Chitter Chatter, the T-Mobile specialists, have an attractive offer that might be a suitable alternative to the highly popular £10PM deal from giffgaff. Especially if you talk too much.
For £10PM on a 12-month SIM only contract, you get a monthly allowance of 600 minutes, 500 texts and a variable booster that can be changed every 30 days. There are seven different boosters, including unlimited texts and unlimited internet.
If you fancy more than one booster, you can add more at £5.10PM.
