Works a treat
Excellent device, comes with good instructions and communication with seller is A1.
I had Trouble with getting the right SIM but once found works well. Signal was a little low in the area, changed to Lebara mobile with it using the Vodafone network. EE was intermittent worked only when weather was moist.
Vodafone didn't work at all, and O2 was the same just a tone saying unrecognized number. Orange used EE network and didn't use.
Very clean circuit layout and isolated with hot melt glue a bit fragile so install SIM carefully and take care to place the wires neatly back when replacing the top.
Once working the device picks up after two rings. Did not use the device in alert mode where you send a text message to activate. Four 1s on and four 0s off.
