Vietnam is a rare country where you can use free wifi everywhere, from the airport, to restaurants, bars, even sidewalk stalls. But when traveling abroad, the first thing you must prepare in advance for your trip is a data sim, or portable wifi modem, because in most developed countries, there are not many locations with free wifi available. , and your trip may face many inconveniences without an Internet connection.

Today I will show you the easiest way to rent yourself a data sim or portable wifi modem at the most reasonable cost in Japan.

  1. eSIM data.

If you are traveling solo in Japan, and not using any other laptop or tablet besides your phone, then a data eSIM is all you need.

  • Advantages of eSIM data:
    – Easy to set up and use as soon as you arrive in Japan (just scan the QR code and you can use it immediately)
    – Can still be used in parallel with your main SIM without having to worry about the phone only having one SIM tray.
    – Cost savings
  • Disadvantages of Sim data:
    – Can only be used on a single device.

2. Pocket wifi (Handheld wifi modem)

If you travel to Japan in a group, with family, or on business trips with many wifi-connected devices, a Pocket wifi will be more suitable for you.

  • Advantages of pocket wifi:
    – Compact, can be easily put in pocket.
    – Can connect multiple devices at the same time (up to 10 devices)
    – Fast and stable wifi speed
    – Unlimited capacity
    – You can pick up your router at the airport, your hotel, or anywhere you want.

  • Practical experience of Pocket wifi in 7 days:

Pocket wifi was delivered just one day after registration.

Inside the package is a bag that includes:

– Pocket wifi

– 5000mAh power bank

– Type C cable and socket

– User manual

– Envelope for you to return Pocket wifi after the end of the rental contract.

Setup is also extremely simple, just hold the power button to turn on Pocket wifi, then find and connect to wifi according to the username and password pasted on the Router.

The average wifi speed fluctuates at 60-80 Mbps, watching YouTube or playing games without any problems.

Touch operations on the router are smooth, battery life can be used from morning to night before needing to be recharged. During my week of traveling, there was hardly a day when I needed to recharge the router, even though I connected quite a few devices at the same time.

After using up the lease term, I just need to put all the equipment I received in the enclosed envelope, seal it and stuff it into the mailbox near my house. Very easy to return.
