Choosing a plan
What to compare for Japan
Compare the total price, data allowance and validity period rather than looking at price alone. A cheaper plan may not be better value if it expires too early or includes too little data.
Network information also matters. Where available, review which mobile networks the eSIM can use in Japan, especially if your trip includes multiple areas.
Before purchasing, confirm that your phone supports eSIM and is unlocked for use with another mobile provider.
