Easy and Cheap Mobile Data in Japan
Choosing an eSIM for your next trip to Japan gives you the easiest way to get mobile data while traveling. In Japan, you can choose from nine different data packages ranging from 1 to 50 GB of data.
The large selection of data package sizes gives you plenty of options and the opportunity of finding just the right eSIM for your needs.
Cheaper than Physical Prepaid SIM Cards
Although Japan is often portrayed as a high-tech country, mobile telephony, and especially mobile data, is actually quite expensive. A popular provider of physical prepaid cards (SIM cards) is the local company Mobal.
Mobal offers several different prepaid SIM cards targeted at tourists. Below, I have compared two of their popular prepaid cards. The comparison clearly show that eSIMs from JetPac is the cheapest option for data roaming in Japan.
The prices are found on Mobal’s website and are very similar across competing prepaid SIM-card providers.
Comparison with Local Prepaid Card
The prepaid SIM cards from Modal starts at ¥4,730 (€29.4/ $30.3) for which you get 25 GB of data and a validity of 8 days. In comparison, the JetPac eSIM starts at just €1.0 ($1) for 1 GB of data and 7 days validity.
If you need more data and a longer duration, JetPac offers eSIM of up to 50 GB. The largest eSIM with 50 GB of data and validity of 30 days cost only €29.2 ($26). This is around half the price compared to the largest prepaid SIM card from Modal. Their largest eSIM comes with 50 GB and a validity of 31 days but for a price price of ¥7,920 (€49.3/ $50.7).
If you need more during your trip, you can ‘top-up’ with more data via the JetPac’s app.
Data Across Asia with a Regional eSIM
If you are going on a longer trip around Asia, such as a backpacking journey, it may be beneficial for you to choose a regional eSIM card. With a regional eSIM in Asia, you get mobile data in several Asian countries through one single eSIM. This saves you the hassle of buying multiple eSIMs and allows you to bring your data allowance with you across borders thus saving you money.
Enjoy Roaming in India and New Zealand
In Asia, you can choose between two different providers of regional eSIM cards for Asia: Airalo and Nomad. The two providers packages have clear differences in coverage, validity and price. So we recommend that you compare each provider to find the package that suits you.
Airalo give you coverage in most of Asia including China, Thailand and Vietnam. While Nomad also give you coverage in Oceania, as they also cover both Australia and New Zealand besides the 18 countries covered by Airalo.
