Honor 400 Pro eSIM

Does the Honor 400 Pro support eSIM?

Honor 400 Pro eSIM compatibility

Yes, the Honor 400 Pro supports eSIM—but only in global models. If you purchased your Honor 400 Pro outside China, Hong Kong, or Macao, your device includes eSIM functionality. Models sold in those three markets use dual physical nano-SIM slots instead and do not support eSIM.

You can confirm your variant by checking the box or visiting Honor's official spec page for your region. The Honor 400 Pro spec sheet will list whether your model includes eSIM support.

Dual SIM on the Honor 400 Pro

Global Honor 400 Pro models support dual SIM: one physical nano-SIM and one eSIM running simultaneously. You can take calls and texts on your primary line while using a travel eSIM for data abroad, or run two separate phone numbers at once. The device does not support dual eSIM—only one eSIM profile can be active alongside the physical SIM card.

The Honor 400 Pro storage type is non-expandable, so plan your apps and media accordingly. Color options for the Honor 400 Pro include Blue and other finishes depending on your region.

How to set up an eSIM on the Honor 400 Pro

Set up an eSIM in Settings

Setting up an eSIM on your Honor 400 Pro takes about 60 seconds. You'll need a QR code from your eSIM provider, sent by email or displayed in their app after purchase. Make sure you're connected to Wi-Fi before you start.

1. Open Settings and tap Mobile Network.
2. Tap SIM Management, then select Add eSIM or Add Mobile Plan.
3. Tap Scan QR code and point your camera at the QR code provided by your eSIM carrier.
4. Confirm the plan details and tap Add. The Honor 400 Pro will download and install the eSIM profile.
5. Label your lines—for example, "Home" for your physical SIM and "Travel" for the eSIM—so you can easily choose which line to use for calls, texts, and data.
6. Turn on the eSIM line by toggling it active in SIM Management, then set your data preferences.

What happens during eSIM installation

The Honor 400 Pro connects to your carrier's server and downloads the eSIM profile directly to the embedded chip. You'll see a confirmation message once activation is complete. If your eSIM doesn't activate immediately, restart the device and wait a few minutes for the network to register.

Using a travel eSIM on the Honor 400 Pro

A travel eSIM is the simplest way to get mobile data abroad without paying roaming fees on your home plan. You install a data-only eSIM before you fly, and it connects you the moment you land—no hunting for SIM card shops, no swapping tiny plastic cards at the airport.

Your Honor 400 Pro can store multiple eSIM profiles (though only one can be active at a time alongside your physical SIM). Install your travel eSIM while you're still at home and connected to Wi-Fi, then switch it on when you arrive. Your physical SIM stays in place, so you can still receive calls and two-factor authentication codes on your usual number.

To find a plan for your destination, browse eSIM plans by country or region. Most travel eSIMs deliver the QR code instantly after purchase, and many offer flexible data packages for a week, two weeks, or a month.

Staying connected without roaming charges

Once your travel eSIM is active on the Honor 400 Pro, set it as your default data line in Settings → Mobile Network → Default Mobile Data. You'll use the eSIM for internet, maps, and apps, while your home SIM handles voice calls and texts. Check your home carrier's rates if you plan to make calls abroad, or use Wi-Fi calling and messaging apps over your eSIM data connection.

Tips & troubleshooting

Turn on data roaming for the eSIM line

Even though you're using a local or regional eSIM, you may need to enable data roaming in your settings for the eSIM line to connect. Go to Settings → Mobile Network, select your eSIM, and toggle Data Roaming on. This does not trigger roaming charges on a travel eSIM—it simply allows the eSIM to access the local network.

Keep your home SIM active if you need to receive calls and SMS, including two-factor authentication codes from your bank or email provider. Just leave mobile data turned off for the home line to avoid accidental roaming fees.

Fix an eSIM that won't activate

If the QR code won't scan, check that your camera lens is clean and the lighting is good. You can also enter the activation code manually: tap Enter Code Manually in the eSIM setup screen and type in the SM-DP+ address and activation code from your provider.

If the eSIM installs but shows no signal, restart your Honor 400 Pro and wait a few minutes. Some networks take time to provision a new eSIM. Confirm that the eSIM line is toggled on in SIM Management and that you've selected it as the data line.
