It depends on the eSIM product. Some Gigago plans start counting down as soon as you install the eSIM (when you scan the QR code). Others start only when the eSIM first connects to a supported network in your destination. The description section in the product page will tell you which rule your plan follows.
For plans that start on installation, install your eSIM the day before you fly, or on your travel day while you still have Wi-Fi. For plans that start on activation, you can install a few days early. In both cases, make sure you have a stable Wi-Fi connection when you scan the QR code.
A common mistake is installing a plan that starts on installation a week before departure “to be ready”. That week is lost from your validity. If you’re not sure which rule your plan follows, check the product page or contact Gigago support before you scan the QR code.
Buy at least one day more than your trip. A Gigago day is counted until 11:59 PM Beijing time (GMT+8), so time zone differences can shorten your first or last day. For plans that start on installation, the day you install also counts.
For example, say you travel from May 1 to May 10 and your plan starts on installation. If you install on April 30, a 10-day plan runs out before your trip ends, so an 11-day or longer plan is the safer choice. With a plan that starts on activation, the countdown begins when you connect on arrival.
No, you can buy an eSIM plan whenever you want. The QR code stays valid for 30 days from the date you receive it, so you can buy early and install later.
For example, assume that you are going to travel Thailand from 1st to 10th May. If you buy a 10-day Thailand eSIM and activate your plan on the 1st May, it will last for your whole trip. But if you activate it on the 30th April, the plan will not cover your entire trip.
But if you buy a 10-day Thailand eSIM and your trip only last 5 days, you can set up your eSIM a few days before departure. Just make sure that you are connected to a stable wireless internet when installing and activating the eSIM.
