Sim7000E "Fail to Attach service"

HI,
I've been successfully using sim800 with a sim card from keepgo in Canada. At first I've ordered sim7000C then I've been advised by DFRobot to use the sim7000E instead. I've received the new 7000E but can't make it work.
First question I don't see where I can put my apn settings in example codes provided with DFrobot library
Working well on DFrobot sim800, I've tried the tinygsm lib with the sim7000E https://github.com/vshymanskyy/TinyGSM/ ... Client.ino
I get stuck at "fail attaching service"
Even using http example, I get this from serial monitor
"Turn ON SIM7000......
Turn ON !
Set baud rate......
Set baud rate:19200
Check SIM card......
SIM card READY
Set net mode......
Set GPRS mode
Get signal quality......
signalStrength =10
Attaching service......
Fail to Attach service
Fail to Attach service"
Yet the net led is flashing every 3 secondes and as I get a signal strengh, it seems a network is available...
What's really weird is I get this from serial, only by mistaking rx(8) tx(7) pins. If I put correct values :
#define PIN_TX 8
#define PIN_RX 7
Then I get stuck at "Turn ON SIM7000......"!
Thanks for your help.
Best,
Franck


Then changed the sketch from attacthService to attachService and did the same in all the files in the library.
It then worked perfectly, ONCE. Now im back to failing to attach service. any ideas? when the sketch worked perfectly I reopened the serial window to double check, and it stopped working again

Both "internet" and "Telstra.internet" don't work
Using AT Command Tester, I Can ping google no worries. This would confirm it is definitely a library issue

if(check_send_cmd("AT+CSTT=\"cmnet\"\r\n","OK")){ delay(100); }else{ return false; }
In my case, in Poland for Orange network, I needed to change to "internet" and now it works perfectly.
Good luck!

I have also a similiar problem with the attach function,the net light is blinking and the signal strength is working. Using the at command "AT+COPS" it cant detect the network of the sim. But the sample code always fail when it uses the function sim7000.attacthService().
Can anyone help?

I have been using the same way as you have informed but still the service fails to attach.
even the net light is blinking and the signal strength is indicated to be 14.
What I might have been doing wrong.
Please guide me in this repect.
Regards
