Mesa 2 will not activate with Verizon
12 Feb 2019
If you are not able to activate a Mesa 2 unit with Verizon Wireless, some possible causes and solutions are as follows.
You may need to uninstall the default 4836 drivers and then install the previous 4775 drivers as detailed at the bottom of the following web page.
As mentioned in the user guide (manual), the IMEI number can be found under Start > Settings > Network & Internet > Cellular > Advanced Options. If Verizon states that the IMEI number is not registered in their system, please verify the 15 digit number with them. If needed, you can contact email@example.com with the serial number and IMEI number to have us register the unit with Verizon.
Make sure the SIM card is properly inserted. A Micro SIM card must be used and not a Nano SIM in a Micro adapter. Adding a pull tab to the SIM card is recommended for future removal. Once the card is inserted, perform a Restart.
The SIM card must have an active "laptop modem" data plan. Consumer smartphone or tablet data plans may not work with the Mesa 2.
You may need to perform a Hard Reset by saving data (if needed), closing all running apps, performing a full Shut Down or Power Off (wait until red LED turns off), remove external power supply (wall charger), hold the hardware Power button for 20 seconds (red LED will stop flashing rapidly while still holding), release and wait a few seconds, attach external power, briefly press the Power button again, wait for the unit to complete boot, and then check the cellular modem status.
Mesa 2 units that have "Original OS Version: 18323" (as can be viewed under Device Info) can be changed to work with Verizon as described in the following document.
As briefly mentioned above, these specific units were shipped with the Sierra Wireless AirPrime 74xx cellular modem "UNIFIED" version 4836 Generic driver. This driver combines the previously separate drivers, but removes the automatic network detection for non-GSM carriers such as Verizon. Carrier specific firmware must be manually installed for the cell modem instead. Or it may be simpler to just install the previous separate drivers which provide automatic network detection for carriers such as Verizon. Once the network has been detected, the newer driver can be installed again if desired. Both the previous drivers and new driver are provided at the following web link.
Mesa 2 units with Microsoft Windows 10 which were originally purchased prior to official certification in July 2016 were not registered with Verizon. Similarly, Mesa 2 units with Android 5.1 AOSP which were originally purchased prior to official certification in January 2018 were not registered with Verizon. You can contact firstname.lastname@example.org with the serial number to have us register the unit with Verizon. This is as described at the following web links.
