Hi, We suggest you to please try to reset network settings on your phone and check the issue again. 

1. Go to Settings, and then select General management.

2. Find and select Reset.

3. Choose Reset network settings.

4. Tap on the Reset settings button.

5. Tap on the Reset button.

Note: When you reset the network settings, the Wi-Fi and Bluetooth information connection are reset

Two different devices, with the same issue.. Sounds like it's either a SIM card or Carrier / Network issue. 

• Remove the SIM & Reinsert the SIM.
• Run the Diagnostics for the SIM & Network from Samsung Members app / Support. See if you get any error messages. 
• Try a new SIM card.

Or, from your other post, maybe both your phones got wet..
