Is anyone having problems with this phone?


Jan 27, 2005, 12:55 PM
I have heard that many people are having problems with this phone. What kinds of problems are happening with these phones? I've been warned not to buy this phone. Is this true, should I not buy this phone?

I wasn't until last night... that's when I discovered the phone will not receive a call in analog mode. It'll place calls in analog just fine, but will not receive them. I have duplicated this behavior on 100% of the roughly half-dozen 7400's I've tried.

I e-mailed Sanyo about the problem a little while ago. Hopefully they have a software update on the way for it. We'll see.

As for other issues... some people have complained about calls fading out or something like that. I have not experienced that, but don't doubt the problem exists. There are some problems with the Tegic T9 predictive input system within MIDP applications (downloads). Other than that, it's a rock-solid phone... one of my favorites.

Well to my knowledge analog has never worked (at least with other phones I have had) for receiving calls (the phone actually ringing). Further, don't expect your voicemail to work either, because that information is sent digitally. However, you can still check your voicemail in analog.

In my area, voice mail notifications work fine in analog mode (roaming on Alltel). Always have.

I see your on Alltel, how does this phone work on the Alltel network? Anyone using this phone outside of the Sprint network please let me know how well this functions, especially Alltel. I have this phone but my main problem is I can get it programmed to work with Alltel network since the reps at Alltel are uncertain of the programming menu also they need a SPC code which I understand Sprint usually suplies. Anybody that knows how to program this for Alltel, please contact me.

I'm not on Alltel. The phone is ROAMING on Alltel. Without the SPC code (which Sprint will only supply for purposes of activating the phone on their network), it cannot even begin to THINK about getting activated on Alltel's network.

I drop 60% of the calls I am on. I am on Sprint network, and they have been extremely NON-helpful on the subject. I have had their technicians out to check on the signal level and they called me and told me that I lived in a min. to no coverage area (same for my work location) and that they were not planning on improving the signal strength at this time.
I live in the mid-west portion of Phoenix and work in the north portion where I would consider there should be full strength signal. Its almost in the center area of Phoenix. Doesn't make much sense does it. Stay away from Sprint and their cust service, if you don't drop the call it takes them 20-30 min to get to you. Use speaker-phone and read a book!

how can u get a voicemail notifications on the phone in anolog ??? thats impossible..you cant send a digital item over anolog network.

Analog networks have had support for voice mail notifications for years. My first cell phone was a Motorola MicroTac 650e (360 Communications, 199Cool. All analog. Voice mail notifications worked just fine as long as I was on 360's network.

Analog networks also support transmission of caller ID, and even text messages-- though SMS is inbound-only and limited to 12 (maybe 16) characters. Not all analog systems support inbound (MT) SMS, but I know the old 360 Communications (formerly Cellular One, now Alltel) system here does.

One time I was fiddling with the ringers and the phone totally froze. It wouldn't do anything, not even power off. I had to pop out the battery to restart it. Other than that, so far so good.

Mine has gone totally dead and I'm being told that it may be a problem with the circuits of the phone. It won't recharge any at all. I need parts but here's the catch, I live in JAMAICA! And I love this phone and refuse to have it die. By the way, know how I can unlock it?

I just took mine back to the store and got another one. My phone was dropping every call even with full signal strength. I got another one and I still have dropped call problems. I understand that it could just be a bad batch of phones since I took it back and exchanged at the same store. Love the phone though. Gonna keep tryin till I get one that works right. Confused

Are you inside of a building, office, home, or store when this occurs?

If you are dropping calls and have full signal, this is likely due to a sensitivity issue in the CDMA radio. depending on how close together in series with the last phone that you had, it could be a bad batch of phones. this is because, when semiconductors are purchased, it is usually in bulk, and they are made in batches, alot of time you can get thousands of them from one sheet of silicon. If there is a defect in one, there is likely a defect in the rest. Or you could just be having bad luck. I love the performance of my 7400, all except for the crappy hinge that cracked within two months. But I will be keeping this phone indefinitely, which is odd, because i usually change phones monthly, i like to keep it fresh.

I took mine back and got a 3rd one and its been great ever since. Love the phone. I am just like you in how often I change phones but this one is a keeper(till somethin else catches my eye.)

I am on my third MM-7400. The first one would not make outgoing calls (even though the Airgate store said they were having network problems and made me deal with it for over a week). The second one's external screen died after 2 months. This one is getting flaky after 5 months and I am going to make Sprint send me either a Sanyo 7500 or a Samsung Blade once they both come out and I make a decision on one of the two. This phone's major strength is its superior signal strength. I have dropped exactly two calls in two months in the Charlotte, NC area. This includes driving and talking all over town, and I have used about 4500 total wireless minutes per month since I moved here. The phone has quite a few drawbacks though. The sound quali...
