Calls not getting through?

Hi,
I'm running my desire with rooted stock rom by oclock (called 3'oclock over at modaco).
Also running a2sd with richardtrip ocv14 kernel, and radio is 32.30.00.28U_4.05.00.11.
A lot of incoming calls are not getting through - sometimes they do, sometimes they don't. People are saying it goes to voicemail 2 or 3 times before it come through. I don't see missed calls on my phone when this happens.
This is with mobile internet set to off, so it isn't that.
Anyone else have this issue? And know how to fix?
Thanks.

Is it possible you could try flashing a differnet radio perhaps?

Are you on he boundary of your network's 3G coverage?
I find I often have to set 3G devices to 2G only in my house because the 3G coverage is marginal and the phones spend half their life jumping between HSPA and EDGE, and it often causes missed calls as you describe. Nothing exclusive to the Desire though, the only 3G device that never had a problem here on O2 was my old TyTN, and that was only because the radio on that was too rubbish to pick up a 3G signal at all here

It happens with my internet set to off though - haven't had mobile internet enabled all day just too see if it was this but it happens when the internet is off.

Your phone will still connect to 3G networks if the data is off. Try changing 'Network Mode' under 'Mobile Networks' to GSM only and see if that helps.

Will give it a go - hope not though cos i like using 3g for emails, surfing etc.
Will also try disabling the "enable always on mobile data" setting to see if that is doing it.
Thanks for the info.

I had exactly the same problem when I used the built in widget to turn OFF mobile data (I had a stock orange ROM in UK). I did this to save battery, but calls did exactly what you said. I now leave it on all the time (and actually battery has improved massively in my 4th week, dunno why, but I went 2 days without charge, and quite reasonable usage!)
Now I leave mobile ON all the time it works no problems, and haven't had the same problems since!

[Q] Data connection problems

Hi,
I have some data connection problems since the first day i bought my DHD.
The phone reception signal bar are always changing even when i am not moving at all.
It can generally move from H to 3G a few times, then go to E and then G, in a few seconds.
it always moves, my internet connection is very slow.
It's as if the radio was always trying to renegociate the method of communication (GPRS, 3G, etc) with the operator's antenna
When i am in a phone call, i got disconnected sometimes or the sound stop during a few seconds (the time the radio switch from 3G/H to E/G i guess)
When i disable WCDMA from the settings i get a quite stable sound during my phones calls (maybe because the phone no more tries to negociate). But for Internet... it's just slow.
I tried a few ROMs, and their respectives radio rom (the one with the IRL branded in the ROM) i sometimes thought it was better but always it's still too unuseable.
I tried my SIM card in an iphone 3GS and i am usually in Edge (sometimes 3G) but when its 3G i can surf quickly during hours (if i don't move). This is not the case with the DHD.
btw i am on the french carrier SFR
If any of u had any clues i would really appreciate your help.
Thanks you

what rom are you using and what radio and ril................... now what radio are you on now

OP already stated he tried numerous ROMS and their cooresponding radios. Sounds like the signal is that degraded that any radio/ril combination will not help.

Thanks for your replies.
As said i tried many ones with their respective recommanded radio.
I am actually trying Radio_12.62.60.27_26.13.04.19_M with Android Revolution HD 4G_6.1.1 with no sense script.
Are there tests i could do to identify if its a hardware problem (like standing in front of an antenna and running some special tool maybe)
Btw, i also tried :
-RCMix3D_Runny_v1.3 but does work with internet pass through (wich is really important since i can't use internet from my phone carrier...)
-niarkMIUI-3.9.1
-LeeDrOiD_HD_V4.0.0-SE-3.0-BETA with Radio_12.54.60.25_26.09.04.11_M2
-cm_ace_full-203 with my stock radio ROM
-virtuous_unity-v2.37.0 with i don't remember wich one...
P.S : i would be Glad to test any ROM / Radio combinaison you would suggest me.
Thanks by advance for your attention

if you tried all those roms and diffident radios seems like its more like a hardware or provider issue does it happen off different towers or maybe you can go to one of the stores and try the phone at the store with yours at the same time?

Thank for the advice indeed i need to try this.
Do you know what i need to revert back for the tech not to tell the waranty is over since i have flashed my phone ?
Does i need to reflash the recovery etc? is there some tutorial in this subject because if i go to the store with my custom rom i guess i won't get too much help :/

Don't even take out your phone, your going to say your just looking, don't show anyone your phone, they won't even know what to look for, just test your phone to the one at the store, make sure apn's match. But if you return your phone you'll need to ruu back to stock. You can search easy s-on

What happens if you manually select 3G only, or 2G only from the settings menu? Does it just lose signal, or stays strong?

