we are using two different accounts. and i mean it wont connect on its won after when it disconnect. we will have to go back to setting and enter Google name and password all over again. it wont save the login information
Restarting the phone didn't help? Shouldn't have to re-renter the username/password. You can accomplish the same thing by un-checking and then re-checking the Allow 3G/4G calling checkbox. It's pretty much forcing the app to re-register. We depend on a callback from the phone to tell us when the network is back up. My guess is that callback isn't coming, that's why I suggested restarting the phone to see if that fixes it.
Otherwise we can likely make a change to poll the connectivity state instead of depending on the callback and make that an option in the next release.
