Did you have to give your provider a mac address when u first subscribed? If yes then a new provider would need that. Since it is an Enigma box, you would need the provider, someone like me to connect you. I you want to try a trial and see if works pm me. Have fun and smile.

Looks like its an Enigma2 device. Both m3u and mac-based subs should work. Plenty of tutorials on google. Including this one https://support.franqie.com/support/solutions/articles/26000032336-how-to-setup-iptv-on-enigma2-dreambox-vu-etc-
