In less than 15 years, the mobile phone has become an essential part of our daily lives. It is no longer a luxury item and has become one of the most commonly used daily consumer goods throughout the world. Despite its growing significance, there is still a lack of research work in many countries in this field. This study aims to make an approximation of the M-shopper profile and identify the variables influencing purchase behaviour. The methodology used to achieve these objectives is based on 7 focus groups and the analytical techniques of Chi-Square and logistic regression. Analysis of the results obtained from a representative sample of 2,104 Spanish Internet users shows that the M-commerce decision can be predicted according to consumer age, social class and behaviour patterns as user of non-store shopping channels.
