I am shopping for a refurbished CDMA phone from Ting. I really want one with a good antenna as there are two huge hills between me and the signal tower nearest my house. Hindsight is 20/20, and I wish I had asked the phone models of friends & family that actually got signals out here. I do know that they all had CDMA phones. The iPhone 4 is definitely within my price range, and the Samsung Galaxy III & the iPhone 4s might be. The best antenna would be worth trying to find the extra money for. There are other phones I could afford, but I have no confidence that they could hold up to iPhone and Samsung in this regard. Does anyone have any experience that would help me with this? Thanks!
