I signed on one month plan a week ago, but my phone frequently shows no service , even a couple of times a day, quite often when I wanted to use it, it shows no services, is there anyone knows what is going on?
I signed in a 30 day plan two days ago, it worked well until i powered off the phone, after power on, it showed No service. I tried powered off a couple of times, it still shows No service, please help, thanks in advance.
