Kyocera Digno Sx3 eSIM

Does the Kyocera Digno Sx3 support eSIM?

Kyocera Digno Sx3 eSIM compatibility

Yes, the Kyocera Digno Sx3 supports eSIM. This feature is available on models sold through au (KDDI) in Japan. If you purchased your Digno Sx3 directly from au or KDDI, your device includes eSIM capability alongside the physical SIM slot.

The Digno Sx3 is a Japan-market smartphone, and eSIM support is tied to the au/KDDI carrier version. If you bought an unlocked unit from another source or a different Japanese carrier, confirm eSIM availability in your device settings before purchasing an eSIM plan—some regional or carrier-specific variants may differ in their feature set.

Dual-SIM functionality on the Digno Sx3

The Kyocera Digno Sx3 offers dual-SIM capability by pairing one physical nano-SIM card with one eSIM profile. You can keep your primary au line active on the physical slot and add a travel eSIM for data when you're abroad, or use the eSIM for a secondary domestic line. The device does not support multiple eSIM profiles active simultaneously—you can store several eSIM profiles but only one can be enabled at a time alongside your physical SIM.

How to set up an eSIM on the Kyocera Digno Sx3

Kyocera Digno Sx3 eSIM activation steps

Setting up an eSIM on your Digno Sx3 takes about 60 seconds once you have your QR code from your eSIM provider. Make sure you're connected to Wi-Fi before you begin, since the device needs to download the eSIM profile during activation.

Open Settings on your Kyocera Digno Sx3.
Tap Network & Internet (or 接続 on Japanese-language devices), then select Mobile network or SIM cards.
Tap Add mobile plan, Add carrier, or the + icon to start adding an eSIM.
Choose Scan QR code when prompted. Point your camera at the QR code provided by your eSIM carrier.
The Digno Sx3 will download and install the eSIM profile. This usually takes 30–60 seconds.
Once installed, give your new eSIM line a label—like "Travel" or "Data"—so you can tell it apart from your au physical SIM.
Enable the eSIM line and set it as your default for mobile data if you want to use it for internet access.

Manual entry if the QR code won't scan

If your camera struggles with the QR code, most eSIM providers also offer manual activation. Look for an option like Enter details manually in the add-mobile-plan screen, then type in the SM-DP+ address and activation code supplied by your carrier. The steps are otherwise identical.

Using a travel eSIM on the Kyocera Digno Sx3

Stay connected abroad without roaming fees

A travel eSIM is an easy way to get mobile data when you leave Japan. Instead of paying au's international roaming rates or hunting for a physical SIM card at the airport, you install a data-only eSIM before your flight. Once you land, the eSIM connects to a local network and you have internet access immediately—no SIM-card swaps, no hunting for a store.

Install your travel eSIM while you're still at home and connected to Wi-Fi. The profile sits dormant on your Digno Sx3 until you arrive in your destination country and turn it on. Your au physical SIM stays in place, so you can still receive calls and text messages (though standard roaming charges apply for voice). For data, switch to the travel eSIM line and avoid roaming fees altogether.

Browse and compare eSIM plans

You'll find regional and global eSIM plans covering dozens of countries. Browse eSIM plans to compare data allowances and coverage, then buy and install the profile that matches your itinerary. Most travel eSIMs activate automatically when you connect to a supported network, so there's no need to configure APN settings or call customer service.

Tips & troubleshooting

Turn on data roaming for your eSIM line

Even though you're using a local travel eSIM, your Digno Sx3 often treats it as "roaming" because the profile isn't from your home carrier. Go to Settings → Network & Internet → Mobile network, select your eSIM line, and toggle Data roaming on. Without this, the eSIM may not connect even when the profile is active.

Keep your au SIM active for calls and two-factor codes

Leave your physical au SIM enabled while traveling so you can receive voice calls and SMS messages for banking or two-factor authentication. Set the eSIM as your default for mobile data, and the au line as your default for calls and SMS. This way you stay reachable on your usual number without paying data-roaming fees.

What to do if the QR code won't scan

If the camera won't focus or recognize the QR code, increase your screen brightness (if you're scanning from another phone or laptop) or print the QR code on paper. Alternatively, use the manual-entry option and type the SM-DP+ address and activation code. You can also get eSIM setup help if the profile still won't install.

Check compatibility for other devices

If you're upgrading or considering a second phone, you can check another device's eSIM compatibility to confirm support before you buy. Not all Japanese-market smartphones include eSIM, so it's worth verifying in advance.

Digno Sx3 eSIM FAQ

Everything travellers ask about using an eSIM on the Digno Sx3.

Does the Kyocera Digno Sx3 have eSIM?

Yes, the Kyocera Digno Sx3 supports eSIM on models sold by au (KDDI) in Japan. You can use one eSIM profile and one physical nano-SIM at the same time, making it a dual-SIM device. Confirm your specific unit includes eSIM by checking Settings → Network & Internet → Mobile network for an "Add mobile plan" or similar option.

Can I use two eSIMs at once on the Digno Sx3?

No, the Kyocera Digno Sx3 supports one active eSIM and one physical SIM simultaneously. You can store multiple eSIM profiles on the device, but only one eSIM can be turned on at any given time. To switch between eSIM profiles, disable the current one in mobile-network settings and enable the profile you want to use.

Is the Digno Sx3 eSIM free to use?

The eSIM technology itself is built into your Kyocera Digno Sx3 at no extra cost, but you'll pay for the mobile plan or data package you activate. Travel eSIM providers and carriers charge for their service plans, not for the eSIM feature. Once you buy a plan, installation and profile management are free through your device settings.

Will a travel eSIM work if my Digno Sx3 is locked to au?

If your Kyocera Digno Sx3 is carrier-locked to au, you may not be able to use an eSIM from a different provider until you unlock the device. Contact au to request a SIM unlock—most carriers in Japan will unlock phones that are fully paid off. Once unlocked, you can install and use any compatible travel or international eSIM.

How do I remove an eSIM from my Kyocera Digno Sx3?

Open Settings, go to Network & Internet, tap Mobile network, and select the eSIM profile you want to delete. Choose "Erase" or "Delete SIM" to remove the profile permanently. Deleting an eSIM frees up space for a new profile, but you'll need a fresh QR code if you want to reinstall the same plan later—most eSIM QR codes work only once.
