Hello All,
Im currently with id mobile on sim only plan and Im considering to upgrade however the same phone with id if I upgrade through carphone warehouse it works around £500 cheaper than upgrading through the id app. The question is here if i choose the carphone warehouse plan which is with ID mobile plan that is £500 cheaper than the same plan if i upgrade through the app, How do i get to keep my existing number that i have with ID on my existing plan to migrate to the new plan?
