[Q]No 3g Signal, only Edge, help - Defy Q&A, Help & Troubleshooting

So I got this phone from my friend asking to help him because quite recently his phone would start dropping calls and losing signal. He was running completely stock on Android 2.2 He asked if I could take a look and try to get it working. So after doing some researching in the sub I found the rooting app and decided to put CM7.1 on his phone. Everything works great now considering he couldn't get a call to go through but it only has edge and that's only after waiting a couple minutes after boot. There isn't an option in CM7 to choose WCDMA but it does have the check box for 2g only. Anyway calls go through fine now as well as texts but god Edge is so slow. WiFi works fine as well. Anyway What on earth do I do to get 3g working?
I have also done the Defy Baseband switcher, everything but T-Mobile 3.4.2 -107-9 works. The only thing I can think of doing next is having him switch out his sim card through T-mobile. If someone else has an idea I would love to hear it cause I am just spinning my wheels.
Also I did install CM7.2 and it had the option for WCDMA which forced the 3g icon but it never would do anything about data for it. It would just sit at a webpage and timeout. Anyway back at CM7.1 and waiting to see what happens.
Thanks ahead of time for the help guys.

Anyone with any other ideas or something simple I am missing?

I have a very similar problem. I have installed WhiteRabbitEddtion 1.5 for Defy+ MB526 (based on CM7.2 I think). When it tries for operate on 3G, it works for a while, then just loses the network. It looks like the receiver goes deaf or something. If I select 2G only, it seems to work fine. But then restricted to EDGE data rates -- bummer.
My network operator is Telstra (Australia) - 850/2100 MHz.

X1i when using 3G on AT&T I cant make or receive calls???

So when I leave all the band settings to auto on the phone, it immediately connects to AT&T's 3G network and shows the "H" in the title bar it worked for a little while then calls stopped coming through, after a hard reset it works again with calls for a few hours, then it begins to fail.
If I switch the bands to GSM and manually select the frequencies (850 + 1900, according to wm) then it connects to the EDGE network, and I can make and receive calls as I please, no problems, except for the crappy network speed.
So someone help me out here please, is the phone defective, or is it not working as it should because of the lack of the 850 band? I know that AT&T works on either or but this problem has me stumped.
Other than this rather huge problem (phone that cant make calls), I absolutely love the Xperia and would hate to return and wait for another.
did you try to use the connection wizard to let the phone config itself?
after I put my iphone sim in it shows the H/3G icon on anf off all the time, while I can receive call I was unable to go online.... after someone suggested me to call att to update the imei on my account to the x1, I found that I still have to go to connection and change the setting myself b4 it can go online. you will have to remove the user name and pw in media net setting and uncheck the proxy server.
I guess my case is a little different than yours but I guess you can give it a try... good luck =)
Thanks, I actually haven't tried that since i figured it would be the same as what happens when you turn the phone on for the first time, when it autoconfigs.
if it say it detect a new sim and ask if you want to do the auto config then I guess its the same... but again I did need to change some settings inside the network config to make it work too... so I am guessing the "auto config" has some flaw in it
No problem with my X1i when I venture in a1900mhz area close to my home. I live in a small town in Ca. only 850mhz here. But in the larger Metro area around me... No Problems with calls or hspeed data access...
Stuart
Thanks for the replies, It looks like the Configuration wizard in the settings menu did the trick. It do something else that the autoconfig doesnt. The phone seems to work now just fine, although it doesnt hang on to the signal as well as my old k790a. The office I work in is an ATT dead zone and I could make calls using the K790a with only one bar, with the Xperia it either doesnt go through or drops the call.
Again this is better as it works now, just not as well as my old phone.
Also, scl_electronics, so you are saying the X1i has both 850 and 1900mhz bands? I had a feeling mine did too, but I thought it was put to rest that that wasnt the case with the X1i....
Sorry Aaron J,
i should have been more specific!! Where I live, 3G is only on 850mhz band so I don't get access..Just The edge network. When I venture about 10 mile away toward the major Metro areas..The 1900mhz band are used. So the H is displayed, but I don't have those access problems for calls or data!!
But i am waiting to see if they can crack the rom for 850mhz-3G access!!

