So found a good deal on uswitch for the iPhone 11 with 02 ( over £10 cheaper than 02’s offer via their app ) my contract is up on the 17th June 2020. I am due and upgrade with 02. Will it be ok to go via uswitch for the upgrade? Thanks in advance.
Yes, as it's an upgrade you can just do it with them and everything will change over automatically.
