Would you like to use your smartphone in Japan?

You may be worried about getting charged too much for using your own smartphone when you're visiting Japan for sightseeing or business. Pre-paid SIM cards are a cheap and reasonable solution.

What is pre-paid SIM card?

Pre-paid SIM cards are automatically cancelled when you use up all the data, or when the contract period finishes.

The procedure for getting one is simple and does not require any initial contract costs. Also, you don't need to worry about any surcharges, as you pay everything before starting to use it. Those are the reasons why we recommend it to sightseeing and business travellers.

Please know that the SIM cards we're introducing here are only for data use, and do not allow phone calls. Phone call apps such as Skype are available however.

Do not forget to buy a Pre-paid SIM when you visit Japan!

If you travel with your country's SIM card, you would have to use roaming when a free WiFi connection is unavailable, for which you may have to pay surcharges and expensive bills.

The number of available WiFi hotspots is increasing, but you are still required to put in an effort to find them, and sign up to use them. Moreover, public WiFis are often not fast enough for regular tasks.

Pre-paid SIM cards allow you to cheaply get a fast internet connection without any complicated procedures or additional costs.

Do not fail to get a pre-paid SIM card when you visit Japan!
