Although I have a lovely Nokia 6300, which I take everywhere with me, I bought a smart cheapie mobile from my Sains
- to just kinda "leave hidden in the car" in the case of Paddington Bear emergencies (marmalade sandwich will be in the glove compartment
)
However, as lovely as it is and as cheap as it was, it is "tied"to the Orange network
- I have removed the Sim and put another one in and it knows!! it detected that it wasn't an Orange Sim card 
I don't want to be tied to Orange, as I have a nice O2 Sim card with £10 on it, going spare and I can just copy over all my phone numbers and contacts that I might need in said "emergency"
Is there a secret technique or something that could be fiddled with, to make the 'phone network free again?? There must be something that makes it recognise the Sim card but what??
There are no memory cards in the Orange phone, just the Sim.
