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 know some older phones won't function without a qualified SIM placed into the phone. Do I need a SIM card to unlock the 8125? I only have a T-mobile SIM and no Cingular SIM.
i have HTC Touch Sprint I need program to unlock sim to cdma
I am pretty sure CDMA carriers do not use SIM cards. So I do not understand what you want to do with a SIM card.
You cannot use a SIM card with the Sprint Touch.
Hi, ive just got an hd2 locked to t-mobile UK and when i put the sim in it dosent pick up and signal, also i have tried it in my htc elf and that dosent pick any think up! please help.
Now am I getting this right?
The sim is not working in 2 different phones, correct?
If so - then are the sims compatable? (unlocked phones or the same sim as brand, ie orange phones and orange sim)
If so replace the sim if not - then think about it a bit
Hi,
I'm about to buy a locked and used Note 3 and I'm planning to unlock it with a Sim unlock code from a website. The thing is, I don't know which models can be unlock through this method. Is there any limitation? For example, can I unlock a Sprint device to use on GSM carriers? Or T-Mobile/AT&T only?
Also, for carrier locked phones, do I need to activate it beforehand with the specific carrier Sim card? For example, do I need a T-Mobile Sim card, activate the T-mobile phone and then, use my unlock Sim code with my own Sim card? Or can I just skip the activation process and ?
Thank you so much for your time!
