@Rachels Try a network reset and restart your phone if it doesn't automatically do so.

Samsung Galaxy S8 / S8+ - Reset Network Settings

From a Home screen, touch and swipe up or down to display all apps. ...
Navigate: Settings > General management. ...
Tap Reset network settings.
Tap Reset settings.
If applicable, enter the PIN, password, fingerprint, or pattern then tap Reset again to confirm.

@Rachels I have a Samsung device and from what I remember, invalid sim is a message that indicates the sim doesn't have active service. Does your sim still work if you try it in another phone?

@Rachels

clear your cache:
goto Settings > Storage > Internal Storage > Cached Data.

toggle airplane mode
manually select public mobile
1. Open Settings>Connections>mobile networks>network operators>search for networks
2. Tap the network you would like(Public Mobile)
or you can let it automatically search for the network
3. Restart your phone

factory reset your device

contact Samsung if you recently did a software update

Still no solution but I have also tried, resetting the sim manager app and forcing a stop. then resetting it and rebooting my phone. but that didn't work either.

This did not do it. Do you have other suggestions?

@Rachels can you test the sim in other phone to check is it the issue with sim or phone?

@Rachels if your sim doesnt work in the othe phone, please log into your self sevice account and choose the change sim option and compare the last 4 digits to the sim card in your phone. The Sims should match.

If they don't, then you may have been sim jacked. Change your password and name on the account. Immediately place your phone on lost/ stolen. Change email, bank, credit card passwords that may be at risk. Contact the relevant places.

If they do match. Then try these tricks to reset your service. You could try in order:
1.Restarting your phone. Turn it off, remove the SIM card, reinsert it, wait 5 minutes and restart it.
2.Putting your phone on aeroplane mode for 5 minutes. Take it off and restart.
3.From your self service account enable the lost/ stolen feature log out, wait 5 minutes, log in and take it off. Log out and restart your phone.

In both cases, contact the moderators. In the former contact them and ask them to switch your service back to the original SIM card. In the latter, contact them and ask them to reset your service.

@RossN et al From Android novice:

a) Do Samsungs sometimes relock to original provider after update?

b) Could the new OS be missing a matching carrier profile? Maybe Androids don't have them.

c) Try "safe mode"? https://www.maketecheasier.com/fix-no-sim-card-detected-android/