Oh ok thats kind of makes, sense although I thought the X1i didnt have an 850 band at all, so what frequency does it work off then?
Anyways, back to my problem....I spoke too soon, it dont work on 3G switched to EDGE. I might just try getting a new sim card, mine is a Cingular one from 2005, that has been in at least 4 different phones now including the X1i.

Well out here in Ca... 850mhz gsm/edge is used ..So I quad band gsm phone is handy!!!
Stuart
Yes it is! My little problem is a little confusing though as one thing I just realized that I didnt say before is that the phone has no problem connecting to the 3G network using HSDPA. I get full bars with the H icon pretty much everywhere in my area and my data speeds are very good. So I can surf the net, download programs, watch high quality youtube videos using the app in touchflo and even send and receive texts just fine.....just no calls when on 3G. I'm hoping its just setting somewhere and not a faulty device.
I live in Raleigh NC by the way so maybe it could be a faulty tower?
Well when venture into Stockton Ca. my phone switches to 3G-HSDPA:1900MHZ Without a connection hitch....
Have you tried a soft reset......
But when all else fails Hard Reset to the Rescue!!!
Btw... in several of my ppc-wm units when restoring to OEM setting(hard reset) there has been many time the process had a problem. So something would be screwed up!! So when You don't succeed, try another hard reset!!
Good luck,
Stuart
hey i was wonder if your problem is HSDPA/HSUPA being on, i have at&t also and it worked for the first few weeks fine with it being on then all of a sudden it stopped and couldn't connect to the internet, before i had the H/Edge showing up and also my email never updated when it was set to do it every 15minutes. Now that i disable the HSDPA/HSUPA i see 3G/Edge and email update all the time on the X1i. Just wonder if that might fix it, I'm all kinda still new to all this but i had my X1i for 2 1/2 weeks now.
Hello thanks for all the suggestions, Experiaenjoy, no I haven't tried mainly because I can connect to the data network just fine and get awesome speeds with full bars pretty much everywhere, all of my data related activities and programs work just fine (aka murder my battery life ). I just cant make calls while on 3G.
I talked to a coworker today who used to be a regional manager at AT&T hee said that he saw many cases of people who were having problems where it was due to the SIM card. He said they all had the older orange Cingular card and that an update to the new blue AT&T card solved all problems. So right now I'm trying to see if I can get mine updated (I do have an older Cingular SIM). Once I get that, I will do a hard reset (3rd one also done about 20 soft resets since I 've had it-I've installed a bunch of programs and tweaks) and skip the auto config and go straight to the connection wizard.

[Q] Orange/t-mobile network sharing in the UK

Hi All,
Done a quick search on this and can't find anything relevent, but i apologise if a thread already exists.
Really a question for those in the UK on the t-mobile network. Have any of you attempted to sign up for the orange 2g roaming service yet? I signed up, recieved the confirmation text, replied to it, and received the final confirmation. However, I'm not sure it's working. The signal seems no stronger, and i still drop in my house.
Obviously i'm posting this in the android section because i'm running android myself and am wondering whether anyone in the same boat has managed to get roaming to work. Should the fact that we're on a non-official OS running off the sd card make a difference?
Oh and for completeness, i'm running shubcraft 1.5 rmnet.
Cheers fellas!
I'm quite happily flip flopping between Orange while at work and T-Mobile for everything else...
works like a charm for me though you do have to stick the phone into Airplane mode after selecting the different provider for the data to work ...

Many thanks for the reply Jezwick. So, just for clarity, you're manually selecting each provider as and when required? Because i can do that, i think. When i select orange though, whilst it registers with the network fine, i get a little "R" above the signal bar (any ideas what that means?) And the speed appears to be limited to Edge. Orange have a very strong signal round here, so i figure i should be getting GPRS really.
It's the auto-switching i'm not totally sure is working really. Is there any explicit indicator that it's flipping on it's own? Or do you just observe a generally better 2g signal, rather than say, a very weak 3g one? Round the house, my phone is still trying to make do with 1 or zero bars of 3g. I would have hoped it would flip over to orange more or less all the time under those circumstances. Nothing to stop me manually selecting it i guess though...

The R is indeed for roaming that's the way it works if your not on your 'own' network.. The 'flipped' service will currently only work at GRPS speeds at the moment but should be 3G by the new year
I have noticed mine flipping automatically but only once or twice in the last few weeks but only when I get NO signal from the current service.

