Unfortunately, I don't think that CID=1 is always the one that the<br>
module expects to use as initial EPS bearer, that may depend on the<br>
modem. So, if we were to add a logic that assumes "initial LTE bearer<br>
settings are those in CID=1" then that would need to be tied to a<br>
specific device.<br>
<br>
Didn't Verizon require to use CID=4 for the same purpose in their<br>
modems? (or something like that) @matthew stanger what was that about?<br>
I recall a patch were we allowed specifying the CID to use explicitly<br>
via Simple.Connect() for this very same purpose.<br>
