A little over a year ago we switched to Sprint because the savings was huge. We researched and according to all we saw, the signal at WP should have been good (this was before DS was accepted). Unfortunately, that was not his experience; he frequently had a weak or insufficient signal. We switched back to Verizon's "we want you back" deal, and DS has a great signal. We were there this weekend for PPW and very rarely couldn't get a signal--if you are deep within the granite walls, it doesn't matter who your carrier is, you're not getting through. For day-to-day business though, Verizon is great for our son.
