If you remember back to the distant past of early mobile phones... does the phrase "dual band" mean anything?
Basically O2 & Vodafone work on one frequency and Orange and T-mobile are on another.
The phone in your Volvo is not "Dual band" and so will only work with Voda & O2 (and anyone who "borrows" those networks such as Tesco).
Three won't work either as they only allow 3g phones on their network.
