Will I get a phone number? How much data can I get in the Japan? Does it use 3G, 4G or 5G?

Researching into different packages and providers can be the difference between a great phone experience or a substandard one, but with so many telecom options available, it can often feel daunting! That’s why it is important to really dig into what each service offers. It may be that you only need a text or calling package and don’t require any data. Or, perhaps you are looking for multiple devices on the same plan. Always ensure that your understanding of the package is clear; most providers have separate packages for SMS/phone and data – don’t forget to include this detail when selecting your plan as many data plans do not come with an included phone number. Take the time to research thoroughly – now more than ever you’re spoilt for choice!
