Arch linux phosh - no cellular with T-Mobile sim

[Conjada]

Haven’t been able to spend much time on it. But, it kind of looks like I have a problem of some sort. With the nano sim installed using two different adapters, Settings says “No SIM. Insert a SIM card to use this modem”. Sim works fine in my fruit phone.

ETA: i don’t see any physical problem with the contacts for sim. Is it possible that i have somehow ignorantly crashed the modem firmware? Just guessing and looking for a plan of attack on the problem…

If you suspect the modem, you can try directly talking to the Quectel and see what's up. 

Or it could be the simplest of things like SIM not really seated / lined up.  I find the microSIM "sleeve", or whatever it's called that adapts the size, to be unforgiving.  I have to get it all lined up just right for a new SIM to really be seated in the socket.  Takes several attempts -- despite having small fingers!  (Unlike other folks, I'm not ashamed of small hands )

Thanks. I'll keep trying and will learn a little more about the modem. I've had the sim in and out many times and using two different adapters (the one that came with the phone and the one that came with the sim) and it has not picked it up, even once. I'll give talking to the modem a try. I'll be really happy when my keyboard gets here. Too easy to make mistakes typing on the screen... lol. Thanks, again.
