I have just requested that my iPhone 4 be unlocked from Optus so that I can take it overseas next week.
I plan on buying a sim card in London, and will probably need another in Paris and another in Rome so I can text home.
I realise each time I buy a new sim I will get a new number, but I just don't want to risk any large bills due to my getting things wrong with my own sim from Australia.
Each time I get a new sim, I will send a text to my brother (moving into our house) and he can pass it on to the boys.
Am I correct in thinking I need to turn off both "cellular data" and "data roaming" in order that my phone doesn't drain the prepaid sim if it keeps trying to connect to the net?
Do I also need to turn "enable 3G" off?
I don't plan on checking emails (or Somersoft ) while overseas, but really just want to be able to have the phone available in an emergency, or if we need to call ahead to an hotel to say we are late and please don't lock us out.
I have apps I am thinking of buying for a few dollars for each city, but they don't need to connect to the net.
If we need to connect to the net for any reason, can I just turn on the "cellular data" to connect, and then turn it off when finished?
Next question (probably a dumb one) is that with a prepaid sim, am I guaranteed that there is no way that I will accrue any charges to my Australian account?
I know I'm a bit paranoid, but I have heard so many stories about nasty surprises with the next bill, that I don't want to have to think about it.
