-Question 2.
How do you exchange your contact information in English?
There are some structures for asking questions or answers related to contact information from social networks or in a more informal or casual setting. You probably want to exchange personal information on networks like Facebook, Instagram or WhatsApp.
In this sense, it is suggested to ask for contact information in a subtle way, such as:
Do you use Facebook? - Do you use Facebook?
Do you use Instagram? - Do you use Instagram?
Do you use WhatsApp? - Use Whatsapp?
This structure allows the other person to have the opportunity to respond to the request more loosely and without feeling pressured or uncomfortable.
Now, with an affirmative answer Yes, I do / Yes, I use Facebook, you can continue with direct questions to ask for the contact information. The formulation of the question will vary depending on the social network or contact form. For instance:
Can I add you as a friend? - Can I add you as a friend? (Facebook)
Can I follow you? - Can I follow you? (Instagram or Twitter)
Can I have your number? - Can I have your number? (WhatsApp)
