Hi Mate
Take it from me, most providers have moved away from MAG/MAC and Stalker portals these days.
These portals are easily detectable, and ISPs block them very quickly in a lot of cases. That’s why the majority of IPTV companies now prefer devices that support VPN installation. It gives users a backup if their ISP starts blocking the connection.
If you’re looking for something more reliable long-term, I’d recommend going with an Android-based device that can run a proper player + VPN.
