I've borrowed an Android phone so I can decide whether to buy one. I have a GSM SIM without a data plan, but I am using Wifi that is broadcast from my other smartphone which does have a data plan.
The phone's GSM signal icon has a tiny "R" that indicates that I am roaming -- why?
My phone is an HTC Desire Z with (I think!) Android 2.3.
Settings > Mobile Networks I have these settings:
Data enabled = unticked
International data roaming = unticked
National data roaming = unticked
Use only 2G networks = ticked
The notification list sometimes shows me a message that is too long to be displayed, but some googling tells me that this is the complete text:
"You have lost data connectivity because you left your home network with data roaming turned off"
The notification list also shows that I am in fact on the correct network: My SIM card is from the provider "bob" and the phone shows that I am on the "bob" network.
Am I consuming anything related to roaming? How can I ensure that I will not use roaming?
