Xbox live prepaid card error

Here is a handy page if you have trouble redeeming
Xbox prepaid cards

The most relevant solution for you is to check the Xbox Live service status. If there are any issues here,
try to redeem the prepaid code later

Are you trying to add prepaid gold cards or did you add a gift card and are trying to buy Live with the money from those?

If you're trying to add a prepaid gold card, what error message/error code do you get when you try redeeming on the console?

If you added money to your account, it's not possible to purchase gold with that money. That money can only be used to purchase games and other contents from Live. Gold can only be purchased via credit card/Paypal or by purchasing a prepaid gold card.

okay i went to he store and boughta prepaid card for my xbox live but im geing 2 error codes now 80153021 and 801613FB

Here’s what the Xbox support website-
https://support.xbox.com/en-SG/billing/prepaid-codes/prepaid-code-errors states for the following error message:

This code wasn't activated by the retailer. Contact the store and have them activate the card

All codes must be activated at the point of sale in order to be used on Xbox Live. Sometimes there can be a delay at the retailer when activating. If you receive this error message, wait 24 hours and try again. If the card does not work 24 hours after purchase,
take the card back to the retailer along with your proof of purchase and ask them to activate it.

I have the same error.

I buy an xbox prepaid card for $ 24,99 valid for 3 months xbox live gold membership and the activation not work. The system show me an message "INVALID CODE".
