Things to consider before choosing an eSIM for travel in Japan
No matter why you’re visiting Japan – be it for adventure, work, or anything in between – choosing the right eSIM is key to staying connected. Here’s what to keep in mind when selecting the best eSIM for Japan:
- Compatibility. Ensure your device supports eSIM technology before purchasing. While many smartphones, tablets, and even wearables now support eSIMs, not all models (and not everywhere) do. Check your device’s specifications to avoid activation issues.
- Coverage. Verify that the eSIM provider offers strong coverage in the specific areas you’ll visit. Some providers also provide regional plans covering multiple countries, such as Japan and Korea, or broader Asia-wide options.
- Call support. While many eSIMs are data-only, some provide a phone number for making and receiving calls or SMS. Be sure to check if the eSIM you choose includes full call and SMS functionality if you need it.
- Amount of data. eSIM providers typically offer fixed data plans, but some allow pay-as-you-go options. If you opt for a fixed plan, check if the provider enables top-ups so you can add more data if needed.
- Travel destination. Ensure your eSIM has strong coverage in all the locations you plan to visit, whether major cities like Tokyo and Osaka or rural areas. Some providers may have weaker signals in remote regions, so check coverage maps before purchasing.
- Travel duration. eSIMs come with varying validity periods, starting from activation. Check if your plan lasts for your entire trip to avoid losing connectivity before your journey ends.
- Tethering functionality. If you plan to share your data with other devices, your eSIM should support mobile hotspot functionality, and not all of them do. This is especially useful for connecting a laptop or tablet while on the go.
- Price. Compare eSIM plans to find the best value for your needs. Look out for hidden fees, such as activation charges or extra costs for calls and SMS, to avoid unexpected expenses.
