I managed to sort it today. You need an unlocked phone, a pay as you go SIM card for 3, you can get them from Poundland. Phone them up, 333 and explain what you need. You can then pay £10 minimum or upwards in multiples of £5 and your sorted. I’ve done £20 for 12g data, 3000 texts and minutes. You can’t phone Israeli numbers unless you put some money in a different account and the rates are extortionate, but it’s fine for keeping in touch with uk numbers, if they’re in Israel.
