Don't see your SIM plan?
If you don't see the phone number of your SIM plan, check which email address did you use to set up the SIM plan.
If you set up your plan before the 15 Nov 2025, you may have used a different email address to set up the mobile account. Now that we have consolidated your mobile account into your Spacetalk App account, you can see all your details in the one place. If you had set up the mobile account under a different email address, we can transfer the details for you. For security purposes, we'll need you to contact us to verify that the mobile account is yours.
Do not try to re-activate your SIM if it was previously activated. You will get a 'SIM number invalid' error message.

You can select the same plan that you previously had.
Follow the prompts to complete the recharge.
