Still a good product
I use this module for the last 3 years. Still very good and stable. One problem detected! Working above 50 degrees celcius some of the modules got problems and didn´t recovered. Some others recovered and become ok again whem temperature goes lower! In datasheet the acceptable working temperature should be higher than 50 degrees... I will continue using this module.

Very good and very stable
I´ve tried many similar products but the ITEAD SIM900 GPRS/GSM Module is the better one. Very stable and veru robust, never give me problems so far. I will increase it´s use in my projects.
