Try using Tor that the Brave browser provides as an option. See how you fare on it. You may also want to look at SPN in Portmaster from Safing if you’re on Windows or Linux. That’s another way to bypass censorship.
Also, seriously consider writing to Mullvad and getting server overrides for a few locations in the West. You’ll be better off. I live as an expat in the middle east so I have experience bypassing restrictions. Of course, Iran is a lot worse.
im sorry but i dont know how to dm in this forum i cant find private message thing in your profile.
Just click on their profile picture and you’ll see an option to message them directly.
I’ve double checked and Iran indeed can sometimes throttle UDP connections instead of dropping them. This explains why QUIC can be slow.
Obfuscation is only needed if WireGuard absolutely is blocked. OP has not confirmed this yet.
yeah thank you i did message mullvad for ip override files. also downloading spn thing to see how it works.
i’ve reached my maxium replis and have to wait for 15 hours but i dont have private message thing when i click on user’s profile picture.
also by wireguard if you mean to use wireguard software itself, that never worked for me.
no wireguard by default dsnt connect.
Do not try to use VPN and SPN/Portmaster installed at the same time. They will conflict with each other on your system.
No. I mean the WireGuard protocol that Mullvad uses by default.
Also, you editing your comments doesn’t notify me. A response is always best instead. FYI.
Well, I have shared all my options. Tor should absolutely work. Good luck to you!
Hey everyone. I understand that we are trying to help OP out here given their current situation and things got a little heated. Gentle reminder to keep respectful as we are all in the same team here!
You need V2Ray to an IP not known to be a VPN provider. Tor bridges should also work.
Anything else will at best be unreliable.
OP is in Iran. Wireguard is blocked.
I think this is the wrong place to ask advice related to extreme places like Iran. If you’re in Iran, your threat model should also be extreme as one mess up could mean that your life is over. A lot of popular privacy tools like Signal are blocked there, so it’s hard to recommend anything imo.
Is VPN use even safe in Iran if it doesn’t provide you with anonymity? You could be flagged for being a VPN user. I was just looking at The History of TOR Usage in Iran – Tech for Humanity Lab and it seems that Tor is super popular, but you have to use Tor bridges as lyricism mentioned.
Perhaps you can get it through here: VPN – ProxyStore
Thanks for hiding the crucial info regarding the graylists when attempting to use Wireguard in Iran 
With the caveat of IP not belonging to a datacenter. I was doing a couple of tests on an Iranian sensor and vless on CF CDN was reliable for the entirety of my tests run. Lower tier VPN providers tailored to the needs of the censored countries were also working as expected.
The selfhosted route is actually harder in Iran because of the relatively lower knowledge on censorship evasion, as evident by the fact OP wasn’t familiar with IRGFW. And you’re probably familiar with the Xray vs panels debacle. Iranians produced poor selfhosted guides resulting in mass banwaves.
Regarding the Tor bridges - they are detectable and their usage will cause the undesired placing in the graylist.