Understood - thanks for the info Just done some reading and apparently EDGE is faster than basic GPRS. For some reason, i'd always assumed the reverse. Looks like the best option is just to have it always on orange whilst at home and use wifi for data (which i do anyway to compensate for the poor signal). Cheers!

[Q] Poor 3G to 2G handover

Hey there, I enjoy reading this forum but I had little to contribute with as I am an android noob. So unfortunately my first post is a question forced by the fact that something is wrong with my DHD Thank you in advance for your advices!
The problem is - when in areas with low 3G coverage the phone keeps on searching for 3G for too long instant of seamlessly switching to 2G, which often has full signal bars. This way the phone acts as if there was no signal and sends incoming calls to the voicemail even though all it has to do is to switch to 2G as soon as 3G gets too weak.
My previous phones had no problem with this. In my city the 3G quality varies from area to area but the 2G coverage is perfect almost everywhere. So I used to be sure that my phone never really disconnects from the network, it only might have dropped the 3G signal in favor of 2G while keeping the calls and everything.
I know I can disable the 3G and stick to 2G and EDGE but this way using full data capabilities of the phone turns into pain instead of pleasure.
Just to make sure and to show I did my homework, this is NOT:
- the death grip case
- a network related problem /I suppose.../
- a problem with data connection /I have never run into any problems with this/
My questions are:
- is anyone of you experiencing this?
- is there a way to force the phone to hand over the connection from 3G to 2G quicker without "blind spots"?
- does any custom ROM improve this? /I am running the latest stock HTC DHD android 2.2 with Sense/
- is there any hint that android 2.3 gingerbread should fix this issue?
Thank you, hope to find a piece of good advice here!
I`ve found this service menu and I switched the preffered network from WCDMA preferred to GSM AUTO PRL. will see if it helps.
I havent noticed any more problems since I did the switch. I think it helped. I cannot be 100% sure but I think it did the thing for me. I forgot to mention that I also switched networks mode from Auto to European but I think this has nothing to do with the issue.
fortuneman had my answer. To access the service menu on the soft phone keypad enter *#*#4636#*#* and its under Phone Information.
Switching from 2g to 3g works seamlessly. But the other way around doesn't work that well. Nothing to do with the phone. Just the net tech that has its flaws. If your in a call and switch to 2g, the call will most certainly be disconnected.

Not longer seeing telus

Hi All,
Not quite sure what happened here.. Upgraded to latest nscollab yesterday, everything was working fine. Decided to try the "Antennas" app to see if it'd show where the towers are near me, switched to 2g mode, played around with it a bit, switched off 2g mode and now my phone does not see telus at all. When I go into search networks, telus simply doesn't show up and my phone stays in emergency mode.
It sees rogers fine and is able to connect to rogers with a friend's rogers sim. I've tried my telus im in other phones and it works fine, other people's telus sims in my phone don't work either.
I've tried reverting to an earlier backup as well as going back to a stock backup. I've also tried reflashing both the kb1 and kb3 radios, no luck.
Anyone know what might be the issue here?
both Telus / Bell do not have 2G
they only have 3G, as in the VOICE only works via 3G
it was the same using the SGS i9000
Did the rogers SIM work on 2G (Edge) only? I am guessing Rogers and Fido will work, but only on 2G
Same happened to me, on Fido, my phone could no longer connect to 3G...Only 2G after playing with settings. I returned the phone
The reason why Telus-Bell SIM would not work at all at this point is that they only support 3G...
That makes sense, but i don't have it set to 2g mode anymore. It should be seeing 3g just fine.

Just tried that, nothing. I think that's the same as a wipe data in recovery?
I've tried:
- Reverting back to a stock backup
- Reverting to an earlier working backup
- Doing a factory reset on both of the above
- Reflashing the radio on both

This just happened to me, I switched to 2G and got nothing but com.android.phone quit errors, now I can't get back on 3G. Flashed radios, data wipe, everything... wtf... it's back to stock now and still can't get on Telus... double wtf...
Christ... finally got it... my head hurts from all this reading
For some reason it was on the wrong band. Do this in dialer... *#*#4636#*#*, phone information, menu, select radio-band, USA, and should work make sure its on WCDMA preferred as well under phone information

I had the same issue when in Canada, and forgot I had the band set to Europe (my region).
I set it to Automatic detect, i know catching signal will take longer. But then I dont forget

i had the same problem since may 14th (sat), thanks for the fix!!!!!!!
Same thing happened here, same solution. Glad you stumbled on it too!
As the title says, had the same problem on my Nexus S (running on Bell), I believe manually switching the 2g/3g toggle in cyanogenmod rom accidentally is what set it off.
Glad you found the solution!! Was maddening for me; knew there must be a way to fix through the UI, but until I fond it, phone was a wifi mp3 player :/

Bad Reception with this phone?

