Samsung Galaxe S21 Phone Can't Send Text Messages

[mariaceciliajoy]

Hi everyone! My Sansung Galaxy S21 can't seem to send text messages to specific numbers such as those on radio stations like 99999 or to respond to automatic messages from stores etc. I have no issues with regular numbers.. Just the ones that are less than 10 digits.. Thank you!

Hello Mariaceciliajoy,

  Welcome to the community!

  Often, those type of numbers can only receive SMS and not MMS. It's possible that your phone is sending MMS by default. You should note that multimedia message services (MMS) are not limited to just photo or video messages. Some phones allow users to add Subject lines to their messages -- similar to the subject lines found in emails. Adding a Subject line automatically converts a SMS to MMS. A blank subject line may also still be considered a MMS. It's possible your phone is automatically including a subject line (blank) and sending those messages as MMS.

Hope this helps 😀

Cheers
