For anyone wanting to keep their own phone I think this may be a good deal.
200 mins calls to any mobile or UK Landline + 200 texts for £10/month with no lengthy contract to tie you into.
Free voicemail in the UK and free itemised online statements included.
"If you want all the great stuff a contract brings, but with no long-term contract, the Liberty SIM from Virgin Mobile is just right for you. It's the best of both worlds:
Pick up more minutes and texts than you would with a contract
Like more minutes for £10 than any other network. 200 minutes and 200 texts for £10 a month.
Keep your phone and number
No long-term contract - you aren't tied-in to a lengthy contract
Plus some neat extras like free voicemail in the UK and free itemised online statements
All you need to do is unlock your phone, slip in your new SIM and you're away!* "
