N1 on Three (3) UK? - Nexus One Q&A, Help & Troubleshooting

I've just moved to 3 in the UK (from vodafone) and I can't get a data connection - I get the error "Data connection lost" reported on several threads here, however my old vodafone SIM (which runs out on Tuesday) runs perfectly fine on 3G
on 3 the phone test (#*#*4636*#*#) shows HSDPA connection and the ping test FAILS (with no response)
on Vodafone I'm also on HSDPA - but the ping test succeeds
I'm on
stock Froyo FrF91 -
rooted and unlocked
32.36.00.28U_4.06.00.12.7 baseband
and 2.6.32.9-27227 kernel
So
Anyone have a clue what the issue might be?
If I can't get this fixed I'll have to move (AGAIN!) , off Three - and onto somewhere else. I'm sure there are other 3 users with N1's!

More bizarre
OK - this gets more bizarre - can anyone explain this?
Take my 3 SIM to 3 Shop - plug it into a 3 branded HTC wildfire - and it works just fine. Use their 3 SIM from the HTC wildfire on my machine - and it work great. Plug my sim back into my N1n- it works just fine now. #*#*4636*#*# actually resolves my pings and get great transfer speed
All smiles
Drive home - check again - no name resolution occuring - no data download. still on HDSPA
:-(
WFT is going on here!!

Hello,
I'm on Three with a N1 and unlocked custom Froyo Rom. Works fine for me. Question, are you getting 2g signal, can you make calls etc, is it only 3g you are having problems with?
Are you sure there is Three 3g signal in your area?
Settings>Wireless and Networks>Network Operators
Can you see it there?
Have you tried resetting your APN settings to default?
Settings>Wireless and Networks>Access Point Names>
Menu>Reset to Default
Let us know how you get on.
Cheers.

Have you tried "WCDMA Only" instead of "WCDMA Preferred"? Works better on 3 for me anyhow in Ireland.

Well on the stock froyo rom it doesn't differentiate between 3G and H,but I always get 3G displayed - with 4 bars. Can make calls - no problem
The diagnostics always shows HSDPCA (or whatever!)
however it won't ping or resolve from my house
I drive into town (1 mile) - and it works
I guess its a reception issue??
Phone physically gets hot with the 3 SIM in - at my house - and battery life is appalling (3 hours to flat) - so I guess its trying really hard to connect.
I defaulted the APN again and selected EURO band only - and still no luck. No data connection from my house.
3 network coverage map says I have good coverage - and (as I said) 4 bars in signal strength.
Odd

Set WCDMA Only the same menu you chose Euro Band from. It's a dropdown box.
It does sound like it could be a reception problem all right. There's also a new radio available which might provide stronger signals. Worth trying that too IMHO http://forum.xda-developers.com/showthread.php?t=723839

If u have 2g to make calls and Wifi for Data, then you might have to settle for that I guess, if your phone works 3g in one area and not another, I would say reception issue, do any of your mates have a Three phone they can test at your house?

Here's another tip, try the following...
Menu > Settings > Wireless & networks > Network operators
Select "Data roaming"
Choose "Select automatically" instead of 3
See how that goes.
PS I'm now using the new radio 5.08 I linked to above. Looks like I'm getting a stronger signal.

Kaiser keeps switching from 3G to Edge

A friend of mine just purchased the Kaiser to be used on the at&t network. He lives in a 3G area in the USA and for some reason, his phone will not hold the 3G connection. It wants to switch to Edge. Is there a manual setting to stop this from happening or a new utility to enable/disable certain connection. Is this normal for 3G to do this. Any information I can pass on would be greatful.
Thanks
I think it's an indication that 2G is stronger than 3G in your area. My Kaiser always hold 3G connection all the time where I live. You can "manually" force 3G. Here is one the many ways to do it: on Windows Start menu, go to "Setting" then "Phone" (on the "Personal" tab), click "Band" tab, then use "WCDMA" for network type selection (default is "Auto")
Thanks for the help. I'll pass it on.
While the Kaiser is my first ppc type phone and I cannot claim to be expert I do think that this is a normal reaction of the phone to what networks are available.
I live in San Jose Ca. and must, perchance, move up and down the peninsula in the normal course of work and life.
I see my Kaiser switching from Edge to 3G to unnamed all up and down the peninsula. It is best for 3G in the cities and worse up in the hills -as one might expect. I also get the best 3G connections in the evenings and night vs. the daytime when, I assume, more 3G users are taking up bandwidth.
It is unfortunate that where I live is an Edge (during the daytime) area though I am paying for the 3G data plan.
3G issues with the TyTnII
Hello all:
I post on the AT&T HTC forumn and had this thread sent to me by another poster there.
I also have a TyTnII newly aquired from MobilePlanet on Weds. I am having the same issues with 3G. It briefly flashed the G icon on boot up then switches to Edge with all 5 bars. I've tried the manual mode fix, no luck. The wcdma gets no signal and the gsm goes back up to 5 bars same as auto.
Then theres the inability to register my serial # on HTC's EU site. Says SN is invalid... MP has had several reports of EU devices doing this.
I'm in the US, NorthEast NJ area. And in the middle of a known 3G area.
Bill
Can anyone help Bill out? How many of you CAN use 3G on the USA at&t network without a problem? He's trying to see if it's a setting issue or a phone issue. I'm not in a 3G area so I can't help him here.
Thanks

