N1 on Three (3) UK?

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

Remind me - I know I've seen that option somewhere - but I can't find it at the moment
Thx

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.

[Q] Phone does not automatically switch mobile network mode

Hello,
My I9000 has a peculiar problem: While both mobile internet and Wi-Fi work fine, switching to 2G when 3G/UMTS/HSDPA coverage is bad does not. It ends up losing network connectivity completely in areas where other phones have no problem staying connected by switching to GPRS/EDGE. (3G coverage is spotty here at times, so this matters quite a lot.)
This problem has first appeared rather spontaneously when it was running its stock 2.1 firmware and has persisted through upgrades to stock 2.3 and CyanogenMod 10 through 11. I've attempted to switch modem firmware to mitigate it to no avail. (Modems XXJVT and ZFJPG/BVJJPG were tried, no difference was noticed - I am rather wary of messing with modems further, as this is my only phone and I'd rather it still could call at the end of the day.)
Moreover, if network mode is switched to GPRS/EDGE manually, it can't be switched back to 3G (either manually or automatically) without a reboot. (The 'set preferred network type' field in *#*#4636#*#* starts resetting itself to 'Unknown' spontaneously at this point.)
Unfortunately, I don't know many details of the incident that caused the appearance of the problem, as I was not the owner of the phone at the time - I only know that it was roaming nationally (within the same country) at the time. (The network type should have been the same, and it's not like it's stuck in roaming in any way.)
Has anybody encountered such a problem before? Is this likely to be a hardware problem, or could there be a software fix?
Thank you in advance for your thoughts.

you need to try fiddling with its network settings (read this for info only) you can use service codes on i9000 to set your network settings . Sometimes it may be due to network settings not set to Auto and set to preferred and at other times it could be antenna connection inside the phone having poor contacts.

Thank you for the hint. I have tried setting the "Select radio band" setting in *#*#4636#*#* > Phone information to European bands manually, and this appears to have mitigated the problem at least partly (phone has switched to 2G and back a few times during the day). I've noticed that it would sometimes just turn mobile data off despite having a good signal, not sure if this is related. It also sometimes seems to prefer another operator's 3G network to its own 2G ("emergency calls only", network mode is UMTS/HSDPA), but this is only guesswork since I have no way to actually confirm that the areas where this occurs have 2G coverage (it just seems really unlikely that they wouldn't). Maybe the fact preferred network type is "WCDMA preferred" factors into this.
TL;DR: Forcing radio bands seems to have helped, other radio weirdnesses remain but aren't nearly as bad.

[Q] Access to more Network Mode options? XT1053

I saw a few screenshots of people's Moto X's from sprint with a bunch of options under Network Mode. I have the XT1053 (TMO unlocked, on ATT network) and the only options I see are "Auto" and "2G."
I browsed around and found that there's an LTE OnOff app, but I'm just wondering if there's a way I can get those options for 3G on my device's Network Mode option list?
The reason why I even care is because for some reason at my workplace, I can't seem to get any data through LTE. My signal will display 3 bars of LTE, but it absolutely does not work. While it will turn off LTE and just say 4G since it's on auto, I find that a majority of my day, it WON'T switch. It stays on 4G LTE 99% of the time and does not function at all. When I walk outside the building, LTE works perfectly fine. Would I be right to assume that the auto mode is literally on borderline between switching, so it never establishes a stable connection?
I guess it brings me to the question, is the Auto mode inefficient / will I have to live with manually turning off LTE every time I get to work? :/

3 bars of LTE is an excellent signal. With 1 bar of signal I can still get 15mbps down from my provider. If your phone is detecting such a strong received signal it won't be switching back to HSPA on its own. For some reason the building you're in may block the phones transmitted signal more then it blocks the signal from the cell site. I am guessing you're on band 4 LTE which has quite the frequency difference between uplink and downlink. Your only option(assuming the phone or cell site isn't defective) is to manually switch to WCDMA with a third party app such as the "LTE setting" app in the Play store. Or unlock your bootloader and flash firmware from another provider that has more options. I know the Rogers Canada firmware has an LTE on/off option, it also has a 2G only option. Sadly Rogers has not yet approved the release of 4.4 (kitkat).

