I switched to Straight Talk and brought my own AT&T phone, using an ST SIM card. I have a Samsung Captivate Glide, Android version 2.3.6, Build number Gingerbread.UCKL1. The issue is I cannot receive MMS messages. When I go into Settings/Wireless and network/Mobile networks/Access Point Names, I have two APN's - ATT PHONE and ATT WAP.
I just got US Celllular to accept my Samsung Galaxy SII originally from Boost on their network. I just need either a ROM to flash my network settings or a way to force change the network settings and the setting specifications to change them to. Help me get it running and I can help you get your phone on their system XD
