پیشنهاد میکنم مقاله گذر از 2G به 3G را هم حتما جهت انتخاب این ماژول مطالعه بفرمائید.
همچنین میتوان فوت پرینت را به گونه ای طراحی کرد همزمان برای دو ماژول UC20 و M10 مناسب باشد. 
Quectel UC20 is a powerful UMTS/HSPA+ module offering maximally 14.4Mbps downlink and 5.76Mbps uplink data rates. The module is designed to provide customers with global network coverage on the connectivity of UMTS/HSPA+, and it is also fully backward compatible with the existing EDGE and GSM/GPRS networks.
Its compact profile of 29.0mm × 32.0mm × 2.5mm in cost optimized SMT form factor and high integration level enables integrators and developers to easily design their applications and truly benefit from the module’s multi-functionality, low power consumption and mechanical intensity. Its advanced LCC package is ideally suited for large-scale manufacturing which has strict requirements for cost and efficiency.
A rich set of Internet protocols, industry-standard interfaces and abundant functions (such as USB serial drivers for Windows 7/8/8.1/10, Windows CE, Linux, Android/eCall/GNSS) extend the applicability of the module to a wide range of M2M applications such as automotive applications, smart metering, tracking systems, security solutions, routers, wireless POS terminals, mobile computing devices, PDAs and tablet PCs.
Key Benefits
- Worldwide UMTS/HSPA+ and GSM/GPRS/EDGE coverage
- GNSS receiver available for applications requiring fast and accurate fixes in any location
- High-quality data and image transmission even in harsh environmen
- Primary and diversity receive paths are designed for equivalent noise-figure performance
- Robust mounting and interfaces
- Fast time-to-market: reference designs, evaluation tools and timely technical support minimize design-in time and development efforts

سلام در مناطقی که 3g وجود نداره ماژول میتونه به 2g سوییچ کنه؟؟ یعنی کلا 2g ساپورت میشه؟
Sisoog OS –
سلام بله ساپورت میکنه و بصورت اتوماتیک سوئیج میکنه
حتی شما میتونید برخی از باندها را فعال و یا غیرفعال هم کنید
