I also wish to have a three or four digit shortcode that works on both the Vodafone and Telecom networks.
What are my options of doing this, so far I have only been able to figure that
- I could interface a GSM modem/cellphone to send and recieve sms messages, and parse the data in a script. However, It seems that interfacing with a datamodem etc doesn't work or won't work on the telecom network (Eg CDMA datamodem that sends sms), and also means I can't have a shortcode (I'm not completly sure)
- I could use a third-party gateway like clickatell, who support two way SMS. This seems like a good option but again it looks like it doesn't support NZ shortcodes?
- Direct connection to the SMSC's of both the Telecom and Vodafone networks (using SNPP/XML etc (whatever the SMSC's protocols are)) -- This seems REALLY expensive, but eventually i'm assuming will be the way to go.
Is there any more options? Using a NZ third-party gateway? Also does any one know a rough pricing on the last option for both networks?
