Kingdom-tech is an official distributor of M2M products of Quectel, especially communication modules such as 2G,3G, 4G and NB-IoT . The company is engaged in not only selling products of represented brands, but also everything necessary for their integration, such as antennas, connectors, cables etc. Every business is with technical support after sales.
Quectel EC25 is a series of LTE Cat 4 module optimized specially for M2M and IoT applications. Adopting the 3GPP Rel. 11 LTE technology, it delivers 150Mbps downlink and 50Mbps uplink data rates. Designed in the compact and unified form factor, EC25 is compatible with Quectel UMTS/HSPA+ UC20 module and multi-mode LTE EC20/EC21 module, which allows for flexible migration among them in design and manufacturing.
EC25 contains 10 variants: EC25-E, EC25-EU, EC25-EC, EC25-A, EC25-V, EC25-AF, EC25-AU, EC25-AUT, EC25-AUTL and EC25-J. This makes it backward-compatible with existing EDGE and GSM/GPRS networks, ensuring that it can be connected even in remote areas devoid of 4G or 3G coverage.
EC25 supports Qualcomm® IZat™ location technology Gen8C Lite (GPS, GLONASS, BeiDou, Galileo and QZSS). The integrated GNSS greatly simplifies product design, and provides quicker, more accurate and more dependable positioning.
A rich set of Internet protocols, industry-standard interfaces and abundant functionalities (USB serial drivers for Windows 7/8/8.1/10, Linux, Android/eCall*) extend the applicability of the module to a wide range of M2M and IoT applications such as industrial router, industrial PDA, rugged tablet PC, video surveillance, and digital signage.

Q. 1: How much the transportation freight of samples?
The freight depends on the weight and packing size and destination from here to your location.
Q.2. What's your advantages?
Q.3:What is the maximum time that the module responds OK after executing ATH to hang off a call?
According to the 3GPP standard, the maximum time that the module responds OK after executing ATH to hang off a call is 90seconds. You can set the proper timeout of ATH in the MCU program based on the maximum time.