I get a 3g signal when I go into Philly (I live about 45 minutes outside the city) It holds it just fine as well. Is it possible you just have weak 3g coverage where you are? I actually shut off the 3g on my phone as I have no 3g coverage at work or at home and the 3g connection discharges the battery in a hury.
I'm on AT&T as well.
Oh - BTW - I also can't register my phone with the eClub either. I sent an Email to the HTC Webmaster but have not had any reply in 3 days. I'm not too confident in HTC's support.

Desperatly need help getting 3G instead of E

Hi guys,
I brought my first xperia from my phone serivce provider, and it always had the "3g" symbol at the top. However, when my xperia broke, I had to buy another one and got one of ebay. Since I brought the new one, my phone always has the 3 on top. I'm currently using the firestorm valkyrie rom which as the htc interface. When I go to the data connections it says an option (3g) "change to gsm mode" and on is selected. Even when I toggle that, it still always has the E symbol. What do I need to do? I know my sim card is cabable of getting the 3g. But this is a real pain because every now and then my phone just doesnt receive service, so I constantly go onto the comm manager and then it seems to just click that there's service and shows 2-3 bars. Then all of a sudden again after a while there'll be no service. So I'm guessing that's because of the E thing. It shouldn't be my current location as I've never experienced this before.
Is there a setting I can go to to get the 3g symbol? Or a patch I might need for the phone?
Please help
Kindest regards.
You need to change while the connection is not active, I believe. Or... you got the Xperia version incompatible with your network... Or... the ROM is buggy, try another.
sorry, I need to change specificially what when the connection is not active? Say you mean, turn off my phone settings and not connect to the network and then adjust something? It is not the rom. and the seller on ebay has stated that it is a 3g phone - many others have brought it as well with no complaints.
3G settings on x1
Hi
For some reason your phone is only camping on the GSM network (G or E indication depending if your carrier provide GPRS or EDGE on the GSM) instead of the 3G network (which you have been using before).
In settings, communications you should be able to set "3G change to automode" to on,
When this is set your network provider will tell your phone to use the 3G as preffered network, but when coverage is not good enough it will drop you back to 2G (which has a better reach due to lower frequency band).
If it does not happen automatically there might be another setting that is wrong,
goto settings, all settings, personal (tab), Phone.. then choose the "band" tab (need to go to the left with the arrows) , then you have the dropdwn lists to set:
select you network type (need to set auto or wcdma to get 3G)
select your GSM/UMTS band (need to set 900+1800 for europe, 1900+850 for us, dont know who is using 2100+800)
once changed the phone will restart the phone part and search for your carrier in the right band.
good luck
Hi,
Thanks for your reply. I had changed the automode to on. But still had the E.
I went to the setings, and band tab, and i had selected:
Select your network type:
(blank)
Select your GSM/UMTS band:
Auto.
I changed the first oen to auto, and as for the last, here in Australia I'm with Tesltra which is 850 UMTS? I think I read online. Anyway it didn't have the option in there, so I went through them all but wouldnt get service at all except for the first: GSM (900+1800)+UMTS(2100+900). and Auto. I think my last experia might have had auto for all of those too. Anyway with those only two options working, I still get the E icon. Even tried setting aeroplane mode on and then off to see if it might register, but it didn't.

