I own a galaxy s5 (have had phone for months) and I noticed I wasn't receiving any calls or txt today except for earlier this morning. Went to go make a call to see if my phone was working and my phone told me that they couldn't find my account or something along those lines. I asked my brother to call my phone as well and he said it rang 3 times then went to my voice mail. Someone please help I have never heard of a phone self deactivating itself. Nor can I get in contact with sprint at this time and i need my phone for work. Have already did basic troubleshooting tricks with no luck. HELP!
