https://community.ee.co.uk/t5/SIM-cards-Porting/Sim-card-query/m-p/1280560#M38180 <P>Ive just bought a new iPhone through EE. My old phone is broken so I can use it and its quite important I get a new one set up ASAP. I was with o2 before. I am still waiting on my new EE SIM card. Am I able to put my old o2 sim into my new phone in the meantime, or will this cause my new phone to become locked to o2/make it difficult when my EE sim arrives?</P> Wed, 02 Aug 2023 17:07:29 GMT daisjn 2023-08-02T17:07:29Z https://community.ee.co.uk/t5/SIM-cards-Porting/Sim-card-query/m-p/1280560#M38180 <P>Ive just bought a new iPhone through EE.

Your new phone won't be locked to anything.</P> Wed, 02 Aug 2023 18:00:33 GMT https://community.ee.co.uk/t5/SIM-cards-Porting/Sim-card-query/m-p/1280596#M38188 XRaySpeX 2023-08-02T18:00:33Z
