Yes you can! After you have requested to transfer your number during the Sign Up process, you can continue using your current SIM from your future ex-telco until your Circles.Life porting process is complete (you will receive updates from us as this is happening).
When you receive your Circles.Life SIM card, you will be given a temporary number. This number will only be a placeholder until we have successfully transferred your existing number onto the Circles.Life network. This is to limit the disruption on your current number. If you wish to start using our services before the transfer is complete, you can go ahead and pop your Circles.Life SIM card into your phone and enjoy the data right away!
