    I’ve been unable to make it work when it is directly plugged on my UNO clone. However it works perfectly when I use the Rx, Tx and Gnd pins from the UART under the Status and NetLight LEDs (as shown in picture). For my project it’s okay, but could be a problem if you want the shield to be stacked. In addition it’s clearly not brand new... but hey, at this price point I can’t complain since it’s working!

    Like on the description, delivery was fast, i am happy about it. I did not yet try it. Just a pity there is not the male pins to plug the shield directly on the arduino

    The SIM module is good, to send sms and to call. :)

    Arrived on time, in good conditions. SIM card adapters included too (unexpected). Not tested yet.

    Well it came very fast,like 7-8 working days. (location Greece) The package was in a good condition and the shield itself also. I havent tested it yet but I dont see any damage.

    Recibido hoy después de casi 1 mes con envio priority, todavia no lo he probado dado que se necesita una pila CR1220 (En cualquier tienda creo que las encuentras) tiene buena calidad veremos que tal funciona.

    the DC-DC converter MIC29302WU on the board has 5 pins and uses about 7mA in standby. I cut all traces to pin 1 and 2 and connected pin 2 to RAW and pin 1 to an unused port. so i can shut down the DC-DC converter completely. HIGH on pin1: MIC29302WU working LOW on pin1: MIC29302WU shut down, no current use! best wishes from austria

    Works perfect. Writing a working sketch in arduino is a little bit more difficult because libraries found online doesn't work with this module. You must make your own library or sketch from beginning.
