How to Transfer or Port Your Number to Circles.Life

Switching to Circles.Life is simple, and you can keep your existing number without any hassle. Follow these steps to successfully transfer your number:

Step-by-Step Guide to Port Your Number:

1. Receive Your SIM Card:

   Once your Circles.Life SIM card arrives, you can start the porting process through a mobile browser. (This applies to both individual users and the Primary SIM holder under the Family Plan.)

2. For Family Plan Users (Sub-SIMs):

   • If you’re a Sub-SIM user, you’ll first receive a Circles.Life assigned number sent to the Primary SIM’s registered email once activated.

   • After receiving the assigned number, follow these steps:

     • Download the Circles.Life app (ensure you use a mobile phone for this step).

     • Log in using the assigned number.

     • Navigate to Profile → Account → Port-in Number.

     • Enter your existing number’s details from your previous telco and complete the porting request.

Important Things to Know Before Porting Your Number:

• DO NOT terminate your existing number with your current telco before the transfer. Circles.Life can’t process the port if your number is already canceled.

• Your current telco account will be automatically terminated once the transfer to Circles.Life is complete.

• No termination fees apply if your existing telco contract has already ended. If you’re unsure about your contract status, it’s a good idea to check with your current provider before initiating the port.

• Changed your mind? If you initially chose a new Circles.Life number but later decide to port your existing number, you can do so directly through the Circles.Life app.

• Note: You cannot port in more than once within the same month.

Pro Tip: The entire process is designed to be smooth, but it’s always best to keep your current SIM active until you get confirmation that the transfer is complete.
