Problem connecting to VZN with EP06

hello, I have a WE826-Q with a verizon SIM. On the initial boot, the SIM was able to connect but even at a TTL of 117 it was still using hotspot data.

However, the bigger issue is that when I tried switching the TTL and rebooting, I am no longer able to connect no matter what I do through the Verizon SIM. I've tried adjusting the TTL and reverting things back but still am not able to connect.

The only error code I see was:
/dev/ttyUSB2 AT+CMGL=4 +CMS ERROR: 303

And the modem was stuck on attempting to connect.

Any thoughts?

Some of these modems do not like reboots. Literally have to unplug them and plug them back into power. (power cycle them)

Yeah sorry that's what I meant, I actually do unplug and plug back in.
I tried this with 2 different active SIMs. It's kind of odd.

The other thing is that when it randomly managed to connect at first, at a TTL of 65 and 117, it was still being detected as hotspot usage.

It seems I am actually having a similar issue to this thread.

EP06 modem, stay trying to connecting, error 303

Except I didn't have a power outage. And it only seems to be an issue with VZN.

I put my Verizon phone sim in a EP06 and it worked fine. But didn't use it allot just tested to make sure modem was working.

According to this you might need a TTL 64 and possibly a VPN.

When I first put in the verizon SIM in, it connected fine but then I changed the TTL and power cycled and it was not able to connect again, even if I reverted settings or reflashed the firmware. ATT/T-Mobile work fine on it. Tried on two different SIMs now

It's possible that the modem somehow got deprogrammed, so try inserting the sim back into your Verizon phone, make a test call and go online, then put the sim back into the router. Make sure the router is powered off before inserting the sim. If that doesn't work, try reflashing the router, and as a last resort the modem too.

The interesting thing is that all of the sudden it actually did work for a bit this morning......then after a reboot AND after power cycling it, it will no longer connect...

Could need custom firewall rules.
Some one helped me to get mine going on verizon with sim in router like this below.

#start TTL rules
iptables -t mangle -I POSTROUTING -o wwan0 -j TTL --ttl-set 117
iptables -t mangle -I PREROUTING -i wwan0 -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
