No I have not used that site , pointless having a posh phone here as we get no signal at all, my mobile is kept for when we are out in the car , It is an Aldi Workzone brick , takes two sims on different tariff suppliers and also has an sd card for storage, camera and torch, totally waterproof and shock-proof, designed to survive building site abuse. I have an old Virgin sim that I put £10 on 3 years ago and still has £1.70 on it , and a new Tesco sim.
