Work as a voice broadcast

Use our voice call software, upload call list and audio file. Our terminal will dial call list one by one. And play voice once the phone call gets through.

Work as an SMS modem pool

Our wireless gateway terminal is with SMS deliver voice call software and SMS caster bulk SMS software. Each sim card can send 900 messages every hour.


 STK mobile recharge and check balance

STK consists of a set of commands programmed into the SIM which defines how the SIM should interact directly with the outside world and initiates commands independently of the handset and the network. This enables the SIM to build up an interactive exchange between a network application and the end-user and access, or control access to, the network. The SIM also gives commands to the handset such as displaying menus and asking for user input.

IMEI change for avoiding sim block

SIM card will be blocked by the carrier if it calls continuously. Our telemarketing auto dialer wireless gateway can reduce block through changing IMEI.  And it is helpful when it works with  IP PABX and VOIP gateway for call termination call traffic.
