Ridiculous

My Rain router was delivered on the 9th of January 2023. The device has been offline since the day of delivery. I was informed to reset the device and move it around the house. Still, I have no internet connection. One agent informed me that although the sim card is registered on my side, it is not registered on their side. She informed me to wait for 24 hours. 24 hours have passed, and still, I have no network connection. I am really beginning to think that some of the reviewers are right, My Rain is a ****. I am very disappointed. I am strongly considering requesting cancellation.
