hi i am thinking of jumping ship from my one plus 3 to the 7 plus ,if i get one from o2 with the lowest data so i can put my EE sim in ,,what i want to know will it then be locked to EE.
If you buy it directly from o2 it will most likely be locked to them. Directly at full price from Apple means unlocked. I'm not sure if this is the scenario in the UK though.
