GSM Modem is very slow. Sending 10 to 12 SMS Per Minutes [closed]

Question

I am using nokia 5233 GSM Modem with SMS Caster. I want to send bulk SMS to my clients but my GSM Modem is very slow to do that. It is sending only 10 to 12 SMS Per minutes. I want to use my cell number and sim to send SMS but with very high speed. How cold I find an altrnate to my Cell's GSM Modem.

Answer 1

GSM Modems or phones are not designed for sending bulk messages at high rate. You will need to either get in touch with some bulk SMS providers or virtual-number providers that lets you do this. If you need a phone number to appear as sender-id in India, you will need to do this using a virtual number only.

Answer 2

I've been trying to send bulk messages via a GSM modem and found that the GSM network architecture makes clients incapable of sending more than ~10 sms/minute or, allegedly, ~30 sms/minute using GPRS. Exact limits depend on the modem/device, provider and reception. To send more, as was suggested already, you need to look into a (paid) gateway service connected directly to a messaging centre.
