How about ”diy“ a phone by using the Crowtail module? This is a new Crowtail- A6 GPRS\/GSM Module, which is use the newest A6 gprs\/gsm chip, A6 is a low-cost but efficient chip. With its ultra-small size, low power consumption and wide operating temperature range, A6 is an ideal solution for M2M applications, for automotive, industrial and PDA, personal tracking, power environmental monitoring, wireless POS, smart metering, and other M2M applications, to provide comprehensive GSM \/ GPRS text messaging, voice and data transmission services. Our module has specially crowtail interface and we design this module for making it work with Arduino\/Crowduino more convenient.
