You should google about this provider. Its market leader in the place where I come from.
I am using iphone, this phone is not common at all?
Really? You want me to spend hours on it and find how many people are using these?
It looks common but combining all those characteristic it may look uncommon IMO, see above picture both of you also come from Estonia too.
Sure, bring here an another user with these criteria (come from Estonia, using red circle, Telia provider, Iphone and white square in Telegram.)
I don't know how you've fallen for this guy since he already has 3 standing red trust to prevent others from getting scammed in the future. He doesn't have an imposter in Telegram, he just wants you to think that way so he can scam more people.
The thing is, the scammer didn't get red tagged before OP trade with him.
