have posted before-running darkforce(excellent)
however when abroad(sweden,spain most of europe) the phone cannot establish a data connection for either email or internet yet displays all the right signs -the triangle for roaming 3g etc
i am reposting because the last reponse was to try the latest radio 1.18-I have and still the same problem
I am with t-mobile who insist every is set up to work abroad(which it did on the original rom-but that rom was sooo bad)
all network setting are set to auto-it picks up every network going but makes no difference.
can people confirm what roms they use abroad?
what operator is their primary?
thanks
roaming- the same problem
hi!
I have the same problem. I posted a message in here, but still without any response. It is really great problem for someone, who travel all the time and cannot check his e-mails
I have this crazy issue with my D2G. I have had a similar issue in the past with all my android phones. It was worst with my SG2. It has not really been an issue up to now with my D2G but it is getting worse.
What happens?
When I call certain numbers there is no Audio in either direction, the call timer counts up and the call is in progress, just no sound in either direction. If the affected number calls me back, the same thing happens.
Which numbers are affected?
Only other mobile numbers. Always the same numbers. Always the same result. It was just an occasional mobile number, perhaps one in a hundred, but in the last couple of days BOTH of my gfs numbers are doing this and she has 2 separate numbers one attached to a D2G and one on a Samsung flip phone.
What have I tried?
Switch between Clean stock Froyo & Stock Gingerbread. Factory Reset, Wipe Cache, Wipe Dalvik Cache. Power Off Phone. Pull Battery. Nothing makes any difference.
If I pull my SIM from my D2G and place it in any other phone, the SAME thing still happens! If I swap the SIMS between 2 affected phones and try, it still happens.
**If I pull the SIM from my D2G and place it in an old Hermes I have lying around calls work perfectly in both directions.**
What works?
Calls to all landlines and most mobiles. Calling a number from the phone using GV or Skype.
Is there any pattern to the destination numbers?
Affected phones are all different brands and carriers, no pattern identified.
Thoughts so far:
It can not be the SIM card as it works in some phones.
It can not be the System version or Radio Firmware version as I get the same issue with Gingerbread and Froyo.
It can not be the cache or any settings specific to my phone.
One of the phones must be an android device.
***Ok, in testing now I just found the problem. If I have the phone set to UTMS then there is no Audio if the other phone is also a UTMS device, but it works fine if the other phone is GSM. If I have the phone set to GSM all calls work all the time to all devices.
The issue is calls between UTMS phones.
At least now I know i can always make/receive calls if I select GSM, I still want to find a solution though.
I am on the Telstra 850Mhz UTMS network in Australia.
I have had the exact same problem with 3 D2Gs. My first phone started after the last Verizon update to GB. That phone was replaced to to a failed dust seal and the first replacement had a failed BT chip. My third phone is now having the same problem, sadly. Of course I'm on Verizon on CDMA. Wish I knew what it was!!
Intermittent No Sound
I have a friend also with a Droid 2 Global
with this same issue.
Seems like leaving Bluetooth turned off altogether
has resolved this issue.
Seems like some sort of confusion when audio is
directed - perhaps audio is intermittently directed to
bluetooth when it should not be...
Any other info suggestions out there ?
Try using ShakeCall from the Market.
It should fix the "silent bug call".
It worked for me and rarely happens. Hope that works.
Please read the detailed post I made and don't post unless you understand what it implies. If you are having no sound problems because you have the volume turned down or mute enabled or you have a bluetooth bug, this has nothing to do with the issue that I have.
I have some kind of low level issue, my guess is that it is something to do with the codec selection based on the network transport type. The fact that the issue is there between 2 phones, then just changing to new Sim cards to identical carrier cards with different phone numbers, removes the issue suggests that the network is storing some information about the numbers. The fact that switching the D2G to GSM makes it work, suggests that the GSM codec is not affected.
I have my phone in GSM mode and now I can make and send all calls, but my data is so slow.
Is there a way I can force the phone to use a specific codec and stay on UTMS?
Ok, so I suspect it is the codec.
I found how to access the programming menu
On the phone's dail pad, enter:
##PROGRAM
Passcode is 000000
Most of the settings are for CDMA, under Test I can change the codec, I'll try some tests.
If anyone knows how to change the default codec let me know!
OK, I found the instructions on Droid Forums..
Pull up the dialer on your phone
Dial ##PROGRAM (##7764726)
Hit Send (the call button)
The password is 000000 (six zeros)
Select "Option 6 - Test Mode"
Hit "Next" until you come to the "Field test screen"
Under "Service Option" (top most), select EVRC-B
Hit "Back"
The phone should then reboot and you'll be all set.
OK, it seems all these settings are for CDMA, I can't find a way to access the GSM settings yet.
