Does the iPhone 4 hate the AT&T MicroCell?

Same issue, Microcell isn't consistent. One minute you see it on your IPhone connected and the next it's gone. Of course, I'm using the IPhone 4 but I seem to remember having the same issue with the 3gs. Luckily, I am one of the one's who go it for free. It's a great concept if they (ATT) can actually get it to function properly. It's very disappointing.

AT&T says it's the phone, Apple says it's the coverage. I've been with AT&T since Cellular One and they still won't do anything for me. This is absurd and I'm going to return the phone. They wouldn't even meet me half way or subsidize a booster.

I have an iPhone 3GS, iOS 4.1 (just upgraded yesterday; previously 4.0), and the Microcell. I have the problem with garbled calls oftenbut irregularly. One other problem I've noticed is sometimes when placing calls the call fails immediately. Placing a call after that usually results in a successful connection.

I just spoke with an AT&T help desk person and they said there is a known problem specific to iPhone and the Microcell. Call this number:

888-334-3787, when prompted, type in this PIN: 88346

AT&T says they are currently awaiting a fix that is being developed between AT&T and Cisco (the manufacturer of the Microcell). They said it is NOT an issue Apple can resolve. In the meantime, they recommend that you turn OFF cellular data (Settings > General > Network > Cellular Data ) AND turn off WiFi (Settings > WiFi ) AND turn off Location Services (Settings > General > Location Services ) during the time you want to make phone calls. They apologized, but that's the extent of the solution at this time.

So, basically, your 21st century iPhone is as useful as a cell phone from 1989 until the fix comes in.

Whats really pissing me off is that I too have an iPhone 4 and a Microcell and worse phone calls then when I had 1 bar in my house. I am reading EVERYWHERE that everyone is having this same issue with iphone 4. I called At&t and have spent the last 2 weeks with them on the phone as they ask me 1,000 questions and try to get me to go replace my unit. The worst part is they are all acting like this is the 1st time they've every heard of this problem. Clearly this is a MAJOR issue and AT&T has to know a very good amount about it but they are constantly treating me like i'm an idiot and don't know how to use my microcell properly. "Sir, lets try to set it up again and see if maybe you set it up incorrectly" Like you could even do that! "Sir, you must have a bad unit because our engineers cant figure out what could possibly be causing this.. so why don't you go and have it replaced at a retail store". Obviously if everyone has this problem getting a new microcell is not going to fix it! AT&T is just really making me mad about this.. make me pay $150 to fix my service I already pay for and then they make it worse and stick me with this pice of junk because they spent 2 weeks trouble shooting it which put me over the 30 day return period!!
Way to treat me like I'm the best part of the AT&T family as you always say when I hang up!

My husband bought the microcell this summer while I was out-of-town. He has the iPhone 3Gs. The microcell works okay for him -- better than having having to stand in the corner of the kitchen and not moving, but not what one would hope for as it does drop calls. I have the iPhone 4 and can hear only the first 3 or 4 words of a conversation when the sound transforms into constant stuttering. I appreciate everyone's suggestions and plan to try them all. I'll let you know what helps. While I'm incredible frustrated, I'm happy to know that I'm not alone in this.

I do have the stuttering issue. It's not all the time but it is very irritating when it happens. Too bad too because it's usually pretty solid.

FWIW I am on an iPhone 4, Comcast HSI, through an Airport Extreme router.

I'm an iPhone 4 user and I've had the stuttering audio problem at least half a dozen times in the three weeks I've owned my Microcell. It usually dissipates if I shift slightly or move closer to the M-cell.

Today I was on a conference call and I lost audio mid-call (ARRGH). Oddly, I didn't get the typical 'Call Failed' - audio just cut out and so I hung up. When I hung up, the iPhone proceeded to lockup. I then looked up to see that the m-cell was wireless signal light was flashing. I think it may have been receiving a software update. (According to the manual, if the wireless signal starts flashing that is one possible cause.) Power cycling and a 5 minute wait later, and the m-cell was back in business.

I've probably had about 5-6 dropped calls in the 3 weeks I've used mine. I've noticed that it can happen even with 5 bars of m-cell reception. But this is vastly better than before (I would average 2-3 dropped calls per day on crummy 0-2 bar coverage in my apartment).

Thankfully, I still have about 5 days to make up my mind on whether to keep it or not.

Same issue. I just bought 3g Microcell. Hooked it up. Full bars. My setup is a Comcast modem (11mb download/4mb upload speeds). Apple Airport Extreme (duel) router, Apple Airport Express extender, Microcell and Router hooked up through Pluglinks so the 3g Microcell can be centrally installed in house.

My wife and I have iPhone 4's. Garbled choppy sound when hearing people talking. They can't tell any difference on the other end though. It happens for seconds or minutes. Best when closer to the 3g Microcell. AT&T rep pointed me to this blog. They said turn off the data. It's a problem with the phone. Not the AT&T equipment or signal. Apple needs to fix it but they need to work with AT&T.

If you want to return your microcell after the 30 days, AT&T will give you a $100 courtesy credit. You can then sell your microcell on ebay for $125 including shipping.

I am waiting for the firmware fix.

I have the same stuttering audio, I cannot understand the person I'm speaking with.

I'm on my iPhone4, connected through the Microcell.

turning off cellular data fixed it.... but I only consider this a "workaround"
it cannot be how customers are expected to actually use their handsets
because the network is not built out enough and I'm trying to use this microcell solution
to fill in.

I know that Apple just did an update that closed the PDF exploit that
allowed the jailbreak.... maybe they can do something that would really
be wonderful and get my cool new iPhone to play nice with this microcell.

Please.... :)

I even paid full price for that stupid microcell.
and I'm on contract for like 23 more months....
either get them to build out there network around my neighborhood
or "fix it" so the microcell will work as it should with an iPhone4.
