get frustrated with signal loss. My kids with their phones which are only 3g have no problem. My signal of 3g or 4g or sometimes even the plain signal is all gone and even powering off then on doesnt help. THought maybe it's just because the 4g signal isn't strong enough in my area but since I loose all signals many times this can't be the only problem. I am new to smart phone and never had problem with other *granny* phone. My kids have no trouble. Verizon says I can buy a $250 signal booster. but not about to do that. Any other suggestions? thanks.
