There are no known restrictions on Sender ID to most of Germany.
26243 (Lycamobile) does not support numeric Sender IDs and all will be changed to NXSMS. Alphanumeric Sender IDs are supported and will not be changed.
As of April 2016 Social Invites are not allowed by T-Mobile Germany.
Our direct link to Germany is otherwise fully-featured, including support for:
- Dynamic Sender ID
