Unable to get a data connection - Desire General

Hi,
I'm in Ireland, on O2.
They've given me different settings to try out, and I've gotten advice from others with the same SIM-free Desire on O2 Ireland who have been successful. I have never gotten a "3G" or "H" symbol for connection. I'm only able to connect for data through WiFi.
Using the same SIM in my Sony Ericsson results in an HSPA connection, so no problems directly with the SIM.
After all the trying for a couple of days, I wonder in the end if it's possible that my handset has a 3G aerial hardware error. Is there a way to perhaps test for this?
In the phone app, pressing *#*#4636#*#* brings you to an information screen which might help. For GPRS it just says "disconnected".
Thanks for any pointers.

help to unlock XDA Exec

Following Buzz's installation instuctions I am stuck with these two items.
9. Activate Radio even without Sim in it saying something about no Sim)
15. Flash your original Radio ROM. Do not upgrade the bootloader until you restored an original radio rom.
I think I am just about there with number 15 (with the resource on this site) but can not find anything on #9.
I know a lot of people say that it is already unlocked, but it seems unlocked to a few networks.
Regards
hi, XDA Execs should be unlocked
Does it ask you to enter the unlock code if u enter another sim?
If it doesn't then it's unlocked as far as i know.
What makes you believe that it's locked to a few netwroks, maybe it's because you're trying to find a non-existent umts signal...
Turning the radio on means turning flight mode off (and for the purposes of unlocking you do that without a sim)
Hope that helps.
I take it the UMTS is another name for 3G. My BT account is a normal non 3G account. Is it a case that I need to alter some of the settings, the networks it lists are...
@VF-UK
@ O2-UK
@ Orange
Is ther anything I should try....
umm, what happens if you insert a non-o2 sim into your phone?
If it's continually searching for a signal, it might be trying to search for a dodgy 3G/UMTS signal
in which case try going to phone settings, then in the band tab , select GSM instead of auto or wcdma
In the worse case scenario, if/when you flashed the radio 0.00.00, you might have had some problem with your USB (See the unlocking thread)
Thanks for all your help.
I think I have now got to the bottom of this. The fact is that BT use the VF network. The phone logs onto this, so I guess this is normal. However the signal strength never gets above 2 bars, is this normal?

Not anymore, dude. BT sold BT Cellnet (now O2 plc) a little while ago, but now they have started their own mobile service again (called BT Mobile) BUT piggybacking Vodafone's network.

O2 roaming GPRS not working

Hi,
I got my O2 Orbit a day before leaving the UK for Qatar so didn't get a chance to suss this out before I left.
I'm still running on my O2 sim etc. When I arrived the GPRS doesn't register and the GPRS/internet connections etc all keep asking for a modem setup.
Qtel is the operator here but talking to them about roaming internet/gprs connectivity with an xda is fruitless.
I can't get much help out of O2 either....There's got to be a way, there has to be a way.....
Can anybody help at all? Please?
try this
After two or three trips away with o2 device and lots of calls back to the uk my solution was to go through all available networks one at a time and force the device to try data connections I still need to do this five years on even after telling o2 how to connect

02 UK 3G - How ??

Just setting my phone up after moving from a Nokia N95 8GB
I'm on 02 Pay as You Go Text & Web
£10.00 per month
300 Texts & Unlimited Web
Using the setting as supplied (02 bought phone) I get a 'H' in the status bar, but no 3G and no data throughput at all.
It does appear to be trying I get the up/down arrows but nothing else...
I can't view any web pages or access anything...
The nokia worked fine at 3G.
Any Ideas ?
Thanks
go to settings, choose wireless and networks.
after that choose mobile networks (not mobile network).
choose Access Point Names then choose O2 MOBILE WEB.
change APN into payandgo.o2.co.uk
DONE
Thanks for the reply.. but that hasn't worked.. I keep getting connection failed.
My Settings are:
Name: 02 Mobile Web
APN: payandgo.o2.co.uk
Proxy: Not Set
Port: Not Set
Username: mobileweb
Password: password
MCC: 234
MNC: 10
Nothing else is set. !!
The username needs to be "payandgo" for pay and go
On my Nokia it was mobileweb !!
I'll try that and post back !
The generic setting on the phone connect me with GRPS, but not 3G.
Just had a web chat with 02 - God help Me !
My sim works fine in my N95 8GB I get a solid 3G signal anywhere in my house.
In the Desire I only get 'H'.. no '3G'.
O2 have said their network my not support PAYG 3G on the Desire
Any suggestions what I can try ! ?
lol having your handset display a H rather than 3G is better trust me
I'm with O2, on 3G you only get 384KBit/s on H(HSUPA) you will receive 3-4MBit/s
The icons on O2 will change from H->3G->E->G depending on your signal.
Thank.. But U get no data throughput at all.
Making it useless.
How do I get internet access on this ? Without using Wireless !
Set up a new APN with:
Name: [whatever you like...]
APN: payandgo.o2.co.uk
and don't fill in the rest.
Also make sure Settings>Wireless & networks>Mobile networks>Network mode is set to GSM/WCDMA auto or WCDMA only. If that still doesn't work I'd be leaning towards a local network issue, etc.

