Hi David,

Leave the SIM card in the phone and try turning off the phone completely for a minute or two. Power back on and see if that resolves the problem. Make sure airplane mode is not enabled and that your phone is set to a network type other than 2G/GSM, (e.g. LTE/WCDMA/GSM (auto) or WCDMA Only. ('Network type' options are found on the same page where network operator options are located).

Are you located in an area that normally gets adequate signal? How old is the SIM card?

It is possible that a SIM card could fail despite it's age, though this is quite rare. The next step is a factory reset. You can use the software method to reset the Note 4 or the hardware method shown below. The hardware method allows you to wipe the cache partition (recommended) and appears in the same menu as wipe data/factory reset. Both methods wipe the device of all user content.

1. Turn off the phone. If the phone will not turn off, remove and re-insert the battery.
2. Press and hold the following three buttons at the same time: Volume Up key, Home key, Power key.
3. When the phone vibrates, release the Power and Home key but continue to press and hold the Volume Up key.
4. When the Android System Recovery screen appears, release the Volume Up keys.
5. Press the Volume down key several times key to highlight ‘wipe data/factory reset.’
6. Press Power button to select.
7. Press the Volume down key until ‘Yes - delete all user data’ is highlighted.
8. Press Power button to select and start the master reset.
9. When the master reset is complete, ‘Reboot system now’ is highlighted.
10. Press the Power key to restart the device

Did both the wipe of the Cache Partition and factory reset and the issue is still present

Then it's likely a defective SIM card or the mechanism that reads the card could be faulty. Bring the phone to a Koodo kiosk and have them try a new SIM card first. Keep us posted.
