Rain sim has no signal.

I have been using rain mobile data since 2018, I had no issues until about a week ago when I had to change my device, My old device allowed for dual sim as does the current device, The problem I have now is the sim is activated but I have no signal, same sim I have always used. I reached out to the RAIN online live chat consultant twice, They suggested that I do APN settings following a step by step instructions they had sent, I sent them screenshots of the setting menu I had on my phone, and was advised to focus on profile as the rest should fall into place when the sim registers, so I followed the instructions, saved the settings and rebooted the device as advised.

After doing this on multiple occasions my RAIN sim still has no signal. I sincerely hope that there is a solution to this dilemma