Thanks, mactherapy! I've made this change and will report back on whether it helps or not. Good find!! Too bad it won't help you, though.

Well... so far the problem hasn't happened again. This is starting to look promising!!!

I have recently started having this exact same problem on telstra and it is driving me absolutely insane!
If anybody has ANY idea how to fix it on GSM/UTMS please let us all know.
Ok, I am still working on this issue. I figure that if there is some way of changing the default UTMS codec to be the same as the GSM that might work. I am still trying to find the setting for this. However I was looking through the build.prop and I found some settings that seem to have an effect on other issues that I notice.
If you edit build.prop and change the line
ro.mot.phonemode.vzwglobalphone=1
to
ro.mot.phonemode.vzwglobalphone=0
then reboot the phone
The phone behaves slightly differently, the signal strength indicators are more accurate for a start.
Also from what I can see the following options are set to Verizon defaults and are only useful for people on the USA and so should be changed for overseas users..
ro.telephony.gsm-routes-us-smsc=0
ro.cdma.home.operator.isnam=0
ro.telephony.default_network= (set to 7 for global, change to 3 for Gsm/UMTS or 4 for CDMA only)
ro.cdma.nbpcd
keygaurd.no_require_sim=false
These have been discussed a few times (especially .vzwglobalphone).
.gsm-routes-us-smsc is only applicable for Vodafone NL users; for all other carriers, SMS routing is done via local carrier's SMSC.
.default_network doesn't matter at all; it determines the mode the phone starts after a factory reset.
Hey there,
Through the search forum feature I found this issue,
My phone started to do it too, i'm using GSM/UMTS, I've been using the phone since last august and untill 2 weeks ago I didn't have problems.
What I tried was>
Change simcard,
change carrier,
I was on 2.3 I SBF back to 2.2
all without succes.
I only can call one mobile number properly all others are silen,t mobile and landlines alike.
Has there been more succes to get closer to resolve this? I don't mind helping finding it.
I love my D2G and i would get separation problems if I need to change phone
In the end there was nothing anybody could do.
Fault finders at my network provider were just as stumped as me. No amount of reflashing would change anything, the handset was cursed.
I ended up having to give up on it.
The problem continues to get worse. More and more numbers get no audio either when they call me or when I call them. It only happens on the WCDMA 850mhz Telstra network.
The phone behaves normally on any other network or on the GSM Telstra network.
Re-flashing the phone with Miui or CM7 or CM9 or any of the official Motorola firmware's makes no difference. It is a truly crazy problem.
I am going to buy another android phone from Telstra and see if that behaves normally with my sim card. A non android phone I have behaves normally.
The behaviour is still the same, if I am on 3G WCDMA 850mhz on the Telstra network, someone calls me or I call them, it shows the call is connected, neither of us gets any audio, no hash, just silence. Rebooting the phone, changing the rom, factory resets, changing the Telstra SIM, nothing makes any difference. Switch to GSM only and suddenly the issue goes away.
My GF also has a D2G and has exactly the same issue and it is getting worse for her too.
I am guessing that the network is storing something like the phones IMEI on the WCDMA network and then forcing an incompatible audio codec. I don't know enough about the operation of the network to be able to prove anything.
I would like to find some way to force or change the audio codec that gets used when I make calls, is there any way to see what the phone is using for each call?
Ok, another update. I have been doing some more testing. I have discovered that DTMF tones go through to a non Android Telstra phone . Any key presses on the D2G can be heard as DTMF tones on the other phone. DTMF tones do not register on the D2G.
Between two D2G phones on the 850mhz wcdma network there is no audio in either direction and the DTMF tones do not come through either.
As usual switch either phone to GSM and everything works perfectly again.
Right, here we go.
I got a call back a couple of days ago from a tel$tra tech.
This was a long time coming and I have since stopped using the phone altogether anyway.
Basically what you need to do is call telstra tech support and go through the Indian rigmarole with technical support.
These guys will eventually escalate your problem and an Australian tech will call you back.
This person too will be completely useless but do not give up hope.
What you need to do is this: gather data.
Sit down with an internet clock in front of you and log a series of phone calls to numbers that you know the fault exists with and record the details of each failed, no-volume call and weather it was incoming or outgoing, duration of call, type of handsets connected etc etc.
Even though I have given up on the D2G on telstra and moved on, the tech assured me that he would have been able to help with this issue as he had seen it before.
Long time no post, but I found something (I think atleast)
The no sound error occurred only when I make call over the 3G UMTS netwerk. When I forced my Droid on GSM only it worked again.
Has anyone tried this too?
My carrier (KPN Netherlands) has introduced "HD Voice" for it's voice calls over the UMTS netwerk.
