Just updated my mobile and transferred my SIM to the new one. There's nothing wrong with the old mobile so I'm looking for a SIM for it as a backup. ASDA or Tesco do a SIM pack for about a fiver that has £10 credit on it, does anyone know of a better deal. One that credit does not have to used each month but kept alive once ever six months by a text. Any other network that might be OK - Tesco or Virgin?
I have a ten year old SIM but I think that needs £10 to re-activate it?
Edit changed and for but ... kept alive...
