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've got an HTC HD2 Virgin branded from Ebay, It said that it is unlocked. Tried it on T-mobile, O2 and Vodafone.
Only worked on T-Mobile.
When I put O2 or Vodafone sim card, it can't even connect to the network.
Is my device locked??? Or is it faulty? Please help
sounds like its still network locked to me. virgin piggy back on the tmo network I believe, maybe that's why tmo works?
(just thinking out loud)
but the phone didn't ask for unlock code even when i put different sim card?
Hi all
Wondering if anyone can shed any light on this. I've just sold my HTC Tattoo (which is locked to Orange) to a friend. I had been using this phone on o2, it was possible due to an ismart-sim that I had in there. I sold the i-smartsim with the phone so that he could use the phone with his vodafone sim.. but it is not working.
As the phone starts, it asks for his PIN code but then won't register on the network after it has powered up. Without the ismart in there, it rejects the sim card outright - so it is def having some effect.
The only difference we can see is the o2/vodafone sim that I have has only 6 connection points on it, vs the 8 on his sim card. Because the i-smart sits between the sim and the phone it will prevent these extra two points from connecting.
Anyone know why the vodafone sim is different, and if it can be changed for a 6 connection version?
Hi I have been using my htc hd2 for over a year, I unlocked it in the begginning and have been using ATT on it til now. I have recently switched over to tmobiles network but for some reason my htc hd2 won't connect with the tmobile sim card now. I am running an andriod nand.
Does the phone still work with the ATT sim? if so its not the sim card carrier/reader on the phone
Where how did you unlock it?
Just changing to Android does not unlock it, normaly its a cost to you to buy the code £15 to £20 in the UK
So if you only added Android its not unlocked
I'm sure its unlock. As it is branded as a tmobile phone and I purchased an unlock code for it awhile back and I entered it while I was on windows 6.5 and it allowed me to use the ATT sim card til now when I switch back to tmobile it won't let me. My att sim card still works with the phone just not the tmobile
Sound like one the sim:
Does the Tmobile sim, does it work in a different cell?
Does a different sim work in the phone (not including the ATT sim)
I'm pretty sure its not the sim card, I've tried multiple sim cards from friends and the ones from ATT works but for some reason the tmobiles ones don't work I have no clue. Strangest thing too is that I flashed stock windows mobile 6.5 and a new radio rom and the phone connected to the network and i was able to make a call but 2 minutes later "no service" again....
Its only the tmobile sim card too.
Having a problem with a Telstra HD2 model.
With a Telstra SIM in the phone, I can make and receive calls. When I insert a Vodafone SIM into it, I cannot make or receive calls. Call hangs up straight away.
Device is not network locked as HTC phones are not locked with Telstra. Bars display in task bar.
Tried it with Windows 6.5 (factory default) and Android custom ROM. Currently on custom ROM.
Any thoughts?
I had a similiar problem a few years ago and all i had to do was get a new sim card. I was told i had damaged my sim card some how but i was able to save the contacts, transfer them over to the new sim T-mobile gave me and I have not had another problem since.
If you have access to another phone try and insert both sim cards you have in the other phone. If you have problems in the other phone with the sim card thats not working you can safely say its the sim card thats not working correctly and not a phone issue.
Thanks for the reply Craze.
My SIM's do work as I use my Telstra SIM (that works in the HD2) in my old Nokia and my Vodafone on my Galaxy Nexus Prime.
So on the HD2, my Telstra SIM works where I'm able to receive and make calls and my Vodafone is the opposite.
Could it be the phone? I'm hoping that it is so that I can fix it.
Could it be the network providers? If so, then I'll call them which I've already done but they couldn't give me an answer as to why my Voda SIM does that in the HD2.
