valdez Youneed at least 2A, and you provided just 0.2A (200mA is 0.2A) :-)

Hello, Thank you for the delivery. It arrived on time. Unfortunately, it was dead on arrival. I followed the instructions, the SIM mounted was unlocked, the module was powered by a 9V~200mA converter, but I could not connect to it. The power led is ON and that is it. The sim does not respond to any commands not with 19200 Baud or anything else.

it worked out of the box! You can use it either via USB or UART interface, it's quite fast and easily configurable using the codes listed in the user manual linked in description above.

the article arrived earlier than expected, but I was not able to make it work. I have wired it as described but it is not responding to any text command sent to it. It would be nice if you could provide at least a manual or instructions on how to drive it.
