Is your Samsung Galaxy phone throwing a ‘Not registered on network’ error? Well, you’re not alone. Several Android users have reported similar instances where their phone cannot connect to a network, thus not being able to make or receive calls and texts.

Top Ways to Fix Not Registered on Network Error on Samsung Phones

There can be plenty of reasons why your Samsung Galaxy phone might fail to connect to a network, right from misconfigured network settings to a faulty SIM card. We’ve mentioned all the possible solutions that should help you get past the error in this post. Assuming you've already tried restarting your phone, we'll look at some workable solutions.

1. Reinsert the SIM

One viable reason behind this error is improperly inserted SIM. Therefore, you should take out the SIM and insert it again. Also, make sure to inspect the SIM card for any visible damage. Turn off your Samsung Galaxy phone and take out the SIM card. After reinserting the SIM, reboot your phone one more time to see if that fixes the error.

2. Select Network Manually

3. Change Preferred Network Type

Sometimes, these network registration errors can also occur if you're in an area where the set network type is unavailable. You'll need to switch to a different network type to remedy that. Here's how to do it.

Step 1: Open the Settings app on your phone, navigate to Connections, and tap on Mobile Networks.

Step 2: Select Network Mode to choose LTE/3G/2G (auto connect).

If that doesn’t work, try switching to 3G only or 2G only.

4. Update APN Settings

You'll get such errors if you've recently changed your service provider or migrated to a different plan with the same carrier. You can try to resolve them by manually updating the APN (or Access Point Name) settings. You'll need to contact your service provider to get these settings.

Once you have the required settings, here's how you can update them.

Step 1: Launch the Settings app, go to Connections, and select Mobile Networks.

Step 2: Next, go to Access Point Names.

Step 1: Open the Settings app on your Galaxy phones and scroll down to select General management.
