Cingular Treo 750 Dropped Calls

Has anyone else had issues with frequently dropped calls?
I have had this issue with 3 Cingular branded Treos so far.
It seems to get progressively worse over time where I will be forced to get a replacement device.
I have had the same problem with 3 different ROMs (default WM5, leaked AT&T WM6, and Vodaphone WM6).
I have had my SIM replaced multiple times as a possible fix. which doesn't work.
I have made sure that my SIM and IMEI number are correct in AT&T's system.
I don't understand why I am having this problem and no one else seems to be complaining about the same thing. Does anyone have any advice for things I can check?

I take it from the lack of response that I am one of the only people who is having this problem. I guess I am just having bad luck with the devices I am getting. I think I will give it a shot one more time with another new device. I am jumping off the Treo bandwagon if it happens again to a 4th Treo.

Occam's Razor would point to the service. It's possible you're just making calls in an area with poor reception.

I wonder if those dropped calls are happening from a 2G to 3G handoff or the opposite. Do you have 3G coverage in your area?

Rom that fixes Edge/3g mistake?

I did search and I was sure there'd be a thread on this, but I frankly couldn't figure out what to seach for and got no hits. My Tilt makes the mistake of showing an "E" for Edge instead of 3G sometimes. My data rates seem to indicate that this is not just an icon mistake but an actual problem with the radio (though I am still not sure about this). This is all the more strange because, where I live, the telcos skipped edge and deployed HSDPA directly so I have no idea where this phone is getting an edge signal from. I have my Tilt next to a N95 and the N95 is showing 3g and getting faster transfer rates.
So my question is, which of the roms (if any) will fix this? Thanks!

I've had similar problems on my Tilt with every rom I've tried so far. The download speeds vary wildly, and the icon constantly changes between E, 3G, and H. Sometimes it changes every couple of seconds, even when standing still, in a typically good connection area. My GPS connection has similar problems. It's constantly jumping between various satellites, and never seems to hang on to the same one for more than a second.
I really hope a radio upgrade fixes these problems!

Thanks for the reply! That is too bad . Guess I will be sitting tight for an update .

Did you guys call AT&T about this? If they don't know they won't bother trying to fix it...
My Tilt stays on 3G or E, which ever I choose, very solidly. It might be just your area is a little weak on signal, which is a fix done at the towers at your location. So, you'll need to let AT&T know.

I don't know if this is reLated. I do not have 3G in my area but only EDGE. However I find my TyTn II uploading and downloading data at only half the rates to what my HTC Touch can manage. While my TyTn gives me around 100kbs the Touch can manage 200+kbs. I have tested repeatedly by swapping SIMs between the two. Could this be a radio problem?? Can I bank my hopes on a future ROM upgrade??

same issue here. I had to reboot few times and hope for the best. I was in San Jose ( EMC / Yahoo Campus) and was getting EDGE but I rebotted the device few times and it finally picked up 3G.

Been using this rom for a few hours now: http://forum.xda-developers.com/showthread.php?t=341886, and is seems to have fixed my problem. You should give it a try.
BTW, I got a Tilt as a gift but I have never had AT&T service. I am still puzzled as to where the old ROM was finding an Edge signal, as my carrier confirmed they never implemented Edge, just straight from GPRS to HSDPA.

Whats the gprs and 3g reception like?

Hi.
I have a diamond and compared to my vario 2 the reception on gprs and 3g is very poor.
I only need to be about a mile from the mast and reception drops out while my vario 2 still has 2 bars and my friends nokia n95 has 3.
Could anyone try a comparison. I need to know if the radio is better than my diamond before spending a lot of money on the raphael.
Thanks in advance.
Sean.

I have had both devices in a lab environment and the radio performance (at least on the radio versions I tested) was as near identical as makes no difference - as would be expected due to the hardware being practically identical.
Comparing signal strength by number of bars (especially on devices from different vendors!) is an exercise in futility.

Biiiig 2nd. The iPhone 3G's got complained about a lot because "they only have 1 or 2 bars of service" yet the people would never complain of dropped calls or slow data connections. I think the 2.0.1 update did nothing more than lower the signal required to get a bar.

My reception levels seem ok (i.e. bars) but my data speeds feel slow.

