This book is a continuation—the second part—of the “Your Mobile Phone” manual. The structure of the publication remains the same: up-to-date answers to important questions related to the use of mobile phones. Experience has shown that this approach is the most successful. After all, mobile phones are constantly being improved and their capabilities are expanding, so many users may simply not know about them. All topics are presented in the book in an accessible and understandable form. In this publication you will learn how the mobile phone market is developing, how to buy a mobile phone on credit, how not to buy a “crude mobile phone”, how to use mobile banking, how Bluetooth technology works, how become a bluejacker, how to determine a person's character by reading the handset, etc. The book will be interesting and useful to all owners of mobile phones.
