Solution for locked network

[Woodyyy]

I got a phone(Galaxy s24), apparently it's locked to tmobile. I was wondering since I'm already a tmobile customer with a phone that's unlocked (Galaxy s10e) if tmobile would unlock so I can put my sim in the new phone.

If it is locked to T-MOBILE and you already have T-MOBILE sim card, you should be able to just place sim from old phone to new. It should work.

I don’t see a issue with having your sim transferred to your new S24 just contact T-mobile once you put the sim in the new phone to make sure it transferred over properly

Locked to a carrier only means that you can't put another carrier's SIM in while it's still locked.  You are not, however, prevented from using a SIM from the carrier it's locked to.  You may get a text from T-Mobile to confirm it's you who transferred the SIM.

It appears the device is experiencing intermittent connectivity to the network provider. Upon attempting to switch SIM cards, I am presented with an indication that the network is locked. Furthermore, I have observed that the previously removed eSIM continues to be displayed within the device's settings.

I would suggest contacting T-Mobile they may need to add the new phone to your account

Do you think I'll have to end up paying for the phone too?

[GaryB82]

What do you mean "pay for the phone"?  Didn't you already purchase the phone and pay for it 

[Woodyyy]

I have a strong inclination that the prior owner's failure to settle their account is the root cause of the problems I'm experiencing.

That would cause the issue I would contact T-mobile and have them check to see if the phone still has a payment and if it does return it to who you purchased it from
