I cannot get my Pebble Tracker to connect when using either the AT&T LTE-M or NB-IOT SIM card. I am located in NC and my wife subscribes to the AT&T cell phone plan.
The device is fully charged. The SIM cards were activated. First, I tried the LTE-M and had no success. I purchased the NB-IoT card and got the same result. No connection. I canceled the LTE-M plan with AT&T and now have just the NB-IoT plan.
The device appears to be working correctly. There are 8 dots streaming across the display in the upper left-hand corner. I understand this is the signal trying to connect to the AT&T network. There is a SIM card icon and battery level displayed. There is a blue light flashing about every 5 seconds. The IOTEX logo flashes when you first turn on the device. The text displayed reads, "Riverrock v1.0.8 NB-IOT Main-Net.
I have tried reinserting the SIM card. I even took it to the AT&T store and had a representative insert it. I have turned it off and on many times. I have pushed the reset button several times. Nothing seems to work.
I contacted AT&T IoT support and they said “Please check your APN should be “m2mNB16.com.attz”, and restart your device.” I don’t know how to check for my APN.
I don’t know if it’s the device, the SIM card, or the network. I have asked for help on the different social platforms but no one seems to be able to help.
Can anyone help me?
