Samsung S7 Losing Connection to Network

I've had my phone for about 4 months now, and until recently it's been great.  In the last month or so, I've noticed that my phone keeps losing connection to the Koodo network.  It will struggle to hold a connection at 4G, and then it loses connection completely to where my texts don't send and I can't access the internet.  A reboot of the phone fixes the problem for about a week, and then it happens again and I start the process over.  Is this a phone issue, or a Koodo/SIM issue?  For the amount I paid for this phone from Koodo, it had better be a Koodo issue!

You can try resetting network settings. If that doesn't work, you can see if another sim works fine in your phone, and vice versa to see if the problem follows.

Try going into your settings then click on network settings - mobile networks - network operators - search networks, it will search for the availabile networks and can take a minute or so then a list of available networks will pop up, select Koodo.

This has helped me with phones in the past so worth a try.
If it still occurs try to change the network mode to WCDMA Only. You may be right on the fringe of LTE and the phone could keep getting stuck searching for that LTE signal instead of switching to a the better connection.

If your phone received an Android system update/upgrade recently, (as mentioned in a similar post), then a factory reset may fix the problem. A factory reset is often suggested when a phone experiences software glitches after an Android update. The reset will wipe the contents of your phone, (excluding anything stored on an SD card, if installed). Backup anything you want to keep before proceeding with the factory reset. Make sure the battery has at least a 70% charge.

The link to the video below shows two methods of performing a factory reset on the Galaxy S7. Both methods accomplish the same task. The first method is the easiest. It's best to perform the factory reset when you least expect calls or messages. The entire process can take up to thirty minutes or more to complete.
