my dd's lost her contract phone and i gave her an old one but for some reason she can't get a signal in the house (never had this problem before and i'm on vodaphone and can get a signal no problem).

i suppose i'll have to buy a new phone to tide her over till january when the contract runs out and she gets a new one.

can anyone recommend a cheap one from argos or somewhere like that??

Asda sell mobiles on the Asda mobile network which are fully unlocked and unbranded.

As do carphone warehouse.

Am sure they have/had a £10 one!
Just ask which are unlocked.
They cross sell so a high percentage are,

i wouldnt want to be on asda mobile because i already have a replacement simcard from the phone she lost. i just want one to take an orange contract sim

You wouldn't be on Asda mobile, that's the beauty of it. They are pre pay phones, but are supplied unlocked for use on any network so bin the Asda sim and use your existing sim in the new phone.
