3G (data): ON and OFF. When?

[bruleke]

This is annoying me!!!

I have an iPhone 4S and a 3G data plan. It happens that sometimes the 3G icon disappears (even in an area that HAS 3G signal) and I cant access internet. Then, for some reason, it appears again like if nothing had happened.

My concern is with the 'find my iphone': if I lose/get robbed someday, how can I trust it?

I've called my 3G operator and there's nothing wrong with it.

So, my question is: is there anyway to make iphone keep 3G on all the time? I know that the "phone data" (or something similar - my iphone is not in english) has to be turned on (and it is), but is there anything else I should do?

Try reseting your network settings.
If that doesnt work try a restore with itunes.

Try going into Airplane Mode when it happens. Maybe where you are just has spotty 3G service or your phone's antenna has some problem receiving it properly. I'd try a restore as new and backup and if it persists, it's probably hardware.
