Benefits of using Holafly in Japan

Holafly offers several benefits like unlimited data, no roaming charges, and instant activation. You can keep your physical SIM card or your personal eSIM, and you could just switch to your eSIM while traveling around Japan to enjoy uninterrupted access to the internet.

You can enjoy unlimited internet access without worrying about needing a top-up or reaching data limits. This allows you to avoid roaming charges, meaning fees are consistent and reasonable. The eSIM setup is easy to navigate with a QR code, meaning that you don’t need to wait for a physical SIM card to arrive in the mail.

Holafly offers up to 500MB of data to share via Hotspot daily, meaning you can easily share your connection with others. If your travel plans change or you’re having issues with compatibility with your phone, Holafly gives you 6 months to request a refund. After this period, the Customer Support Team will be on hand to troubleshoot your issue if they cannot provide a refund.

Holafly coverage in Japan

Holafly Japan coverage provides a fast and stable internet connection in many tourist destinations in the country, including Tokyo, Kyoto, Osaka, Hiroshima, Kanto, and Nagasaki. eSIM Japan reports that the network you’ll connect to, KDDI, has nationwide coverage for over 98% of the country. 

Ensure that data roaming is turned on in your mobile settings to get the best coverage. No extra charges will be incurred once the Holafly eSIM has been set up and activated.

Holafly speed in Japan

Holafly Japan network provides maximum speed coverage across 3G, 4G, LTE, and 5G rates. However, some areas may have limited coverage, decreasing the connection speed, which can depend on the local service provider. 

Holafly estimates that download speeds are between 20 Mbps and 100+ Mbps globally, but this can differ by country and locality. Ping tends to be around 30-60 ms, fluctuating depending on the region and network conditions.

Internet speed may be reduced in rare cases due to the international measure of Fair Usage Policy. This ensures that all users enjoy an optimal connection. The reduction can only be applied for one day and will be lifted by the next day to your original plan speed.

How to use Holafly in Japan

Using Holafly in Japan is a simple procedure that involves installing the eSIM before your trip and activating it once you arrive in the country. This can be done with a QR code that you can scan and will be available to activate in Japan.

Here’s how to set it up and activate it in more detail:

  1. Check compatibility: Make sure your phone is compatible with eSIM technology. You can check this on the Holafly website.
  2. Purchase: Buy your eSIM for Japan on the website or from a partner like JapanTravel.
  3. Installation: You’ll get a QR code or activation code in your email
  4. Scan QR code: Use your phone to scan the QR code or enter the activation code manually to install the eSIM.
  5. Rename eSIM: If your phone has multiple eSIM profiles, rename the eSIM to easily identify it from your phone settings and find it once you arrive in Japan.
  6. Activate the eSIM: Once you’ve reached Japan, activate the eSIM and enable data roaming to use your active data plan and connect to the internet.

What to do if Holafly is not working in Japan

If your Holafly Japan eSIM isn’t working, you can try to fix the issue by checking your data roaming settings and ensuring that your eSIM has been correctly activated. 

Check that you’re in an area with good coverage and try restarting your phone. If the issue continues, you may need to reinstall the eSIM or check your current software update.

Take a look at our detailed troubleshooting advice:

  1. Data roaming: Ensure your data roaming settings are enabled so your Holafly eSIM works correctly. You can find this on iPhone under “Settings” under “Mobile/Cellular Service.” Navigate to the correct eSIM and tap “Data Roaming.” You can find this for Android under “Settings” in “Network & Internet.” Then, pick the correct eSIM and look for “Data Roaming” enabled.
  2. eSIM activation: Make sure that your Holafly eSIM is activated in the Holafly app or in the phone settings. You can check this in the “My eSIM” section of the app and the “Purchased” category.
  3. Signal and coverage: Check that you’re in an area with good cell service and try moving location to see if a stronger signal resolves your problem.
  4. Restart your phone: Sometimes a restart can help fix minor software glitches, so it’s worth turning your phone off and back on again.
  5. Reinstall the eSIM: If the problem continues, you should reinstall your eSIM. Locate the Holafly eSIM profile in “Settings” under “Network” or “Mobile Data” and remove it. Then, find the QR code you were provided and scan it to reinstall the eSIM.
  6. Update phone software: If your system software isn’t current, it can cause issues with eSIM functionality. Check for updates and install any available updates in your phone’s settings.
  7. Select a network manually: Your phone may not automatically connect to the best network available. You can turn this setting off by navigating to “Settings” and selecting “Mobile/Cellular Service” and tapping “Holafly eSIM,” followed by turning off “Automatic” and then selecting a network.
  8. Airplane mode: Turning airplane mode on for 30 seconds, then turning it off, can help to reset the cellular connection.

Is it better to choose a Holafly eSIM or a local Japan SIM?

You may be wondering if a local Japanese SIM is a better choice over an international eSIM like Holafly. If you’re staying for a short time or a couple of weeks, Holafly eSIM provides a convenient option. For longer-term stays, a local Japanese SIM may be more beneficial. 

Here are the pros and cons for each:

  • Holafly eSIM pros: You don’t need to buy a physical SIM once you arrive, and it can be activated instantly with no roaming fees. There’s flexibility in choosing the package that suits you best for your trip, while you can enjoy unlimited data on all plans.
  • Holafly eSIM cons: You won’t have a local phone number, so you can’t make or receive calls in the region directly on your phone. Some users may experience slightly slower speeds compared to a local SIM. Holafly does offer a daily Hotspot allowance, but it may not be as much as a local SIM. Further, you’ll need an eSIM-compatible device, which may not work for older phones.
  • Local Japan SIM pros: You’ll have a phone number where you can receive calls and texts locally. This can work out better cost-wise if you plan to stay in the country for a long time. Many providers offer free incoming calls and texts with unlimited data under stable conditions.
  • Local Japan SIM cons: More modern phones don’t have a physical SIM card slot, and you may need a physical SIM card to use a regional plan. This means there’s a risk of losing or damaging the SIM, particularly if you have to switch between SIM cards during your stay.
