Hi all I have a problem, I have an alcatel Y858V wireless LTE router but it's seems to be locked to mtn, though when I connect it to my laptop and open the page to control the router it allows me to create a profile for Telkom but it still doesn't work, I changed the apn but it doesn't allow me to change the IP address, it says it's invalid. Does anyone know how to unlock this router? It opens up an mtn menu. When I inserted a Telkom sim and the menu popped up it didn't ask for a NCK number so it doesn't seem to be locked. The SSID is MTN internet.
