SIM card not recognized with EP06-E ("+CME ERROR: SIM not inserted")

Hey Sixfab community!

Coming to you in hope to get some assistance/solution in regards to this issue I keep running into…

First off, here’s what my setup is like:

  • Raspberry Pi 4 (Model B Rev 1.2)
  • Sixfab 3G/4G&LTE Base Hat
  • Quectel EP06-E (EP06ELAR03A06M4G)

Basically, just trying to set up Internet uplink by following the “QMI Interface Internet Connection Setup Using Sixfab Shield/HAT” but USIM is not recognized despite being inserted correctly.

AT+CPIN?” will always return “+CME ERROR: SIM not inserted”…

As an attempt to prove this issue may not be related to the Quectel EP06-E module, I also have a Telit LE910EU-V2 with which I am successfully able to connect to the Internet by following the “Setting up the PPP connection for Sixfab Shield/HAT” guide.

Pictures of my setup with both Telit and Quectel cards below…

As you will see, one of the SIM card holding pin (in the middle to be precise) is missing but this should not affect usage or recognizability since everything works perfectly fine with the Telit module… This seems to be specifically related to Quectel and/or the QMI interfacing script.

Any idea/lead as to how I could solve this?

Many thanks in advance!

J.

Hello @j051y,

Your Base HAT’s SIM holder is damaged, there is a pin missing
image

You will need to change the SIM holder(if you can) or get a new HAT.

Hey @saeed, thanks for getting back to me!

Can you shed some light as to how the SIM card is recognized with the Telit module although the holder is damaged?

How is it that it could work with one module and not the other?

Thanks again!