I work in London and get HSPA, 3G and GPRS completely fine and of course the unit switches between them accordingly fine! This is on my HTC Touch Pro, but sadly I don't have the Diamond to compare with, but logically it should be the same since same hardware.
FWIW I updated the weather using HSPA whilst on the train this morning without problem, so I guess it's all down to coverage as always! Vodafone are pretty good in London.

Hrm I'm in London too but on T-Mobile. My Kaiser is fine but the Touch Pro is definitely having data issues.
For example, it doesnt always initiate a data session when you need one, like whne you want to refresh your RSS or sync email etc.

Sorry to hear that, hopefully a ROM update (more specifically the Radio) will help you out! As always, the first ROM versions can be a bit funny which later versions iron out!
Out of coincidence, when you first started your Touch Pro, did you automatically set the settings according to the Network when prompted or did you perform this manually? I did this automatically as set by Vodafone network and all seems well!

Auto configured as usual...

Also in London, on Vodafone, and I'm going to say that the Raphael is pretty much identical for signal strength as the Diamond. Not found any places where it won't work yet (rail tunnels excepted). 3G signal still isn't available inside my house. But it never was with any phone.
I never had any problem with the Kaiser, Hermes, Universal, Magician, or any other device. All the reflashing of Radio ROM's that goes on around here for an extrordinarily marginal (and subjective) improvment completely baffles me...!
@Syphon Filter - My wife is on T-Mobile with an original Touch. Can't get a signal in our house at all unless she hangs out of the window or stands in the garden, but that's T-Mobile in South-East London for you...

Oh that's bad news. I was hoping the different housing could give the Raphael some improvement on 3G reception.
The Diamonds 3G reception is definitely worse then the reception quality of my TyTN and if the Raphael is identical to the Diamond...

Like I said, it's all subjective. I've never ever struggled for 3G reception on my Diamond in any location where my Hermes (TyTN) worked. Even in low signal areas, the Diamond has never failed me.
Admittedly speaker volume was better on the Hermes, but that's a different matter...

Well it's not that subjective because it's simply counting bars.
Where Diamond shows 1 bar, TyTN shows 2 bars - same location, same time, same network.

But how do you know that 1 Diamond bar doesn't equal 2 Tytn bars?

hi
I understand about the bars but the problem is how far from the transmitter you can use the phone.
There are many places where I can make calls and use the interner on my tytn bus I can't on my diamond.
at work I can walk about and have a conversation with no problems on my tytn but with my diamond I can only use it by a window.
listening to internet radio while driving is no problem with the tytn but with the diamond I keep having to restart the stream at various places when I lose the signal completely.
This is why a comparison would be helpful
Thanks to everyone so far for the feedback on this

This is of course a valid argument, but I also experienced, that the Diamond did not switch to 3G without forcing it by setting because of this weak 1 bar reception quality while the TyTN automatically switched to 3G.
So it seems that also the software internally assumed that the reception is too weak for 3G.
I would assume that the reception indicator is quite comparable between different HTC devices as the same operating system and the same manufacturer is involved.

Don't think I can add anything more to this discussion, on the basis that all of my 3G HTC devices have performed almost identically even in weaker signal areas.
I must just be very lucky? Best of luck to the rest of you though.

For me connection is definitely very very similar between the touch pro and tytn II. However I do think that the point at which is switches of 3g, becauase it doesn't think there is a good enough connection, may well be too early. It definitely seems to switch between 3g and gprs more often than the tytn II. Hopefully this can be fixed quite easily with an update.

Mine's going back.
My Hermes and Kaiser never lose the network in my house. My Touch Pro is constantly on and off. All with T-Mobile SIMs.
Shame 'cos it looks like a great device.

I have two phones here. TYTN II and a Raphael. Both on T-Mobile UK
The trusty TYTN II has 3 bars and always shows a 'H' whilst the Raphael is drifting from 'G' to 'H' and 1 bar occasionally losing a signal altogether.
I really want to like this phone but I might have to keep using the old one till HTC sort this out

I have both the Diamond and the Raphael side by side on the same network (Vodafone) and the signal strength is exactly the same.

