Of course you can (and probably should) be "sneaky" about it and have alter motive to go to that city, say you go to a concert or maybe it has better movie theater or maybe there is some kind of conference. About using the phone in places you don't routinely go, I can think of at least couple places like coffee shops that are within range of another public wifi which I don't normally associate with.
