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
OK
AT+CGMR
Revision:1351B03SIM7000E
OK
AT+CREG?
+CREG: 0,0
OK
AT+CFUN?
+CFUN: 1
OK
AT+COPS?
+COPS: 0
OK
AT+CSQ
+CSQ: 99,99
OK
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
