The eSIM plan activates immediately upon purchase. This means that as soon as you complete the payment, the plan is ready for use. It remains valid for 30 days from the purchase date and renews automatically each month for another 30-day cycle. If you are purchasing the plan in advance, please note that the activation will begin immediately—not on a future date. If the intention is not to start using the data plan right away, consider purchasing it closer to your team’s intended start date.
The Hotspot included in your Unlimited connection provides 10GB per day. This is sufficient data to work without any issues on any device.
