Ok so everytime I for example, send a text, I completely lose signal, it tells me SIM access required or something like that, then the signal comes back, and I have to resend the text. Or my phone will show the 4g symbol, then when I open an app, I will lose cell and 4g signal and I have to wait for it to come back. It happens no matter where I am without fail. Its like everytime I try to use it, it has to reset itself, which is horribly inconvenient. Also my GPS is always off. If I am driving down the road, it will show that I'm in the river beside me or something. I've had to start using the step-by-step list. It seems like it has to be something wrong on Verizon's part, not my phones. Do I just need a new SIM card? This has been going on for months now.
