If you want to resize a video to send it as a text message, there are a few things you need to know. First, make sure that the video is in the correct format. If it’s not, you’ll have to convert it first. Second, make sure that your phone supports resizing videos. If not, you’ll have to use another app or software to resize the video for you. Finally, be sure that your phone is set up for text messaging. This means that you have an account with texting service and your phone is set up for text messaging. Once all of these things are in place, just go ahead and resize the video using the app or software that you’re using to create the message.
