Bsnl Error, No service on 5 bars?

I have an iphone 4 and i live in India, i was using t24 and recently ported to BSNL, everything was well since today, i can receive incoming calls but can't make a call. I tried to check my balance and it says "Error Performing request, No network service " i have rebooted my device and tried all sorts of stuff. I can't even call ' call center ' because i can't call, but i can receive, thats weird. I also tried adding currency, didn't work. Can you suggest me on how to fix this?

When did you ported your number?
6 months completed means, your plan has been expired.
or else submit your proof to bsnl office.

And one thing
Also check caller id=> select "show number" option on your call setting.

It is easier to get a signal than to send one the sent signal is a lot stronger than your phone can put out

  • Trying to restore jailbroken iPhone 4, getting Itunes error 3194 and error 11 I want to wipe my jailbroken iphone 4, on ios 5, so i can update to ios 7. I used tiny umbrella and managed to get past the 3194 error, but then I'm getting error 11. I have tried to erase and reset through the phone only, but it simply shows an endless loading ticker, and not the apple logo and loading bar. How can I reset my phone? Thank you for anyone who can help! I also have the latest itunes
  • Sprint Iphone 4 goes from 5 bars to No service and Searching? I called sprint and they tried everything on their end and told me to reset the network settings, even resetting the entire phone, and nothing helped. I read somewhere that the antenna is touchy on these phones and wearing a case may help? I would like to hear any fixes and if anyone else has had these issues. It worked completely fine the first day I had it and then it just started losing service for no reason.
