Beware of the trap and make sure your phones are not faulty. Do not use ee or plusnet. They are as bad as each other. Use Vodafone I was sold a faulty phone and because I didn't call within the first 30 days, all they can do is repair it. I have been past from pillar to post within ee from person to person. Then past again to Samsung. Samsung repaired it and said keep an eye on it and if problems persist to call ee and ask for a new sim. Ee is now going to repair it because that's all they are offering. They said they would repaired it and if problems persist they will keep repairing it until it gets to the point that they deem it unrepairable. I wouldn't get a like for like phone whilst the phone is sent for repairs and I would be without this phone for a few days at least. I have explained to them that after everything I have had to do, everything I have lost from a hard reset like old whatsapps etc. They don't allow me to move off with another company unless I pay the rest of the contract. I think this is out of order after they accept that the phone is faulty. Beware
