Didn't see it posted so posting it just now. Called customer service for an upgrade and they offered me the one plan sim only including:
* 2000 minutes (anytime, any network)
* 5000 texts
* All-you-can-eat Data
* 5000 Three-to-Three minutes
* Free PAYG SIM for a friend
for £15 per month with a 12 months contract. This contract is available at £25 per month on the website.
For those who are due an upgrade you should call 333.
