Just a heads up to any BT customers who are low data / minutes users.
BT Customers can get a BT Mobile SIM for £5pm (I believe 12 month contract) with 500mb data, 200 minutes and unlimited texts.
Topcashback are currently offering £50.50 cashback on this SIM, BUT reviews are mixed re: tracking - must clear cookies and use a different browser to ensure it tracks. Personally I have never had a problem with cashback tracking but highlighting it to be fair :)
So that's £5pm x 12 months = £60, minus £50.50 cashback (or more depending on your membership type) = 79p per month overall.
If at least one person benefits I'm happy - enjoy :)
