Hello,

Does anyone know why this customer is not getting a response from Verizon , or how long it takes? Thank you.

It could be the code still needs to be activated but not sure. I would probably check with Mason or Cullen (PM) I know Mason may not be available though.

Hi @jradtke, welcome to the forum.

Which Sierra Wireless GL7500 model did you order?

Did you get the Verizon SIM card with the kit, or from Verizon directly, or thru a virtual mobile operator (RevX Systems, Hologram, etc)?

Regards,

Direct from Verizon…

after 9 days and many hours talking with their support people they have no clue

I found below reference on configuring PDP in Sierra Wireless forum on GL7500 and Verizon https://forum.sierrawireless.com/t/gl7500-data-modem-setup/16186/3

Thanks,

But…Yes that was all done/tried a week ago…

Signal is Excellent

The device connects to Verizon

AT+CGACT 1,3 activate PDP 3

AT+CGATT=1 attach

Then I get an IP address

unable to send SMS

AT+CREG - Register Denied

Hi @jradtke,
I am checking with our Product team to try and get additional insight from Sierra Wireless and will let you know what I find out.

Thanks for the help

Hi @jradtke,
Can you email me your IMEI number and a picture of the label on the GL7500? My email address is scott.raeker@digikey.com .

Thanks,

IMEI 356815080112551

Can you print out the results of the following commands:

AT+CGDCONT?
AT+CGDSCONT?

Thanks.

Attached

Please try the following commands:

AT+CGDCONT=1,”IPV6”,”VZIMS”,””

AT+CGACT=1,1

Thanks.

1st … should be V Z W I M S

at+cgdcont=1,“IPV6”,“vzwims”,“0.0.0.0”,0,0

Also PDP change was locked per AT+HBHV?

so I unlocked it

Then made the change

Then looked at PDP list …the change took ok

AT+CGACT=1,1 returned - error

My understanding is PDP 1 is for cell carrier use only

After rebooting the device

AT+CFUN=16

PDP 1 reverted back to

the string before the change was made

Thank You all for your help …while I still have Register Denied … I am able to send SMS at this time
