How can I connect a Verizon, 4G unlocked Galaxy S5 to T-Mobile account?

[lk82563]

I purchased an unlocked Verizon 4G, Galaxy S5 and want to connect it using my T-Mobile SIM card and account. I can use the phone but cannot connect to the internet on my account unless I'm using the Wi-Fi connection. How can I set up this phone to work seamlessly with my T-Mobile account? Thank you!!!

Did you contact T-Mobile already? That's the first step.
