Send sms over GPRS connection

RouterOS Wireless Networking
1

Hello!

I have RB493G and Huawei E1752 USB modem, i can connect via GPRS and send sms, but i faced a problem, while router is connected via GPRS connection i cant send sms, if its not connected sms sends successfully.
From terminal:
failure: port’s channel is already in use

Is there any way to use GPRS connection and sms simoultaniously?

Thank you in advance.

2 options come to my mind.

  1. use GPRS modem with more channels
  2. write a script where you disable gprs connection, send sms, then reconnect to gprs (if this is an option at all in your case)

Some modems have multiple channels. This way the GPRS data connection uses a channel, while Info and SMS use another channel. Check the specs of your modem or simply use trial and error until you manage to get both working.

Some older modems only have a single channel, so you will have to use the script suggestion.
