I'm a reseller for ace and I do ask for the mac address for smart iptv cause it can be more convenient for me to do than the customer so it's not a scam
I would recommend if you want to watch IPTV services on your TV's you need to see if the services you want support Smart STB which is an app you install (it's available on Samsung and LG). Smart STB acts as a bridge between you and the IPTV services provider, so you have to give them your IP address so your TV can connect to their portal but from there they give you an IPTV MAC address which you give you our IPTV service provider. I have used them for a couple of years now, with no problem. You can find them also on FB if you want to check them out...but again its dependent on your IPTV Service provider to support their network.
Avoid, can't you see the fake pic he has? And gives no channels or package.
Ask for a trial here, lots of proper providers.
Purchase th Smartiptv app from siptv.eu, sure install it first on your TV, you have 1 week trial, then purchase it 5.99 and you upload your own channel lists from providers, no need to give the MAC to anyone.
Any paid IPTV service is going to require a mac address
Some providers like myself will take the Mac and do all the work for you (loading m3u into siptv, easier for most if I do it). But yeah strange they wouldn't provide any information before hand.
