I have seen a few postings mention this.

This brings up the debug screen (service mode)
I unlocked my T-mobile Samsung Galaxy S4 and I am trying to use it on an AT&T mnvo but I do not get any data service. So I am wondering if the bands need to be changed in this menu or some other menu on the phone?
Does anyone now this information? I am trying to determine the cause of no data on my Red Pocket sim card. I have the APN Settings correct and registered on the Network but still no data connection.

I have a galaxy S3 (SGH-I747) originally on Rogers form Canada. I bought an Un lock code and unlocked it. The phone shows signal, makes calls and SMS, but NO 4G and NO network access. (internet pages don't load when disconnected from WiFi)
Under Mobile Network I cannot connect to ATT's network. Does anybody know what I'm doing wrong? Or is there a ROM i need to install after I ROOT the phone? Do I even need to ROOT it? (Sorry in advance, i come from the world of Jailbreaking, but have rooted Droids in the past)
Thx!
I'm not an expert, but you probably need to check your APN settings, and change them to AT&Ts if they aren't already. You can check this in Settings -> More Settings (in Wireless and networks section) -> Mobile Networks -> Access Point Names
I don't know what the AT&T settings should be, but you can probably find it easily enough. Also, you might want to Shut down the phone, remove the SIM, reboot without a sim, then shut down and put it in again to make it read the APN settings from the sim
Try flashing the ATT rom and see if that makes it work to start.
Got It!!!
I had to manually add my APN settings. I was over looking the button on the bottom left to configure it.
Thanks for the help!:cyclops:

WAIT 90 SECONDS THE REBOOT
VOILA! TMOBILE LTE.
Now i have succesfully unlock The Verison GS3 to Tmobile on Edge is there a way to port that radio. to get cell connectivity.
or if anyone want to try to tweak these settings to get more than just LTE connection. or get Voice over LTE working!
I do believe that you need the HSPA radio to make phone calls as T-Mobile does not yet support VoLTE.

What are you doing for apn setting? There are 3 for tmo-us that I know of. 1)gsm 2)lte 3)lte ipv6. You may have to down load an apn app. Apn manager pro worked well for me or offline sim apn database. Not sure what you use for network mode settings but use build prop editort open it up and find the settings telephony.lteoncdmadevice & telephony.lteongsmdevice use value 1 on both. Add lines if not there. This may open up more network types under setting/...network mode. Google build prop edit or tweaks to find more info. Good luck.
i535 radio/modem
Been thinking about you question to swap modems. Do not use the i535. The modem that would be ideal I believe is the r530m. That is metro PC variant. T-Mobile merged with the.... Do I need to explain more? Any how I can not say it will even work. I will say that T999L is no good. Found out first hand and still dead in the water with it. I would explore the APN settings and network selection modes with build prop mods before flashing. I am not even sure about the LTE bands and who has what and where. If I am able to revive my 530u I will see what I can find.
Where can I get the r530m modem? Can't find it anywhere.

So, is it possible to flash the R530M modem????
I know the setting was available in mobile network I part of the menu but it gone now. Tired the service menu code and seems AT&T blocked them out. Anyone figured out how to change down from LTE to HSPA

***SOLVED*** Thanks!
Hey guys I'm in need of the default settings for a Sprint S6's Testmode Menu. Specifically, the Network Controls, GCF, Preference Mode or pretty any way to set the S6 back to the way it came with Sprint plus the GSM unlock for T-Mobile. In settings/Mobile Networks/Network Mode was Auto before my mishap with the settings. I also had two APNS for TMO one for LTE data and the other for MMS and in service mode, it was set to Global. I changed stuff around in Testmode Menu and thought I had put it all back to how it was, but now when I set it to GSM/WCDMA/LTE, I will get GSM in areas I know for sure had full LTE. It will also say GSM/WCDMA/LTE in Network Mode through settings, which isn't an available option through there and which was originally Automatic when working. I wish to get back to the way things were. My phone was unlocked via GC Pro from an XDA member. I had changed the settings in hopes to improve my signal at homr because going to my neighbor's house improved signal. M changes worked, but randomly would say No Service. Anyway, please please help! If you have any other suggestions, that'll work to.
I unlocked my VZW g6 play by entering code in settings section to unlock phone (did not insert AT&T sim and wait for code request). It said code accepted but when I put in my AT&T sim I can't connect to their LTE network. It reads the sim, switches to global (gsm), and my network says AT&T with the proper phone number for that sim... But no 4g. I tried inputting the APN settings I found on several sites.. No luck. Same when I copied the APN settings from another AT&T prepaid phone I had available. No go. I called and asked for the APN settings from AT&T and they said I need to change the IMEI number on my sim to that of my g6. They said they did that for me. After power cycling the phone as instructed I still have no data service. Anybody have an idea what settings I need to use in order to use my AT&T sim? Or is that even my problem?
