PAYG sim with non expiring credit/back up sim wanted

Half_way

At the moent i have two sim cards activ, one on three, and another on T mobile, as a back up.
however lately my T mobile pay as you go sim has had a lack of signal iin the same places as my main three sim.
I have no issues with Threes signal, but as with all networks the coverage isnt universal, and I need a good back up pay as you go sim for ocaisonal use ( web/text/e mail+ voice) on a decent network that preferably has credit that doestn expire after a month, and even better ( if it exists ) a data bundle that lasts ie you pay for 500mb/1Gb and you can use it up over however long you like ( ie within 6 months at least)



The places that i have been to with no usable Three/T mobile signal usualy show a good 02 signal (but they are expensive) and a moderate vodafone signal.
any recomendations?

You need to define what "occasional use" means to you. It means wildly different things to different people.

icardmobile use the vodafone network, 6p/min mobiles, 3p/min landlines, 5p per text message, 10p per MB, free voicemail.

If you may be leaning towards more data use, and are happy with the 3 network, simfiniti lite may a consideration. Landline - 5p/min text message - 7p, Mobile - 10p/min, data only 2.5p/MB.

If your back up needs to be on a different network, Tesco and Giffgaff use 02.

All have no credit expiry (like most PAYG services) provided you make periodic use of the service - typically every 90 or 180 days.
