The platform does not have the ability to discriminate between landlines and mobile phone numbers; however, it is our experience that messages to the following do not get sent:
- Nonexisting numbers
- Wrong numbers
As for disconnected numbers, it would depend on the carrier. Still, some of the above cases do go through and are charged as successful messages, so we urge you to clean up your list as best as possible to avoid being charged for messages that ultimately will not arrive at their destination, as we are not responsible for those.
