The old Motorola is kind of robust. I've told my wife she can have my American sim and take it to the US soon.
I keep my long-standing number there since banks seem to insist upon it. Wire transfers for instance are finalized by putting in a number they TXT you. Very stressful here, cos the US connection in east Essex can fail without warning.
Can't download much in the way of Apps for some reason and they, MR, wanted a fortune to upgrade the OS. When I'm up to speed on the Samsung Galaxy quad thing I'll be more relaxed about re-setting the old one. Right now, it's got both UK and US phone lists and copies of my novel and . . .
I'll do a factory reboot and hope. It would be nice just to leave this one in the car since the radio is very clear on phone calls. I'll pop back to JB to talk about the latest photos of inside my steering wheel. Took them yesterday. Not a hint of any way those mass of buttons could work. Car radio shop in Colchester says they are Bluetooth, but it would still need to be powered - but could have windings in the rubber molding of the wheel.
Never had much success in getting into its software via a PC. Trouble with having one of the first Android in the world. First hour of first day. Huge promotion then c

p OS.
The Samsung shard of metal and glass is not good for my old hands. It's a bit like trying to hold a small wet fish that seems determined to escape. Case on the way.
