So I am pretty stupid with advanced cat 6 network. I only know about common router settings setups. I own a Mikrotik SXT Lte6 outdoor device that is currently using my iPhone's sim card. I was wondering if it is possible to receive sms and phone calls (standard or VoIP/VLAN) on my iPhone even thou it has no sim card and it's original sim card is in the mentioned router. iPhone uses the connection to it over wi-fi to get on the internet. My setup is a SXT LTE6 Kit (RBSXTR&R11E-LTE6) that utilizes the WiFi capabilities and normal bridge to another router (TP-Link 300 Mbps Wireless N ADSL+ Modem Router, Model: TD-W8961N (UN) Ver 2.0). My network carrier is MTN South Africa and obviously I am in South Africa. My cell is a iPhone 7.
