- Q
- Hi,
  
  I have few questions for this product,
  1. Will this product works anywhere in the world(USA)?
  2. Do I need to have any micro controllers to be attached to this device before connecting to PC(computer) to send and receive sms through computer?
  3. Do you have the documentation available to configure and make this work to send and receive sms?

- The GSM/GPRS Modem-RS232, from rhydoLABZ, is built with Quad Band GSM/GPRS engine- SIM900, works on frequencies 850/ 900/ 1800/ 1900 MHz. So it will work anywhere in the world where the GSM frequency band is among one of these 4 frequencies.
  
  You need not use a microcontroller for direct communication of this device with PC. Since it have a DB9 connector(RS232 out), device can directly communicate with PC through its serial port with the help of DB9 cable. If you use USB port you should need a level converter.
