I bought Xbox Game Pass for PC 3 Months Trial, but i dont have credit card.

Unfortunately there is no way to use the code without a Credit Card. As soon as the free trial is over, you will be charged for the subscription.

Also it’s not a trial. I bought the Xbox Series S starter bundle with one controller and a 3 month ultimate game pass

Game Pass Ultimate is a recurring service...whilst it is a 3 month initial deal, you are committing to an ongoing service (which can be cancelled) and so require credit card to pay for the service once the "trial" has expired. I presume this is the issue here

Hi, thanks for the reply. I have the 1 month trial (with credit card), and it let me download the two Xbox one games. It's just the Xbox 360 one I can't download.

Also, the Games With Gold FAQ (support.xbox.com/.../games-with-gold-faq) specifically says the Gold membership trials with credit card are elligible.
I did input my credit card info.

Thanks again!

Rei,

If you EVER used Game Pass for PC.. you can't get the deal.

I thought it applied 3 months of Game Pass PC ON TOP of what you already had.

So really, it's a 3 month trial period.
