Sky use o2, probably the worst network nowadays but Vodaphone aren't far behind. Best network is EE, next is 3. All networks are good in cities and most large towns but every network still have plenty of blackspot areas with zero signal.
I had sky for all of 2 weeks, cancelled as the speed of data was about 0.5 mbps. Since been told although it’s piggybacking o2, they meter their connections so it’s dog slow.
I have done a pre-order for a pro max, but on the pre-pre-order(!) I was refused the Barclays finance. Bit confused as I have a decent job 1000/1000 rating on ClearScore and two previous completed phone loans.
Only thing I can think of is last year I ordered a 14 on behalf of my daughter through Vodafone, the app was a bit laggy (Black Friday deals) and got a mail to confirm delivery in two days, but didn’t turn up. Called to complain to be told due to a technical error my order had been cancelled, so got batey and just did a sim only, then went directly to apple. Ordered phone, got to checkout was refused credit, checked ClearScore and had 3 hard searches from Vodafone! Daughter, teen on minimum wage, no credit history, did it herself and immediately accepted (better for her so wasn’t bothered really). Moaned to Vodafone was told nothing they could do, then searches mysteriously disappeared!
Anyway, paid this one on credit card (will pay off asap), saw they had a mag safe case so added that too. Later had a dispatch notification, well happy, if a bit surprised, but case arrived next day - phone scheduled 9-16 October *sigh*
