Unlocked XDA with O2 SIM

:?:
I have an unlocked XDA working with an Orange SIM, I have been given an O2 SIM by my company and want to use it with my XDA, but when I put the O2 SIM in my XDA it will not receive any signal. I tried a T-Mobile SIM and this seems to work ok, but the O2 SIM will not connect to the network. Is this to do with the fact that I have unlocked the XDA?
When I unlocked the XDA I ude the XDAunlock utility and do not have a copy of the lock code. Does any body have ant ideas please?

Are You sure, that the O2 Sim is working? Have you tried it in an other phone?
How old is this SIMcard? I know that there were som eproblems with a view SIMcards.
It's no problem of the unlocking.

Both T-Mobile and Orange in the UK use the 1800 band, the O2 sim uses the 900 band, I would be interested to know if a Vodafone sim will work, can you get hold of one and try it?

My guess is if you have brought the phone 2nd hand it is barred on O2, due to the fact that cross network barring did not start till about the middle of last year if the phone was reported lost/stolen etc etc before then it will still work on the other networks, also make sure you have the setting so it can pick up signal on the 900mhz (O2 Vodafone) or it will never work.

:? Hi, Cruisin thru,lonegunman and lumpistefan
Thanks for your replys, the O2 SIM has been tried in an XDAII and works ok. The phone is not lost or stolen I have bought from the guy with the XDAII and I was with him when he bought the XDA I.
As far as I know the GSM is set to 900/1800 (its a model 10A), does it need to be set to just 900 for it to work with O2?
The SIM card is approx 1 year old and works ok in an XDA II.
Unfortunately I do not know anybody with a Vodaphone SIM.
I will try changing the band to 900 and see if this works, I assume this is done via the bootloader method (holding power button while pressing reset).
Many thanks , any other ideas would be appreciated.
Frootmig.

Have a seach round on here I think you will find that it is a sim card fault and you need a new one.

blocked phone

i have recently bought an xda exec that is blocked to uk networks.
will a three network sim work in it?,has anyone tried?

If it's blocked to UK networks, it's ALL UK networks sorry...

When you say "blocked" do you mean that it is IMEI blacklisted or that there is a network lock on the phone that stops you using UK SIMs?
If it is IMEI blocked you're stuck. I haven't read of an IMEI change solution for the Universal yet, but that is illegal anyway (prison sentence illegal, not just a smack on the wrist).
If your phone is SIMlocked you can use the unlocking tool on Buzz's site to disable all locks.

the phone is unlocked,but says no sevice,if i put in a virgin sim it has a signal but you cant make calls.

Thats good then,, its unlocked but Virgin doesnt have settings for the Universal yet so your a little stuck other then that try flashing it with Tmobiles ROM that may help as Virgin is a sub group of Tmobile

please don't post answers like this when you don't know what you're saying to be 100% true.
a) ROMs don't affect gsm service - it's all contained in the SIM (that's what SIMs are specifically for). every rom of a particular version of wm has the same phone program - just different skins.
b) gsm communication is standard across all handsets - there are no "settings for universal" other than for MMS and a few other things (which are not the subject here)
c) virgin rent bandwidth from a number of companies including t-mobile (i.e. they are a virtual provider)

HELP????? i cant seem to get my phone working on gsm?

Dear friends
i have a unlocked HTC 8525 !! i am in brazil and can't get the sim card here working with my phone. i can see the sim menu and everything but the phone only says no service . i try'd to change the network under phone/menu/option
but i couldn't get it working , and the closest suppor for HTC is in Sao Paulo and im 600 miles away
Help me please

Hi DJFuscao,
I have an HTC Tytn that I regularly use in Brazil (Sao Paulo) since oct 2006.
I´m not sure if I will be really able to help you, but I´ll try to give you at least some information about my experience.
I believe that sometimes autodetect network does not work properly. You may try to change these settings:
- Settings-->(Personal Tab)-->Phone-->(Band tab)--> Select your Network type: change this to GSM
- Settings-->(Personal Tab)-->Phone-->(Band tab)--> Select your GSM/UMTS band: GSM(900+1800)+UMTS(2100)
I have also experienced some problems some months ago when VIVO activated their GSM network. It simply stopped working, kept searching but did not find TIM´s network.
What I have done then:
- I have changed from Automatic Network Selection to Manual (you will find this option on "Settings-->(Personal Tab)-->Phone-->(Network tab)--> Network Selection".
- then I tried to click on Find Network on the same screen
- I chose TIM from the list
It has not worked at the first atempt because there were some different options for TIM on the list but it has eventually worked.
Another thing I would check is if it works with any other GSM carrier from Brazil. If you can borrow a SIM from some friend this could also give you some clue.
You may also find some specific information about HTC 8525 phones in Brazil on the link below:

[Q] G2 on O2 UK

Hi
I would be very grateful for some help.
I have just received an unlocked US G2 (not a UK desire Z).
I live in the UK and was previously using an iphone 4 on contract with O2. When I insert my sim card and turn on the phone I get no network service.
I was under the impression that the american version should work in the UK. Does anyone have any suggestions?
Thanks
Nick

Are you sure it's unlocked? I use an American G2 on T-Mobile UK and it works perfectly. But I unlocked it myself after importing it.

