Does anyone else have this annoying problem of 5-6 dropped calls in a row when using UMTS with Cingular?
It seems that when these dropped calls occur it happens many times again in a row. Then, after 5-6 there will be one that works and will continue to work for awhile. I know that if I swicth to GSM this does not occur, but switching back and forth gets quite annoying.
I called Cingular about this and they added my IMEI number to my account which I didnt think would help and it didnt. I never have a problem with data on UMTS. I get a range of about 800kb-1333kb per second.
TIA
yup. i've had problems too. i just switched to GSM only, and no more dropped calls. UMTS on Cingular is not stable yet...so i'm waiting until it is more fully integrated.

I just switch to 3G instead of 2G. I want to experience the high speed internet suffing via my handset.
But I found the problem is that the phone call can't came in if I using the 3G data. Not even transfer to security services. Just a "Busy tone".
Check with the service provider and they are now checking with their technical dept to see if they can found the problem.
They said that the call should be able to come in because the phone call channel is different to the data channel. :roll: :?:
Anyone experience the same problem?
I experienced the same problem with my CHT9000. You may change the setting to GSM then call can come in when you using GPRS but you can't enjoy the high 3G speed on data transmittion. Anyone has better solution?
complicated issue; can be the same with GPRS/EDGE ; I made a lot of research read below;
http://forum.xda-developers.com/viewtopic.php?t=54738&highlight=
It is interesting. I don't have this kind of problem while I am using GPRS. But it happen to my new network provider (3G).
Lucky you then :lol:
At least you have GPRS/EDGE working and as a result it is absolutely a network provider issue.
I talked every detail with a guy in my Net. Op. and seems can be solved by "tricky switching something on" but they could not make me believe that this is not thier mistake. Because Class B phones MUST suspend the data flow and accept incoming calls for the technical point, only class A phones (no retail ATM) can make data flow and GSM talk at the same same.
GPRS is 2G, EDGE is 2,5G and same tecnique as 3G, only speeds are lower, so I beleive if u use 2G suspend while incoming calls your Net.Op. can solve the problem if they want :wink:
I have this strange problem with my vario II.
I am using Tmobile GPRS on both 2g and 3g network, If I am using the 2g phone works if If am using 3g phone doesn't work if I call it, the phone rings but doesn't alert me. The most annoying problem I am having is the phone switches between 2G and 3G if I am in a call the phone goes silent can't hear anything the display shows the call as connected and around 5-10 seconds later the phone drops call drops. This happens even if the data connection if not active.
What is the deal with that? anyone else have this problem.
Phone band settings are below
network type
Auto
GSM
GSM(900+1800)+UTMS(2100)
I've just discovered the same problem with my orange branded tytn, I'll be phoning them later to ask what they can do about it.

Works perfectly on T-Mobile UMTS for me. I did flash the Dopod 838Pro ROM though.
will flash the dopod rom in the morning. I am currently using the imate rom, and the tmobile rom the device shipped with had to many slow downs so it had to go. if this fixes the drop out issue I will be happy if not the phone will be in its box till a rom update. got the phone cheap so don't really mind. nice phone/pda apart from this issue in my line of work can't afford to miss or drop calls.
so is this a hardware or a software issue then?
No harware problem, it is absolutely software issue. Read my posts above and the links I gave
No problems here I'm afraid.
Voda v1605 running the Voda Blackberry Client, so either 3G or GPRS (where no 3G available) on all the time. Calls and SMS received perfectly.
Only issue I have is when using 3G, unlike home wired broadband, I cannot use multiple applications through the single 3G connection (e.g. Blackberry client on and surf too)

