💡Helpful Tips for eSIM

Device Requirements

Your phone must support eSIM technology and be fully carrier-unlocked.

Quick & Easy Setup

Buy online with no ID needed. eSIM is emailed within 3-5 minutes.

Seamless Usage

Scan the QR code to activate. Your physical SIM can remain in use.

Activation Timing

Plan starts when installed. We recommend installing 1 day before travel.

ℹ️ How to top up eSIM

Each eSIM plan supports up to 10–12 top-ups, depending on the specific plan.

Top-ups are cumulative: both the added data and extended validity period will be applied to the remaining balance of the currently active plan.

Example:
An active 1GB 7 Days plan topped up with the same plan will result in a total of 2GB valid for 14 days - reflecting the combined data and duration of both the original plan and the top-up.
