I need to use my Virgin Mobile HTC EVO 4G phone as a hotspot on my 1 hour bus commute, which takes me through areas without 4g (which is at least 1/2 of the commute, in and out of 4g coverage several times). I just received it and am trying to set it up as a hotspot at home as a test with only 3g coverage (no 4g coverage at the house). Most of the setup goes smoothly until I actually activate it, upon which time error 67 pops up (Data Call Failure) even though I've been using it to access the web via 3g with decent EVDO A signal strength (-75 db) My laptop can see the SSID and can connect, though once the error 67 pops up, the wifi connection is dropped. I can't even successfully connect the laptop through the phone when the phone is using my home wifi. Is there any way I can configure this phone to operate as a hotspot using 3g only?
