SIM7000E Shield: BME280 works, SIM7000E does not

Hi,

I can talk to the BME280, but the SIM7000E doesn't seem to init. Must I have a SIM card inserted? If so, do I need a special LTE-M SIM card?

Thanks!
2020-01-13 11:40:41 Yes, the switch is connected as TX 8 , RX 7.
What could be the reason that SIM7000 is not turning on.

2020-01-08 12:51:23 Hi there,

The code is definitely updated now but instead of errors my serial monitors say Turning on SIM7000...
and that's it!
it doesn't go anywhere ahead of this message.But with the BME sensor code that works totally fine.
Can you please guide me what might be the problem.

Regards

2020-01-01 13:10:49 Im having the same problem. It looks like the library has been updated but the DFRobot wiki example has not. Pretty poor effort at support and nobody answered your question. userHeadPic sjowett63
2019-02-16 01:48:33 I was trying to test the SIM7000E Arduino NB-IoT/LTE/GPRS/GPS Expansion Shield GPRS shield with the demo code that DFR has given in there wiki page…I installed the said library(file:///C:/Users/Kishor/Downloads/DFRobot_SIM7000-master.zip). But many errors while trying to compile for Arduino Uno. I even had to install DFRobot_SIM Library …Still following errors!
Please help...

I am here by copying the error codes…(Sorry just copied from Arduino IDE)
