Internet access in Japan

You don’t buy a day pass, you add the day pass to your line. When you use cellular data or send a text or make any calls, you are charged $10 and all usage for the next 24 hours is covered and yes, that gives you access to the internet. That includes using your phone as a hotspot. Presuming your iPad has cellular service, it won’t roam so you’ll either need to use WiFi or your phone’s hotspot. Supposedly free WiFi is widely available in Japan so you may not even need to use the day pass.

Hi there @mkbilyk, we are happy to hear your response about the Internet in Japan.

Thank you @sandblaster for your input. Let's shed some light with more information about using your data while abroad:

Thank you.

I'm going to throw an additional warning at you, do not allow that iPad to roam in Japan. It is not covered by AT&T roaming agreements, you will be charged if that iPad connects to cellular data outside the USA, and the cost is considerable.
