We are experiencing an issue with a RUT950 device, where the SIM card is recognized but unable to register on the network. We have already updated the firmware to the latest available version (RUT9_R_00.07.04.1_WEBUI), switched the SIM card between SIM1 and SIM2, configured the APN according to the carrier's instructions, but nothing has worked. Until April 24th, it was working perfectly, but after a problem with the line, we had to transfer the line to a new SIM card. The SIM card was tested on a ZTE router and an iPhone 12, and it works perfectly on both. We also tested with a SIM card from another carrier, and it did not work on the RUT950. Finally, we reset the device to its factory settings, but it still didn't work, I don't know what else to do, does anyone have any ideas?
We have the same equipment on 9 other ships, and it works perfectly on all of them. The line used is from the Brazilian carrier "CLARO".
