Or can someone recommend a reputable supplier of refurbished iphones. My daughter always has my old iphone when I upgrade, but the 5 she has now is on it’s way out.

Please don’t recommend an Android alternative! 😀

No idea how often the come up.

I pay £11.50 a month with EE for 3gb data and unlimited everything else.

Although tbh that gifgaf deal looks ok providing that you get the coverage you need. I can’t get anything other than EE where I live (pretty good in the peaks too).