Might this be something? Because my Droid started to get the problem around the time the pilot of "HD Voice" was rolled out.
Hi everyone,
i did some search on this subforum in order to avoid double topics but nothing found.. so here it is:
i (and many other n5 owners) have gsm signal drops either at random times or specific actions like after receiving a text in hangouts or after receiving a call.
by lockscreen and by quick access toggles box, it displays "emergency calls only" BUT gsm signal meter stays untouched SO something is very wrong.
another strange thing is that hspa /edge data continues flowing and in my case i'm able to receive other texts even if i cant send or call..
a quick but annoying fix is by toggle airplane mode which instantly makes gsm work again.
googling this problem i've read i'm not the only one.. it seems carriers' dependent (not sim) and in my case it affects Tim Italy carrier. gonna try other carrier's sims though..
anyone of you have this problem too? any solution? any suggestion? i don't think RMA would solve the problem, just because it seems a very very common problem among specific carriers (like canadian Rogers for example)
thanks for replies
slow reaching signal
What i have noticed is that, in my office there is no signal, when i go out of the office it takes much time to automatically take the signal , i'm talking of something like ten minutes...
What I did this morning was go into mobile networks under settings and change the APN from the WAP setting which my phone had by default, to the option that says att phone. I no longer see the H but now its just the LTE appearing (not completely clear on specific differences but I know it matters to some folks) but my signal has yet to drop to "emergency calls only" like before.

this problem is kinda diffused.. maybe regards more or less apns and carriers.. so strange..
[Not Fixed] see bottom of this post.
It is fairly easy to install a new D6603 to work completly on the AT&T network. It is not so easy to find the answer of how to do it in the threads and posts. I tried many suggestions and wasted a lot of time. Hopefully this will save you from that fate.
First you must know that you can't use the IMEI number of your new phone if you want it to work completly as it should. If you use the Z3 IMEI you will have trouble with data of various sorts and the phone will go off line when on LTE after 20 or 30 minutes and you will not receive calls or SMS messages. I do not know why but it has been suggested that the AT&T network does not recognise this phone so it causes trouble.
If you have an AT&T nano-sim from your old phone then just put it in the phone. (Cut downs work but can cause other problems some say.) When the SIM is inserted for the first time into a new phone there is a prompt that asks if you want to download the APN. Hit 'yes' and the phone downloads the APN itself.
If it does not ask then go to Settings>More>Mobile Networks>Prefered Network Type and be sure LTE (Preferred) is selected. Then connect your phone to the internet and then go to Settings>More>Internet Settings and select AT&T. You should be good to go.
If you need to get a nano-sim then go to the AT&T store or call and they will give you one or send you one for free. You will need to use the IMEI number from a LTE phone that is already on the AT&T system. You can use your old phone or borrow the number from someone. If the rep installs the sim in the Z3 with the 6603 IMEI don't worry. Just call support later and tell them you sent your new phone back and want to go back to your old IMEI or have a new IMEI (from an existing AT&T phone). They will enter it and off you go. The phone from the IMEI will show in the picture on your account page. Big deal!
Update: This worked for hours last night but this morning it is back to not receiving calls. Simply turning wifi off and it began to receive calls as GPRS was switched back on. My wifi was on which has been said to cause problems. I will test with wifi off and report back. Had "no service" instead of AT&T on upper left of lock screen. A full shut down for several minutes than re-boot solved that.
YMMV. I've been on ATT with a Z3 purchased from Sony store for several months and it was registered in an ATT store by scanning the IMEI off the box followed by updating Internet settings in Setup. ATT online shows unknown model but everything works including LTE and MMS. There is something else involved when problems like this occur probably some setting not getting reset. I registered the Z3 on a new line with a new Sim card because I wanted to take my time moving stuff off my old phone--this may have avoided the problems.

I've also had no problems with my Z3 on AT&T. Works great, receives sms/mms immediately, etc..

AT&T's system sometimes takes a while to get updated with new IMEIs that trigger LTE provisioning for a users' account.
Once your account is provisioned for LTE you never have to worry about it again, but sometimes if you have a phone the system doesn't recognize, it is a pain to get AT&T to properly provision your account. Supposedly properly trained in-store reps can do it - the key being "properly trained" - Never try to do anything "unusual" by calling AT&T customer service, and NEVER use a franchise/kiosk in-person for service - make sure you're at a corporate-owned store! Even then, some stores might have incompetent staff. I've been lucky that all of my local corporate stores are pretty well staffed.
So you are saying that your Z3's with wifi and LTE on with AT&T are working as they should?
With LTE off my phone responds normally with wifi on. With LTE and wifi on it will not respond to calls after a 30 minute sleep. It does not show missed calls. Calls go straight to voice mail after 2 rings. Could you tell me what level your LTE dBm's are? Thanks!
