Virginmobile are emailing their P & G customers with an offer of unlimited weekend texts.
The terms are:-
"Just top up £10+ during the week and you’ll get unlimited free texts all weekend! You can use them to any UK network, any time. It’s that easy! So, if you top up between Monday & Friday you can text like mad all Saturday and Sunday!
As Vodafone offer the equivalent for a weekly spend of £2-50, that's not much to write home about - except that you still have your £10 intact at the end of the weekend.
