Invoices and Payments
Payment Methods
Payments are processed by Paddle as our Merchant of Record. Paddle supports credit/debit cards (Visa, MasterCard, American Express), PayPal, and local payment methods depending on your region. Your payment details are stored securely by Paddle — SIMtrix never sees or stores your card information.
Invoice History
View all past invoices in the Billing section of your dashboard. Each invoice shows the billing period, plan, SIM quantity, amount charged, and payment status. Invoices are also sent to your registered email address.

Updating Payment Method
Click "Update Payment Method" in the Billing section. This opens Paddle's secure payment portal where you can change your card or switch to a different payment method. Changes take effect for the next billing cycle.
Failed Payments
If a payment fails, Paddle will retry it after a few days. You will receive email notifications about the failed payment. If the payment cannot be collected after multiple retries, your account may be paused until the payment is resolved.
Taxes and VAT
Paddle handles all applicable taxes and VAT as the Merchant of Record. The displayed prices include or exclude tax depending on your region. Invoices include full tax breakdowns as required by local law.
