WG1608-V2 + Quectel EM12-G (SOLVED)

[charlesrg]

I'm testing a EM12-G with vzwinternet however on the General Information page the Provider states: "Connecting".

I can see the Modem/SIM info like IMEI, SIM IMSI, ICCID, Phone Number

But there is no Signal Info or Cell Info.

I've read the Quectel AT commands and tried to query a couple things.

Code: Select all

#Operator Info
AT+COPS?
+COPS: 0

#Network Info
AT+QNWINFO
+QNWINFO: No Service
OK

#ISP Name
AT+QSPN
ERROR

Am I expecting too much to connect the modem with a post paid sim with data plan and expect it to just work ?

Is there a troubleshooting guide that I could refer to get me up to speed ? Just reading the AT command set didn't enlighten me as I hoped.

[charlesrg]

I tried issuing a:

Code: Select all

AT+CFUN=1,1

but it didn't help.


But still shows connecting. Debug shows:

Hello,
Try this on custom firewall.

#start TTL rules
iptables -t mangle -I POSTROUTING -j TTL --ttl-set 117
iptables -t mangle -I PREROUTING -j TTL --ttl-set 117
ip6tables -t mangle -A POSTROUTING -o wwan0 -j HL --hl-set 117
ip6tables -t mangle -I PREROUTING -i wwan0 -j HL --hl-set 117
#end TTL rules

Also try these at commands
AT+QMBNCFG="AutoSel",0 (stop Autoselect config on sim detection)
AT+QMBNCFG="Deactivate" (disable MBN config)
AT+CFUN=1,1 (reboot the modem)

[charlesrg]

Still didn't work, here is some debug info with identification numbers replaced with XXX.
The only line I see an error is: AT+CPBR=? which in Quectel manual says is to read phonebook entries. The Sim should have no entries so it should be ok to fail.

I think the issue was Verizon not liking my modem. I popped a ATT sim and changed the profile to "broadband" and it worked.

Wondering what's the best way to find when a carrier rejects you instead of just keep trying. Wish there was a AT command to find out.

[gscheb]

Yes Verizon can be rough for sure.

[charlesrg]

That was exactly the case, used another SIM and it was back. Now I got it to work with Verizon and ATT.
Thank you guys.

Thank you guys.

What did you end up doing to get it working?

[shrecewa]

I'm also curious how you got it to work?

[charlesrg]

I put it back the simcard onto the phone so verizon would reactivate it. They didn't like SIM in the Quectel modem.

Thank you guys.

So what did you do to get it working on Verizon?

[punkguy00017]

He said he put the SIM card back in the phone so verizon reactivates his sim

[Acme182]

This didn’t work for me. I put the sim in my phone and it worked, but when I put my phone sim in my router, it didn’t work. I put the router sim back in the router and it didn’t work either. So the sim works in my phone, but not in the router. I’m new to this but it seems they are blocking my router

I reset the router firmware and it fixed it.
