IPTV Set-Top Boxes + Service provider

Please! I am new using IPTV, and I would like your advice and help.

I live and work in Russia, I have bought one year ago an Android TV Box to watch Tv, Youtube, etc.

H96 PRO + Plus Smart TV Box Amlogic S912 Octa Mali-T820MP3 GPU 3G/32G Android 7.1 2.4G/5.8GHz Wifi Bluetooth Set Top Box.
In my place, I have 800mbs of internet speed, so I won’t have a problem with this. And I have found a Normal IPTV provider here.

My question is:
Can I use this Android TV Box to watch IPTV or only using Apps? (With any App is more difficult, of course!). or Should I buy an IPTV Set like MAG 256 or the 322?
Please! Can you advise me, what to do? and What IPTV provider with Spanish or Latin American channels could you recommend me?

In Advance and from all my heart, THANK YOU VERY MUCH…! For You valuable time and cooperation!
I will be waiting for your soon answer!
With many respect,

Jean Paul Jenua

Thank You very much!
