MR1100 suddenly cannot connect to cell service

[navibean9]

"Help!"   I have an (out.of.warranty) MR1100.   It worked fine for about a year - and then suddenly stopped yesterday. 

The error message on boot-up says:  "Mobile Broadband Disconnected - Your data connection is disconnected."

I have AT&T cell service.     Here's what I've tried - all with no luck so far:

* New SIM card:    My carrier Consumer Cellular (reseller of AT&T service)  suggested a new SIM card.  I replaced the SIM;  They updated their records to point to the new SIM card.   No luck.

* Reset & re-booted:   I did a reset w- the button inside the device.   And I launched the AttWifiManager page, and I reset to factory settings. 

I re-booted after each change. 

* Possibly noteworthy-   I am testing this at my home:  I'm in a US suburban metro area with decent AT&T coverage.  But it's (only) decent enough for good voice service, most of the time.  So I typically only see 3 bars of signal strength. 

* After all these fix attempts, the error message is the same:  (That line above.)

THANK YOU in advance for any suggestions you can offer!

Hi Florence -   Thank you for reaching out. 
   No, I am still searching for an answer.     I will update here, if I find something useful.  
   So my connection to cell service suddenly stopped last week.  When did your connection drop out ?
Thank you.