I-Mate 9502 owners old and new - survey please

My 9502 was sent off to the seller requesting a refund just over 2 weeks ago. Thay have finally decided that they can't replicate the problem and are sending it to I-Mate (again) to repair.
I can see me getting fobbed off here so I thought I'd try this survey. I know a lot of people on these forums reported returning their 9502 because of the bug where it won't search for signal when on standby or had general signal problems.
Please answer the poll question and maybe post where you live and which network operator you use.
Cheers.

No problems here !
No problems using my 9502 through TIM Brasil ! Where I live I have EDGE (and GPRS, of course) only for now (3G will reach my city soon), but I travel daily to a 3G/HSDPA covered area.
Cheers!
Carlos

No Problems here too
I am in Melbourne, Australia. Have had my 9502 for about 3 months and it has not missed a beat. I have noticed that when it can't find a GSM connection, it will switch to 3G. Which is ok by me. I have not loaded it up with too many apps, just some for my basic needs. Even when travelling I have no connection issues.
1. SPB Plus
2. SPB Shell
3. TomTom
4. Resco Keyboard
5. Fizz Traveller.

Cheers for this guys. Keep em coming!

In Sydney Australia (Telstra) and havn't had any signal problems (have had the 9502 for a few months). I was also in the US recently and global roamed onto AT&T and had no apparent issues there either.

It is kinda looking like this is a problem with the 9502 on UK frequencies. Or maybe its a problem which the Telstra ROM doesn't suffer from.
I flashed tot he 6.1 ROM and it still suffered with it. It really did render it useless as I travel a lot.
Either way, I wish they'd hurry up and fix it or replace my bloody device. It's been gone 3 weeks now (+ 2 weeks the first time).

Come on UK users! Surely some people on these forums must have a 9502.

I have a 9502 and it never suffered such problems - it was always perfectly reliable (well, as reliable as can be when you are on Tmobile UK!). I did not flash the 6.1 upgrade and am just about to sell it as I have moved to a Diamond (and am likely also to get my mits on a Touch Pro)!

Did you use 3G? And do you get good receiption where you live?
I think it s a problem that only affects people in low signal areas. In my home and in cities it is fine, but if I go somewhere with no signal or if signal drops for a few seconds it will not search again until awoken. I travel a whole lot meaning it spends a lot of time sat in my pocket with no signal.
I am on Vodafone and have noticed that they have appauling coverage which I think makes the problem much more noticable. I live in a 3G area and get full signal HSDPA in my house. This is true for almost the whole area I live in for about 5 miles in each direction, however there are absolutely loads of 'dead spots' where there is no signal whatsoever, or where signal comes and goes.
And where my girlfriend lives, signal will drop every 5 minutes or so. Not a problem with normal devices as they just search again and have signal again after 4 or 5 seconds. The 9502 does not do this unless I wake it up meaning most of the time I am uncontactable - especially at night when I am not awake to turn the thing on and off.

I did use 3G and HSDPA (I use Direct Push so it is on permanently). I have terrible signal where i live (halfway down a steep hill in London) but it would only very rarely lose the connection. I would often have only one bar but that has been the same for all my phones. When it lost the connection, it would always regain it when I returned to a better position in the house.

As an additonal note to my previous post, in my work there are many buildings, and there are lots of spots with dead signal. When I pass through one of those areas, the 9502's green led stops flashing, but, as soon as I enter a signal covered area, it starts flashing again, of course meaning it has detected the radio signal.
If I wake it up right afterwards, as soon as I do it I see the signal bar and my operator's name, i.e. it has regained signal whilst in standby mode without problems.
Cheers!

That's interesting. Now I'm wondering its something to do with Vodafone, or if it is specific to certain devices. I tried my 9502 set to auto and european but it still suffered, although I know this fixed the problem for people in other localities.
Here's something interesting that may or may not be related: I go to law school on Manchester Oxford Road, right near Oxford Road train station. My SE P990i has always been fine there and gets full 3G receiption on Vodafone. The 9502 also displayed full 3G signal, however it was completely unable to recieve calls and text messages or use the internet. If I walked 5 minutes towards Picadilly, or once I got to Deansgate (the next stop) on the train home it'd work again and text messages would start flooding in. I did this every week for the 3 months I had it and never once managed to use any radio functions on Oxford Road! Bizarre.

[Q] Is the Fuze weaker in signal grabbing than the Tilt?

