S9 Cannot Send Text Message If No Wi-Fi Signal Available


Problem: I have a Samsung Galaxy S9. When I try to send a text message in an area that doesn’t have wi-fi, I get the following error message “unable to send this message. Your device is not connected to a mobile network. Connect to a wi-fi network and try again”. How can I update my settings so that I can text on my mobile network? Thanks in advance for any guidance you can provide.

Solution: Are you in an area with good mobile signal reception? If not then you won’t be able to send out a text message. Some carriers such as T-Mobile offer a service to consumers located in areas with low to no mobile signal where calls and text messages can be sent and received when the phone is connected to a Wi-Fi network.

If your phone has a mobile data signal then make sure to check the phone settings and make sure Wi-Fi calling is off.

  • From any Home screen, tap the Apps icon.
  • Tap Settings.
  • Tap Connections.
  • If necessary, slide the Wi-Fi Switch right to the OFF position.

If the issue persists then you should consider doing a factory reset. Just make sure to backup your phone data before doing the reset.

S9 Not Receiving Text Messages

Problem: Hi there, I just recently got the S9. It hasn’t even been a month yet, and it’s already giving me problems. It started yesterday, when at first I was not receiving messages from contacts until hours and hours later or not at all. I’ve read the forum here looking for a solution and i’v tried all of them except for contacting the carrier. Is there any other options I could try before I get in touch with them? I tried the SIM card solution, I tried restarting my phone, putting it in safe mode (still had issues). Nothing has worked. this morning they did a software update and once it was finished I got a whole slew of messages from people from last night. Only thing is I don’t know if the issue is resolved yet or if it was just for that moment, because it seems like i’m still having issues with not receiving messages when they are sent. Are there any other solutions I could possibly try?

Solution: Since you mentioned that you are now receiving text messages after the software update then I suggest that you backup your phone data then do a factory reset. Once the reset is complete do not install any apps in your phone just yet. Try to check first if the issue still persists. If it does and your phone is getting a good network signal then it’s time to contact your carrier regarding this matter as this might be an issue with their network.

S9 Not Getting Picture Messages

Problem: Hi, I am having issues receiving images on my Samsung S9. People from iPhone and Samsung phones have sent me pictures and I get an error message that starts saying for example the recent one “No subject. Message size 112KB, Expires 10:15am, Jun 3”. When I try to download it, I get an error message that says “Error: Network Error Occurred”, although I see a couple bars on my phone signal. I have unlimited internet on my phone, and don’t use too much data. This weekend, a friend sent me a set of pictures, it went through. She sent me another set, and it didn’t, I got error messages. Then I asked her to resend it, and it worked.

Solution: For this particular issue you need to make sure that your phone has an active mobile data subscription and that the mobile data switch of the phone is turned on. You also have to make sure that the APN settings that your phone is using is the same one as that of your carrier.

S9 Text Message Sending Failed

Problem: Galaxy S9. Periodically I will get a notification of a failed message to so and so. When I click on the notification it takes me to the texts for that person, but there are no messages that say failed . Everything has gone through fine. If you tell me why/ what is causing this I’d be very grateful. Thank you

Solution: For this issue you should try clearing the cache and data of the text messaging app from the application manager. Once this is done check if the issue still occurs. If it does then start the phone in Safe Mode and check if you can now send text messages. If you are able to then the problem could be caused by an app you downloaded. Find out what app this is and uninstall it.

If the above steps fails to fix the problem then you should backup your phone data then do a factory reset.