I was told not to give them my imie# but, after recvng the minisim I had to call them in order to 'provision' it to work at all and they needed that #. I have never had any problems personally and am assuming this may be because you gave them the wrong #. Again I am only guessing. Oth, if I had had a different imie to give, I would have done so myself.
It is very strange and I am feeling it is more signal strength related than how you provision your phone. (Once it is provisioned correctly.) It seems that more people have less problems when they already have a nano-sim and just plunk it in the new phone. This might indicate that they already had a strong signal from the get go. My old HTC One + get's a better signal than the Sony in the same locations with the same (new) SIM. With the Devilcase bumper on it gets 5% less. My very limited tests yesterday seemed to indicate that it was signal strength related. I am not enough of a conspiracy theorist to imagine that AT&T would program their system to not function correctly with sims that are provisioned with these Sony phones which they are obviously ignoring for some reason. Or am I?
I had all kinds of problems with the Z3 on AT&T. The IMEI caused an issue since AT&T linked it to a flip phone and therefore couldn't provision LTE. I changed it to an old AT&T LTE device and then I was able to get LTE but was having the same issue with calls going directly to voicemail and texts showing up hours later in bunches. I found the solution was to switch off LTE in the quick settings menu. All calls and texts came through and on time while LTE was off. If I needed a data boost to stream, I turned it back on until I was finished streaming. This was while on KitKat. After upgrading to Lollipop, I was able to keep LTE turned on and calls and texts still arrived on time.
I use data rarely. Mostly wifi. If I don't leave LTE on, my phone reverts to wcdma preferred. And why can't LTE just work without me having to constantly turn it back on? What bugs me is having the APN settings greyed out. I want to be able to turn it off. If anything it seems the phone itself is preventing me from accessing the sim. It feels like I'm borrowing something which contains lots of MY private data. I know my phonebook is stored locally but I also noticed there is no option of specifying the sim or not. Anybody know how to switch APN on and off? In fact, overall even rooted, I still feel like I have almost no power over it. I can't even disable the cellular connection without going full on airplane mode and I do not trust that. I don't even fly so that needs work for sure. Dumb question but could I buy a working nanosim from say 7-eleven that my apn switch will work with?
"Anybody know how to switch APN on and off?"
On my Z3 on OTA stock Lollypop I have an icon in quick settings to turn LTE on and off. Drag two fingers down from the top of the screen. If no LTE icon then select the pencil icon at the top and select the LTE icon. There is also a mobile data icon switch there.
To turn off your radio completly you can get the Advanced Signal Status app and select additional info at the bottom and click phone information and turn off radio. Probably a number of ways to do it but that is one.
Sim contact storage was a way to move information from phone to phone. You can still do it but not really necessary with cloud backup and storage. Google does it for me without me having to do anything which I like. I still save contacts to the sim just because I can. Export and import in your contacts app menu.

Works fine here. I don't pay attention to the dBm estimates since these aren't measured with calibrated test equipment and vary widely. Those numbers are basically worthless.
The only valid comparison is data performance in a given environment (ideally a difficult weak-signal one) - and at my desk with very weak signal, every phone I've ever used performs similarly to the Z3.
"Those numbers are basically worthless."
True, but we have narrowed this down to the possibility that it might be signal related so it is worth a shot. If people whose phones are working fine would measure the LTE dBm on Advanced Signal Status at the location where their phone sits and works well the most we might possibly see some measure of difference in the phones that are not working. Most of the non-working phones seem to work sometimes so signal strength is the next best parameter to rule out. Thanks!
Here are the screen shots of my phone with LTE on, LTE and wi-fi and LTE off and wi-fi.
How do the working phones compare? Does your CDMA (voice) also go to 0% when LTE is on and GSM = n/a?
Thanks. I think adv sig nfo actually works. I'm amazed actually. I can't find the phone's native greyed out apn switch anyways which really makes no sense.
I've been using Three on my OPO for a couple of weeks now after I transferred from Giffgaff.
I am trying to avoid speaking to the support at three as they are notoriously bad. I've tried emailing them twice about settings after I searched everywhere for APN settings and advice. Eventually I managed to get a basic APN from a post on here along with instructions on how to change the preferred network type. However I am unsure I have covered everything and I have been having issues with the reception dropping out.
When it does drop out it keeps telling me there is no network (giffgaff) even though I think I've got it set up for 3, which is confusing me.
Other than the APN and selecting the network, is there a setting I've missed somewhere?
I'm still having issues with my phone dropping signal. I don't know if it is three or the phone. Is there any way to check this?
While sitting at my desk at work, I go from having H+ or LTE to having nothing with the "emergency calls only" notification.
Can anyone help?
