The mobile industry continues to evolve at a rapid pace, but this book edition was written to be high level and evergreen. Much of it is still relevant in 2021.

Even so, a lot has changed since 2018 and we're now focused on maintaining the Mobile Internet Resource Center website and keeping our content up to date and we will no longer be keeping this book up to date. We consider this book retired.

This edition focuses on explaining the basics, helping you assess your needs, and laying the foundation for continuing research. To go further, we’ve provided links to accompanying guides on this website that are much easier to keep current with the latest options and go into more depth.

Most of the basic guides are completely free, and some also contain more advanced and member-exclusive content that goes even further.

It has been 2 years since the last edition of this book was released - and a lot has changed. If you're still in your research phase, then we definitely recommend starting out with the 5th Edition.

However, the 5th Edition is also a brand new approach to the topic, focused more on the foundations of mobile internet. It does not go into details on the specifics (such as products & plans) - and is more focused on what to keep an eye out for when shopping.

If you already have a solid foundation on your needs, understand the challenges of mobile internet and the basics of the options - then you might prefer to skip ahead to our more in-depth guides and product specific overviews.
