If you're in a weaker signal area, the Pantech will be faster since it has a stronger antenna, particularly on the upload. Plus, you can connect an external antenna to the Pantech, if needed, to boost speeds. However, in a strong signal area, your phone should be comparable in speeds. At least this is what I've experienced with the UML290 vs. Thunderbolt.
Ok im a truck driver say the pantech has 2 bars of 3g and the phone has the same will the speeds be the same download side i hardly ever upload anyways
I've never tried the Pantech in a mobile environment, but at my house, the DL speeds are about the same for the Pantech and Thunderbolt when both have the same signal. I'm in a weaker signal area.
