Vasily, when you talk to girls, plant a seed about a cool activity that you would do together.
First, talk about the activity... "I have been dancing salsa for a while, the salsa club is an incredible environment with dancers moving so elegantly..." or "I have been to this shisha bar. It was such an adventure to try shisha for the first time...." Sell the idea with high energy. Then, tell her that you should do the cool activity together so you take the phone number just to do the cool activity. Talk for another five min or so and then leave. When you text, remind her the plan with a joke/teasing. She is more likely to respond now.
Good luck.