Hi
If i select 3G only
I first get no reception (as if when switching from 2G to 3G the radio had to restart)
Then the 3G signal appear strong, decrease slowly in less than 30 seconds, and after all, it seems quite stable.
The bandwidth is good i am downloading fastly
(i am commenting in real time)
Still no deconnection.
I will try it during the whole day and tell how it is behaving.
umm during a few seconds, there were no indicator (no 3G or H), just 3 bars.
It then restarted in H with 1 bar (i am not moving at all)
What will happen if i have no 3G in my area ? I won't be able to receve a phone call ?
Thanks

If you force it to 3G only, and you move out of 3G area, then you should either get a no signal indicator, or if you have roaming enabled, you would get the roaming indicator. I'm curious now because as you said you aren't moving, and it's still changing. That shouldn't happen. Hmmm

[Q] t mobile h+

Ive recently attained a captivate glide and unlocked it to use on t mobile. Like you would assume at first glance i had an edge connection. Although after messing around with it i realized by going to
Wireless and network > Mobile networks > Network operators >Default setup > Manual it gives me the option to choose to connect to att/ tmobile and when i chose tmobile and it registers on the network i get H+ speeds for a few minutes then it just defaults back to edge
is there a way i can keep my phone on H+ at all times because its capable

bump!

I have this problem too, but only into my house. Outdoor that´s right. I´ve tested with all modems, and I think the best for me is i927UCLH2.
Which rom, kernel and baseband do you use??

I´ve done some tests with my glide and my mother´s galaxy chat, in different places. In the street I have H+ and she H, but when we are into any house, under any roof, she still has H, and I only have E.
Does it happen to you?

shmemse when

Doesn't this just sound like a basic signal issue? When the signal gets worse (indoor vs. outdoor) it will drop down to a lower signal.
Also, are you sure Tmo has fully rolled out the 1900mhz band in your area? They may not have complete coverage yet.

i'm sure that it is a phone or a software phone problem, cause i've put my sim card in my last phone (xperia pro) and it has H signal too
i've tested all rogers and att modems, and still have the problem..

Hi, I have a similar prob, I'm in the uk and need it to stay on H+, as it'll drop off to 2g in the house, I've always used miui roms in the past and they have the option to force 3g etc. The only way round this I could find is to use 'pimp my rom' which allows you to select which network you want manually, such as gsm, edge, wcdma etc. Download it, go to tools, device hidden menu, turn off radio, wait, turn radio back on, then quickly select from the drop down box what signal you want, I select wcdma only. If the radio does not come back on, put on flight mode then off again, and will work.. bit annoying but works..

That happen to me too, but not for t mobile, for a operator that use 1900mhz in my country.

strange network problem

I receiven a m919 with strange network behaviour
I used a profesional tool : Octopus Box Samsung to repair EFS and NVM Area, I unlocked again and phone started to work decently (not as expected) after 1 or 2 days the phone came back as in the initial day.
To explin better:
it always says searching, but it do shows 3 or 4 signal bars, if you find network manually it finds the network but if you try to register it give error registering on network.
I dont know what else to try
when I repaired everything with the tool it started to work well, but indoors it had no network or dropped calls, usssd codes failing, etc.
outdoor it worked fine but as I said only 2 days.
in my counry there is only one network and it's 2G/edge not 3g or 4g here.
is there any trick to make these phones'modem work only at 2G mode and never try to find/connect/switch to 3g/4g/lte. etc? maybe this could make phones work nicely on 2g networks?
I have noticed most 4G/lte phones has poor signal reception here in my country.

No signal when use 4G network for a period of time

I just changed my SIM Card from a 3G SIM to a 4G SIM recently. However I met an issue, whenever I use the 4G Mobile Network for too long (like 1-2 hours), the phone will suddenly lost all signal for 5-10 minute before recovering the signal. The signal bar is empty, and it appears the "Emergency Call Only" stuff. Is it just me or everyone is encountering this problem?
I have no problem at all when restrict the phone to connect 3G/H+ network only, it only occurs when I connect to the 4G network for a period of time.
My friend that uses the same telco with me doesn't have such problem (disconnecting/no signal at all) when connecting to 4G network, and it doesn't seems to be the antenna problem since the problem does not happen when I connect to 3G/H+ networks.
What might likely be the cause? Is there any solution to this?
Sorry for bad English, not my native language
(I live in Malaysia, and using UMobile Telco. )

Now that you mention it, I have pretty much the same issue of losing signals, and the problem hasn't occurred ever since I stopped using 4g. I didn't notice it was because of that, because I changed the phone too while changing the sim. I have marshmallow by the way. Don't know if that might be linked to the problem.
