Here's a great listing if you're looking for a cheap PAYG sim or want a lost cost way of testing out the EE network. for just 99p (including delivery) you can get a PAYG multi-sim pack which includes £5 of credit. Putting the sim card in your phone will activate it and deduct £1 of that credit to activate the new Talk & Text pack, which provides 25 mins and 50 texts for 7 days. After that, the package is automatically renewed for the same fee, although it is possible to cancel the package if you would prefer to use the standard PAYG rates. Thanks to Adilafridi40 @ HUKD!
