system will never give you perfect coverage. That is by design, as both Samsung and carriers want to lock you in, not make it easy for you to change carriers. Or do so without buying a new phone.
The specs for your variant suggest that it has full coverage on ATT's 3G bands and partial coverage of their LTE allocations. You don't need an ATT modem, just make sure that your firmware is recent - which it will be by definition, as the S5 was only released a few months ago.
Unfortunately you didn't provide much detail, in particular whether you were roaming or a regular ATT customer. Things that you might check in general, that your phone doesn't blacklist any ATT MCCs (roaming restrictions). That you have the correct APN information and that your ATT SIM is properly provisioned for LTE.

Thanks for the reply. I figured it out. In service menu, I was picking compatible gsm bands. Back to network screen in settings, had it on gsm/lte only. That was giving me edge. Read more into wcdma and used network mode wcdma/gsm. That gives me H or H+. I know I won't get lte but with that network mode and another apn, I'm satisfied with the end results.
It sounds like you inadvertently blocked coverage with your previous settings. The default setting is automatic band select which should have worked fine.
Glad you figured it out in the end.

Yeah. It was the apn that was hurting me. Default it used the wap.cingular apn. I put my sim in a galaxy nexus and used the apn that gave me. Plus changing network mode. Thanks though!
I paid to get a T-mobile galaxy s5 sim unlocked so that I could use it on At&t. I'm located in the US. I took the sim out of another non-functioning at&t galaxy s5 and put it in the t-mobile one. The sim unlock code was successful, and ever since then my calls and texts have been working just fine. However, the mobile data connection is not working and I cannot seem to ascertain why this may be. I have tried scanning for networks and automatic network selection through the settings --> more networks --> Network operators menu. Mobile data is enabled. I have a data plan through at&t. Wi-fi still works. Any ideas on how to fix this issue? Any help would be greatly appreciated. I was hoping that rooting the phone may help the issue, but I am new to this concept. As I have gathered, only certain models of s5 can be rooted as of yet, and I did not find a thread on rooting the G900T model for the s5's. Thanks for any help!
I think you must set the APN from Setting. Ask the AT&T providet for the APN.
I have looked all over the forum for a reliable answer but have not found one. I have a Verizon Galaxy S5 that I am running on the Straight Talk Verizon 4G network. I would like to change the APN settings to reflect the Straight Talk settings rather than the Verizon settings but everything about the APN settings is greyed out and nothing can be changed or added. The + sign is also greyed out which does not allow me to enter a new APN. I am running Lollipop OS on the phone.
Any help on solving this problem would be greatly appreciated.
The straight talk service uses the verizon towers because you have a verizon sim, i dont understand what you mean by reflect the straight talk settings? Just curious what you're trying to do because I have APN issues on certain roms and someone just helped me to where i was able to get the right settings....
I have a Verizon Galaxy S5 SM-G900V running rooted OK3 Lollipop 5.0 and i had the device brought in as a BYOD to MetroPCS. I currently have
Calling
Texting
Data
1x
EDGE
HSPA
HSPA+
4G LTE
however the only thing that does NOT work is MMS. I've tried so many combinations on the APN settings with no luck at all. Also If anyone has the IMS settings to allow VoLTE on MetroPCS that would be AWESOME
MMS fail to send or receive on all data modes
Bump for justice? Anyone?
I'm coming from echoe on an att S7E. I have fixed the MMS and used multiple ATT APNs but I am only receiving H or H+ and not able to get LTE. Does anyone have a way to fix this? I haven't used a Verizon rom before, the only thing I could think of was changing the APN. LTE works perfect for me on the Echoe rom.
U downloaded it on AT&T Galaxy s7
There's simply no way to get the Verizon firmware to work on the AT&T networks, it's hardcoded to use bands that at&t can never use, this was found by those using the Verizon nougat beta,
