Error 2172 Upon Send With Quectel modem. Tmobile Phone Card

Im using SMS Deliverer software. on Check all things look good and go. On Send the subject gets a 2172 error. I have tried SMS Caster Enterprise and got the same 2172 Error upon send.

The book says unspecified communication error I think. My drivers may not be up to date. If Im right can someone send me the latest firmware, drivers and windows 11 software update? Thanks.


hello, what’s your module type and current firmware version?
