I moved to a new location and my iphone6 coverage is down to almost nothing dropped calls and only one bar - I am in zip code 05055. Should I change to another carrier? Other people have ATT and it seems to work okay.
I Believe that is a choice you'll have to make. If you are on contract, there will be ETF to leave early but you can keep your phone which will work on ATT. If you are on Edge, pay off the balance and your phone will work at ATT.
To stay with Verizon, you can get a network extender.
Also also since you are in marginal area, turn off advanced calling it LTE voice on the iPhone if it is on. That may help.
