Bought a phone from eBay with an unlock code that was "successful" but still locked.

I bought a BlackBerry Q5 from eBay and want to use it for the T-Mobile USA network (I'm in the USA and this is the only way I could get the phone). I know BlackBerry Q5 model SQR100-1 works for T-Mobile USA.

The  eBay seller sent me an unlock code, but even though it said "successfully unlocked" when I entered it, the phone is still lock. I was reading that Telus needs 2 codes to unlock. A MEP2 and a MEP4 code and the seller also sent me one of them. I tried to get a code from an unlock company but it was the exact same code as the one the seller sent me. Is it even possible to unlock then ?

That's a risk you take when buying phones from eBay. Most of those third party unlock companies are scams. If the phone was truly unlocked, they would have shipped it that way and not required you to enter codes (which don't often work well).

How do you know the phone is still locked after using the code? What message are you seeing?

Are you using a T-Mobile SIM after unlocking it? If you cannot activate service with the T-Mobile SIM it's possible that the phone has been reported stolen and is on the activation black list.

The phone is brand new. It arrived in the original packaging. It's a prepaid phone from Best Buy canada (I'm the usa btw). 

I don't think the phone is stolen. From researching it seems to be a problem specifically with Telus phone (Either a blackberry issue or a Telus issue). The phone doesn't appear stolen or reported.

When I entered the unlock code the seller sent me it said "Successfully unlocked" but when I entered the T-mobile sim card the phone was still locked.

The phone is carrier locked if it's prepaid. Many of the third party phone unlocking companies are scams as I've said and don't always work. You could try approaching the carrier it's with, but if there is no active account, there is no guarantee they will unlock it.
