I've had a look online for EE PAYG SIMs, but with all of them the credit seems to expire after 30 days. Does the 1 year one have a particular name?
i am not sure about rules on here but i can be moderated if so
only seen them on ebay (reputable sellers) you can just search the number below
ebay item 191702408420 is the only listing on there that is £80 EE 24GB for 12 months
or a £25 3 data only sim that is 12GB for 12 months , item 201557825689 (witch is surprisingly cheap other sellers are doing same one at £35-45)
ebay "12 month sim" and limit it to Sim Cards category, you see 24GB for 12 months on there and others
i would ignore the t-mobile unlimited ones as they have a monthly 1GB high speed cap (once 1GB has been used its slowed down in the day time)
