Your Nothing Phone 3 can run one physical nano-SIM and one eSIM simultaneously.

How to set up an eSIM on the Nothing Phone 3

Setting up an eSIM on your Nothing Phone 3 takes about 60 seconds. You'll need a QR code from your carrier or eSIM provider, a stable Wi-Fi connection, and access to your device settings.

Nothing Phone 3 eSIM activation steps

Connect your Nothing Phone 3 to Wi-Fi.
Open Settings and tap Network & internet.
Tap SIMs, then select Add SIM or the + icon.
Choose Download a SIM instead? or Add eSIM.
Scan the QR code provided by your carrier or eSIM provider using your camera.
Tap Download and wait while the eSIM profile installs—usually 30 to 60 seconds.
Label your eSIM line (e.g., "Travel" or "Work") so you can identify it easily.
Choose which SIM to use for mobile data, calls, and SMS in the SIM settings menu.

Set up an eSIM in Settings

Once your eSIM is installed, you'll see it listed under Settings > Network & internet > SIMs. You can toggle each line on or off, assign a default for data, and rename the lines. If you install a travel eSIM, you can switch your data line to the eSIM while keeping your home SIM active for calls and texts.

Using a travel eSIM on the Nothing Phone 3

A travel eSIM lets you get mobile data abroad without paying roaming fees from your home carrier. You keep your primary SIM active for incoming calls and two-factor authentication codes, while the eSIM handles data—maps, ride-sharing, messaging apps—at local rates.

Install your travel eSIM before you fly

Install your travel eSIM while you're still at home and connected to Wi-Fi. The profile sits dormant on your Nothing Phone 3 until you land and turn it on. Once you arrive, enable the eSIM line and select it as your data source in Settings. Your home number stays reachable for calls and SMS, so you won't miss important messages. You can browse eSIM plans for your destination and install the QR code in minutes.

Switch data between SIM lines

To use your travel eSIM for data, go to Settings > Network & internet > SIMs and tap Mobile data. Select your eSIM line. Your physical SIM remains active for voice and texts unless you disable it manually. This setup keeps you connected without juggling SIM cards or hunting for a local carrier at the airport.

Tips & troubleshooting

Most eSIM activations on the Nothing Phone 3 work on the first try, but a few settings can trip you up if they're not configured correctly.

Turn on data roaming for the eSIM line

After you activate your travel eSIM, go to Settings > Network & internet > SIMs, select your eSIM, and enable Roaming. Travel eSIMs require roaming to be on because the eSIM profile connects to a local network abroad. This is not the same as your home carrier's expensive roaming—your eSIM plan has its own data allowance and rates.

Fix an eSIM that won't activate

If your QR code won't scan, check that your camera lens is clean and the lighting is even. You can also enter the activation code manually: tap Enter code manually (or Need help?) and type the SM-DP+ address and activation code from your eSIM provider. Restart your Nothing Phone 3 after installation if the eSIM line doesn't appear immediately. If you're still stuck, eSIM setup help can walk you through carrier-specific issues.

Keep your home SIM for calls and 2FA

Leave your primary SIM enabled even when you're using an eSIM for data abroad. Banks, email providers, and authentication apps often send one-time codes to your home number, and you'll need that line active to receive them. Set your eSIM as the data line and your physical SIM for calls and SMS in the SIM settings menu.

Check another device's eSIM compatibility

If you're comparing phones or helping a family member choose a device, you can check another device's eSIM compatibility before you buy. Not every Android phone includes eSIM support, and some models limit it to specific regions or carriers. The Nothing Phone 3a and Nothing Phone 3a Pro both support eSIM, but always confirm the feature on the exact model and variant you're considering.
