Losing Data Signal

I generally have a 1XEV signal on my Tour. But at times, in the interior of some buildings, I lose signal. Then why I return to an area with signal, I'm stuck on 1x, and it won't reconnect to XEV, without a reset. I try and turn off signal and then back on (using Manage Connections) but it acts very sluggish, like it won't immediately disconnect, or then when I check it to restore connections, it won't check immediately. Hence I just give up and reset. Is there anyway to "fix" that or is a reset the only way?
