have a quectel EC25AFXGAR07A04M1G module with an AT&T sim card. Got it to work sending out SMS then moved it to a another computer and started to use it on that pc then it would not register on the att network. put it back on the original pc I had it working on and it will not register any more on that pc. SIM is fine in my phone. when I look at at+cgdcont=? it does not show the same response it has been showing for a month now. it was showing [2025-07-29 16:34:44:053_R:] +CGDCONT: 1,“IPV4V6”,“nxtgenphone”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0