I see , Telstra is one of very few networks that use 850 for WCDMA so they might be using a different RADIO ROM than the rest of us
I saw in the thread below that there is a TELSTRA AUSTRALIA (1.03.841.8) R2AA008 version..
http://forum.xda-developers.com/showthread.php?t=477801&highlight=telstra
you probably need to flash that one to get the 3G working on telstra..
3 is using the normal 2100 so you could also try with their SIM just to check that there is nothing wrong with your hardware..
Sorry for the late reply.
I have realised that i'm in an area that doesn't support 3g. however my last xperia phone which I brought from telstra was the x1a, which had the next g network - hence I got the 3g symbol. However I have found that that I have the x1i, which doesn't list that network. I rang up telstra, and they transferred me to the sony erricson call centre, and they said you can try and do an update but it is not gaurenteed to get the next g service. I have already flashed a htc rom and don't particluarly want to change it back, unless i'm certain that I will get the next g service.
With the rom you have provided, do you think it will have the UMTS 850 band on there, and my x1i would be able to connect to it? I would have thought that it would be a hardware preference, not a software. In which case, even if I updated the rom because there is say no "chip" that allows for connecting to that band, it wont connec to it even though I may have selected the 850 UMTS band.
Sorry if that seems all over the place, but yeah... I'm not sure.

No 3G since FRF83

Any solution?
Only GPRS/EDGE does work, if 3G is available, it disconnects automatically until 3G isn't available.
Solution: Set to 2G-Only :-(
Anyone has the same problem?
I didn't have this problem with FRF 72.
Provider: Sunrise Switzerland
Radio: 32.36.00.28U_4.06.00.12_7
Have you tried going into your phone settings from *#*#4636#*#* and setting it to wcdma only? I did that on mine not too long ago and no more dropping to edge for me!

does it lose complete signal? or does it show 3g still but just not doing anything?
Mine was working at first after flash. Then at about 2am it just kept trying to load then times out. Still shows 3g but just dont do anything. Im hoping its just tmobile messing with their towers... I dont see why it would work at first then not now..
The problem is, that i can only have a internet connection, when the phone is logged in into a gsm or edge network.
as soon as wcdma is available, the phone disconnects from the internet.
the signal is always available, but it looses the internet connection when it changes to 3G mode.
when the phone changes from 2G->3G mode, i see for 1s the 3G icon and then no icon will bi there.
when it changes back from 3G->2G, the EDGE/GPRS icon is visible again.

ok thanks for clarification. My problem is different. I think related to phone company.. I still show the 3g signal and even have bars, but the pages dont load and eventually gives me the check your service and try again alert....
So Im hoping soon its working again for me... And I hope you as well figure it out.....
Thank you Good luck!
Had the same issue after update, did *#*#4636#*#* and noticed I was set to GSM only. Set it to WCDMA preferred and now it's good.
Thank you very much, thats the solution!!

Thank you. Updated to FRF83 this morning and I've had a full 3g signal, just couldn't pull data all day. Could over edge. Sure enough, GSM only was selected.
AT&T N1.
I'm having the same issue on a non-rooted phone on T-Mobile. No 3G after the FRF83 update. Full bars of service and 3G displayed in the status bar. Dropping to Edge only works but there is no data with 3G.

Same issue here.
Switching to WCDMA preferred doesn't work for me though.....any help is welcome
I think it's a hardware problem with a lot of N1's.
Mine was ok the first 2 months, and later, 3g not working. This is driving me crazy ):
I have tried everything. Change the simcard, I did a reset of the data with my telcon, and nothing happens.
I've seen these problems on many N1's.
I hope google / htc release a fix for this problem.

how bout checking your bands in the service menu. so *#*#4636#*#* -> phone info -> press the menu key for more options -> select bands -> choose one appropriate for your region (ie "USA BANDS").
If all else fails do a factory reset by going to the settings -> privacy -> restore factory defaults.. of course do a backup/sync/whatever before just to make sure you can get all your apps back.
There's other ways to do a factory reset via the bootloader .. its under recovery and you press up volume or the trackball I think and you can just select all the clear/erase settings there and that should clear out everything on the phone's internal storage.
The factory reset worked for me (via bootloader) when I upped from update-1 to FRF50 and didn't have any data icon next to my signal strength. Could call out but couldn't get data.
Hope that helps.

Check your APN settings. Do a full factory reset from the bootloader. If nothing works you should call tech support again. Most 3g issues where you have issues with connecting are service/signal level related. I *****ed early about my 3g issues on tmobile and it was the network as they've pretty much gone away with improving the backhaul in my area for HSDPA+ or updates to the phone's radio.
HTC is really really really cool about swapping phones and repairing them. If you feel you have a nexus that has hardware issues call them. I did this 3 times already (one time for minor cosmetic issues with the refurb they sent) and I couldn't be happier about how willing they were to replace/repair the phone. It turns out I really didn't have any issues with them at all.. with any issues with hardware from the second refurbished phone. It was service or software related and I'm happy to say with updates/tmobile service improvements I couldn't be happier with this phone.