You refer to 2 "problems" but in reality you only have 1 and that is that you are not getting any data through!
H is faster than 3G as someone else mentioned. It is 3.5G so if you get that you should be happy!
Your data issue is an APN issue. I have had a similar problem with MMS. It was only after 7 calls to O2 and speaking with a number of phone monkeys that I managed to get it working.
I would suggest you persist!!
I've reset the phone.
and I'm back to square one !
G connects and works slowly. H connects but no data.
Any ideas ? before I give up and send it back !
dialling *#*#INFO#*#* Shows the phone has conencted, but it fails a ping test.
(on a strange not this also shows a mobile number that isn't mine !)
Thanks
I have/had some O2 PAYT sim cards which say '2G' on the packaging. These, as I recall, would not connect to the 3G network at all, or at least they would, then seconds later they'd drop back off the 2G, regardless of the phone, so once 3G coverage became widespread I'd have to lock the phone to 2G to get it to work properly.
That said, I've been on contract for a long time now, and the only PAYG sims I ever use are Orange ones (Orange Wednesdays ) so I've no idea if any of their SIMs will still do that, or if indeed that is your problem, but I thought I'd chuck it in as food for thought. Have you tried an O2 PAYG sim that originally came with a 3G phone?
update...
called in at my local O2 shop and they gave me a new sim card advising it would take 24/48 hours for my account to be moved to the new card.
1 hour later my new sim is working. Sat on the prom accessing web via 3G
Came home, connects to 3G no throughput
Just been out for a drive, 3G works 5 - 10 minutes away from my house, but not at home or in between !
I Will try a few other areas, may be my 'cell' is having issues.
When I had a working connection I checked the 'testing' menu and noted the LAC & CID, they are different from the one at home.
(not sure if this means anything as I don't know the area a cell covers)
Is there anyway to find out what cells are in my area ?
When it fails the testing menu shows:
Ping ipAddr: Fail: IP addr not reachable
Ping Hostname(www.google.com):Fail: Host unreachable
HTTP Client test: Fail: IOException
Anyone know what the IOException is about ?
Thanks
hmm, maybe your sim is not compatible with hsdpa, I think some sims can only go as fast as 3g
should have said, connected at H at on the prom !
Not to sure what's going on, but this is a new sim.
The cell tower in your area is probably having problems. Give it 24 hours and if the problem persists, call O2 again.
Yea even I have that issue on T-Mobile and O2, the cell tower can have problems and 3G will have no data throughput what-so-ever but 2G will.
O2 servers Down
I am was having a similar problem my o2 internet connection it was going off for hours then coming back on, it was fine before i had no problem.
So I gave o2 a call and they said that they were having problems with there server and it was temporarily down and should be fixed soon, I am on o2 sim only plan hope this helps.
Also do a o2 coverage check :

Thanks
I'll see how things go over the next couple of days !

DINC2 unlocked but doesn't recognize SIM in Panama...help!!!

hi. i just got this phone in the states before coming down to panama. it is verizon, but i called them and they gave me the code and now the phone is unlocked....but i can't get coverage here in panama. i've tried sim cards from a few of the local operators and none of them seem to work. i sure hope someone can help....here's what i've done so far: (oh, pls b patient, i'm a bit of a technophobe)
-unlocked sim. phone gives me sim lock is disabled message....that means i'm good to go, right/
-set phone to gsm only mode.
-software is androaid version 2.3.4
verizon global services told me that everything was as it should be and that the phone should work w/ a local sim card so i'm not really sure where to turn to......hopefully someone here can help. verizon also told me that the phone should work on the frequencies here. i have a claro sim card, but have also tried movistar, digicel, and masmovil. i was told that they use either 850 or 1900.
so, i'm totally stumped. hopefully i'm missing something stupid....btw, tried the sim in other phones (from europe and panama) and it worked w/ them. don't think it's a hadrware problem, but am i missing something? is there a setting change? do i need some kind of software update?
thanks!
update- get cell phone reception w/ gps on
don't know if this will help anyone get to the bottom of this issue, but i realized that when i have the gps on, i get full bar coverage. unfortunately, i can't leave the app on in the background. this makes me think it could be a hardware issue....bad antenna? anyone have any ideas
Same problem
I have the same issue as OP. Got my phone sim unlocked, and it runs on SenseMOD-2012-05-18-225643 Android 4.0.4.
For once I did a factory reset, skipped verizon activation (can´t do and won´t work because I´m not in the USA and do not have a verizon SIM or service), set my network preference to GSM/WCDMA, and the network wasn´t working.
Rebooted, my network is identified as soon as it starts, but then it goes to "No Service". Try to search for network but my carrier does not appear.
Any help?
EDIT:
Playing around with the phone, setting GSM as your network and restarting the phone let me make phone calls. No internet though and the APN was configured correctly. The "E" symbol for the internet blinked once in a while, but never got service.
Also, playing around some more, got my phone to not recognize the network again by removing the SIM another time. This sucks.

[Q] why can I not text when on 4g

Hi All, can I start by saying I am not overly techie but would appreciate any help you can give.
I have a HTC M9 on Vodafone, I have not changed anything technically from out of the box.
My problem is that when I am on 4G I can not send or receive texts, if I change settings to 3G then it all works. This is the same if wi-fi is on or off. I only have two bars on 4G but this is not a problem for my wife's I phone also with Vodafone. Any suggestions / thoughts on why this would be the case?
I should mention I have changed the SIM card and wiped and re started the phone (on advice from Vodafone). Thanks Ian G
Sounds like an APN issue

Thanks for the response, is there anything I can do about that?
Is it limited to a certain area, not seen this issue and I am also on Vodafone, A manual roam may help, go to Settings>Mobile Data> Network Operators>search networks, then choose any other network except Voda and when it fails to connect select Voda and then retest, this should update your location on the HLR and may resolve your issue.
