Follow these steps first:
1. Ensure that you have the most updated version of iOS. You can check for updates by going to Settings > General > Software Update. And if there is an update, you can follow the onscreen instructions to update your device. Updating your iPhone will also update the Messages app if you do not have the latest version installed on your device.
2. On your iPhone, turn on Airplane Mode (Settings > Airplane Mode), wait about 30 seconds and then turn it off.
3. Restart your iPhone. Here is how:
- iPhone X, 11, 12, or later: Press and hold the volume up (or down) button and the side button together until the power off slider appears on your screen. Drag the slider to the right. Wait about 30 seconds for your iPhone to completely turn off. And then press and hold the side button until you see the Apple logo.
- Other iPhone models: Press and hold the side or top button until the on-screen power off slider appears. Then drag the slider. Wait for your device to turn off. Then press and hold the side button again until the Apple logo appears.
4. Do you see “No service” or “Searching” in the status bar of your device? If this is the case, then try:
- See if you have signal. SMS messages require that you have a cellular signal.
- Make sure that you’re in an area with cellular network coverage. Go to another location and try there to get messages.
- Disable, wait 10 seconds, and then enable cellular data by going to Settings > Cellular or Mobile Data.
- Contact your carrier (Verizon, T Mobile, etc) to ensure that there are no issues with your carrier or account. Maybe you do not have enough to send/receive SMS messages.
