I've had this phone for about 3 weeks, switched from an A20. Everything worked fine until 2 weeks ago. I could receive calls and texts, but can't send or make calls. Everything else worked,, over wifi and with data. I have a new SIM card, restarted, reconnected to the network, called my carrier. The carrier opened a ticket, then said they couldn't find a problem. The next day it started working again, until yesterday. Same thing happened so I did a factory reset. I only downloaded the apps I use everyday and it worked fine again, until just a little while ago today. I sent a text, the person replied within 10 minutes. I tried replying right away and that text wouldn't sent. About to pull my hair out, never had a problem with the A20 until I ran over it with my car by mistake. Anyone else have the same issue?
