Hello Everyone,
I have a problem with SXT LTE kit v2. In general, the device works flawlessly, the connection is stable and fast, but... from time to time the Internet goes down, and the interface status says "no sim card inserted". I can reboot it etc, but it won't help. I have to take a ladder, go to the roof, remove power, remove sim card, insert sim card back in, attach power (ethernet) and it starts to work.
There's no obvious reason for that behavior: it can happen on sunny, hot day, or during cold & rainy weather. Sometimes it works for a month without a problem, sometimes a week. I can shake it, throw it, smash it with a hammer (okay, maybe without the last one ) - it will still work. And one it will loose the card again.
I think it has something to do with the poor sim card copper pads quality (they got rusty and re-inserting the card removes the rust from it), but is there anything I can do with it?
The problem is that the device is at my summer house and I'm here only during weekends, so if SXT will loose the sim card during a working-day - I'll lost monitoring (cameras, sensors, solar panels control etc.).
Any advise will be much appreciated
Thank you in advance,
Tom
