Yeah not the best signal but even when im on 1 bar i can hear the person perfectly and ive never had anyone saying they cant hear me or asking me to repeat anything, so even with 1 bar its fine.

And im talking 3G signal, if it cant find a 3G signal then it goes to 2G or whatever it is and its almost a full signal then.

Never really had a problem where i cant get a signal at all to be honest.

I guess it depends where you live, but 3 are meant to have the best coverage
