Heading to Dolliver Park? Well once you enter the park there's thick trees around, everywhere so there is no cell reception at all at least on my LG ux 830 and Motorola razar v3c. If you got your signal alart turn on, turn it off, it will bug you lol.

Well I come accross this road a lot and I notice once you start going down hill just west of startford on Iowa 175 you lose signal, my phone said "No Service" so its a dip with trees around blocking the signal.

My 3G service is horrible. Droped calls, full service then I make a call it dropes to 0. I am about to switch to Verizon for the new Android phone.

no reception in this area

No signal in the whole town.

this entire area is either completely dead or one bar and absolutely no 3G. most of johnston and grimes is only 1-bar of edge or dead. AT&T, please get with it or i'm switching. my whole family has Verizon and they have full reception out here.

Only time we get reception if we drive out of town.

absolutely no reception. need a cell tower in the valley area there

In Spirit Lake, IA get one bars or zero with iwireless{affiliate} Only 13 miles about south. In Spencer,IA get full bars with iwireless. Every time pay bill have call T-Mobile and have them put me back on roaming{longlines} tower. Have full bars in either town with roaming. T-Mobile great in MN. Took me day and half get roaming tower. Hope iwireless or T-Mobile put more towers up. Still not able make calls with full roaming. Call in every month for least an hour. All they say is am sorry. T-Mobile has horrible customer service. IA sucks with T-Mobile but more expensive if I change carriers. Dont have T-Mobile in northwest IA!

"More bars in more places" - not so much. No signal in "best" coverage area. I realize the coverage map is just an estimation, but it couldn't more incorrect. It's like me saying the sky is orange, and then following that with a disclaimer that my observation of the sky was just an estimation.
