Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
You can simply select Paypal when purchasing our PRO plan:

If the purchase fails, please ensure that your payment method supports the following:
– Payments in USD $
– Supports subscription-based payments
– International payments are turned on
Also, ensure that you are not using a Proxy or VPN? You should use your actual ISP to make the purchase.
Please select your country at the upper right corner of the pricing page and let us know if you are able to purchase with Paypal.

Let us know how that goes. Looking forward to helping you.
Hi there,
Thanks for your prompt reply.
I’m in China, but I want to pay Rank Math Pro by PayPal, can I pay by PayPal?
Regards
Bella
Hello,
Unfortunately, FastSpring (our payment gateway) doesn’t support Paypal in China as stated in their document here: https://fastspring.com/docs/payment-methods-accepted-by-fastspring/

I would suggest using a different payment method such as accepted cards.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
