Zambia is a growing market for sms in Africa and is rapidly expanding. The operators are filtering cheap SS7 routes and are making it more and more difficult to get messages delivered. Only direct routes approved by the operator are ensuring message delivery. Nexmo is pleased to announce that we now have a direct route to all networks in Zambia via MTN Zambia!
This is now our default to all networks in Zambia (MCC=645). Sender ID is dynamic and delivery receipts are supported for Airtel (64501) but not for the other networks as yet, therefore DLR latency should not be used as an accurate measure of delivery time.
