I'm trying to administer the SMS trafic of my businesss centrally through a web portal.
In Europe (except UK) we don't have a numbers/SMS trafic provider like Twilio or Clickatell, nor any build in way to administer the SMS traffic for a number via http, so I will have to buy the long numbers and administer the SMS traffic myself.
For this I was looking into a hardware solution for hosting all my SIM cards - I have like 400 sims cards (= numbers). I saw that GSM modems might fit in but they don't seem to scale up very well.
Could you recommend me a GSM modem? If this is not the best way to approach this, what would my alternatives be?
Thanks in advance
Off topic? - this is related to hardware - more exactly hardware architecture. If anyone else ever confronted with a similar challenge his/her experience would help me. – Ando – 2012-06-01T12:22:58.580
