Hello. Yes, it needs the subscription otherwise it doesn't work. Kind regards

You don't have to buy a SIM card, there is already a SIM inside. The tracker therefore works independently of the network and should therefore also work with Swisscom.

This must be bought separately. It is important that you buy one that releases automatically if your cat gets stuck somewhere (happened 3x with mine!), otherwise it could be life-threatening. But I can recommend GPS 100%, it's worth it!

Yes, that's no problem! Anything else would be grossly negligent;)

I am not sure. It is better to ask the Tractive team.

That only works with a subscription. But it is very cheap.

Just over 2 days, without live tracking. In the beginning, you are tempted to track the cat live - out of wonder. With pure recording mode, the battery lasts over 2 days.

If you hear very well and the cat is not underground. But the GPS is really very accurate - if the reception is there. If the cat is somewhere in the house, the tracking doesn't work for me. Nevertheless, I wouldn't want to do without the device. My cat disappeared for 4 days and I only got him back through a huge portion of luck. Since I've had the tracker, I feel safe - and that's not meant to be surreptitious advertising. The battery should last longer, always log off after a location and recharge every night.

With the Tractive GPS Tracker for cats with activity tracking, you can buy a spare battery and change it so that the tracker can always be in operation.

Yes, according to the manufacturer, a subscription is necessary (4.80CHF/month per tracker).

Yes, the tracker can also be used together with a door opener tag, that is no problem at all. You can also read more about this in our Help Centre: https://help.tractive.com/hc/de/articles/360010922600?query=magnet
