My phone doesn't have any cellular phone functions...but it CAN send text messages and access data. Has this happened to anyone else? I've gone through three Samsung Galaxy S5's in the past three days, the last two have this problem and the first stopped working all together. I've had new sim cards put in, ive done hard resets on the phone, i've rebooted the phone, done battery pulls, and tech support has reset the signal to my phone. Nothing has worked. (I just "upgraded" <- lol.... and my old phone IS turned off.)
