      Wondering whether anyone’s used the new LTEBee modem with a Verizon SIM. If so, what APN did you use? So far, I’ve tried “-” and “vzwinternet”, which worked with this SIM in a Digi XBee3 modem, but not the EnviroDIY LTEBee.

      Thanks,
      Matt

      Hmm, so maybe no one has tried Verizon with the new modem yet. SIMCom claims that chip supports Verizon, but (suspiciously?) they don’t have a Verizon Certification document available for download, as they do for other carriers. And they list all their supposedly supported carriers under a heading labeled “Certifications(plan)”, which makes me wonder if it’s not been certified by Verizon yet.

      We have 4 stations in the field running via Verizon on the Digi modem, so I hope this gets resolved soon. It’s nice to have options for multiple carriers when you operate stations across the country.

      These modules are new enough that I think everyone who has bought one so far is using the same Hologram SIM cards that we use in all of ours.  I’ve deployed over 50 of them in the past couple months with Hologram cards, and according to our dashboard page that shows connection information, they are active on all the major carriers including Verizon, AT&T, T-Mobile, and Sprint.  I haven’t used a specific Verizon SIM card, but I see no reason why it wouldn’t work.

      Ok, that’s very interesting. It sounds like the LTEBee with a Hologram SIM has been using what it sees as the ‘best’ carrier for a given connection. The Digi modems would never do that for us in areas where Verizon was the only viable option, so we had to get Verizon-branded SIMs for those cases.

      FWIW, I asked SIMCom about their Verizon certification, and this is their reply:

      We are in the process of getting the certification.  All testing has been completed and we are just needing to schedule and official drive test with Verizon.  After this we expect to have certification shortly after.  I am estimating we will have it completed late December or January.

      The SIMCom 7080G modem chip upon which the EnviroDIY LTE Bee is built did not have Verizon certification until early August. Once they notified me, I asked SIMCom support what APN setting to use for Verizon, and this was their response:

      Set you APN as follows:

      at+cgdcont=1,”ipv4v6”,””
      at+cgdcont=2,”ipv4v6”,”vzwadmin”
      at+cgdcont=3,”ipv4v6”,”vzwinternet”

      We were able to get an EnviroDIY LTE Bee to connect to Verizon, using ModularSensors, by setting the apn to an empty string, e.g.:

      Hopefully this helps anyone else who needs Verizon coverage with these newer modems.
      Best,
      Matt

      @mbarney, thanks for the settings.   What was the sim supplier that you used – a Verizon direct, or an MNVO like REVX.

      I did get an email earlier this week from SimCom that there 7080G was now certified by Verizon, so good to know it works 🙂

      Hi @neilh20, I believe the SIM we used was a RevX.

      @mbarney, do you know if the REVX plan/sim card you had success with is the CATM version (50mb for $5) or the 4G version (10 mb for &12)? With the new modems I have not been able to register on the network (cereg 0,3) using the 4G plan and sim that worked for a couple years with the old xbee modem.


      @shicks
      ,  RevX systems technical support has indicated that the IMEIs associated with the new LTEBee modems are not Verizon certified.

      Looking at this line, the current IMEI is not appearing as Verizon End Certified. Verizon rejects registration of device’s that are not Certified through the upload process to the Verizon Device Management Database (DMD). This is typically done by the manufacturer unless you have an Open Development application completed with Verizon.

      If you believe this device to be certified, please contact the manufacturer and request that they re-upload the device IMEI’s to Verizon as they are not valid at this time.

      From what I understand, SimCom has received certification for the module itself on Verizon, but once integrated into a device (like the LTEBee) the entire device must be certified a second time before Verizon will allow it to register on their network. Do the new LTEBee modems have this end certification with Verizon, and can their IMEIs be “uploaded” to Verizon?

      End device certification for an open source DIY project like this is nearly impossible, since there’s an infinite number of combinations that users can configure their station with various equipment, accessories, antennas, not to mention all the ways they can change the actual code running on the main processor board.  That’s why we try to use modular telemetry devices that are certified by most carriers, however Verizon has always been picky about allowing DIY devices on their networks.  I’m unfamiliar with REVX, but I know other people have had success using other non-certified (and non-EnviroDIY) devices with Verizon networks with other sim card providers.

      @jamesbailey I’ll check with my colleague to find out exactly which SIM he used for the test; he’s in the field for a few days. My test code is based on https://github.com/EnviroDIY/ModularSensors/blob/master/examples/DRWI_SIM7080LTE/DRWI_SIM7080LTE.ino, and the only modem-related code change I made was to the APN.

      I’ve confirmed that the Verizon SIM we used was this one, from NimbeLink:
