Payment on the Mobile Internet
When you use your smartphone to browse the Internet via the mobile network, shopping becomes even easier. After making a purchase on a carrier's site, you'll be redirected to your mobile carrier for payment.
The respective network operator recognizes your phone number and provides a payment page for you to confirm your payment. Therefore, there is no need to enter the phone number beforehand. After confirming your payment, you return to the provider and can immediately use the purchased product. You will see your payments on your next mobile phone bill.
