Yes and no. If its an international 710 and not originally from T-Mobile it will lack T-Mobiles HSPA+ band so 4G is out the window. Otherwise it should be able to connect. I know the North American phones are pentaband, so if the international phone is the same then you will be able to connect at 3G speeds.
I would try and get a T-Mobile branded 710. Just got mine, its great
