Precaution Statement for SIM Card Purchase

  • Actual speeds vary depending on location and connection status.


It will stop and be deactivated. You will be given 3 days to top up another plan through our App to reactivate the SIM.

If you do not top up within 3 days, the SIM will be automatically terminated.

You can top up through our App (iOS , Android , and Web) with your credit card. The plan will be added in a few seconds once the transaction is successfully completed.

If you still have an active data plan on your SIM, the top-up plan will be queued and will automatically start when your current data plan ends. (You can see the queued data plan in Top Up History section in the app.)

For SIM cards bought through our site, the SIM will be already pre-activated and is ready to use when you receive it.

For SIM cards bought through other sites, there are cases where you have to set the activation date through our App. It's very simple step and all the information is on the manual you receive with the SIM.

Yes. For unused SIM, it will expire on the date written on the manual. So you have to start using it before that date.

For the SIM that has been already activated and used, it will expire 3 days after the active plan ends.
