An eSIM is a SIM card you download instead of insert. Install at home calmly (5 minutes), do nothing during the trip — and once the plane lands, just turn airplane mode off. The data connects by itself.
Step 1: run our compatibility check with EXACTLY the phone that's traveling — mom's phone, not yours. Ten seconds, and it blocks the purchase if the model can't do eSIM. Step 2: buy the plan on the sofa at home, days before the trip. Don't buy at the airport in a rush — waiting has zero advantage, the plan only starts on arrival anyway.
After purchase you get a QR code. Open it on YOUR screen and scan with the traveler's phone: iPhone under Settings → Cellular → Add eSIM, Samsung under Settings → Connections → SIM manager. Sit side by side, on home wifi, no time pressure. If the QR misbehaves, the codes are in plain text on the order page for manual entry — our Samsung guide walks through it.
Step 4 is the nicest one: do nothing. The eSIM sits installed, resting. Step 5, when the plane reaches the gate: turn airplane mode off. The phone finds the local network by itself within a minute, and the WhatsApp messages start dropping in. Type 'landed!' in the family chat — that's the whole test.
If nothing happens after five minutes: restart the phone (fixes most things), and check Mobile data points at the travel eSIM. Still stuck — message us on WhatsApp, a human answers. And if it never activates, the guarantee applies: money back.
No. The regular SIM stays in and the number works as always. The eSIM just adds cheap data alongside.
Yes — send the QR over WhatsApp and they scan it there (shown on another screen, or use the manual codes). Wifi is enough for the install. But before departure is always easiest.
The smallest plan per country is the cheapest way in — and with the 'activated or refunded' guarantee the risk is zero. If it doesn't work, you don't pay.
