If you’re looking to chat with friends on TikTok without having to use your phone number, there are a few ways to go about it. One option is to use the app’s messaging feature. You can type in a message and send it as a reply to someone who has already sent you a message. Another option is to use the app’s voice messaging feature. This lets you record a message and send it as an audio message. You can also share videos with voice messages by tapping on the three lines in the bottom left corner of the video screen and selecting “voice message.” If you don’t want to use either of these options, you can also send messages through Instagram or Facebook Messenger. Just open those apps and search for “TikTok” in the search bar at the top of the screen. Then, type in a message and hit “send.” ..
