Everyone will recommend their provider but Ofcom data clearly suggests Three are the worst of the big ones to deal with.
Not being pedantic, but your post suggested that you can’t use Three in a brand new iPhone. To be honest, I’ve never had a complaint about them, although upgrades can be time consuming…
I’ve never had cause to put them to the test customer service wise. I purchased a £10 contract the other day for my son, job done in 5 minutes. Arrived the next day and I ordered it the night before. I suspect it’s a bit like car reliability surveys. There’s not much between them. Vodaphone refused to cancel a contract bought for a friend’s son who committed suicide. I don’t think any of them are paragons of virtue.
