A New Low-Cost Module: SIM900A GSM/GPRS Minimum System Module

Itead Studio will launch a new low-cost module SIM900A GSM/GPRS minimum system module. As you may know, SIM900 is a quad band modem being able to operate in 850,900,1800,1900 MHz bands, while SIM900A is a dual band GSM modem being able to operate only in 900,1800 MHz bands. That is to say, SIM900A GSM/GPRS minimum system module can be used in the countries where triple band and quad band exists, but the signal may be lower, as it cannot receive signals of another two bands. In the following regions where dual band exists, we recommend to use SIM900A GSM/GPRS minimum system module to reduce costs.
