Where are you
going?

Most flagships sold since 2020 do. Dial *#06# and look for an EID number. No EID means the hardware cannot take one. Carrier-locked handsets sometimes block it even when the hardware supports it, so run the device checker if you bought your phone on contract.

Yes. The eSIM is a second line carrying data only. Keep your home SIM active for calls and texts, set the eSIM as the data line, and switch roaming off on the home line so it cannot quietly bill you.

Almost always on first connection to a network abroad, not at purchase, which is why installing at home on wifi is safe. A few providers start validity at purchase and we flag those on the plan itself.

Some providers let you top up the same eSIM; others make you buy a fresh plan at full price. The top-up column tells you which one you are dealing with before you commit, and it is the single detail most people wish they had checked.

Rarely. Most run at full speed to a daily cap and then drop to roughly 1 Mbps, which is fine for maps and messaging and painful for video calls. We show the fair-use cap wherever the provider publishes one.

On the provider's own checkout. We hand you over with the code applied where we hold one. We never take your card details and we do not sell plans ourselves.

Usually, but not always, and it is the restriction providers are quietest about. Every plan on the site shows whether tethering is permitted, so check before you buy if you plan to share the connection with a laptop.

The catalogue is re-synced regularly and each page shows the date it was last read. Prices are the provider's list price at that moment, before any coupon, and providers do change them without notice.
