Texts not being delivered

[Barrysh]

Hi. I have a Galaxy A52s. Recently about half of sms texts are not being delivered. They are just short texts. Less then 100 characters and no attachments or emojis.  Typical pensioner rarely have mobile data switched on and rely on WiFi. Never used to happen with my old A3. Probably settings but I don't think I have altered anything recently. An thoughts. Thanks

Hi @Barrysh Firstly check that there are no issues with your Network and enable Mobile  Data . check that your preferred sim  is assigned  to Messages, Settings-Connections-Sim card Manager.   check that Text is set as Default if that is preferred option, Settings - Chat Settings -Select Default Messaging Type, and set this to 'Text or Multimedia Messages'.   If you go to Messages- Menu(3 dots)-Settings-More Settings-Text Messages check that a number is poulated in the  Message Centre Section. If not you would need to  contact your Network.

otherwise  restart phone and check for any updates.  you may need to clear the Messages cache,Settings-Apps-Messages-Storage-clear cache.  If no solution try resetting the Network connections,Settings-General Management-Reset-Reset Network Settings.

However if all else fails possibility there is an issue with the sim card and you may need to reinsert or seek further advice.

I have an S25 Ultra with T-Mobile. About ten days ago, I discovered my outgoing SMS messages were not being received. Incoming worked just fine, and RCS with my Apple friends works fine. I've spent hours nearly every day since with their help desk and they just can't figure it out.....At my wits end.

I bought  a T-Mobile prepaid sim and it works fine, still T-Mobile is telling me it's a phone problem.
