I received my iPhone 7 128GB Verizon on launch day, and since then I've had the hardest time keeping LTE or even 3G. I will unlock my phone with 1 bar of LTE and then turn on and off airplane mode and receive a whole bunch of texts and notifications. Ive never had this problem with any iPhone. Does anyone else have this? Is there any fix? I get "no service" a lot also, even though I'm at my house or office, where I usually have 2 bars of LTE. Should I take the SIM card out of my old 6S and plug it into my 7? Would that hurt?
