It's also possible to send money to international numbers, as long as the recipient is already registered with MBWAY.

MB WAY is a payment method where the client inserts his mobile number (registered in MB WAY system with an MB Card) and receives a validation message to authorize the payment. To pay in stores, customers use QR code.

Call of Duty Warzone is a free to play game. It's not on GamePass and it doesn't need Xbox Live Gold either. MW2 and its multiplayer component is not free. You need to buy it if you want to play the single player game or MW2 multiplayer.
