How do I use my Nokia Lumia 635 with Target's Brig...

Question

I purchased my 635 on eBay and the seller said it was an unlocked phone. When I put the Brightspot SIM card into the phone, it asks me which "Cellular Connection Profile" I want to use for the SIM card, and the only two options are T-Mobile or MetroPCS. I spoke to Brightspot customer service twice. One person told me to select MetroPCS. The other told me to select T-Mobile. I'm still waiting for my service activation to be completed, so I can't actually test whether either one will work, but I need a definitive answer ASAP since I have a number transfer in process and will lose my Verizon service shortly. And clearly Brightspot techs have no clue.
I was told that if the phone were locked, it would prompt me for an unlock code. This is not the case. The only thing it prompts me for is which Cellular Connection Profile to use. Does anybody know which profile I select for use with Brightspot? Or if I need to change a setting elsewhere? Or have I been misinformed and this phone is actually, in fact, locked? Please advise, I would greatly appreciate it. Thank you!

It sounds like the phone is simply asking which internet access point it should use for its data connection. Brightspot is not a network provider itself, looking at its web site it is just reselling airtime on the T-Mobile network.
It might be the case that you can just use the T-Mobile access point. However, if Brightspot is quite a new operator, the database used to select the access point might not have Brightspot details in which case the access point would need to be configured manually (access point info would be provided by Brightspot). Exactly the same thing happend some time ago with the French service provider Free.
