For 13,000 tooman per 3 months you can have VPN and watch Youtube in perfect speed in Iran. and a good investment to save you from looking utterly silly here with your ignorant posts in front of mashdi who spends a good deal of time in Iran and knows what he's talking about and watches Youtube in Iran on a regular basis without any problem. give it a rest kid with your embarrassing posts.you don't know jack about this subject.
You got horrible internet advice in your somewhat annual 2 week trips to Iran. next time go to a decent coffee-net and learn a few things about how to use Youtube with VPN.
