How to set up an eSIM on Android (Pixel and Samsung)

Android eSIM support arrived with the Pixel 2 and went mainstream with the Galaxy S20, so almost any Android sold since 2020 (except some budget models) can do this. Menus differ slightly by maker; here are the two big ones plus the general path.

Before you start

• The phone must be carrier unlocked, and note that some carrier-sold Androids ship with eSIM disabled even when the hardware supports it; a quick search of your exact model plus “eSIM” settles it.
• Be on Wi-Fi with the provider’s QR code on another screen.

Pixel

1. Settings, Network and internet, SIMs, tap Add SIM (or the + next to SIMs).
2. Choose Download a SIM instead?, then scan the QR code.
3. Wait for the download, then label the line “Travel data”.

Samsung Galaxy

1. Settings, Connections, SIM manager, tap Add eSIM.
2. Choose Scan QR code from service provider and scan.
3. Confirm, wait for activation, and rename the line in SIM manager.

Other brands (Motorola, OnePlus, Xiaomi on global ROMs) follow the same shape: find SIM settings, look for “add” or “download” eSIM, scan.

The settings that stop surprise bills

In SIM manager or SIMs settings after installing:

• Calls and texts: home line. You keep your number for bank codes.
• Mobile data: travel eSIM. And turn OFF any “switch data automatically between SIMs” toggle; that feature can silently push data back to your home line at roaming rates.
• Data roaming: ON for the travel line only. On a travel eSIM this is normal and included in the price. Keep it OFF on your home SIM.

The Android-specific gotcha: APN

Androids ask for a manual APN more often than iPhones. If you land, have signal bars, and no data moves, open the travel line’s settings, find Access Point Names, and enter the APN from your provider’s install email exactly as written, then save and select it. This one step fixes a large share of “eSIM broken” complaints on Android.

When to install and activate

Install at home over Wi-Fi; leave the travel line off until you land. Validity starts at activation on nearly all plans, so nothing burns while you fly. Full timing logic is in my install-before-you-fly guide, and if anything misbehaves on arrival, run the not-working checklist top to bottom.

Quick answers

Dual SIM with my physical SIM? Yes, that is the normal setup: physical home SIM plus travel eSIM, both active, data pointed at the eSIM.

Can I move the eSIM to a new phone later? Usually not; most travel eSIMs are single-install. Newer Androids support eSIM transfer between your own devices, but treat a travel eSIM as tied to the phone you installed it on.

How big a plan do I need? Around 500 MB to 1 GB per day of normal use. The data sizing guide has the full table, and every destination page matches plan sizes to trip lengths with current prices.
