ok i got my phone on o2 after loosing it i reported it lost they blocked my ime number and sent me a new sim card, then i had the phone returned to me and o2 said ime number had been unblocked. when i inserted new sim i got no signal on o2 sim card so i tried someone elses o2 card same problem no signal but it works in other phone. also if i put other network sim cards in xda2 they work do any of you out there know why my o2 cards will not work in xda2?
Are you SURE O2 un-blocked the correct IMEI?
Sounds to me like the IMEI is still blocked - No O2 SIMs work in this phone but do work in other phones; other carrier SIMs work in this phone.
Really sounds blocked.
I have a UK purchased O2 XDA exec, but now live in the USA. The O2 XDA exec is supposedly unlocked for any sim cards (I have been using a Virgin sim in the UK fine) .
I purchased a PAYG USA T-mobile sim that won't work, anyone got it working, or if I need a different kind of sim?
As soon as you put in the sim, it comes up with incorrect sim message.....
Is it possible that O2 could have it unlocked to European or UK but Locked to USA sim? Strangely there does not seem to be any way of putting in an unlock code in any case.... it just gives the incorrect sim message..............
Hopefully it will work with another sim???!!!
Any help greatlt appreciated!
I have a qtek 9000, which was never locked. I live in Poland, and tried 3 sim cards from plus gsm. They all gave the same message you are getting. The only card that worked successfully was the plus gsm 3g sim card. Also, cards from another company worked. There seems to be some difference in 'new' and 'old' sim cards, and the universal is very tempermental if you don't have the right one.

I have an O2 XDA EXEC from the UK which I purchase from a friend and have him sent to me here in the US. I am using Cingular without any problems.
Remeber guys, Not all operators in the US use the same frequencies/sim types as their European Counterparts.
If the sim is trying to operate on a frequecny that the universal is not able to use, then it might cause this problem.
superseagulls:
As far as I know - a device which is SIM UNlocked cannot be locked to specific SIMs.
It is far more likely that the cellular operator that you have purchased your new SIM in the USA from is using different frequencies than are supported by or in some cases selected within your device;
OR (possibly) the operator puts some usage limitations/locks within the SIM - ask your new operator about using GSM devices which are not purchased from them and which frequencies are used.
I suggest you initially ask them anonymously in case they DO have problems with devices other than their own
jasjar on T-mobile
I am using a jasjar on T-Mobile in the USA. I got 3 phones on a family plan, took the SIM out of one to put in jasjar, and it has worked with no problems. I told the sales lady I would be putting the SIM into a 3rd party device, and she didn't see any problem with that. It was a Motorola phone, but I don't have the model number offhand.
Cheers.

Your PAYG sim might be looking for special settings on the T-Mobile phone. When I workjed at T-Mobile UK we tied the Java extras on the SIM to the handset, so if you used a non t-mobile handset you didn't get the extra features.
You probably have an old 8k or 16k SIM,
Is it more than a year old,
The XDA Exec etc all require the latest 32k SIMs to work,
You should have no problem with T-Mobile USA just explain you need an updated SIM for a new phone
I have the same problem with Optus, Australia. Anyone know what frequency they run on?
Frequencies:
USA/Canada GSM 800, GSM 1900. UMTS 1900. UMTS 800
Europe, Asia, Middle East, Africa, Oceania: GSM 900, GSM 1800, UMTS 2100
South America: A mix of the above
The only SIMs which look for specific firmware in the US are TracFone and Net10. The SIM probably needs to be replaced. This is aproblem in other newer phones too
I just got my new M5000 yesterday, bought off Ebay.
It was sold as unlocked - but the phone refuses to accept my sim card for some reason - tells me invalid or missing sim. And yes, my sim works fine on another telefone. I have tried another sim from a friend in my M5000, and that works fine. Does anybody know if the M5000 has some limitation as to what sim cards it accepts?
Thanks, Paul
Universal & Sim
If you have Sim card very old - I always happens - change it for free at your operator for 3G ( UMTS) services.
Need help guys...
this might be a silly question but i've searched through google and this forum for the past few days and still haven't found the exact answer to this issue.
well, the issue is this:
1) Bought a 2nd hand Touch/Elf from a local reseller and when inserting a Celcom (mobile provider) postpaid simcard (128K) it does not recognize the sim card and show the message "invalid SIM".
2) Inserted DiGi (another provider) simcard (64K prepaid) and it works brilliant. and I am currently using it with my Elf right now.
3) Tried my friend's Maxis (another provider) simcard (128K postpaid) and the problem goes again.
4) Tried another friend's Celcom (64K prepaid) and the same issue went on again.
Does it have something to do with SIM unlocking because i suspect that this Elf is not sim locked.
does it have to do with the capacity of simcards (64k/128k)?
please help as i would like to use my Celcom postpaid with this device as it is my primary number and i wouldn't like to carry 2 phones with me around.
my HTC P3600 was purchased in the UK and was locked on the Orange network. I got it unlocked before moving to Canada to study. I purchased a sim card from one of the GSM mobile operators (Fido). But when I insert the sim card into my phone it shows me as roaming and the network also charges me roaming service rates even though I am not in a roaming area.
I upgraded the ROM from WM5 to WM6.1 and still the the problem is not fixed.
I also used the sim and CID unlocker (http://pof.eslack.org/trinity-unlocker/) to "reunlock" it but that also didn't work.
Can anyone help me out here. I love my phone and would like to use it instead of getting another one.
So please whatever suggestions you have would be welcomed.
thanks in advance