Check to see if its been set to 3G / HSDPA only... O2's 3G network isn't the most expansive..
Its in settings / wireless / mobile network / network mode..
It should show "GSM / WCDMA auto"
Craig

I reckon try the gfree root, s-off, super cid from the Development forum.

Thank you for the quick replies
The phone was advertised as unlocked however this may not be the case. On the G1 when I inserted the same sim into a locked unit a message appeared on screen informing me that the phone was locked. This did not happen with the G2 - it simply has no network service.
Is there a simple way for me to check the locked/ unlocked status?
Nick

Weren't there issues with unlock codes? Me thinks so.... I'll have a search.

.... So use Gfree Root & Super CID!?!

This worked - phone was obviously not unlocked

[Q] Displaying wrong carrier name

Hi all,
I am a proud owner of a Omnia 7 (with Mango update). Everything works fine, except that my phone is always roaming. My network home network should be "NL TELFORT" but it displays "NL KPN". I am aware of the fact that Telfort does not have it's own network anymore and that it's using the KPN network, but when I tested my SIM card with a HTC Titan, it displayed "NL TELFORT" and was not roaming. An other SIM card of Telfort also displays KPN on my phone. Last week I had my phone displaying "NL Telfort" for half a day, when travelling thru the country.
The same problem occurred on my Android device. In Android 2.3 the feature National Roaming was added and that resolved my problem.
For your information, the Telfort sim has it's own network code that is different from the KPN network code. It's also not possible to get a different SIM with a different network code, because Telfort is not supplying them.
Things that I have tried:
- Selecting the Network manually; The network is not in the list. Only NL KPN.
- Using the Samsung app: Network Profile; Selected the right profile.
- Searching the internet for a week, with no results :-(
Hope someone can help me!
Kind regards,
Mark
Samsung Omnia 7
OS Version 7.10.7720.68
Firmware revision number 2424.11.8.5
Hardware revision number 3.15.0.4
Radio software version 2424.11.7.2
Radio hardware version 0.0.0.800
Bootloader version 5.8.1.9
Chip SOC version: 0.36.2.0

Try this..
Dial ##634# on the dial pad
and it will enter the diagnosis app.
and then inside the app, dial this *#94765# and it should reset.

Hi Hboos,
Thank you for your reply.
I've tried this and my phone rebooted, but still it says it's roaming.
For the record, after that I have set my phone to factory defaults. But still no result.
Is it possible that my radio version (or something) doesn't know the network code of my carrier? And that's why it's displaying it's own name?
If yes, is it possible to add the network code to the list on my phone?
Kind regards,
Mark

I did some more research on the internet.
My PDA version is I8700XXKH5. This indicates that the firmware is for the following regions: Austria, Benelux, France, Germany, Hungary, Italy, Spain, UK.
My Phone version is I8700XXKG2. This one applies to the same region.
My CSC is: I8700XENJK1. The XEN part idicates that the CSC is for the Netherlands.
So far everything is looking just fine. Except for the part that my phone is not displaying the right carrier name and that it is always roaming. Can someone clarify to me in which part the list with carriers is included? First I thought it was the CSC file. But that file only consists of the MMS/3G settings.

Hey,
If you reset your phone to the factory settings, then you would have lost the settings you applied with the Diagnosis app..
Sorry can't help you much beyond that.. don't know about the registry or the different files.
Try the diagnosis thing again but don't reset the device to factory settings.
Good luck and hope you get this sorted

Maybe something silly, but did you check if your data roaming option is stated as: don't roam?
Settings -> Mobile Network
Maybe it's worth checking out the Network selection option right there.
Another thing, what's the deal with this roaming? You say Telfort is using KPN's network.. so I don't quite understand what the deal is when your phone displays KPN as a carrier. Sorry for that.

@Hboos, thank you.
@mb706:
Telfort used to have it's own netwerk (with also it's own network code, to be exactly 20412). In 2005 Telfort was taken over by KPN (networkcode 20408) and slowly the Telfort network was shutdown. Now they still use their own network code and that's why they are roaming on the network of KPN.
Hi and MTV mobile etc are MNVO's and use the network code of KPN, with only a different display/carrier name.
