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
Hi All,
I was wondering if I could use my unlocked 8525 with Verizon's net work if I switched to them? I'm not sure about compatability of the phone with Verizon's voice and data services and was wondering if anyone knew.
Thanks
I dont think so. Att and verizon use two different technologies. Att uses GSM and Verizon uses CDMA. Im almost certain tho a phone that is based on GSM cannot be used on a CDMA network. The phone will work on TMobile or USCellular. They use a GSM based technology. Verizon Sprint and Nextel all use CDMA. If i am wrong and you can use the GSM based phone with Verizon CDMA then someone please correct me. But i am pretty certain you cannot.
OK,thanks. Thats what I thought
Verizon does not have sim cards, is that correct?

Not that I've ever seen.
I know sprint phones have sim card slots, but they are not used, at least in the USA.
My guess is that CDMA phones can be used in the same way as GSM phones as far as switching sims to use different carriers, but the CDMA carriers in the 'states don't use that functionality (probably to keep a tighter grip on their sucke....customers and wring more money from them through phone sales/upgrades and extra services, like a data service to put on extra ring tones )
I know that I don't know much about these phones, but what of the setting inside of Settings/Personal/Phone/Band where you can select WCDMA as your network type? I've got an 8525 and it shows as an option, but I just don't know if anyone's tried it before.
CDMA and GSM phones are totally different. The only SIM based verizon phone that Ive seen its the Blackberry 8300 its world edition soo it can bu used through a cdma and also a GSM carrier. I would be interested if anyone knows how to say make a sprint phone capable of being on verizons network. That would be something different.
actually a sprint phone is capable of being used on verison network any cdma phone is. in short the way cdma works the subscriber info is assigned to the phone's esn by the carrier so only the carrier can change your phone with gsm the sim (Subscriber Identity Module) holds the subscriber info and it is assigned to a sim card id not a esn (electronic serial number) so all you have to do to get a sprint phone to work for verizon is get verizon to let it (GOOD LUCK WITH THAT) you would have better luck the other way around verizon is the pickiest co out there when it comes to network integrity and security issues they seem to think that letting people use any phone they want could somehow hurt their network

WCDMA is 3G. 3G on GSM systems is essentially a CDMA standard, but not the same CDMA as Verizon uses. It is not compatible.

please, anyone can tell me can I use my phone in Korea? actually I've just moved to Korea, and as I checked with my country SIM card and my friend SIM card (from Bulgaria) , the phone worked as roaming and i could make a call, so I think that it's possible to use my phone with the service here, but when I borowed a SK telecom SIM card from my friend's phone and put it into my phone, the phone didnt work, so please tell me do I have to unlock, install or register anything to use the service here (my phone's already unlocked SIM)?

Hello
From what I know is, Korea use CDMA signal instead of WCDMA (European 3G signal) there for I'm afraid that you will need to get a phone in korea.

I want to get a Magic, but I am on Telus, in Canada.
I know that when I was on their CDMA network with my Touch Diamond, I had to be careful which ROMS I falshed, and that they were compatible with my network and such.
Is it the same case for the Magic and a HSPA network that actually uses a SIM card?
I am new to htc world. I bought a Touch2 6 months back in Netherlands and it was on Telfort (a local network provider) on Dutch language. Then I moved to Canada and changed the ROM with the help of hardspl to English. But I can not use my new Bell Canada SIM card in this phone. It does not catch any signal. But when I checked through settings - connections - connection setup, then I see under country Canada there are a list of service provider's name listed but no Bell there. I guess this does not mean SIM lock or so. How can I add Bell in that list and make my bell sim work in my touch2 ?
Thanks in advance for any kind of clue !

It won't work at all no matter what you try... the phone doesn't have UMTS 850/1900, and Bell doesn't have GSM. Sorry!
It'll work on Rogers & Fido in 2G/EDGE mode, that's all you'll get in Canada.
what the mate means is that bell uses CDMA and the Touch2 is a GSM mobile phone so you can't use it with bell.

No, that isn't what I mean. Bell's HSPA network, launched about 8 months ago (the one which uses SIM cards) is UMTS-only. The Touch2 does not support Bell's UMTS frequencies. Therefore it sees nothing when a Bell SIM is inserted.
