How do I add more data to my SIM card?
You can purchase additional data using our app (available on iOS, Android, and Web).
Once you've made a successful payment, the additional data will be allocated to your SIM almost instantly.
If you have an active data plan, the purchased data will be queued. It will be automatically activated when your existing plan expires.
