How can I buy these game cards then? Maybe they can use the email address instead of the phone number?

We are truly sorry, sir. Customers are required to verify using a valid mobile number that is able to receive texts to purchase using the main payment selections. Shall you not be able to verify a valid mobile number, you can try using payment methods like Wire Transfer, MoneyGram, Western Union, PaysafeCard, OneCard or CashU (whichever is available in your country).
For more info, you may refer to the following guide: http://kb.offgamers.com/en/category/payment-option/
