A:AnswerI travel rural west tn. There are several towers about west tn. So far I have been able to always text. I get more texts than calls anyway. Calls seem ok. But having used cell phones since 1990, there have always been dead spots. Phones are two-way radios.
A:AnswerI don't know if J is for junior and yes they are on the market cause I bought mine from best buy and I do order from Amazon and they have them on line. I cant really say if their built for kids for I just bought mine a month ago and for me the price was right but this not the phone that I originally wanted. It is a smart phone. Has face and thumb recognition and quite a bit of stuff on it. The phone is slippery handling it and I bought a rubber plastic type case for it. It would be best if you go to best buy and talk with a sales associate and maybe they can tell you.
