Lack of material for network adapter

I can't get this thing to work. I know it reads the SIM card but won't connect to the network even from a 2.4 amp USB charger. The same blink in a second. If anyone was able to connect to USA ATT it would be nice to know. The most disappointing thing is that since it's a single device, if it's really a power issue, I expect it to work without any additional hardware. And even then, with all the components built into the board, I don't know where to connect more power without risking the…

The best debugging tool for W10

I had to research the drivers for W10 known as cm45. The manufacturer must set a link if he wants to sell more. What can I say? This is a mobile for terminal debugging. Easy to program in JS or C#. Use Tallow for cheap sim cards. I will buy more. I just finished 3D printing the case. Thinking about it, don't buy as there will be more for me :) Great product!

Pros
  • Great price
Cons
  • Big and bulky

ZIP Code 53213 = No Signal

I live in Milwaukee, not in a big city but surrounded by LTE towers. This thing is completely in the dark. No signal. AT+CSQ returns +CSQ: 0.0. A text document in Chinese was sent to me in response to my return request. This document shows the fact that only 2G networks are supported. "Connect the 2.4GHz GSM antenna to the module, insert a SIM card (Note: support Micro/Nano card, support 2G/3G/4G card from China Mobile or China Unicom -Mobile phone), but does not support 3G/4G network, does not
