Nothing special is required for the profile itself, but do handle your existing operator: switch data roaming off on the home SIM so nothing bills you while the eSIM carries your data. Registration rules attach to local numbers, and a data-only plan usually issues none.

Mostly it does, though not always instantly. At a crossing where both countries' signals overlap, the phone can hold the old tower for several minutes; one airplane-mode toggle forces a new search and usually settles it. If the next country is not on the covered list there is no warning at all — the data simply stops.

As a rule, no. Many plans start counting from the profile's first connection, so leaving it on can begin the validity while you are still in transit. Install it, but keep that profile's data roaming off until you are actually at the destination.

Give it about fifteen minutes first — registering on a new network takes time. Then toggle airplane mode once, confirm the right profile is enabled, confirm its data roaming is on, and try picking a network manually. If it still will not attach, message us with the handset model, the OS version and the order number.

Usually not. Travel plans are priced for short windows and generally cost more per gigabyte than a local monthly plan, and you go without the local number many in-country services use to verify you. The practical route is the eSIM for the first week while you settle accommodation and paperwork, then a local SIM — keeping the eSIM profile on the phone as a fallback.
