I have an unlocked Rogers HTC EVO 3D and I'm using it on the Fido network. I have almost no problem connecting to the 3G/4G network. When I enable the mobile hotspot or try to tether my phone to my PC using USB the mobile data network disappears but the phone still says it is enabled. It will not reconnect to the mobile network until I manually disconnect and reconnect to it. I'm not sure if this is a phone specific issue. If this thread should be in the EVO 3D section could a mod please move it there. Thank you in advance for the help.