That makes a lot more sense to me now. So basically the "Auto" mode only considers my reception and not transmittance strength, so it never saw a need to switch me off LTE. I am almost sure it is not my phone because I started experiencing a signal loss issue with my S3 a few days ago. I doubt it's the cell site because as soon as I step out of the building, LTE works with no problems.
I did ended up using LTE OnOff to force CDMA and I can actually do stuff now. I went and did a speedtest ...
Ping: 114 ms
Down: 4.06 Mbps
Up: 0.77 Mbps
I guess with the lack of options, I have yet another reason to roll up the sleeves and get my hands dirty. Haven't touched ABD since I had a samsung captivate!
Thank you

[Q] Xperia Z randomly without 3G access (but with 2G access). Hardware or software?

Hi guys!
Around 2 months ago I started having some issues when connected to the 3G network. Most of the times, it didn't transfer at all and my network icon was with the "!" sign.. I was on PAC LP and I blamed it (or some software-related cause). However, if I marked "Use only 2G networks", it did work...
I flashed the phone yesterday. A clean, fresh and quite deep install (wipes, .228 FTF, new kernel, new ROM -eXistenZ-, etc etc). The surprise was that I still have it... If I try to connect to 3G networks I might get a couple of seconds of connection, but then it just disconnects and stays like that until I change back to 2G networks... Just in case I reflashed again, same procedure, and it's still there, even on stock .228...
I bought the phone 2 years ago (in Europe, that's why I can't use LTE here), and never had a problem like this. Of course, I'm at the same place with 3G coverage (other phones do work), I've already tried different APNs, providers, etc, so I hope not, but I'm starting to think this could be related to a hardware issue...
Does anyone have an idea? Is there any software part that is not changed during a flash and could be responsible? Or maybe how to rule out hardware or software issues? This happened while I was on PAC LP, stock .228 and eXistenZ...
Thanks in advance!

It could be many factors involved - one of them could be that the operator you are currently connected (ex. Vodafone, At&t) maybe changed all their antennas in your area from 3g to 4g, and that would result in your lack of connecting to 3g.
I once changed my operator because it had better offer and then I regretted it since the connectivity was worse with the second operator and would constantly switch from 2g to 3g to 4g, all this with a major impact on battery life.
It could be also hardware related, but I wouldn't bet on it. Try checking with another phone with the same sim in the same areas to get an idea what it might be.

Hi aaronkatrini.
Thanks for your answer! However, it's not my operator's fault:
- All other phones in the same area do work.
- Other operators (other SIM cards) in my phone have the same issue, so I guess it's related to my phone, software or hardware...
I haven't checked yet another phone with my SIM card, I could try that to rule completely out the SIM card/operator's fault.
Thanks again!

Can only use phone with "GSM Only" option

Hello,
Suddenly I can only use the phone (make calls and use mobile data) with the option "GSM Only" selected.
If I select any other option I can get no reception (0 bars) and calls/data fail (except for, when selected "WCDMA only", I get reception but can't receive or make phone calls or data neither).
Right now I've tried to downgrade the baseband from V047 but remained the same (already upgraded it again). No success.
I'm running Xiaomi.eu 10.3 stable (last stable release for this phone) and the problem was happening since when I had last weekly ROM from xiaomi.eu. Tried to "upgrade" (clean upgrade) from weekly to last stable to check if it was a ROM problem but remained.
I'm starting to think it's some hardware problem, thinked that it could be the internal antenna released or something but because it works with "GSM Only" I've discarded that option.
Any suggestion?
Thank you very much.

I have same issue + random reboots. I changed SIM slot and reboots are fixed, but GSM is still unstable and LTE to UMTS fallback is slow or sometimes not working, so I set network type to 'WCDMA only' and working whitout issues but my operator using Band 1 (2100Mhz) for 3G and the signal is very poor (~ -113dBm) in house.
I using custom ROMs (latest PE10 now) but with all ROMs I have this issue (with Miui 11 too).

In my case, I have absolutely no reception at nothing else but "GSM Only" and it's not because of the strenght of the network because I have good reception here in all other smartphones (iPhones and Xiaomis).
IDK what else I can try.
