As you pack your bags and prepare for a new culture, one crucial detail can make your arrival infinitely smoother: instant, reliable internet access. Forget fumbling with airport WiFi or stressing about finding a SIM card store. With a Yoho Mobile eSIM, you can land in Tokyo, Osaka, or anywhere in between, already connected.

Why an eSIM is a Game-Changer for ALTs and JET Participants

Relocating to a new country comes with a long to-do list. Setting up a bank account, finding your way to your new apartment, and connecting with colleagues and family back home all depend on having a working phone. This is where traditional options fall short.

  • Airport SIMs: Often overpriced with limited data options.
  • Local Carrier Contracts: Can be a bureaucratic nightmare for newcomers, often requiring a residence card, Japanese bank account, and a long-term commitment you might not be ready for.
  • Roaming with Your Home Carrier: Incredibly expensive for a long-term stay and not a sustainable solution.

An eSIM (embedded SIM) is a digital SIM card that lets you activate a cellular plan without a physical card. For a long-term stay in Japan, the benefits are clear: you can set it all up before you even leave home.

This means you can step off the plane, activate your data, and immediately use Google Maps to navigate to your new home, message your supervisor, or video call your family to let them know you’ve arrived safely. It’s the ultimate tool for a stress-free start to your expat life in Japan.

Frequently Asked Questions (FAQ)

What are the best data plans for ALTs in Japan?

The best plan depends on your usage. We recommend starting with a larger data package for your first month (e.g., 20-30GB) to handle navigation, video calls, and setting up your new life. After you get settled and have home WiFi, you can switch to a smaller, more affordable monthly plan. Yoho Mobile’s flexible options allow you to adjust as you go.

Can I use Yoho Mobile’s eSIM alongside a Japanese SIM card?

Absolutely! This is a major advantage of dual SIM phones. You can use the Yoho Mobile eSIM for data, which is often cheaper and more flexible, while using a local Japanese SIM for a local phone number if your school or landlord requires one. This gives you the best of both worlds.

How do I top up my data if I need more during my stay?

Topping up is simple. You can purchase additional data directly through the Yoho Mobile app or website at any time. The new data package activates immediately, so you won’t experience any downtime. Please note that we currently support manual top-ups.

Is a Yoho Mobile eSIM better than getting a pocket WiFi in Japan?

For an individual teacher, an eSIM is generally more convenient and cost-effective. You don’t have to carry and charge a separate device, worry about it getting lost, or deal with return procedures. An eSIM integrates directly into your phone, providing a much simpler experience for your long-term stay.
