After linking your mobile number to WeChat, follow these steps to add friends from your mobile contacts:
- Open WeChat and tap「+」in the upper right corner.
- Select「Add Contacts」>「Mobile Contacts」.
- Follow the instructions to upload and view your mobile contacts.
- Tap「Add」next to the contact you want to add as a WeChat friend.
Note: Uploading your mobile contacts does not automatically add them as WeChat friends. They will only be added after you tap「Add」and they accept your friend request.
