I just got a new XDA IIi and when I put my Orange SIM in, it does not connect to the network.
If I use a Vodaphone SIM, it connects & gets excellent signal strength. If I make a call it hangs up by itself after dialing. If I try to call it, it goes to Voicemail.
I will try an O2 SIM on the weekend to see what that does.
I used itsme's xdaunlock tool and that said it unlocked the phone but didn't change the problems described above.
Any ideas anyone?
I tried an 02 simm on the weekend and still not working. I take it into an O2 shop and ask them.

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.
There is big problem with my XDA Exec, when I dial a tel No. it is Dailling and the Call end. The 3G sim card is work well on another mibile, and another GSM sim card is work well on the Exec, but the O2 3G sim card can not work on my Exec, could anyone give me some advice on in, thanks.
If you have a Data only plan then you may not be able to make calls. I think you need to ask O2 to activate voice calls. I have the same problem, but I only use my Exec for web & email as I don't trust it to operate as a phone!

But the problem is that the 3G sim card can be uesd on another mobile for any voice call.
I will try to ring o2 for some solution.
I have ring O2, but they can do nothing and will change another sim card for me.
The 3G sim card can be used on my Moto V3, dial and receive
The normal GSM sim card can be used on Exec, dial and receive
But the 3G sim card can not be used on the Exec, can not dial can not receive, anyone can help me with that.
Thanks in advance
mobile, which tariff/plan do you have? If you have a Data plan and you can use your 3G SIM in another 3G phone (I don't have an unlocked one that I can use) then I may have a faulty SIM as well
jah
My tariff is 200 cross network, everything is ok for last noght.
I have change the sim card with mu V3, now all working. maybe it is the problem with the 3G option
the problem was solved.
I change the network to GSM, then everything is fine. It that means there is some proble with o2 3G netword?? :?:
I just transferred my O2 contract SIM from my Alpine (XDA2i) and the Universal (XDA Exec) is showing "Invalid or missing SIM card".
I don't know what the problem is, it shouldn't matter if the phone is locked or not (I think) as they are both from O2.
What can I do?
The old SIM should work I believe but ask customer service to send you a 3G SIM, which you will want anyway.
It seems to have fixed itself.
I do only have a normal GPRS SIM, not a 3G one - does this mean I can't video call until I get a 3G one?
Thanks.
Well if your SIM is not a 3G one, you won't get UTMS for data nor Video which needs it I believe.
Okay, thanks.
I don't think I'll bother getting a 3G SIM for a while, if the phone will still work with GPRS. I'm in no rush to video call, and another SIM will cost me £10
I have had my m500 for quite a while, I unlocked it as soon as I bought it, as I prefer to use my o2 sim in it. Yesterday I decided to put my Orange sim in it, it would automatically divert my calls to an unknown number, so I had Orang give me a cancel all diverts code (**.....). Now when I go back to put my O2 sim in it, it turns on, but won't search for network signal, instead it says
"invalid or missing sim. you may still make emergency calls if your service provider supports it"
I know it was definately unlocked, just to make sure, I have even unlocked the phone again, but still, other than an Orange sim, nothing works.
Does anyone know how I can fix this problem? Thanks in advance
I purchased a 2nd hand o2 xda exec on ebay, and put my old o2 SIM in it but it constantly says searching. At first I thought this may be because the SIM was an old 2G not 3G sim, so I purchased an o2 3G PAYGO sim and tried again.
CE 1.30.107, Extended 1.30.162, Radio 1.0.9
Still no luck....
I've tried Buzz's Unlocking utility just in case it was locked to a different network, but this being an o2 device I would expect it to be locked to o2 if anything. The unlock utility said it succeeded in unlocking. But still no service.
After a while I get a box appearing with:
Select a network:
O2-UK
@ VF-UK
@ Orange
@ 23420
T-Mobile UK
I've even seen a 'G' icon & and while at work a 'U' icon, so I would guess the radio does work.
I've even checked out the imei to make sure it wasn't blocked on the network (lost/stolen).
I'm a little stuck now what to do, other to use it as a PDA without phone functionality. I might see if i can borrow a Vodafone or Orange SIM to try out.
Anyone seen anything similar, or have any ideas?
Vodafone works
I just tried a vodafone SIM, it worked fine.
I'm having the same problem with an old O2 genie sim it cant find the network any ideas as to why?
If you have seen a G and a U symbol then it HAS actually registered on the network, else you'd have seen an X there. so that rules it out as an IMEI lock out.
Ok as a long shot upgrade your radio to 1.15 and give that a whirl.
