Which UK SIM cheapest to activate from abroad just to have a UK number?

I confirm it......Giff gaff is the best solution.
I find some one that send it at my home for free. I recharge and use once in England. Then i send an sms every six months and it's still alive and very cheaper

I have kept a GiffGaff card alive for more than a year without visiting UK or topping up. However, I don't think receiving an SMS is sufficient to do this currently. This used to work. The policy now states that you must receive a minimum of 4 calls of at least 10 seconds duration each. Because I am not in the UK, this would mean roaming charges if I left the SIM in an active phone. Instead, I make the calls with the SIM out of a phone, so that they are forced to Voicemail. This seems to work!
