Recent Buy SXT LTE ("R11e-LTE") and working very well. First time user of RouterOS. I, update RouterOS(V6.48.1) and also update LTE firmware. Here, I getting trouble to do cell id locking. First, try it by "Modem Init-AT*Cell=<mode>,<NetworkMode>,<band>,<EARFCN>,<PCI>" but not working then found on Microtik Documentation under LTE mention that only work on Terminal process for this model. So, I try this using this CMD "/interface lte at-chat lte1 input="AT*Cell=2,3,,39150,255" and works. But after rebooting configuration resetting. I search on internet to fixing the problem not found any right way. How to fix this problem? It's a SXT LTE V2 version and It's have dual sim. Want to know about Dual Sim features?