Hi,
Was wondering if anyone got bad reception with their phone. I tried 3 different carriers since I had my ideos, in neither of them I ever had very reliable reception and lately the problem is getting worse. I'm running aurora 4.1a and I loose reception all the time, and the battery drains so quick because it's always looking and looking. My sister, my mum and my dad all have good reception (2 of them with my old carrier and 1 with my current carrier).. I can put my dad's phone (same carrier) next to mine.. he will have full bars with 3g and I'll have no reception at all!!!!!! Then it connects and disconnects again, and so it goes... Anyone having such issues?
Thanks.

I'm having the same problem, I'm running Aurora ICS. I use to always have good reception everywhere, Then suddenly I've just been unable to. Any help would be great! If I do find out any fixes to the issue myself I will sure let you know.
Good to know that I'm not the only one! Thanks. Hope we find a fix soon.
I've fixed mine now, What I've done is I've gone into Settings > Wireless & Network > Mobile Networks, and scrolled all the way to the bottom, and simply re-registered on the network and selected Use only 2G Data. Mines now working fine with full connection everywhere. However I don't know if our problems are exactly the same, however this is what fixed mine. Sorry if this doesn't help.
I have the same issue. Mine connects to 3G and has good connection, but then it simply disconnects and moves to 2G or reconnects to 3G some time later. That happens pretty frequently and I thought it was an issue with the carrier, but now I am not sure anymore.
Blefish, that is EXACTLY what happens to me, and I tried 3 major carriers in Australia (the only 3 that have their own actual towers). Just after I posted this thread, I happened to do the same thing as IwAsBlack recommended and... so far it seems to work. I have generally better connection and I haven't seen that ugly no reception icon since! Of course, internet browsing will be generally a bit slower but then again, it's better than staring at the phone for 3 minutes until it reconnects just to open Google.
You haven't stated which model you have. I got rid of a Motorola Bravo for at U8800-51 and I have excellent performance over AT&T (US). Crystal clear even with only one bar and I have never had a dropped call.
Have the same issue on any ROM with any mobile network in Belarus. Can't use 2G as recommended above 'cos of a huge use of mobile internet for some net-radio.
Sorry for bad Eng.
Its a U8800 Q&A forum, I didn't think that I had to state the version since I have a U8800.
Yesterday I tested and kept an eye on for the whole day! The reception since changing to 2G only has been AWESOME! Only had a drop out when I was in the subway (of course!) but aisde from that, I had amazing reception not to mention.. that my phone lasted the whole day with still 15% left!! (3G on, it would have to charge it twice while I'm at work) So, it fixed my reception AND my battery problems.

FYI, Ideos X5 U8800 describes four different models.
I know it does. What I meant is that I have the Normal U8800 model, so I didn't feel like it was necessary for me to point any variant model number like PRO or 51 or H, because it's STANDARD U8800
So we can make a conclusion that U8800 does not operate well on 3G. I can't switch it myself because I want to use internet too. And I am pretty sure we can't do anything about it, no matter if the problem is in hardware or software.

Mate, if you switch to 2G you will still be able to browse the internet! It will only be a LITTLE bit slower, better than having constant disconnection!!! I constantly use the internet to sync my gmail, send free texts, browse the net and a bunch of other stuff.. works even better on 2G with constant reception, not to mention the benefit of the phone battery lasting a whole day (AND still have internet).. so switch to 2G and you will like it... still good internet only with better reception
Same issue
Having same issue when using GSM/WCDMA auto or preferred modes. works normal on GSM network only.
Even when I have no signal of 3g, gsm is working in the background.
problem arises when I have a call, 3g signal drops to minmimun, after the call phone tries to reconnect with the 3g signal but drops the GSM signal in the process.
Try this , as soon as you disconnect the call, try to call yourself from other at that instant only. Your phone will be shown unreachable because phone drops the GSM signals.
