Iphone As You Go

[outrageous]

My Sister who lives abroad has an Iphone 5s and wants a Pay as you go option here in the UK which she visits on a regular basis ... as I am on a contract I dont know ... I need one that can be topped up when needed and will last over a long period of time ( as top ups might be every 3-4 months ) also the best deal for Texts // Calls and of course roaming so she can you the Imessage whilst out and about....
Any help very much appreciated Thanks in advance

My iPhone is on Orange - I get loads of free calls, texts and Internet for £10 a month and I just top-up online.

Hi Sherrardk ... When you top up does this expire after a time or would it keep the credit if you didnt use your phone Thanks

It lasts a month.

I was informed by Vodafone that, because of a shortage of phone numbers, any SIM not used for 3 months becomes extinct. This is a government ruling, not just Vodafone.

My guess is the best deal for what you want is with Three .. have a look !

The first thing to think about, is - is the phone unlocked? That will dictate where you can get a SIM.
