The best £10 mobile deals that I can find at the moment are:-

This is a network which I have used for the past 5 years, and have had no issues with.
You get Unlimited Calls and Texts and 3GB of 4G Data for £10/month
Smarty
You get Unlimited Calls and Texts and 4GB of Data for £10/month, plus refund of £1.25 per GB of unsused data!
So the basic package costs £5 for Unlimited Calls and Texts and £1.25 flatrate per GB of data, and you can choose 2, 4 or 8GB of data. (That’s around £0.0013 per M, a great bargain).
So if you buy the 8GB package instead of the 4GB, if you only use 4GB the refund of £5 will make this cost the same as the 4GB package, so this package makes sense if your datause fluctutates between massive and next to nothing.
The only catch, no Data Roaming at present.
Both of these are month to month, no contract details and both allow you to migrate in your existing number.
