Product Name: Samsung Galaxy S10 128 GB in Black T-Mobile best
I have a very nice Galaxy S10 in very nice condition. It has not been used much and it is for T-Mobile or Metro by T-Mobile. I bought the phone hoping that it is unlocked because I have AT&T but it is not unlocked. I sold the phone on here and it got returned because the customer said the service would come and go. They claimed it was an issue with the phone. I do not have T-Mobile to test it so I am selling it as is for parts no returns. Buy at your own risk. It might work perfectly or it might cause you problems. You will get it at a best great price and you can always use it on Wi-Fi because I did connect it on Wi-Fi and it works great on there. If you have any questions please ask.
