Installation of T-Mobile SMS connector

T-Mobile SMS connector installation is described here. This driver is different from common GSM modules and it needs different configuration data. You must have T-Mobile SMS Connect service active before installation. After service activation IPsec tunnel will be established for SMSC connection (server-server mode), so you'll need cooperation with your network admin to create tunnel.

Select T-Mobile SMS connector from driver list, then this dialog is displayed:

SMS center address and Port - IP address and port, which line driver uses for communication. That address must be reachable before installation (tunnel into T-Mobile must be established and functional) - you must be able to connect to given address and port using telnet.
If telnet reports "Connect failed", tunnel is not functional.
LAID - user name (Large Account ID) for logging on to SMS Connect service
Pasword - password for logging on to SMS Connect service
Sender number - your MSISDN number (will be used as a sender's number for your SMS, has form +420 736 3xx xxx)

All these information you receive from T-Mobile company.

Speed of SMS sending depends on MobilChange version: Standard version allows max. throughput 1 SMS/ s, Enterprise version has no speed limit. These information apply to MobilChange 4.6.22 and higher.
