Opportunities and limitations - Czech Republic
Despite being a small market with 10 million inhabitants, the Czech Republic has more than 14 million subscribers, which is one of the highest penetration rates in the world. Operators, especially T-Mobile and Vodafone, filter heavily, actively shutting down international routes or imposing high cooperation fees.
From September 1, 2021, T-Mobile CZ will reject alphanumeric sender IDs that have not been registered with them. Vodafone and O2 will overwrite with sender ID "Info". Numeric sender IDs are not allowed unless they are SureSMS leased Czech LVNs that support SMS features. Contact firstname.lastname@example.org to confirm availability and for help pre-registering your sender ID for T-Mobile.
There are no additional content restrictions beyond those in our Acceptable Use Policy.
