I just bought this new Galaxy phone and for some reason I'm not able to receive my mother's texts. I'm not sure about anyone else but I do receive others that I have texted recently
Try installing Google messages and also Google carrier services and then reboot your phone, if you are still having issues make sure you don't have her blocked see if you can receive a text message from someone else
these are often carrier related, so I suggest talking to the carrier to see if they've come across similar issues and if they have a fix or not. If you don't receive the help or fix you need then submit error report to Samsung Members after reproducing the issue.
share the device's model number, carrier, and software version please. thanks
