My area is in the Carolina's where I understand most all of the 3G service is on the 1900Mhz band. I have personal (Nexus 5) & business (Samsung Rugby Pro) accounts on AT&T and both SIM's are currently provisioned with LTE. I have been using my Nexus 5 SIM for testing. I can select my Nexus5 to 3G only and get HSPA coverage.
I have updated the phone per shwetkprabhat's guide :http://forum.xda-developers.com/show....php?t=2559891 and also installed KitKat 4.4.2.
The phone is selected to the GSM/WCDMA Auto mode. I have selected other modes from the Network dialog as well as selected other modes from withing the "Service" menu. All with no results but EDGE connection speeds.
I selected the default AT&T provider APN settings on SIM setup and they appear correct. I have also tried other settings I found on other sites including settings for International phones from AT&T's support site.
So. Are there any users here with a HTC One China Unicom 802w successfully using it on AT&T with HSPA data speeds that can tell me where my problem might be?
Or is it that this phone won't work with nothing but EDGE connectivity period on AT&T...
