PAYG 4G sim only works once a day

[Catwithahat]

4g PAYG sim in camera only connects between midnight and 6am daily then won't connect again til next day. Only connects as 3g. It has data and power and has been hard reset and sim re installed multiple times

Other camera 8 meters away with PAYG o2 sim connects all day every day at 4g. My contract sim in phone gets 4g and data at every location of cameras and there is full 4g mobile broadband shown on network checker

In fairness that sounds like a faulty camera that has a timer set so that it will only connect between midnight and 6am. 

As there is nothing on o2 that would restrict it. 

Have your reached out ot the Manufacturer of the camera??

Try swapping sims between cameras and see if the issue follows sim or stays with camera.
