Reasons and the situations when it cannot detect the network:

The problem generally started when users have upgraded it to the latest version of the operating system, after which the device was unable to detect the network and the error message appeared. This happens because the IMEI number of the phone is changed to ‘SN 0000’ after your device is updated and it also says that the SN number is broken and needs to be fixed.

Another reason why this issue can arise is when you are using a SIM card from a new network provider and your Samsung Galaxy S7 fails to detect it and it needs a little bit of help from your side by manually selecting the new Network Service providers name.

Removing the SIM and inserting it back helped many to solve the problem. Here are the steps:

• Turn off the phone and take the SIM card out.
• Re-insert it again and apply a bit of pressure to see that if the network can be detected. In these cases, there might be a problem that the SIM card is not connecting properly with the terminals in the SIM slot. Put a small piece of paper along with the SIM to help it connect to these terminals properly.
• Repeat this process up to 5 times to see if the device can pick up the network.
