Tesco is currently offering 750 minutes, 5,000 texts and 2GB of Tesco Mobile data on a 30-day rolling deal, all for £12.50 per month. Oddly, that’s a higher allowance (more data) than the £15 deal. No complaints here!
Five thousand texts per month equates to 166 per day. If you struggle with that, you've got a problem, friend.
Tesco Mobile uses the O2 network.