Thanks blisk, but the thing I don't understand is why Blackberry 9700 with T-Mobile bands, doesn't have problems at all ?
By the way, I rooted my phone , so the thing with the warranty it's complicated
I had it happen last night at work all night, but when i got home i checked my wife's tp2 and it also was doing the same thing so for levity wasn't the phone but tmobile. They started worming the same time also.... I think its tmobile.
Hello, I had the same problem with my imported n1. I'm using the tmobile version non rooted fully stock manually updated to frf83. I did a *#*#4636#*#* and selected wcdma only, rebooted and couldn't connect to my gsm network. Went in again and did a wcdma preferred, rebooted, and I works better, still changes fast to edge and G, but less often, I'm still trying it but I have high hopes its gonna be ok
Mmmm i did have problems with 3G too after pushing FRF83, but i found out that for some reason the APN settings weren't set correctly after the update. In my case the port setting after the proxy of the APN wasn't set, i changed to the correct value and it worked.
In conclusion, check your APN settings.
Just went from FRF72 to FRF83 and it's working fine.
I'm currently set to GSM auto (PRL) in the *#*#4636#*#* and I didn't change it to that after putting on FRF83.

Does 2G work on Telus with Milestone?

I'm currently using CM 6.1.2 on my Milestone.
If I switch to 2G mode in the mobile network settings, I have no connection.
If I use the Toggle 2G app, it doesn't seem to really do anything. If I set 2G to use one of the options that don't disconnect me (WCDMA, CDMA or GSM 2g/3g) it still shows 3G in the status bar so I'm not sure what the point is in using the Toggle 2G app.
Wondering the same thing myself...
Does anyone knows the answer?

I am not certain about this (i use rogers), but i believe that telus has no 2G (edge) network. They built a 3G only network just in time for the olympics to replace their cdma network:
So the toggler probably cant find a valid connection and retries 3G.
Manual mode cant find a network at all.
On rogers, i can fallback to 2g. This is normal according to what i think i know.

thanks for the info.
That's what I thought so have given up on the idea of getting 2g to work
I guess when it comes to 3g and saving battery life, juice defender will have to do as it can turn off data when the screen is off but still have the phone working.
Well, I think I made some progress with this.
On my phone, I was also loosing the connection when switching from 3G to 2G but it's working now. I can get calls, it's only the data aver 2G that doesn't work now.
I have the Cronos rom on my phone, I can tell you what I did if you're interested.
Yes please do.
If it works on cm6 then at least I can also save juice by not using juice defender... oh the irony... lol
edit: hey look at all them Canadian flags, eh?!

Took me a lot of time to find the right switches combination.
Anyway, I have Toggle 2G auto managing the 2G/3G and for the bottom 2 options:
2G network: WCDMA preferred (3G/2G)
3G network: GSM auto (PRL)(2G/3G)
If I check under Setting/About/Phone/Status, I see written mobile network type UMTS.
Hmm... I had those 2 settings reversed when using toggly2g
I will try that.
Right now, my mobile network type shows up as HSPA.
Your post prompted me to find the difference and came up with these 2 useful pages just before my head exploded.

Not sure but I don't think so. You can turn off the data but have the phone connected to the 3G network, right?
I think you could get data over 2G but it's just very slow, right?
With Telus I don't think they allow data over 2G.
zeppelinrox, I wonder why yours shows like this, what do you have active under those settings?
What ROMs are you guys using?

