Your eSIM plan activates immediately upon purchase. This means that as soon as you complete your payment, your plan is ready for use. For example, if you purchase your subscription plan on the 1st of the month, it will be active from that day and remain valid for a full 30 days. When your subscription renews for the next month, it will automatically activate for another 30-day cycle. If you are purchasing your plan in advance, please note that the activation will begin immediately—not on a future date. If you do not intend to use your plan right away, consider purchasing it closer to your intended start date.
