Is MobileFun a reputable site?
I've bought loads of stuff off them over the years, only one or two minor problems but were able to sort them.
I've purchased a Samsung Gear S3 frontier from them and wasn't expecting it to be available until next week, I was surprised when I had a dispatch email from them yesterday, the only problem now is it's stuck in DPD's Cardiff depo, I've got to wait until Monday
