This product only includes the Quectel EC25 Mini PCle 4G/LTE Module. In order to use this with a Raspberry Pi, you need to use a Base HAT, LTE and GPS/GNSS antennas.


Sixfab SIM

Sixfab SIM is a cellular connectivity solution for connecting your IoT devices with the best global networks. You can activate and use your SIM card in a few minutes, without any contract or commitment.


This Quectel EC25 Mini PCIe is a series of LTE category 4 module adopting standard PCI Express® MiniCard form factor (Mini PCIe). It is optimized specially for M2M and IoT applications and delivers 150Mbps downlink and 50Mbps uplink data rates. The module is 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.

EC25 supports multiple-input multiple-output (MIMO) technology, a cutting-edge antenna technology capable of transmitting multiple data streams on multiple transmitters to multiple receivers. The antennas at each end of the communication circuit are combined to minimize errors and optimize data speed. The module also combines high-speed wireless connectivity with embedded multi-constellation high-sensitivity GNSS receiver. A rich set of Internet protocols, industry-standard interfaces and abundant functionalities (USB drivers for Windows XP, Windows Vista, Windows 7/8/8.1/10, Linux(Raspian), Android/eCall) extend the applicability of the module to a wide range of M2M applications such as an industrial router, industrial PDA, rugged tablet PC, minicomputers like Raspberry Pi, video surveillance and digital signage.

You can easily insert a Mini PCIe module in Base HAT then start using cellular internet with your Raspberry Pi. Both UART and USB communication with modules are available.

EC25 antenna interfaces include a main antenna interface, an Rx-diversity antenna interface which is used to resist the fall of signals caused by high-speed movement and multipath effect and a GNSS antenna interface. The impedance of the antenna port is 50Ω. For cellular connection, you’ll only need to connect an antenna to the main antenna port. To obtain better Rx-sensitivity and signal reception, we’d recommend an additional antenna to Rx-diversity antenna port. Rx-diversity function(ANT_DIV) is enabled by default. All of the antenna connectors are ECT818000117. This is compatible with the Hirose U.FL(known by a variety of names including AMC, UMCC, IPX) connectors. The recommended RF connector is UF.L-R-SMT.

  1. Rated 4 out of 5


    Why we need two antennas? Which two antennas?

    • onur

      As two branches of LTE antenna, the main antenna is responsible for sending and receiving signals and the diversity antenna is only responsible for receiving signals. The multi-antenna technology (MIMO) has the ability to transmit high-speed data and resist interference in the future. So, the better receiving sensitivity, using RX-diversity antenna additional to the main antenna is highly recommended.

    Hi can this only be used with your shield or can I replace my minipci 3G module in Toshiba R600 running Ubuntu? Thanks

    • Saeed

      If the pinout of minipci 3G module in Toshiba is similar to that of Quectel EC25 Mini PCIe 4G/LTE Module, then you may replace it.

  5. Rated 4 out of 5


    Does it need to have antennas to get a better connection? and which type of antennas? if you have a specific part name for that.
    There’s an antenna that comes in the same page of the 3G/4G-LTE shield, but I read about it , and it only supports 2G .

    Hi All,
    Can this module work for dual apn public and private together. Can i do two separate configuration for ppp0 and ppp1 for a single module? . my sim supports dual apn.

    • onur

      The Module supports single APN and thus single PPP connection.

    Just got my self a EC25 Mini PCIe with a Raspberry Pi 3G-4G/LTE Base Shield V2. No problem communicate with through USB. But no response from the UART via the Rpi pin header what so ever (have tried connecting a terminal directly to the Rpi pin header UART pins and that works)

    Any ideas on how to get the UART work for AT commands?


    • Saeed

      Do you have bridged the UART RESISTOR pads available below the shield?

    Bought the EC25-V for Verizon in the US. When I try to activate the IMEI with Verizon or several other carriers, they say the IMEI cannot be activated. It appears this module does not work in the US. Are there any other options?

    Is the Quectel EC25 Mini PCIe work in Mexico?
    Is the Quectel EC25 Mini PCIe support 3G network too?


    • Saeed


      Yes, EC25-AU variant works in Latin America.
      Yes, The module is 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.

    What are the operating temperature range, and storage temperature range for EC25 ?
    does it cover entire US & EU

    • ensar


      Temperature Range:
      Operation temperature range: -35°C ~ +75°C)(1)
      Extended temperature range: -40°C ~ +80°C)(2)

      1) Within operating temperature range, the module is 3GPP compliant.
      2) Within extended temperature range, the module remains the ability to establish and maintain a
      voice, SMS, data transmission, emergency call, etc. There is no unrecoverable malfunction; there are
      also no effects on radio spectrum and no harm to radio network. Only one or more parameters like
      Pout might reduce in their value and exceed the specified tolerances. When the temperature returns
      to normal operating temperature levels, the module is compliant with 3GPP specification again.

      Yes, it does.

    is there any prediction when the EG25-G (global version) will be in stock again?

    Tim Gardner

    It worked great right away using USB ECM mode setup. I was surprised by the speed. It is a great 4G connection for Raspberry Pi for project with Cellular connection to internet. Or for IoT use also. Connecting over UART will be slower but will work but is tricky to get working. There is community help there for that and I posted my setup process. I would really recommend these. The build quality of the Hat is great.
