Unlocked APN Settings for IOT product.


We are using your AT&T sim card and TELIT cell modems to develop our IOT products. 

Because we need to update TELIT Firmware, the TELIT cell modem is required to connect to our FTP server. 

We are located in Canada and we manage to connect to our FTP server using APN setting isp.cingular on GSM network.

We would like to know the APN setting on LTE network and cat-m1 network so that TELIT cell modems can connect to our FTP server.

Probably won't work.  If your devices are not connecting, it's more likely a problem with your plan or excluded devices than with APN settings. 

     What plan are you using? 

AT&T provides prepaid and postpaid roaming phone service in Canada and Mexico.  And tablet roaming on postpaid plans.

I don't think anything else roams free.  

The hotspot plans do not. 

The 3g shut down has At&t limiting devices to those whitelisted. 

Contact AT&T directly and see if they can sort out if your plan even allows the devices or service in your location.
