I have a samsung S4. Bluetooth isnt a problem but it seems to be for calls only it doesent seem to allow file sharing or tethering. This might be a hardware problem tho, I was reading a review that these things wont run torque without a USB bluetooth adapter. Im starting to see there may be a few things left to desire, alot of witch seems to be lost in translation.

Man I love chinese tech support. Their solution to everything is well send you a new one

Before changing providers read users' feedback about it on the internet. It can be very interesting and informative to learn about the experience of other users. You can also check the responses of the residents of your area. It is easy to do it by refining the search by zip code. I recheck my postal code on the page San Diego zip code. It is true, that sometimes the providers promise services that eventually do not work as we expect.
