Not sure whether this question has been asked before ( apologies if it has)
If I keep a spare cheap phone in the car for emergencies is it possible to have the same number as my main mobile phone ?
I think you will find that the only way you can get two sim cards with the same number is by registering as a Company and paying a massive monthly rental, cant remember at the moment which provider has this plan at the moment but is possible but at a cost.
