Go into your phones "mobile networks" settings.
Make sure that your, Make sure that your "Preferred Network mode is: Global (This is important, change it once and leave it alone).
Turn off "Mobile Data"
Go into the "Access Point Names" listed under "Mobile Networks" and change your settings to EXACTLY as follows:
Name: T-Mobile US LTE
Proxy: Not set
Port: Not set
Username: Not set
Password: Not set
Server: Not set
MMSC: (I cannot enter url's yet however, this is going to be what you have found across the board on all sites for the MMSC which includes: "mms.msg.eng.t-mobile.com/mms/wapenc") Without the quotations of course.
Multimedia message proxy: Not set
Multimedia message port: Not set
Authentication type: Not set
APN type: "default, mms, supl" (do not enter the quotations)
APN protocol: IPv4/IPv6
APN roaming protocol:IPv4/IPv6
Turn APN on/off: Needs to be checked with a green check mark unless it is greyed out and checked.
Mobile virtual network operator type: None
Mobile virtual network operator value: Not set
After you have completed the setting exactly as above, hit the menu button and save the APN (Make sure that the circle for this APN is filled in green. Back out one screen, turn mobile data on, then back off and then shut down the phone. *Wait Five Minutes*
Turn the phone back on, turn on mobile data and (as hard as this is going to be) put the phone down and walk away! Set a timer for 10 minutes and have someone tie your hands behind your back if necessary!! Don't touch the phone..
At the end of ten minutes when you pull down the notification bar it is probably still going to say "no service" at the bottom. Even if it now says T-Mobile CONTINUE TO THE NEXT STEP if you would like this to work flawlessly..
Have someone call you or use another phone to call yourself. This is going to take several attempts (about 3 or 4) before it stops going to voicemail and the phone actually rings. ANSWER THE CALL, HANG UP..
Final Step: ENJOY THE LUXURIES OF HAVING YOUR PHONE WORKING PERFECTLY!!!!! YAY!!!
Note: When you make a call your phone is going to have to switch over on the networks for voice so it's going to ring an extra minute (don't worry it's normal). When you hang up the call it is going to take a moment for the network to switch back over to 4G LTE. Be patient and have faith in your success (It will happen). Don't start changing settings.
Good luck to all (Hopefully I didn't forget anything).
