How to activate eSIM on Android depends on the manufacturer, but the safe order is consistent: check the phone, download the profile over Wi‑Fi, then make the travel plan the deliberate source of mobile data. Set it up before departure so you are not trying to read tiny menus on an airport curb.
Connect to Wi‑Fi and open Settings → Network & internet → SIMs on a Google Pixel, or Settings → Connections → SIM manager on a Samsung Galaxy. Tap Add SIM or Add eSIM, scan the provider QR code or use its app, label the line, and select it under Mobile data. Turn roaming on for that line only when the provider says it is required.
Check your Android phone first
Android is a family of devices, not one settings layout. A model name alone is not enough: eSIM support can vary by exact model, region, software build and carrier.
- Find eSIM support. Search Settings for eSIM, EID or SIM manager. If the phone shows an EID, that is a useful sign, but check the exact model's current specifications too.
- Check the carrier lock. A locked phone may accept only the original carrier's plans. Ask that carrier to confirm the unlock status before buying a travel plan.
- Use Wi‑Fi and power. The phone has to contact the provider to download the profile. Use a trusted connection and avoid captive portal Wi‑Fi when possible.
- Keep the QR code private. Put it on a laptop or second phone. Some codes are single-use, so do not forward them or repeatedly delete a partly installed plan.
- Read when validity begins. A plan may start at installation, at first network connection or at a provider-defined event. That one sentence changes the best time to install.
Pixel, Samsung and other Android paths
| Phone family | Typical route | What to look for |
|---|---|---|
| Google Pixel | Settings → Network & internet → SIMs → Add SIM → Set up an eSIM | Continue to the QR scanner or provider app. |
| Samsung Galaxy | Settings → Connections → SIM manager → Add eSIM | Choose Scan QR code or enter activation details. |
| Other Android | Settings search → eSIM, Add SIM or SIM manager | Names depend on the manufacturer, Android version and carrier. |
The labels above are a route map, not a guarantee for every release. If your phone shows Mobile Network instead of Network & internet, follow the closest SIM option and keep the provider instructions open.
How to activate eSIM on Android step by step
Open the plan menu over Wi‑Fi
Join stable Wi‑Fi, charge the phone and temporarily close VPNs or captive portal pages that could interrupt the download.
Open Add SIM or Add eSIM
Use the Pixel, Samsung or Settings-search path above. If the option is absent, verify the exact model before troubleshooting the QR code.
Scan the provider QR code
Choose the QR option and hold the camera over the complete code on a second screen. Confirm the plan name shown by Android before downloading it.
Let the profile download
Keep Wi‑Fi connected until Android says the eSIM has been added. A downloaded profile may still wait for the destination network before it provides service.
Label and choose the line
Name it Travel or the destination, then set it as the SIM for Mobile data or Preferred SIMs → Mobile data. Disable automatic switching while you verify the setup.
Apply the roaming instruction
Turn Data roaming on for the travel line only if the provider requires it. Keep roaming off on your home SIM if your carrier charges for international use.
QR code and manual activation
A QR code is the most common activation route, but it is only one delivery format. Raise the brightness on the second screen, keep the code flat and fully visible, and avoid photographing or sharing it in public.
If there is no QR code, look for a provider app or a manual entry choice such as Enter code or Enter activation details. The provider may supply an SM-DP+ address and an activation code. Copy those values exactly, including punctuation and capitalization; Android cannot infer missing values from the phone number, and a code from a different plan will not work.
Choose the correct data SIM
Dual-SIM phones make it easy to install a plan and still send data through the wrong line. After the profile appears, check the selector rather than assuming Android picked the newest SIM.
- Pixel: open Settings → Network & internet → SIMs, turn on the travel eSIM and select it under Mobile data.
- Samsung: open Settings → Connections → SIM manager, then set the travel eSIM under Preferred SIMs for mobile data.
- Home SIM: keep it for calls or SMS only if you need it, and turn its roaming or mobile data off when charges are a concern.
- Automatic data switching: disable it until you can identify which line supplied a test page. It prevents a weak travel signal from silently falling back to the home plan.
At the destination, wait for the eSIM to register, then toggle Airplane Mode once. If the provider lists a network selection or APN value, follow that exact instruction; do not copy APN settings from a random tutorial.
Common Android activation errors
Add eSIM is missing: check the exact model, regional variant, Android updates and carrier lock. Not every phone in a product family supports eSIM.
The QR code will not scan: use a second screen, raise its brightness, clean the camera lens and keep the full square in frame. If the code is already used, contact the provider instead of deleting the profile repeatedly.
The profile downloaded but there is no service: turn the travel line on, select it for data, check plan coverage and apply the provider's roaming instruction. Toggle Airplane Mode or restart once.
Mobile data works on the home SIM: revisit Mobile data or Preferred SIMs and turn off automatic switching. Our broader eSIM not working troubleshooting guide covers the next diagnostic checks.
Calls stopped working: data-only travel eSIMs usually do not replace your normal phone number. Keep the home line enabled for voice if needed, while reviewing its roaming fees.