I changed from a Tilt to a Fuze. I now tried the Fuze on my wife's T-mobile. I noticed that the Fuze seems weaker. My working place is really bad for T-Mobile. With my tilt I get 2 bars and sometimes 1. With the Fuze, I get 1 and sometimes when I try and update the weather, I loose all connection. And sometimes I get dropped calls.
Now, I know the radio has much to do with this. But in general, has anybody noticed if the Fuze seems weaker than their old phone? I can't judge 3G/H because I never had it till now.

no absolutely not id say at worst the same if not better. It has all to do with the radio as well.

I figured as much. Maybe ATT optimized it for 3G network of theirs. I was hoping if anybody else on another network noticed a drop of signal quality with the stock rom/radio with tmobile.

I'm using the stock Fuze ROM, and I have worse reception on the bay area AT&T network. It's not a matter of bars on the display - it's that the calls are dropping in areas that never did with the Tilt.
My Tilt gets better reception. But it has a more mature radio. Hopefully this is an issue of radio firmware, and not bad hardware.

You do know where the antenna is in your device???
(read the manual)
In bad reception area's your hand can easily block the "low" signal....

I just switched from the Tilt to a Fuze 3 days ago and have definitely noticed the Fuze is weaker where I'm at (Statesville, NC).
And Karloe is right, the antenna is in the base of the phone, where I normally hold it. I've been holding it at the top and people on the other end of the line say it is clearer than when I first got the Fuze. Calls aren't dropping as much either.
Kind of awkward to hold the phone this way though....
It worked great when I was in Winston-Salem yesterday, had excellent 3G also.

I don't think the signal is worse than the Tilt. The display shows less bars than the Tilt did, but every phone displays signals differently.
As someone else said, the antenna is at the bottom, so you have to hold it differently than the Tilt.
So far I haven't had any dropped calls on the Fuze and I've had a few on the Tilt. Call clarity seems to be better on the Fuze than it was on the Tilt too.

Single is DEF worse then my 8525 I could take screen shots to prove it.

So far in my experience fuze has been giving me better reception that the tilt.

My Fuse def has less signal than my previous phones.
At my home in long island, NY I always had 4 to 5 bars on any phone I had.
The fuse only gives me 2 bars.

I live in a rural area and have noticed that while I usually only averaged two bars on my tilt, sometimes in a sweet spot I would get three.
The fuze peaks at two in sweet spots and a lot of the time it is hunting for a signal.
That being said, the tilt was the same way before I upgraded the radio rom many moons ago.
One thing I can say is that while the indicator shows poorer reception (it is just an icon) on the fuze, my call quality is better and is far less garbled during calls.

I work in NYC and with my tilt I would always have problems getting a signal in Manhattan. I could have full 3g reception in one signal spot, take one step foward and it would start searching for a signal. With my fuze Ive never seen less than 3 bars so far. It gets better reception than my tilt for sure.

My tilt had better reception while at home. The tilt never cycled through e -> g -> 3g like the fuze did. I agree that once the radio matures it will get better, but my stock tilt never had this problem when new. I also maintained a pretty steady 3g speed on the tilt whereas the fuze had huge swings in speed.
=

You have to security unlock your phone, but I just flashed the Blackstone radio and it appears to get a little better signal than my stock ATT radio did.
I know it all depends on the area and conditions, but some of you that say it has worse reception might want to try some of the different radios that are out there.

Same Bad Reception

I definitely agree. I would routinely get 4 bars with my tilt in my apartment. I'm lucky to get 1 bar with the Fuze. Anyone have a suggestion for the best radio for those of us who have not security unlocked yet? I'm willing to do the unlock if there are no other viable options.

Thank god I'm not the only one. My TILT always had full bars on 3g at home in my condo in Chicago. The Fuze constantly cycles from G > E > 3g and I have yet to be on a call that has not been dropped.
I'm debating returning this. While I know I can flash better ROMs to be faster, I don't know of any better radios currently to flash.

I have noticed this as well. My Fuze is very quick to changef rom G > E > 3G > H.
With my Tilt it was almost always on H especially with the 1.70.19.09 radio. All in all I do think that it could be dependent on the radio it self. I guess with time we will see if it's the radio or the device itself.

Unfortunately so far I haven't noticed any big differences between them in regards to reception. I've tried quite a few of them.
