Yes. You can block another TextApp user (i.e. +T123 number).

If you want someone not to be able to call or message you on TextApp number, you can use the Block feature. It will block both - incoming calls and messages sent by that sender.

To block a number inside the app, from a received message on the Chats screen:

  1. From the list of senders, tap the one you wish to block.

  2. It will show a screen with chats with that person. On the top right of the screen, tap More

  3. Tap Block from options.

We are working on enabling you to block a real number (i.e. Sim number).