When I'm on 2G it shows as UMTS
With 3G (mobile data enabled) I see it alternating from 3G/UMTS to H/HSPA.
I'm on CM6.
My phone always shows HSPA except if I set it to use 2G then it shows GPRS - which is when I have no data and no phone signal.
I did use the Telus baseband file in AOR though... I wonder how it will behave if I use the Canada baseband....
Also, here's a neat trick....
dial *#*#4636#*#*
A Testing App will show up....
Select Phone Information and then goto the bottom.
You can set your preferred Network type.
Ok so that listbox shows all the different options.
The only options that will save are:
GSM only (2g - I get nothing - shows as GPRS)
WCDMA only (3g - shows as HSPA)
GSM auto (PRL) - (3g - shows as HSPA as well)
All the other options either are not selectable or just revert back to GSM auto (as is the case with WCDMA preferred)
I just did a few speed tests and I seem to get faster speeds with GSM auto than I do with WCDMA only
Gonna try that Canada baseband now....
Edit: Same thing. Except the speed test is slower for both WCDMA and GSM autio so best off using the Telus baseband.
The dial trick doesn't work. I dial the sequence as a phone number, right?
It disappears then nothing changes.
ah.. yeah sometimes it takes 2 or 3 tries...
do you use adw launcher?
If so, you can actually create a shortcut for it... I figured it out today.
1 Press and hold on homescreen and select Custom shortcut
2 Press "Pick your activity"
3 Select the second item on the list ie. Activities (with the ADW icon)
4 Wait for all stuff to load, scroll down to Settings, and press the arrow next to it to see the long list of activites that Settings.apk can do.
5 Scroll down near the end of the list, you will see Testing(.TestingSettings)
6. Select that and press OK on the next window.
I also made one for Battery History, which is actually part of the Testing app but is usually only accessible through Spare Parts.
I still can't get the trick to work... doesn't do anything on my phone
Right now I'm on the 2501 rom (latest 2.2.1 from Motorola) and I can say it's the best I've tested so far!
Outstanding battery life!
I found another way to run Testing App.
With Google gesture search you can set it to launch Settings actions
Let it scan and then write "testing" on the screen
Edit: oh crap I mistyped the code.
Its *#*#4636#*#*
I had 4536 before so I fixed it

Well, after doing some more tests and trying different apps (2G/3G switchers) I can say those apps work only if your cell phone company has both 2G/3G network.
In Montreal, only Rogers has both.
Easy to test (btw: I'm using the FroyoMOD rom): go in "Settings" -> "Wireless & Networks" -> "Mobile Network Settings" and check "Use only 2G networks".
See if your cell phone company is listed when you do a search under "Network Operators". If it's not, don't bother using a 2G/3G switcher.
When doing this, in Montreal I see only Rogers listed. If I uncheck "Use only 2G networks" I see all 3 of them: Bell, Telus and Rogers.
Hope this helps!

[Q] 3g problems nexus one

hello every body
i have this problem with my nexus one when i am connected to 3g service (umts,hsdpa,Etc'). i can't make calls or receive any calls, i can't use the internet (data) or get sms and Etc'. but i have full bars reception. when i check the vi in setting to "use only 2g" the phone work great.
i tried everything downgrade/upgrade roms,radios. i tried to go back to my first backup and even do PASSIMG but nothing help i googled it every where but nothing
please some one can help???
without 3g the smartphone is useless
thanks,
shushkis
What network you on? I would at least see how old the sim card is.
Lots of time if you have an older sim card it just can't handle a newer system.
I am connected through Orange IL
and i tried switching sims even with other networks.
and more the phone worked fine at the beginning it just happened i remember i switch to one of CY roms and it happened
Have you tried a full wipe and reinstall the rom?
yes of course i tried customized roms and stock roms but nothing helped
I would check your apn settings...
apn connected to taking or getting calls?
i thought it's just for internet connection
Its just a guess.
If its a problem on multiple ROMs, its likely to be either hardware or settings. Settings are cheaper and easier to test, and that's the only setting I can think of...?
Of course, doing a full wipe (including system), installing a new ROM, and testing before you restore any apps and settings may be another way to test, but since the apn settings are pre-baked into most ROMs, it wouldn't rule our the apn...?
OK I tried to put apn settings and it didnt help
you say hardware?
but when I check in settings "use only 2g" the transceiver works great .
maybe the nexus have two transceiver one for 2g and one for 3g?
seems un-logical
No there are two radios one for 3g and one for 2g because 2g is for calls and 3g for data but when 3G is unavailable the phone will use the 2g for the data.
The Same Trouble
shushkis,
I have the same trouble, my 3G connection works so bad, but if I use only 2g connection, all works good... I have no idea what happend with my N1. I have a N1 for 3G 850 (AT&T) model.
Thanks for advantage.
So maybe the problem is the hardware? if the N1 have two inidvidul transcivers?
I have also the same problem. I've tried many different roms and radios. I use 900/2100 3G. What's strang is that 3G works perfectly at home, but when moving to another tower I get emergency calls only warning. 2g works fine.
I just started having 3G issues at home. With 3G on the phone reboots like once an hour, but on 2G I've gone days without a reboot. My 3G signal is not the best at home, but I don't know why that would make the phone reboot. I'm on T-Mo USA.

The one I'm using is only a couple months old, and it works well in my Desire HD, and my Moto Defy. It's only the N1, but I guess maybe it could be that. I'll look into more.
If it's only a few months old, then it may nor be the SIM that is the problem. I suggested it because a number of T-Mo users were having similar problems after a recent network upgrade, and a new SIM seems to fix the issue for most...
