Has anyone had any luck using 3rd party SIM cards with LTE Boron? I’ve run through the tutorial but it seems a few months out of date. Not sure if there’s anything else that must be done. :frowning: I did throw the SIM in my phone and it appears to connect just fine. Also, the internal SIM connects…

Alright, 6 hours later. The conclusion is the following: The firmware, by default, does not set the APN credentials. The best way to do it without making changes to the baseline firmware itself is to run the following after a Cellular.on() (make sure Cellular is off before this) Cellular.on();…

I have had success with Hologram SIM cards, but not with Soracom or Things Mobile. The latter two never seem to connect. I’ve tried Soracom on a couple of Pycom devices as well with no luck.

Thanks @picsil I’m glad I’m not the only one here!

@rickkas7 Thanks. I’ve read that post, and do set AT+UMNOPROF=2 to try attaching to AT&T, and AT+UMNOPROF=3 for Verizon. On Hologram it works as expected. I can switch between AT&T and Verizon with those settings, or be connected automatically to one or the other with AT+UMNOPROF=0. With Things Mobi…

So for SORACOM, it requires a username and password to go along with the APN. The only place in the HAL driver that I saw referencing the password and username was in SaraNcpClient::configureApn. Unless I’m missing something, this is why it’s not working. The username and password is not getting se…

You can pass Cellular.setCredentials the APN, username, and password. The definition is Cellular.setCredentials(const char *apn, const char *username, const char *password). Cellular.setCredentials(“ soracom.io ”,“sora”,“sora”); That should work, but it doesn’t for me.

I did some preliminary testing with ThingsMobile (I’ll try Soracom next) and have it connected to AT&T successfully in the US. I’m using a modified boron-clouddebug that adds the following commands before Cellular.connect(): AT+UMNOPROF=0 AT+COPS=2 AT+CFUN=15 It takes about 2 minutes to connect, …

I think they only support AT&T. Verizon, in my experience, has been difficult to work with on CAT M1 deployments…

To give more context for my response: there are companies out there that have CAT M1 service for Verizon. PWS: https://www.pws.bz Nimbelink: http://go.nimbelink.com Their interfaces are not nearly as nice as these other guys but you do get Verizon service. (Their pricing is also not nearly as com…

It's possible that you need to manually select AT&T as your provider. Try following the instructions here, but set mnoProf to 2 to manually select AT&T instead of Verizon.
