iMessage on iPhone WORK PERFECTLY, even on Cellular, but no FaceTime. Please tell me why?

Hello to everyone on MacRumors forums!
Recently i bought worldwide SIM-Free iPhone from Duty Free Dubai shop.
I used my iPhone in Dubai very short time and i don't have iMessage and FaceTime option on my phone. I know UAE telecommunication laws and i know why people there don't have that apps.
But last week when i came in my born country i put new sim card without any restriction for iMessage and FaceTime, and when i open Message in Settings i saw iMessage "On/Off" toggle and i was surprised how it's that possible. When i switch toggle to "On" for iMessage, that function START WORK PERFECTLY FINE WITHOUT ANY PROBLEM EVEN ON LTE network.
When i try to do same thing with FaceTime i saw there is still no FaceTime menu in Settings. I search in my iPhone and i find everywhere FaceTime app (Notification centar, Celluar usage, Apps installed etc. etc...), i want to say FaceTime app is in my phone but is disabled and not showing somеhow.
Please someone who knows this situation to answer on my question: Can i enable FaceTime to work like iMessage works now on my iPhone?
Thanks!

Have you checked restrictions to see if it might be disabled there for some reason?

Check your language and region settings are set for the country you are now in?
