While preparing for a trip to Japan last December, I decided to find out about the mobile phone service there. Getting a local number turned out to be a very complicated task: tons of formalities and, of course, a wait that could last for months. This didn't suit me at all, and at first I was even upset. But luckily, in the article What Japanese phone numbers look like? https://www.mobal.com/blog/living-in-japan/japan-phone-number/ , I found information about Mobal. They offer SIM cards and eSIMs with fast activation. It was incredibly convenient—all my communication issues were resolved immediately, and I could travel without unnecessary stress. I'm glad.
