Why roaming costs so much
Roaming bills your home network for using a foreign one, often at rates set long ago and rarely in your favor. The charges are per-megabyte and land after the fact, which is why a short trip can produce a shocking statement.
The fix: buy local data up front
An eSIM lets you buy a foreign network's data directly, at a price you see before you pay. There is no per-megabyte surprise and nothing to settle later. You top up once and draw down as you go.
You do not need a local SIM run
The old workaround was to land, find a SIM kiosk, queue, and register with your passport. An eSIM skips all of it: install before you fly, and it activates on arrival. No shop, no queue, no paperwork.
Keep your home number reachable
Leave your home SIM in the phone with roaming data switched off. Your number still receives calls and bank codes, while the eSIM carries all your data. On a dual-SIM phone, both run at once.
Pay without a card trail
Buying the eSIM with crypto means your trip is not tied to a card statement, and there is no ID to buy. One top-up covers a multi-country trip, and leftover balance stays for next time.
