Samsung Galaxy S9+ unlocked won't connect?

[demonicvampiregirl]

I have a refurbished Samsung Galaxy S9+ from a different website that isn't the carrier (backmarket) it was said it was unlocked to work with T-Mobile, Sprint, AT&T and Verizon. Well, Verizon is the service I want to use and the sim card I have installed. Apparently on StraightTalks website, my phone is active. However, booting my phone it still says T-Mobile and I cannot call, text or even use data on my phone. I have tried everything suggested from taking the sim card out, rebooting my phone every 20 or so minutes for an hour, to changing some settings in the phone.

Anyone got suggestions on how to help? It's supposed to be switching to Verizon but wont, it still constantly says T-Mobile. I don't want to send it back and I currently do not have a working phone as my Samsung Galaxy S6 is now deactivated due to them switching the service.

If it shows the t-mobile logo when you power the phone on then I think it means the phone was (and maybe still is) locked on t-mobile.
Go to settings, about phone, status, sim card status.
What does it show there?

It says network not available, mobile network state is unknown, service state is out of service, IMS registration status is not registered, signal strength is -113 bDm 0 asu, mobile voice network type unknown, mobile data network type unknown, and roaming is not roaming.

We even contacted t-mobile and they said it wasn't locked. So I have no idea what to do from there. I even tried a trick I saw on a YT video, but I think my connection in my house isn't helping for that. May have to go somewhere else and try it.

Have you tried a factory reset? That would be the first thing to do when buying a second hand phone.

No I have not. Would I need to take my sim card out before I do this or would it be best if it was left in? I don't got much time to do it right now so will do so in a few hours, will message when I do.

Go to settings >about phone >software information> post a screen shot of that page .

Then go to settings >connection >mobile network >access point > screen shot of that and network tap with screen shot.

I hope these are correct. Was not sure which one you wanted for the network tab.

You can leave the sim card in.

You can leave the sim card in.

Alright, thank you!

Let me know if you need anything else and if the network one is the correct tab you wanted. Will do the factory reset after you reply so I'm not messing anything up.

Yes, I want to use Verizon and the sim card is in the phone currently. Using StraightTalk for the provider.

Ok , just to verify you have the Verizon sim from taptalk in the phone?

Does this phone have the correct bands? Was CDMA on Verizon, now GSM on tmobile?

No, I have a StraightTalk Verizon sim card in, not a taptalk.

Okay, so I just noticed there was an app for T-mobile that would unlock my phone, going into it, it says it's locked. Would a factory reset fix that with the new sim card in?
