We are planning to develop the push notification service for a telecom operator. But I haven't got any information whether the APNS push service is free of cost or should we make any payment?
My questions are,
- Should I pay for using the APNS push service?
- If operator want to sent push notification to millions of subscribers, should we pay to Apple or is it absolutely free? If not free, please share the URL where payment details are available.
- Is there any limit for the number of notification sent or the number of subscribers?
