Frequently Asked Questions (FAQs)

Find helpful information to answer your questions

Can I use the eSIM on more than one device?

Each eSIM profile is tied to a single device once activated. If you need data on multiple devices (e.g., phone and tablet), you can either purchase separate eSIMs for each device or use the Personal Hotspot feature on your phone to share data with other devices.

Can I buy an eSIM for someone else as a gift?

Yes. Purchase the eSIM with your own details, then forward your order confirmation email - or share the "Install eSIM" link from it - with the recipient so they can install it on their own phone (the email contains the QR code and the manual SM-DP+ / activation codes). Make sure their device is eSIM-compatible first - installation usually cannot be reversed once completed.

Can I use the eSIM to make video calls?

Yes - apps like FaceTime, WhatsApp, Zoom, Google Meet, and Microsoft Teams all work over your eSIM data. Video calls use about 200-400 MB per hour depending on quality, so factor that into your plan choice if you make long calls regularly.

Is unlimited data really unlimited?

Unlimited plans provide unlimited data at high speed (4G/5G) up to a fair-use threshold defined per plan. Beyond that threshold, speeds may be reduced to 128 Kbps for the remainder of the validity period - still usable for messaging and basic browsing, but slower for streaming and video calls.

Can I install multiple eSIMs on the same phone?

Yes. Modern iPhones and Android devices support multiple eSIM profiles - typically 5 to 8 stored profiles, with 1 or 2 active simultaneously. You can install eSIMs for different countries and switch between them in settings without removing any.

Can I keep my WhatsApp number while using an eSIM?

Yes. Your WhatsApp number stays linked to your home SIM, so all your chats, contacts, and groups remain unchanged. WhatsApp uses data (not the SIM line directly) for messages and calls, so it works seamlessly over your eSIMno data.

When should I set up my eSIM?

A Wi-Fi connection is required to install your eSIM, so we recommend setting it up before you leave home. Activation can happen later, either right before departure or after you land at your destination - but the initial QR scan needs Wi-Fi.

Can I tether or use Personal Hotspot with my eSIM?

Yes. Your eSIMno plan supports tethering and Personal Hotspot at no extra charge. Activate the Personal Hotspot feature in your device settings and connect other devices as you would with any cellular plan. Data used while tethering counts toward your plan allowance.

Can I switch the eSIM to a different phone after activation?

Generally no. Once an eSIM is activated on a device, it's tied to that device. If you switch phones, you'll need to install a new eSIM. Some carriers offer eSIM transfer features, but eSIMno plans don't currently support transfer between devices.

How can I check my data usage?

Log in to the eSIMno Center on our website or mobile app to see your remaining data balance and usage history. You can also check usage in your phone's cellular data settings - most devices show data consumed per line.

What data plans are available for the Japan eSIM?

eSIMno provides various data plans ranging from 1 GB to unlimited data, with options from 7 days to 90 days of service. Plans also include regional and lifetime options for travelers who want flexibility across multiple destinations.

How long is the validity of the Japan eSIM plans?

The validity of eSIM plans varies from 7 days to 90 days depending on the plan you choose. Lifetime options are also available for travelers who don't want their data to expire after a fixed period.
