Hi,
My mum is currently on CDMA and she's going to the UK in a few months. She also has an old GSM phone with no SIM. Is it possible to get a "roaming SIM" like the old WorldMode phones had?
I'm aware that a Vodafone or 2D SIM is always an option but that'll result in her number changing and I don't want to confuse her too much if I can help it :)
Thanks.
