    Hello, I'm new to android central and I need help on how to fix this issue I'm having with my S5. I had this for a year as a 2 year contract phone and after 10 months I damaged the AMOLED display and I hadn't used it for 2 months. I had to switch the sim card to the lumia 520 4G GoPhone to make calls and do my everyday tasks on my phone. After getting my phone's screen repaired for 2 months I switched the sim card to the S5 however I'm only getting 4G signals, is this because my sim locked to the GoPhone's signal? I never accessed the charging port of my s5, just replaced the display itself. By the way I had to put the APN settings on custom (that means the 4G LTE APN settings for AT&T) instead of default APN since I don't get any 4g reception on it, just signal bars appearing and calls/texts only, no data. My 4g signals in my S5 work just as fine as Lumia 520 however I just don't receive any LTE. Any solutions to this issue? I'm pretty sure that it's my sim card not the cellular antenna of my phone.

    Welcome to Android Central! Have you asked AT&T for any assistance? Can you delete that APN setting, then reenter it again?
