Hi all, My son has my (bought unlocked from Apple) 5S. I had it on 3, then gave it to him and he;s been using it on Vodafone. He's just switched to EE, but can't for love nor money get the internet to work. EE have said it's an issue with the phone and in fairness his SIM works fine in another iPhone. They said they've pushed an update to it and that once he received it he should restart the phone, but that didn't help. He's also reset the network settings-all to no avail. Help!
