Hello,
I bought SIM7000E module (link to the product). When I insert SIM, the indicating LED is still blinking 1/s. SIM card has no PIN.
I use this antenna link
If I insert this SIM into another SIM900A module, it works.

Here is some info:
Country: The Czech Republic, Europe
Power supply can supply enough energy

Output of some AT commands:
ATI

SIM7000E R1351

AT+CREG?

+CREG: 0,0

AT+COPS=?

+COPS: (1,"230 03","230 03","23003",9),,(0,1,2,3,4),(0,1,2)

OK

I spend a whole week to figure this out without any success.
Please give me some advice. Thank you :-)

What's the module response to  AT+CPIN?  command ?
+CREG: 0,0 indicates  that the module isn't registered and that MT is not currently searching a new operator to register to.

AT+CPIN?

+CPIN: READY

OK

Hi Lopuch! Did you succeed with the SIM7000 module?
I have the same module (same exact rev. number), and it works form me with a regular Vodafone sim.

Unfortunately I want to use it with a data only sim card and it produces the same symptoms as yours.

If you found any solution, please let me know! Thank you!

Also, if you can try yours with a different sim, it might help!
