Unlocking with Three
Does Three lock phones?
If you bought your phone from Three after December 13th 2013, it won’t be locked. That goes for pay as you go phones as well as those bought on contract from Three. Phones bought before this point will, however, be locked to Three.
Is there a charge? Does a time-limit apply?
No charge applies. Three will unlock your phone free of charge. Three does not enforce a time limit. You can unlock your pay monthly phone at any time during your contract.
How long does it take?
Expect a wait of up to 7 days.
Phone 333 from a Three mobile or, alternatively, you can use this online form.
