Can someone help me figure out how to set up my rm520n-gl with visible. Every time I put the sim card in it says sim missing. I just got it from wireless haven and I set it up just like I did my em160r-gl and visible currently works on that. but not the rm520n-gl. I'm using a we826 first try I tried it in the usb3 adapter box that the rm520n-gl came in and figured maybe sim slot was messed up so ordered adapter and put it in the router to try that and it still says sim missing

Since your sim is working in both a phone and EM160R-GL, likely your modem is in the wrong mode or defective.
Try flashing it using the latest Quectel firmware, which should be easy to do since you have it in an external USB adapter.
Search on this forum for the factory reset command after flashing it.
