Pocket Wifi VS SIM Cards | NINJA WiFi | Pocket WiFi rental Japan

Comparing the two reveals how much more convenient a router really is.
SIM cards can establish a connection with the internet. However, we recommend you use a WiFi router if you plan to visit various sightseeing locations and use the internet a lot while traveling around.

SIM cards are not easy to set up, especially for those not used to the system. Instead, use a router that only requires powering on and entering a password for instant connection. It is the easier connection, suitable for users of all ages.

Also, since you cannot use a SIM card with more than one device, it can be incovenient for anyone travelling with friends or family who also wish to use the internet.

And even those who still think a SIM card is better for them still risk losing their original SIM while they are using their new SIM in Japan.
