Phone is useless indoor or out here. Need to hop in car and drive a few blocks to get any reception. And this is close to the I-5.

Horrible service here, both inside building and outside. Have to walk around the building to go from 0 bars to 1 bar. Phone will eventually start to "domestic roam" but still very poor service especially on the data side of things. This is irvine, not the back woods of montana. What's up, Sprint?

Always have 4g great network never drop calls

Sometimes spotty 4G coverage. There one minute and without moving, gone the next, mostly on clear mornings. What's up with Verizon??? I know I'm not an expert on air waves, but sitting at my desk without moving and going from 4X to 3X to 1X and sometimes nothing throughout the day just seems odd and sucks when using unlimited data to listen to Pandora... (company won't let me connect through their network) :( But the majority of the time, I get a strong 4X connection so it's overall a good service.

AT&T wouldn't give us femtocell, although they said they would in letter. I was 2 days late. Zero service in the house or near any bldgs, and lousy customer service. We have 3 phones on family plan and am dying to switch to almost any decent non-AT&T provider. It seems like Sprint looks good in irvine?

Even using wifi calling with uma, no service 80% of the time. I checked with the T-Mobile store, since T-Mobile's own website say's full coverage (as of 7 / 22 / 2011) and they say sorry no coverage. and nothing they can do... .. I asked for a cell booster, they said its in test in Inland Empire and San Diego only. Too Bad, but I get what I pay for... .

Very poor reception at the San Leon Villa Apartments. I usually have to stand outside in my balcony and even then I get a lot of dropped calls. Verizon step your game up, and really "rule the air."

I have perfect reception everywhere I go in Irvine! Love Sprint's plans. Way cheaper than Verizon and at&t. Oh I also get 4G in parts of Irvine very very fast I get from 6mps to 8mps down. Sprint's EVDO Network is also very fast aswell, usually from.79 mps to 1.04 mps. I definatly would go with Sprint if you want what I am getting(amazing service / amazing phone)! BTW Sprint has unlimited data and they dont slow you down! hint:tmobile

Trying Verizon with ipad2. Bought 3 for family after 6 hrs in line. Hope I did not make serious error.

February 20, 2011. It seems the quality has deteriorated the last few days. I wonder if it's the rainy / cloudy weather; but signal should not be that sensitive to weather. This is weird.

Does not work in all rooms where I live. I had to get the Sprint Airave installed to use my phone at my place. Sprint wanted to charge me $99 for the Airave plus $10 a month to use the Airave which would allow me to use my cellphone with 4G (no 4G in Irvine btw). I said no and that it would be cheaper to just cancel this contract and pay the etf instead. They sent the Airave for free and waived the monthly charges for using it. Again there is NO 4G in Irvine. The 3G is below average. I wish I had ZERO data plan because I use my wifi for my phone 90% of the time.

no reception in the morning in my house and up and down for the rest of the day. seems to be the most challenged indoors (everywhere!). I'm thinking about switching to Tracfone for better coverage (or so I'm told), but, read some bad reviews of them on the web. What is the best "pay as you go" phone / service between the tustin mktplce. and the beach (my calling region). If anybody knows, could you give me a shout out pleeeeeeaaaassse, I'm Dyin' Over here =)

I consistently have dropped calls in most indoor areas and even some outdoor areas. Very frustrating. I thought Verizon would have fixed this by now.

Finally after 10+ year I get decent coverage with AT&T. Seems to have happened just this week. Most of my family already switched to Verizon because we couldn't even use our cells for calls at home, but I stuck with AT&T. Let's hope this increase service is permanent.

Today, October 2nd, both my wife and I noticed that we suddenly have 3 to 4 bars. Before we had 0 to 1. AT&T must have activated a new tower? Anyone else noticed the increased signal?

I heard bad things about AT&T in Irvine, but I wanted an iphone 4, and people told me that AT&T coverage had improved over the past year. Well, it has been o.k. in my house (off of Yale Loop near Jeffrey and Alton) I get 1 bar inside and sometimes 2 bars on the patio. Some calls are fine, and sometimes I drop calls. My office is at the Spectrum and I get maximum bars inside my office building all the time. It's great. Also, driving around Irvine, Tustin, Costa Mesa, Newport, etc... I rarely have any problems. I've had Sprint and Verizon too. In 2007 I was with Verizon and couldn't get one bar in my house near Culver and Michelson. I think Sprint is the best overall, but they don't have iphone and that's what I really wanted. My advice: get a cheap landline if cell service in your house is bad. Land lines are really cheap now. You can get a plan for about $9 per month.

With Femtocell that I pay for to get a signal at all, it is dreadful. Can't wait for the end of the contract and the commencement of another carrier selling the iPhone.

Neither phones, iPhone or Blackberry had absolutely NO RECEPTION in my house... I have to stick my phone o my window sill in order to make calls. In the end I had to used my PSP's Skype to make calls within my house. Outside of my house the reception is still very spotty. Had AT&T on and off, but this time around its much worse than before. I know phones have a lot to do with it, so I guess this is a testament of how poorly the iphone does in this area... but my Blackberry Curve didn't fare much better either.

Since I moved to this home, my coverage is so terrible. my wife now uses land line to call me at work. My phone drops calls all the time, although it's slightly better in the backyard. Terrible, terrible, and a major disappointment.

very poor reception, no reception in my house, drops several time phone call when I get in the gate of northpark.
