What is an eSIM? How should I use it?

An eSIM ("embedded SIM") is a SIM card built into your phone as software. Instead of pushing a plastic chip into a tray, you install a profile — usually by scanning a QR code — and your phone can join a mobile network exactly as if a physical SIM were inside.

For travel, that changes everything: you can buy data for your destination before you fly, install it from your sofa, and land with a working connection — while your home SIM stays untouched in its slot.

Functionally they do the same job — identify you to a mobile network. The differences are practical:

• Delivery — an eSIM arrives as a QR code in seconds; a physical SIM needs a shop, a kiosk, or a courier.

• Space — most modern phones hold one physical SIM plus several eSIM profiles, so your home number keeps working alongside your travel data.

• Swapping — switching eSIM plans is a settings toggle, not a paperclip-and-tray operation at an airport bench.

• Loss-proof — there is nothing physical to lose, bend, or forget in a hotel drawer.

• Keep your home number active for calls, texts, and one-time codes from your bank — it stays in the physical slot while the eSIM carries your data.

• Buy before you fly and skip the arrivals-hall SIM hunt entirely.

• Prepaid means predictable — no surprise roaming bill at the end of the month.

• One phone, many trips — store profiles for different destinations and enable the one you need.

1. Pick a destination and plan on our plans page — data amount and validity are shown up front.

2. Check out — your eSIM is prepared right away; no shipping, nothing physical.

3. Install it from your dashboard by scanning the QR code (or entering the details manually). Do this on Wi-Fi before you travel — our installation guide walks through every step.

4. Land and connect — turn on the eSIM's data line and data roaming for that line, and you're online. For most plans, validity starts when the eSIM first connects at your destination.

5. Track usage in your dashboard, and top up if your trip runs long.

Yes. Your physical SIM (and its number) stays active for calls and texts — useful for banking codes and missed-delivery calls — while the Globeelink eSIM handles data. In your phone's settings you choose which line carries mobile data; keep data roaming off on your home line to avoid its roaming charges, and on for the travel eSIM.

Most phones released since about 2019 support eSIM, but carrier-locked devices and some regional models are the exception — check before you buy. Our compatible devices article shows the 60-second check, or use the device compatibility checker for a live answer for your exact model.
