How do I pay for the services?
If you are on the free plan you do not need to pay anything. If you have a paid plan you pay for subscriptions in advance using Credit Card, Paypal or similar. Future charges are deducted from your registered payment method. You can request to get an invoice to refill your Sonetel prepaid account with an amount you choose, from which renewal charges can be deducted.
Enterprise customers get invoices in advance, with customary payment terms.
