It is well-known that mobile phone usage during lessons is, according to social standards, unwanted not only in several countries worldwide but also in Serbia. The Ministry of Education cannot handle effectively mobile phones, tablets, and other potential alternative educational methods or supplements. Thus, the easiest solution has become widespread; namely, to ban phones entirely out of classrooms. However, scratching the surface would not eliminate problems; it would just delay them given the fact that educational experts in the north treat this issue in a more liberal way. A good example would be Denmark that introduced the BYOT program (Bring Your Own Technology) and is determined to pin down that each school provide Wi-Fi coverage. This research aims to find out how teachers and learners treat this issue on the territory of Vojvodina. The authors attempt to justify their presuppositions according to which teachers feel certain scepticism about mobile phones in the classrooms, especially those teachers who are not owners of a smart phone. Data were collected through an on-line questionnaire with 455 young participants and 49 teachers from 9 municipalities in Vojvodina.
