Hi
Currently running MODEM SIM7600 with Tmobile sim card, its register on the network but no data, I checked APN several times and all is good cant established PPP
Is there anyway I can manually set IMEI of the SIM7600 modem, i believe this is likely the issue why it cant get data on Tmobile network?
Your help is highly appreciated
Thanks
This the status of the modem
Thanks
The IMEI is a part of the modem device itself, and I don't think it should be changed.
That said, supposedly the AT command "AT+SIMEI=xxx" command will change the IMEI. Never done it, so not sure if it is persistent. I suggest writing down the existing IMEI number before messing with change it.
More likely the SIM card is not registered or activated for data service, or the APN/user/pass is incorrect, or some other compatibility issue.

I appreciate your help on this, do you happen to know what command I need to type in shell to know the current modem IMEI? I have it installed in the car in a hidden area would take me couple of hours to get it out trying to avoid that if this can be retrieved from the shell
Thanks

I would say to try the sim card on a phone and see if data is activated. If you know how to send AT commands to modem. I am interested. I'm new using OVMS.
If you know how to send AT commands, you can try to check some ones:
AT+CGDCONT?
should return something like:
+CGDCONT:1, <Tmobile internet apn>
you can also try AT+CGACT?;
should return +CGACT:1,1 meaning that apn context 1 is activated.
if it returns +CGACT:1,0 it means that modem internet apn is not activated.
In any cases, you can send me the returns of the AT commands. I can help you on understanding the values. These AT commands are part of the 3GPP standard.
Here are the commands on my OVMS module
OVMS#cellular cmd AT+CGDCONT?
+CGDCONT: 1,"IP","sl2sfr","0.0.0.0",0,0,0,0
OK
OVMS#cellular cmd AT+CGACT?
+CGACT: 1,1
OK
