Try...
• Reboot the phone to refresh the network signal.
• Clear phone inbox to ensure it is not full (for old phones with limited SMS capacity).
• Check if there are any phone applications/settings that are filtering SMS added recently.
• Alternatively, you may swap the SIM to another phone to verify if the delivery issue is phone related.
• Check if you are in roaming.
Also check with the network provider as some may block the notifications coming in. If the issue persists contact customer services.
