Question

Why is a subscription required for Pawfit-S and Pawfit 2?

Answer

All Pawfit models use mobile phone network to send over the tracking information and receive commands. Pawfit-S and Pawfit 2 have an embedded SIM card to do that. As the SIM card is non-removable, a small subscription fee is necessary to cover the data usage.
