Czechia: SMS Features and Restrictions


In spite of being a small market with 10 million population, Czechia has more than 14m subscribers, one of the highest penetration rates in the world. The operators, especially T-Mobile and Vodafone have been filtering heavily and actively shutting international routes down, or imposing high interworking fees. 

Sender ID:

As of 1st September 2021, T-Mobile CZ will be rejecting any Alphanumeric Sender ID, that has not been registered with them. Vodafone and O2 will overwrite with SID "Info".  

Please reach out to your Account Manager or our Support team, to advise on what information is required to pre-register the SID for T-Mobile and the other CZ Operators.
