What is a Telwel eSIM for travel?

A Telwel eSIM is a virtual SIM card that allows you to use a prepaid local internet plan without the need for a physical SIM. No identification or passport is required to purchase—just a few clicks. The eSIM has no phone number and is intended exclusively for internet, messengers, social networks, and video calls.

Which devices are compatible with Telwel eSIM?

You can install Telwel eSIM on phones and tablets running iOS or Android that support eSIM technology. To check if your device supports eSIM, enter *#06# on your device—if you see an EID number, eSIM is supported. You can also check for «Install eSIM» or «Add eSIM» options in your device settings.

How do I receive my eSIM after purchase?

After purchase, your eSIM (QR code) will appear in your Telwel account on the website in the «Non-actived eSIM» section, and in the Telwel app for both Android and iOS under «My eSIM.» For iOS, installation takes just a tap on the «Setup eSIM» button—no QR code scanning is required.

How do I install and configure the eSIM?

Step-by-step instructions with screenshots are available in the «How to Use» section on our website. Simply select your device type and installation method (website or app). Key configuration steps are highlighted in red for your convenience.

When should I install my Telwel eSIM?

We recommend installing your eSIM just before your trip, while still in your home region, with a stable internet connection. You can also install it abroad, but if your connection is poor, postpone installation to a better time.

Does the Telwel eSIM plan include only internet?

Yes, only internet access is included—there is no phone number, and you cannot make standard calls or send/receive SMS.

How do I manage my balance and top up with Telwel eSIM?

You can view your remaining days and data volume in the app under «My eSIM» or in your account on the website under «Active eSIM.» Check your balance frequently. When the data or validity period ends, simply purchase a new eSIM with any required data amount.

Can I share internet using Telwel eSIM?

Yes, you can share your internet connection freely within the limits of your purchased data.

Will my Primary SIM card still work?

Yes, but make sure your mobile internet is set to use the eSIM to avoid roaming charges from your main operator. Alternatively, you can disable your Primary SIM for the duration of your trip. Device setup screenshots are available in «How to use» on the website.

Why is Telwel eSIM better than local SIM cards?

You get instant internet access upon arrival without removing your Primary SIM or searching for local stores, providing documents, or signing contracts. In some countries, buying a local SIM is difficult. Telwel’s internet prices are close to local operator rates

Are there any hidden fees or charges?

No, there are no subscription or hidden fees. Only the prepaid data amount is used—safe and straightforward.

When does the validity period of eSIM start?

The eSIM activates as soon as it connects to the local operator’s network.

Can I get a refund for my eSIM after purchase?

Unfortunately, no—eSIMs are non-refundable. If you encounter any issues with installation or activation, contact support via the website, the app, or hello@telwel.io . Our support team is available 24/7.

How long does it take to activate the eSIM after purchase?

Activation usually takes just a few minutes; in rare cases, up to 1 hour. Ensure a stable internet connection (from your Primary SIM or Wi-Fi) during activation.

What should I do if I see an “Activation failed” or “Invalid code” error?

In most cases, these messages are not critical. Check if the eSIM is present in your device’s settings. If unsure, contact customer support.

Can I reinstall the eSIM on the same device if it was deleted?

We recommend keeping your eSIM until the plan expires. If it is accidentally deleted, you can try scanning the same QR code again on the same device with a stable connection.

Traveling in Japan: Modern Streets, Ancient Temples, and Seamless Connectivity

Traveling in Japan means Tokyo’s ultra-modern streets, Kyoto’s ancient temples, Hokkaido’s snowy slopes, and Okinawa’s seaside coastline. With a Telwel eSIM, you can stay connected wherever you are, discovering new horizons on business trips, family vacations, and independent journeys.

Communicate, share your experiences, plan routes, and get to know the country more closely: mobile internet is available within partner-network coverage, allowing you to quickly open maps and tickets, use WhatsApp and other messaging apps, and avoid constantly searching for Wi-Fi.

What is an eSIM in Japan and how to activate it

An eSIM (embedded SIM) is a digital profile that is downloaded to your device’s built-in module and, depending on the plan, allows you to connect to the local networks of a selected operator — KDDI or SoftBank. In essence, it is a virtual SIM that works on your device and lets you avoid changing your physical plastic SIM card in a new country, while keeping the ability to use your usual phone number if your smartphone supports dual-line operation.

Before installation, check whether your phone is among the devices that support eSIM technology. After purchase, you receive an electronic profile that can be installed via a QR code on a compatible iPhone or Android device. To activate an eSIM in Japan, you need to complete the settings and connect to a supported network. The terms under which your plan starts depend on the selected package.

eSIM technology provides access to 4G and 5G networks where the relevant coverage and device support are available. You can also keep your home SIM card and use a travel eSIM plan for internet without enabling data roaming through your home operator.

How to buy an eSIM for Japan and connect to mobile internet

You can buy an eSIM for Japan in just a few minutes on the Telwel website. Before purchasing, review the available eSIM plans and choose the one that suits your route — whether it is Tokyo, Kyoto, Osaka, or a trip across the whole country. You will find genuinely competitive plans that let you use the internet within local-network coverage without unnecessary extra charges — for tourism, work, study, or short trips. This Japanese eSIM provides access to high-speed mobile internet, while connection stability depends on coverage and network congestion.

This format is especially convenient for those who want to get online immediately after landing and avoid buying Japanese SIM cards at the airport. You can install the profile before departure. To do this, connect to Wi-Fi, open your smartphone settings, select the option to add an eSIM, and scan the QR code received after purchase. Installing the profile takes just a few minutes, but instant network access is possible only if the plan’s activation terms are met. Upon arrival in your destination country, select the new line for mobile data and, if necessary, enable data roaming for it in your phone settings.

After purchase, you will receive instructions for quick activation on supported smartphones in your personal account and in the “My eSIMs” section of the convenient Telwel app. The “How to Use” section always offers clear screenshots and tips for popular device models. Once your eSIM is connected in Japan, you can use navigation, messaging apps, and other services that consume mobile data.

Before installing an eSIM, check your smartphone’s compatibility and make sure it is not carrier-locked. If the profile has already been installed, do not delete it unless necessary: reinstalling it using the same QR code may not be possible.

How to choose an eSIM plan for Japan

When choosing a plan, consider the length of your trip and your expected data usage. For maps, tickets, messaging, and searching for information, a small package may be enough — for example, 1 GB for a short period. If you plan to make video calls, watch videos, or work from a laptop, it is better to choose more data.

For a longer trip, consider packages with a validity period of up to 30 days, if they are available in the catalog. When choosing a plan with unlimited internet, check the terms of use separately: some offers include speed limitations after a certain amount of data has been used.

A travel eSIM for internet usually does not include a separate Japanese phone number. Calls and SMS over the mobile network are generally not available with such plans, but you can communicate through internet-based apps. If necessary, keep your primary SIM card for your usual number.

Keep track of your remaining days and gigabytes in real time: all plan information is displayed online in your personal account and app. Here, you can conveniently check your data usage and, if needed, quickly choose a new plan or purchase additional data packages — you decide how much connectivity you need. With a Telwel eSIM, you can also share internet with other devices — convenient for family, friends, and work.

Below, you will find useful instructions and answers to frequently asked questions: learn how connection works, which smartphones and tablets are compatible, how to pay and get mobile internet faster during your trip, and what to set in your phone settings. If you need help, our customer support team will guide you through the setup — stay connected while traveling across Japan.

Your introduction to Japan with a Telwel eSIM will be affordable, simple, and as comfortable as possible!
