Sender ID and number filtering restrictions
Some mobile operators filter text messages that are sent using alphanumeric or numeric Sender ID. In these cases your Sender ID is changed to a random number in order to ensure delivery. This is called sender filtering.
Two-way SMS service is guaranteed to work only in the countries, where we offer local dedicated numbers.
Alphanumeric Sender ID is a paid feature and only available in select countries. Replies are not supported with a Sender ID. Supported countries include:
- Australia
- United Kingdom
- Ireland
- Germany
- Switzerland
- Majority of the EU countries
