I posted previous about unexpected charges ($26) against my SIM and I see my previous post has been deleted from the forum. Another user (@dncworks) chimed in on that post and said he also had unexpected charges on his SIM. There has been no response from sixfab. I expect this post will also be deleted.
To add insult to injury, the charges occurred when the modem (LE910C4) wasn’t functional. I could not ping the internet and I would see “Cellular Connection Unavailable” on the SIM console. Later, @ensar fix my modem magically and now I can ping the internet, but I have a $26 charge against my SIM I would like removed. (I say magically because @ensar provided no explanation on how the model was fixed. I gave remote support access and it was fixed. I’d really like to know what was fixed in case I encounter a dead modem again, but no root-cause or fix was provided).
