把 eSIM 设好，让长辈拿起手机就能用
出发前把配置都做完，落地之后要做的事越少越好。
快速解答
- Install the profile before the flight so only one step remains on arrival: switching it on.
- Write that step out in plain words on paper: finding instructions on a phone with no data is harder than it sounds.

常见问题
My mother has had the same phone for years — can it use an eSIM?+
Age alone does not answer it: it depends on the model, the OS version and whether the handset is carrier-locked. The fastest route is to check the model with our device checker, then confirm the lock status with the current provider, since only they can answer that. If the answer is no, other options remain — and knowing during planning is far better than finding out at the airport.
Should I let them do the steps themselves so they remember?+
Generally no, because the aim is not remembering an installation but being connected at the destination. Installation happens once and is never repeated, so memorising it is wasted effort. What they should practise is the part they will genuinely do on arrival: flipping the switch you labelled and opening the map app to confirm data is flowing. Two or three run-throughs at home is plenty.
If we install before the flight, does the plan's validity start counting straight away?+
It depends on the plan and the supplier. Some start counting when the device first attaches to a network at the destination, some from a date you choose in advance, and some from the moment the profile is enabled. Read the terms of the plan you bought before installing. The safest pattern is to install but leave the profile switched off until arrival, which is what this page recommends anyway.
If they tap the wrong thing en route, can it be undone?+
Most things can: switches can be flipped back and the data line can be swapped. Two things cannot easily be undone — deleting the eSIM profile, which usually cannot be reinstalled, and resetting network settings, which wipes the configuration. That is why the instruction card should say plainly not to do those two things and to get in touch instead.
How large a plan does an older traveller who barely uses data need?+
Actual use is usually lower than the family expects, but two things regularly cost more than anticipated: video calls home and automatic photo backup. Turn the backup off and agree that video calls happen on the accommodation's Wi-Fi, and the requirement drops sharply. Best is to put the real habits into our calculator and add headroom, because having spare is better than running short when topping up mid-trip would be awkward for this particular traveller.
If the trip covers several countries, does the plan have to change each time?+
Not necessarily. A regional plan covering every country on the route means no profile swapping at all, which suits a traveller who would rather not touch settings mid-journey. Check the covered-country list against the real itinerary, including transfer stops. If it does not cover everything, having both plans installed in advance still beats buying and installing something new on the road.
常见问题
What if the traveller is not comfortable with phones at all?+
The simplest arrangement is for a travelling companion to share by hotspot, keeping the eSIM as a backup.
Can I just activate it before the flight?+
Only if that plan starts on a chosen date. If it starts at first network attach, activating early wastes days.
