Solved: Change sim from O2 to different provider

ej5 · ‎15-03-2024

I have a very old phone and want to use it with a different Sim (from Sky) in addition to my current phone with O2. My phone number seems to be attached to the very old one as well as the current phone, and I am not sure how to change sim to a sky sim in the old phone without upsetting my current phone

This is not O2 and we are all customers here similar to yourself and cannot answer account type queries.

@ej5

Have you tried the sky sim in the phone as it may work without unlocking?

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:
Pixel 7a (O2 & Lyca), One Plus 6 (Sfr), iPhone 12 Pro Max (Vodafone)
