Sure, you can request to keep your mobile number during sign-up at any M1 Shops | Store Location | M1 or by visiting www.m1.com.sg. You can use the temporary number we issued to you while we process your request.

 

Do make sure that you have completed your contract, otherwise, your current service provider may impose an early termination charge.

Usually, it will take a business day after your SIM card/eSIM is activated. We'll SMS you when porting starts.

Simply head down to any M1 Shop and inform our colleague of your request. Importantly, you must present the original identity document of the party who consents to the transfer of mobile number to you, along with a Letter of Authorisation (LOA), which you can download here.

You will receive two SMS notifications:  

 

  • The first SMS will confirm whether your request has been approved or rejected by your previous service provider. 
  • The second SMS will notify you once the process is complete, allowing you to use your M1 SIM card/eSIM with the ported number
