Best eSIM for Japan: Jetpac Global Review

Japan is one of those places that steals your heart, and also throws a few curveballs when you arrive if you’re not properly prepared.

Trust me, I know this all too well! On our very first trip to Japan, I thought I was super organised.

I’d purchased what I thought was the best eSIM for travel to Japan, loaded up my phone, and hopped off the plane feeling like a tech-savvy pro. Except… my eSIM failed to activate.

There we were at Narita Airport. No internet, no QR code for our airport transfer, and zero clue how to navigate the maze of train platforms without Google Maps.

Cue minor panic as we ran around looking for WiFi just to buy a new eSIM on the fly. It was not the smooth arrival I’d hoped for.

That first disaster was enough to make me realise that choosing the Best eSIM for Japan is way more important than I thought.

On our most recent trip back to Japan, we decided to do our homework properly.

After hearing so much good stuff about Jetpac, we activated their eSIM before we even left home and let me tell you, what a game-changer!

eSIM or Pocket WiFi Japan: What’s Better?

You might wonder whether eSIM or pocket WiFi Japan is the way to go.

After a few trips, my answer is always eSIM. A pocket WiFi is one more thing to charge and carry, and let’s be real, we already travel with enough cables and gadgets.

FAQ’s on using an eSIM in Japan

How Much Data Do You Actually Need?

Here’s a quick tip from our own experience.

Most tourists will burn through about 1 to 2 GB per day if they’re using Google Maps, uploading pics to Instagram, translating menus, and staying in touch on WhatsApp. Jetpac has affordable data packages that let you top up easily if you need more, so you’re never stuck.