All,
Are you experiencing problems with the 3G network?
I work in the city near Liverpool Street and for the last couple of weeks I am experiencing problems when logged on to the 3G network.
For example when I dial my mobile it goes straight to my voicemail.
Some of my work colleagues are unable to connect to the 3G data network.
Anyone else experiening this?
If I switch back to the GSM network everything works fine.
I have tried ringing T-Mobile and can not get through to them,
I am using Black 2.5 WM6 and radio 1.41
Thanks
Msuk
not experienced probs
Been OK for me. I use a virgin sim but believe it uses T-Mobile network. Work in same area.
Same problem here in Manchester - 3G has been fine and rock solid until Saturday night and all hell has now broken loose....
Works OK at first, then no calls can get through - datarates are up and down like a tarts knickers (if available at all) and occasionally cell disappears totally. Move into city centre and all is well again :-/
Ruled out a device problem by trying another device
T-Mob are aware there is a problem with 3G at the moment but customer services were unable to point to a resolve time.
In the interim tho (incase you didn't guess) you can force your device onto GSM rather than 3G if missing calls is critical for you when the network's having a play up.
Hey Guys
yeah t-mobile have serious issues with the 3g network at the moment (as of this lunch time). Its there number 1 priority issue and have every one and his brother looking into it.
In the meantime, they have told me to drop my calls down to GSM - in reality this means that you won't be able to make video calls but thats pretty much it.
Start->Settings->Phone->Band-> "Select your network Type" to GSM (from Auto.
London/ Canary Wharf - same problem
Same problem with 3G in Canary Wharf in London - both on Hermes and Trinity. Switching to GSM solves the problem.
Sometimes people can not contact me.
Outgoing calls - people hear me fine, but I can hardly hear them.
Have tried various radio 35, 38 and 41. And various ROM - WM6 and official HTC WM5... Same problem.
Hi everyone,
I'm on a fringe coverage area with AT&T. I have a pretty new sim card, but I noticed that I get a lot of dropped calls while on 3G (or H). I usually get 1-2 bars on 3G. Shouldn't the call I'm on, hand-off to Edge if the signal is not strong enough on 3G? Right now, its dropping the call altogether on 3G with no fallback to Edge. Is the Xperia's radio to blame for this?
Thanks!
i dont know who is to blame but if your on the fringe as you say, you should just manually set your device to use edge/gsm.
it will save on your battery and have less dropped calls. otherwise, you phone will keep bouncing between signals.
i also have the same problem and i am curious of the answer i dont want to lose 3g all together but i have 1 bar in my house and drop calls also.
Has anyone on AT&T tried to flash their xperia with the Raphael radio? Is the signal alot better?
not just exactly the same problem here, but similar (according to the network). at home, i have no 3g coverage and manage to get edge at best, problem is intermitantly my voice stops, even though i can here the other caller perfectly, the phone still keeps between 2-3 bars of signal, and i can even stay on the call over 30 seconds after it happens. the other caller can just hear like a dead noise. the network has me testing the 3g thing for the next couple of days though.
PS. this also happened with a K850i and a K800i
At last UK O2 network pulled their collective act together and got a much needed updated ROM out for UK O2 HD2 customers. I installed it two days ago after getting it from the HTC website.
I can now say categorically that this new ROM has resulted in me receiving a significantly worse data & phone service. For the past 6 months I got an HSDPA signal whilst at home only on occasions would this drop to slower 3G strength and never to GPRS. Voice calls were pretty reliable whatever the data signal was doing.
Now I've had several missed calls - some gone through to voice mail even though the phone's showing full GPRS voice signal and my data signal has dropped off the planet - I can only get a GPRS signals now most of the time with occasional blips of 3G and HSDPA! I feel like i've gone back in time!
Has anyone else experience any O2 HD2 official ROM upgrade data signal issues? I want to re-flash back to the old 1.43 at this rate - I haven't noticed any significant differences between the two, they didn't even bother to fix the SMS bugs!
I think there's something wrong with o2 network in last few days (a week perhaps?).
I haven't changed my rom recently, but I got weird loss of services (voice and data) while the signal was pretty good. I wouldn't even realise this, but when I've tried to make a call last week (thursday or friday) I was not connected. my friend who was standing next to me dialed my number and was diverted to voicemail. wth? switching band to gsm have helped, but I had the same issue today- good signal, no voice (both ways) and data. hspa, Bedfordshire area if it's any help....
I had poor reception from o2 over the weekend... 3g was awful
Iam sim free with o2 sim back to stock rom 1.43WWE

That's interesting. I'm near Kingston, SW London - I stuck it on GSM only half an hour ago and received calls again no problem. Weird. When I put it back on Auto the phone can't hold on to an HSDPA signal for any length of time before bouncing around to 3G back to HSDPA then back to 3G then eventually on to 2G...where it stays.
Something's gone a bit wacky
My HD2 is one of the original ROM locked HD2's from O2, however I use it with T-mobile.
After installing the latest ROM from O2, no problems with signal.
It would seem its an O2 tower problem, not ROM related.
I have two units of the mi A1 both behave the same way. The unit drops signal and moves to another net and drops call.
By entering *#*#4636#*#* chose Phone Information I can choose network type.
By default it is set to TD-SCDMA/CDMA/UMTS. Since I'm in Europe I would prefer something that started with LTE/UMTS or something like it, but it doesn't make a difference. It still drops calls. And when unit is rebooted it goes back to default again.
Anyone who has an idea about the dropped calls problem?
Henrik
No one else have problems with dropped calls?
I have the same problem.
I had some kind of similar problem this weekend. The phone is up to date and worked fine for almost 3 weeks. Suddenly the phone started to drop calls like I wasn't able to place any call, also when called me back I was getting out of network message. In the mean time I was able to use 4G network placing Whatsapp calls. First I have restarted the phone, then tried to reset all network settings. Nothing helped. Then I have entered the service menu with *#*#4636#*#* and selected Phone info. Here you can set the preferred network type. I have tried out several combinations until I have managed to place and receive calls with following settings: TD-SCDMA/CDMA/UMTS. Maybe It was a network related problem, I don't know, arround me all other phones worked fine. What I have noticed, when I have placed a call the network displayed 4G and it should switch to 3G during call. No Volte offered yet here so it must place a 3G call. After playing with settings this working as it should.
Did the settings save after reboot? I'm still having problems.
I still have TD-SCDMA/CDMA/UMTS after reboot. I don't know what were the default settings.
Henrik, did you come up with a solution? Fellow Scandinavian here with the same issue...
Somewhat strange... I'm using my A1 in Sweden as well.
During quite long calls (10-25 mins) I haven't had any 'dropped call' this far.
I'm having 2 SIM cards (1 private, 1 work) in mine, both Telenor.
Edit:
On Stock 7.1.2 Dec 17 ROM, not modified/unlocked or rooted!
Hey fellow swedish,
I am also considering to buy that phone.. Did you manage to find any solution? Do you think that worths it buy it?

I think people in this thread have some ****ty MVNO with service from several carriers, and when the mobile switches carriers, calls drop.
If you're in a major carrier then such switch never happens so there are no dropped calls.
But I might be wrong of course.
That's weird.
I noticed that whenever I'm on 4G the calls usually drops out. If I have it set to 3G I don't seem to have any issues. I tried to set it to LTS/UMTS auto (PRL) but it goes back to stock setting when I reboot.
I had a Sony Xperia Z3 Compact before and I never had any dropouts so I don't think it's a carrier issue... What does yours say in the Phone info JockeSve?
Voice network type: LTE
Data network type: LTE
Set Preferred Network type: TS-SCDMA/CDMA/UMTS
it is dropping the calls... is it phone? or just toy?
