How do I know if my iPhone is eSIM compatible?

See “eSIM compatible devices”.

Should I install eSIM before travel?

Special Tip: Don't set up your eSIM too early.

Each eSIM data plan has a limited number of days of service, so don't start installing and activating too early, or the billing will start counting down before the trip begins.

Best practice is to set up your data plan on the day of your travel.

Of course, there are 2 specific installation time points, one option is before you travel and leave, when you are still at home, and the second option is once you arrive at the destination airport, but it should be noted that you need a stable Wi- Fi connection is required to complete the eSIM installation process.

You may prefer to set up the eSIM earlier than this so you're not in such a rush. But remember, once you set up your eSIM, you can't pause your plan, so the expiration date will start counting down.

In addition, pay attention to the precise calculation method of service days, The activation date is the first day and expires at 24:00 on the last day. The date and time above refer to Hong Kong Time (UTC+8).

For example, if you have a 1-day serice days eSIM card, and you are currently in London, UK, and it is 13:00 London time, if you choose to activate immediately, the actual calculation start time is 21:00 Hong Kong time, and the actual validity period is only 3 hours.
