Any question answered...

Is it possible to have 2 SIM cards with the same number? I'm on PAYG with 3.

Reason is that my new phone uses a micro sim, and my old phone uses a regular SIM. I would like to be able to use my old phone when i'm on long rides as it's smaller, has a better gps and longer lasting battery.... and doesn't matter if I smash it!

Do you need to receive calls when you're out, or just want a phone to call the rescue vehicle? For the latter case, I just use a PAYG SIM in my disposable handset
