- An LTE module is significantly expensive (10€?). - A carrier contract costs some money (some m2m contracts for very low bandwidth can go for around 1€/month)

- An LTE module is significantly expensive (10€?). - A carrier contract costs some money (some m2m contracts for very low bandwidth can go for around 1€/month). - It's extra design and management effort (antennas, contract management and such) - Maybe most importantly: It's rather easy to spot and people would ask uncomfortable questions.
