Yes, it is! Your current post-paid number will automatically transfer to Circles.Life in January, 2018 to your Circles Switch SIM. We will send you an email towards the end of December, 2017 with the exact date and time that this transfer will happen.
Once this transfer is successful, your SIM card will automatically have the full Circles.Life experience enabled.
If for whatever reason you want to cancel the automatic transfer of your number to Circles.Life and avoid being billed, ensure you cancel your Circles Switch Trial in the CirclesCare mobile app before 23:59 on 31st December, 2017.
