While there are several ways to connect to the Internet abroad, common means are through local SIM cards and WiFi hotspots. What are the differences?

Connection using SIM card is by replacing a SIM card used in Japan with the local SIM. Connection using WiFi hotspot is by WiFi Router that are usually available for rental at Japanese airports. You must return the WiFi Router once you are back in Japan.

In order to use the WiFi hotspot services, you must rent the equipment at the airport and it is likely that there is a deposit or insurance for the device. With SIM cards, however, if your smartphone is unlocked, you can simply dispose of the SIM card when you're done using it. It's much easier to handle than with WiFi rentals. Below are the advantages and disadvantages to using local SIM cards.

• Using WiFi hotospots requires a WiFi Router that needs to be carried around at all times, but you do not have to carry anything extra when you use a local SIM as all it takes is to replace the SIM card on your phone.
• You will only dispose of your SIM card after returning, but you will be obliged to return the SIM card to you, and you will be obliged to purchase extra insurance for any disabilities or loss while you are traveling.
• Although many rented WiFi have data usage restrictions, ANA/SIM cards can be used unlimited, so there is no risk of data overuse.
• Rented WiFi can share the Internet with multiple devices, but SIM cards and other devices can share the Internet with multiple devices by turning on personal hotspots.

The only disadvantage of using a local SIM is that your mobile phone must be unlocked. Unfortunately, you cannot use your phone with a local SIM if it has not been unlocked. But not to worry, it is easy to unlock your phone. Follow the below easy steps.
