This plan does not yet support top-ups—but it’s something we’re working on behind the scenes. Choose enough data and validity for your trip. If your allowance runs out, purchase a new plan for your destination.
Account balance
You can still add funds to your BambooSIM account balance from Manage > Billing > Top up funds. Account balance funding is separate from adding data to an eSIM.
South Korea SKT call and SMS credit
South Korea SKT Unlimited data cannot be extended. Separate prepaid call/SMS credit can be added through SKRoaming or at an SK Telecom Roaming Desk. This does not add data or extend the eSIM plan.
