    I am attempting to establish a PPP connection using a V2 shield with the EC25-v PCI-e module. I have made all the proper connections with USB and shield headers, antennas, and an activated Verizon SIM card. I have tested the SIM in a few different phones, and it is functioning properly. When I run the connection command, sudo pppd call gprs, I see the following messages. The signal does not appear to be strong, but should be adequate to create a connection. I am concerned that the device is not properly authenticating with the Verizon Network, but I am not sure how to verify or fix this.

    Any insight is appreciated.

    @sean I have the same setup on Verizon. I’m getting the same result – modem hangup and connection terminated.

    I also saw the “No auth is possible”, and questioned whether my SIM card was properly activated. When I tried it on my cell I saw “Your new Verizon Wireless phone is now active.” When I viewed my account info on verizonwireless.com I see a new device but now tied to my cell’s IMEI. Not sure if that even matters, maybe it doesn’t. But I plan to take it in the the store tomorrow to see if there is a problem with the SIM.

    I have tried different variations of the APN:
    internet
    INTERNET
    vzwinternet

    https://www.verizonwireless.com/support/knowledge-base-55863/

    Verizon Wireless APN Settings

    I am using a PI 3B with (onboard wifi/bluetooth) and Rasbian STRETCH.

    Any help from Sixfab would be appreciated.

    Hi Greg (and anyone else lurking on these forums).

    I also tried some variants of Verizon on the pppd setup script to no avail. I then called Verizon Customer Support and shockingly got on the phone with a representative very quickly who was relatively helpful. It appears that Verizon’s network servers will reject authentication from a device they don’t recognize. This explains why I can use this SIM card in the phone I activated the card with and with any other Verizon activated phone. The servers will authenticate any device with a registered IMEI number in their system,. The representative told me that if the EC25 module isn’t registered with Verizon, it won’t connect. He tried to activate the new device with their system, but the IMEI number isn’t in their database. This makes sense, since it isn’t associated with any devices they sell.

    I am looking into how to register the EC25-V with my account so I can get it to connect, and will post here if I discover anything else useful.

    If anyone has any further relevant information to share, please do.

    -Sean

    @sean Update on my progress.

    I took the device and SIM in to the Verizon shop yesterday and the guy said let’s try a different kind of SIM. With the new card I was able to get further in the script, I’m not getting the modem hang up anymore. It appears the script is running. I asked him what the differences in the SIM cards, but he really didn’t know. All he told me was it has “Micro 3FF-A” on the card.

    I went back to my lab and was testing, but still getting +CSQ: 99,99 (not known or not detectable http://m2msupport.net/m2msupport/atcsq-signal-quality/). I only get about 1 bar on my cell outside of town, so I went to an area that I get full bars on my cell and was getting +CSQ: 19,99 now (Good) from the EC25-V modem.

    I opened the browser and played around on the Internet for about an hour without any issues. The speed was pretty decent for a cell connection too.

    In conclusion, I don’t know if it was the SIM or not, but it definitely was a signal strength issue.

    Hope that helps.

    Greg,

    Thanks for the update.

    When you got the new SIM card for the modem, did you activate it ona normal consumer account? I have spoken with a number of verizon representatives and none of them have been able to find the modem in their system, so they have not been able to recommend the proper kind of account to use.

    Sean:
    Yes, they added it to my existing consumer account which already had an iPhone and Samsung phones with a data plan on it. I did this through an authorized Verizon reseller store and not through a corporate store. My original account was setup by corporate though, but when I went into that location, they told me they cannot handle BYOD SIMs. I thought that was strange, but they directed me to a reseller location. The device shows up now under my account.

    Hope that helps.

    So, far it has been working well, but only in areas with strong signals.

    I’ve been having this same issue and haven’t found the cause yet. Has anyone got it working with AT&T, and if so, with what APN? I have a good signal strength with the two antennas from sixfab, so I know it’s not that.

    Sorry for the duplicate post, I didn’t see my first one show up. I found out the solution for my case, and maybe others who use AT&T. I found the APN pta worked for me.
