How To Fix Signal Cannot Send Messages Issue

The Signal cannot send messages problem usually occurs when you are trying to send out a message to a person or group of people. There are several factors that can cause this issue such as a poor internet service, a VPN, or a large attachment that hasn’t been sent out yet.

Signal is a popular encrypted messaging service that’s available for the Android, iOS, Windows, Linux, and MacOS platforms. It works the same way as other regular messaging apps with users able to send one on one message, create group chats, send stickers or photos, and make voice or video calls.
