# Do I need a credit card to sign up for oxio?

## ${color}[#000000](To sign up for oxio services, you’ll need a valid credit card.)

For account security, your **first payment requires a valid credit card (VISA, Mastercard, or AMEX) or a Visa/Mastercard Debit**. You can change this to your preferred method immediately after checkout in the Client Portal.

Your **first payment covers your first month of service**. Your billing cycle only begins once your equipment arrives and your service is activated.

### ${color}[#000000](Can I use a Visa/Mastercard debit card?)

Most Canadian cards work, but we can’t guarantee compatibility with every bank.

### ${color}[#000000](Can I use a prepaid credit card?)

We’re unable to accept prepaid credit cards from banks or stores.

## ${color}[#000000](Why is a credit card required?)

A credit card is required for two reasons: **instant payment processing** and to establish **liability** before shipping your equipment. If your first month is free due to a promo or referral, we still charge and immediately refund $1 to verify the card's validity.
