Replaced sim card reader; can call and text,but not send/receive pics no internet connection

Hi. Replaced the sim card reader on an unlocked Galaxy S4. Since then, I lost mms and internet functionality. Cricket network symbol, my current network, is on and calls/texts are good. In Mobile Networks >Access Point Names , APNs shows 2 choices: ATT phone with related settings (not sure if this phone was formerly an ATT phone) and AioMMS, which is for Cricket settings. ATT is showing as the chosen APN, but it cannot be deselected or edited. AioMMS cannot be selected because there is no radio button for it. I can tap and edit AioMMS, but again, I can't choose it. Help is much appreciated.
