Will Apple Watch S4 work on ATT 4G

After setting up service with ATT, some spots I frequent don't get LTE. Service on my iPhone drops down to 4G instead of LTE. Will the S4 work in those areas without LTE? I can only find limited info about ATT frequencies but don't really know how to decipher this all and would like to hear from anyone that has actually used their watch on cellular other than LTE.

What I found for ATT

Apple.com tech spec page shows this

I believe it is LTE only. Now you may find some areas that your phone drops to 4G that the watch still gets LTE since there is nothing to drop down to and it’ll still try to connect to LTE and work. You have 14 days to test it out to see how it works where you live.

Apple says the AW is LTE and UMTS "capable" as listed on their tech spec page for US models. The ATT network frequency information I can find seems to indicate they still use LTE and UMTS. I just wonder if anyone has experience actually using it outside of LTE coverage since on paper it looks like it will work. I'm outside of my return period now and I have a plan with a sim that doesn't support an added device at the moment, so before jumping through hoops to get a new sim, and paying activation fees and service on the watch, I wanted to hear from others on it.

The UMTS frequencies Apple states on their website are-
  • UMTS
  • 850 MHz
  • 1700 MHz
  • 1900 MHz
The ATT frequencies I found are-

Frequencies used on the AT&T Network Frequency range Band number Protocol Class Status Notes

850 MHz GSM/GPRS/EDGE 2G Decommissioning by 2017[30] Plans to sunset 2G network by approximately January 1, 2017[31]

Does AT&T still offer the free 3 months like all the carriers did last year with the launch of the Series 3?

No, they have 1 month free, activation fee is $30 I think. But I would need to switch my plan and sim to even try it at this point.
