GSM Connection and subscription
The robot communicates via GSM connection. The robot comes with a pre-installed sim card. The subscription is prepaid for 5 years starting from the date of purchase. When this time expires you will be offered to pay an annual cost of 20 euros / year. This payment is easily made in the app.
If you choose to not renew the subscription, the mower will still operate as normal with the settings you have made since before. However, you will lose the possibility to change settings or to use the app specific features such as the GPS tracking. You will neither receive new mower software updates.
