In spite of being a smallish 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.
Nexmo is pleased to be able to offer local direct connections. In line with local regulations, the Sender ID will be changed in compliance with operator restrictions to ensure delivery. All other features such as binary and concatenation, are supported.
Sender IDs are all overwritten generally to a local shortcode but also occasionally to an alpha or random numeric sender.
