SIM7000G with T Mobile NB IoT ?? #78

Open mpablo135 opened 5 years ago

mpablo135 commented 5 years ago

I am planning to get a SIM7000G shield and use with T Mobile Nb IoT network. Has any body tested to verify that SIM7000G shield works with T Mobile NB IoT and with what brand simcard ?

Thanks

Check out https://www.twilio.com/. They are partnered with T-Moble for IoT solutions.

I just noticed my Hologram.io SIM is connected to T-Mobile via 2G.

robbiet480 commented 4 years ago

FYI, I bought a SIM7000G and tried to get it connected. It appears that T-Mobile no longer allows uncertified devices onto their network. At best, I got a 0,3 response to CGREG which means access explictly denied. I was using a Twilio NBIOT SIM.

Hello ... @robbiet480 I'd be curious to hear more about this? I've got a SIM7000A here, newest firmware (AT+CGMR == Revision:1351B04SIM7000A) with a Twilio NB SIM, and was able to get a NB connection to work.

I use the AT Command Tester for SIMCOM, and got the correct settings from there:

@Humancell Weird. I specifically contacted Twilio support and they advised me the 7000G wouldn't work because T-Mobile didn't allow uncertified devices on the network. I moved to using Hologram.

Do you know who you talked to in support? (I work for Twilio ... ha ha)

Here is another test I just did:

@Humancell Nikolay Rusinov, support ticket # 4012120. He advised the only SimCom module authorized was the 7020G.

robbiet480 commented 4 years ago

If you can figure out what went wrong, that would be great because I'd rather be using Twilio!

Humancell commented 4 years ago

Hello ... yes, I believe that if you look at the "official" T-Mobile website, you'll see that there are only a few modules from SIMCOM that are truly "certified" ... but there is nothing related to the SIM that is stopping you from trying and seeing what works.

I know from working closely with SIMCOM they have the SIM7080G also in certification and I got two of them on line this week (with the latest firmware) for both Cat-M1 and NB.

If you have your Twilio NB SIM, give it another try with the commands above (Or using the AT Command Tester for SIMCOM) but make sure you have the latest firmware.

robbiet480 commented 4 years ago

I'll try to give this a try later today. I know i'm on the latest firmware for the G, maybe that's the difference.

alliedAB3D commented 3 years ago

Hey, Robbie. I'm tardy to this party, but did you ever get your SIM7000 working with the Twilio SIM card?

robbiet480 commented 3 years ago

Sorry, never got back to this.
