Using a factory unlocked iPhone 4S running on T-Mobile. Usually 4-5 bars and no problems with voice calls from the Waipahu to Ala Moana area. Data is of course limited to EDGE which is ok for me since I only use email and limited web browsing.

I have excellent reception everywhere I go on Verizon Wireless. I also have great 3G internet coverage most of the time, pretty much anywhere on the island. I'm only writing this review because I switched to Mobi. Mobi sucks big time! I can't believe how often this company has internet outages. In this day and age, cell phone users use their phone MOSTLY for internet. Yes, I make calls and do text messaging, too. Text messaging is a FAIL too, sometimes. Even the guy who sold me the service told me MMS (multi-media messaging) wouldn't work on Mobi. He didn't tell me that even SMS (regular messaging) wouldn't work occasionally! These incidents happened in Kahala, Kaimuki and Hawaii Kai. In town, I haven't had any trouble. If this is my experience on a phone, imagine how bad their Hele broadband device is. I don't have to imagine. I met a solar panel salesman today who said it was the most worthless brick he has purchased and couldn't wait to switch to something better. I wish Verizon wasn't so expensive. But I will be going back. I've tried T-Mobile and that was even more frustrating then Mobi. There pretty much isn't anything else in Hawaii as consistently solid as Verizon. They are the gold standard.

I always get great 3g whenever we travel around the area. I've had T-Mobile and it was ok and Verizon was ok to good but I have had excellent service with AT&T here

Hey Jim Clement, it might be your phone. I have an iPhone and my bars are always full with Tmobile. It is TRUE about T-Mobile and it's towers. T-Mobile used to have agreements with AT&T to use their towers in many areas. Well that agreement vanished a while ago which is why where you used to get awesome reception with T-Mobile, now it sucks. I am considering switching to AT&T, but then again I've been with T-Mobile since voicestream and I'm just hoping they do something about adding more towers. It's getting ridiculous. One thing about AT&T in Hawaii (ALL ISLANDS) is that they always get dropped calls, super annoying. It shows full bars, but it is often misleading because often my AT&T friends can't even make an outgoing call! You also have to consider the fact that with more AT&T users, their towers can get jammed at times, which explains the dropped calls. T-Mobile will eventually get there if they don't keep up with adding more pipes for the water to flow, for a better word. AT&T's 3G is light years faster than T-Mobiles without a doubt. T-Mobiles 3G is a joke. Seriously. One thing I do know for sure is that I'm leaving T-Mobile if they don't step their game up fast. My reception is good, but I'm sure it's due to the fact that a tower is just 3 blocks from my house and I'm in a high rise... I want only the fastest, most reliable GSM network. I don't like CDMA's... sorry Verizon and Sprint... .sucks...

Love my iPhone! Love AT&T! Always have excellent service!

always have 5 bard switched from Verizon who has no bars anywhere. I love it!

I've never dropped a call in the past two years I've lived on this island. I get reception all over base with no issues.

5 Bars are the norm near the top of Kamehame Ridge. 3G reception is excellent.

Excellent reception in the Davies Pacific Building and surrounding. I've never had a dropped call at work while on Nextel's network.

AT&T work greate both voice and Media NET connection. Voice is clear enough and data runs through fast enogh with 3.5 G most of the time.

I drive all over this island and shop at Ala Moana, Ward Center, where ever. I can talk on my phone all the way at the bottom floor of Ala Moana with no problems. I have noticed a few spotty locations heading up towards the North Shore, but they are few and far between. I can talk in my house without problems. No static, no dropped calls. Verizon works better here than it has in other places we've lived (Fort Ord, anyone?)

The reception of Verizon for me has been excellent in Hawaii. I haven't tried out of state but I always have connection, even in most elevators and places where tm, cingular, and many others don't, I even got service at the rest stop at Mauna Kea!

I have not had any problems for the last two years.

I love T-Mobile. Their customer service is great. I can get service almost anywhere on the island! My phone doesn't work in elevators, but that's just fine.

I have had Verizon Wireless for 5 years. They are FANTASTIC. Great, customer service, and GREAT coverage too. I take that back. Not just GREAT coverage but AWESOME coverage. No exaggeration... I am able to get coverage in various parking garages around downtown Honolulu - Melim Tower, Harbor Court - in their elevators too! - and I even get coverage in their fire exits too. Overall, I've been very happy with Verizon (equpiment, coverage, etc.) for the entire 5 years I've been with them.

Excellent reception here in the Hawaii Kai area.

Phone Display shows 5 bars. Float's Mobile Agent 0.1.0.30 XE averages 80-90% signal (connected via Bluetooth serial connection).

well we know that salt lake doesnt have the BEST of receptions but when i go to town i get really good reception.. better than attws gsm and sprint and verizon

Coverage is pretty good but there are some spots where you will have drop calls in the following areas: Pali Hwy. - near reservior, just outside the tunnels town side, near the hairpin turn and near HPU; Likelike Hwy. just outside the tunnel town side and near overpass before Kalihi Valley.

Almost perfect on base. In some areas of the PACAF building you will lose your signal but I haven't found a carrier that can deliver in all areas of this huge multi-walled building. Many time you will get a message alert even if you don't get the call in the building which doesn't happen with some other carriers. This way at least you know you have missed something. Otherwise Oahu coverage is great as is coverage while traveling on the Mainland.
