FIRST things first the router in question is a CELL C RTL31VW LTE-A made by ASKEY. I tried to use it with my rain sim card and for some reason it did not pick up the sim(router had been confirmed working with vodacom prior to this )and for what ever reason I decided I needed new firmware and stumbled across the “all we know about RTL30VW LTE-A” forum and I saw firmware and immediately started to flash ... long story short I only see now that the model differs and my router does not have support for sim under network anymore any help would be greatly appreciated(I need firmware for the RTL31VW or any tips on what I can try would also be GREAT maybe custom firmware from something opensource like openers.org )
