Czechia SMS Features and Restrictions


Overview

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

Sender ID

As of 1 September 2021, T-Mobile CZ 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 Vonage rented Czechia LVNs which support SMS features. Contact your account manager to confirm availability and for assistance with pre-registering your Sender ID for T-Mobile.
