Why travellers buy an eSIM instead of roaming
Roaming in United States means paying your home carrier’s visitors’ rate — often £2–6 per MB outside the EU. A travel eSIM is a local-rate data plan you install before departure: scan, land, connected. Typical savings run 80–95% for the same usage, and there is nothing to queue for at the airport on arrival.
Your physical SIM stays where it is. Calls and texts keep landing on your number, WhatsApp keeps working, and all data traffic rides the eSIM instead of roaming. When you fly home, the eSIM simply idles until your next trip — most plans are valid for months.
Setup takes two minutes
Buy the plan → receive the QR by email → scan it in Settings → Mobile Data → Add eSIM → turn it on when you land (or set it to activate on arrival). No app stores, no top-up shops, no registration with a local carrier. Keep the QR email until the trip is over in case you reinstall your phone.
Frequently asked questions
How does an eSIM work in United States?
You buy a plan online, scan the QR code your provider sends, and the data plan installs on your phone. On landing in United States, it activates automatically — no shop, no swapping your physical SIM, no surprise roaming bill.
Will my phone support an eSIM?
iPhone XS/XR or newer, Samsung Galaxy S20 and most newer flagships, Google Pixel 3 and up, and most 2020+ cellular iPads support eSIM. If Settings → Mobile Data shows "Add eSIM", you're covered.
How much data do I need for United States?
Light use (maps, messaging, browsing): 3–5 GB covers a week. Heavy use (streaming, hotspot, video calls): 10–20 GB. Regional plans covering neighbouring countries too often cost barely more than a single-country plan.
Does an eSIM replace my WhatsApp number?
No — your physical SIM stays installed, so calls, texts and WhatsApp keep working on your home number while data runs on the eSIM. You avoid roaming charges because roaming data is what you're replacing.
