We use Stripe as our payment infrastructure for our SIM Only options. During the initial sign-up process, you will be prompted to provide your payment details, which will be securely saved by Stripe for future monthly charges. This means that you won’t have to worry about manually renewing your subscription each month, as Stripe will automatically charge your card on file. If you need to update your payment details or have any questions about the payment process, please don’t hesitate to contact us via our Live Chat service or email.
