Attention USA users of O2 XDA Exec / T-mobile

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

USA T-Mobile G1 to Poland

I want to bring my phone and use it in Poland, it's running newest CyanogenMod and at this point it is clean. From what I was told, 3G may be incompatible so the phone will default to EDGE, which is fine as I don't plan to use overpriced data and stick to wifi. I wonder if there are any G1 users from Poland or Europe using either native devices or imported from states.
Just want to know what I need before I take the phone to Europe. Thanks.

This is what you should do, contact t-mobile and request an unlock code and before you go to Poland write it down then when you are in Poland get a prepaid phone (with a sim card) then put the sim in your phone and enter the unlock code, this case you don't have to spend roaming charges and you might have better reception.

That's the plan, I already unlocked the phone and reflashed it, works fine with AT&T, should work fine with anything else, I hope

I had my T-Mobile G1 imported from the US this spring. Works like a charm here in Germany. So I guess there shouldn't be anything to worry about when taking it to Poland.

There's no 3G incompatibility. It will work as long as you have correct APN settings.
I recommend getting a plus gsm (mixplus) card. From what I could tell (I don't speak Polish, so I had to do some guessing) they have best prepaid mobile internet rates.

There's absolutely no problem with using a US TMobile-branded G1 here in Poland. I was worried about that too when i was about to get one from the US, but after some research it turned out that there shouldn't be any problems. And there weren't any. Personally tested it with orange, play and mbank mobile (virtual operator using plusGSM infrastructure).
3G (i wszystko) inne działa jak należy, więc bez obaw
[translation]3G (and everything else) works nicely so no worries[/translation]

Cannot Roam on an unlocked phone?

Visiting Germany, with my unlocked Galaxy S which I use in the USA with AT&T.
While all my co-workers are able to get service on Voda or O2 I get an error saying my SIM is unable to register on "any" of the networks (I forget the other 3).
Did AT&T screw with my SIM - I just got a new one before I left the US because my old one was giving some errors - This is an unlocked SGS, I did not think this would be a problem when traveling.

Unlocked doesn't mean it automatically works. You need to call ATT to have call them to allow you to use it in other countries. It will be expensive. Recommend you goto a store and buy a pay as you go sim card and pop it in... that is what unlocked means.

Thanks for the advise. It seems that while I have roamed on AT&T while in Jamaica
(when I had my sim card in old iPhone) Jamaica is a US region dialing format (meaning 1-876-000-0000) while Germany and the UK is not (+49xxxxx).
You therefore have to "request" the "Standard" international dialing feature (as opposed to the enhanced $5/month version).
So my phone is working now.
I will get a SIM tomorrow from O2 or Voda, but here in Wurzburg all merchant stores are closed on Sunday.
Question, Why won't my phone set the date and time while I am here in Germany (I have told it to do so but the time is still US eastern) do I have to update the timezone (should I even have to do that since I told it to automatically update time)?

Wrong Carrier Name

Hi,
I'm using HTC 7 Trophy in Slovakia. I tried Orange and T-Mobile SIM and both works fine, but I get wrong carrier name:
Orange is shown as T-Mobile CZ,
T-Mobile is shown as Eurotel - CZ,
as long as I search networks I see O2 as "23106"
Is there any way to fix this? The phone was bought in Austria A1 Shop.
Thanks for answers.

same here in germany. my carrier said that microsoft currently did not open the way for carriers to send konfiguration data through sms/mms to change settings.
thats way windows phone 7 devices chooses the carrier its "having" in their list ...

hmmm, hope that this "bug" has nothing to do with roaming charges, interconnection payments etc.

It's just the name of the mobile network. There is a tiny database on your phone('s radio ROM, I presume) looking up the correct name for your network based on the network ID(23106). Flashing your phone to (a more) recent version should resolve this (in the future) since it updates this database on your phone.
Check out http://numberportabilitylookup.com/networks to retreive a (complete) list of networks.

I have locale to Czech (on HTC 7 Trophy) and carrier is "Vodafone CZyyyy", where is the problem and why? Fix it an update? In English locale is OK, "Vodafone CZ"...

same problem here. Vodafone CZyyyy. #facepalm

...in Japan.

I wonder, does anyone know if I'm able to use an unlocked HD2 (International (if that's accurate)) in Japan, if I pop a Softbank/Au simcard in?
私のオープンHD2(国際的)に日本以てSoftbank/auは大丈夫でか? ごめんなさい日本語よこ話せません。

You can use softbank sim and NTT DOCOMO sim.
Softbank or NTT Docomo is better.
AU is not recommended.

Cheers, I'll possibly not be able to use Softbank, the missus swears by Au and DoCoMo are rather expensive, I was just wondering about the bands on the HD2, if it's a Quad-band.

Yes, HD2 supports Softbank's networks in Japan, at least I was able to connect it while roaming in Japan.
Don't take my words for granted but afaik, softbank phones are sim-locked to softbank sims only while softbank sims can work on softbank and non-softbank phones.
However, you as a softbank subscriber may have problems sending out and receiving email/MMS and may also be charged for data usage instead if you were to use a non-softbank phone unless you know the settings/get a custom softbank firmware
This thread below, tho old, may be helpful for you as it offers a software workaround.

Thanks for your advice. My crappy-iPhone was locked to Softbank, I can use any sim-card, but whenever I upgrade, I need to put the old sim-card in.
I guess I'll just take it with me, if it doesn't work, I'll order one that does.
Thanks for your time guys
