Re: Using Iphone 5 Unlocked from O2 on EE for 4g - NIGHTMARE!

Whoever told you that is wrong.
The iPhone 5 works on band 3 LTE which is the same as EE and Three use.
O2 have now farmed out some of their old 2g frequency so you can also get 4G from o2 now in some areas on a 5.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.

Currently using:
OnePlus 6 (O2 & Sfr), Z3 Tablet (Three UK), iPhone 8+ (EE)
