Did you connect the sim card as is showed here?

Hi,

Please share with us some images of the 4G module in which we can see the sim card connected to the board and another one of the sim card connector without the sim card. You can use dropbox, google drive, etc to share the images.

Hi,

We think that the sim card doesn't touch the sim card connector properly because it's cut. Could you try using a SIM card adapter that has plastic on top to prevent the SIM card from leaving the adapter?

Anyway, please send us some images in which we can see detailed the pads of the card socket.

Hi,

What API version are you using to upload the code to the node? Did you try with the latest API v043?
http://www.libelium.com/development/was ... lications/

Do you have another 4G module? Does it work using the same sim card?

Could you please check if the pads of the sim card connector are solder properly to the board? We can't see it well in the images. Sometimes, we have found it isn't soldered properly and therefore the sim card isn't detected.

Regards

Hello,

I have tried using the latest API v043. the same error is shown.

I don't have another 4G module.

Regarding the Simcard connector on checking it seems the legs are soldered.
