Hi, I SIM unlocked my trinity. I now can insert a SIM Card of any carrier and use it as a phone But when I try to connect to GPRS/UMTS it tells me imediatly (~ 500ms) that the connection was terminated by the other side. With the stock WM5 ROM (Vodafone Germany) it say its not allowed the connect to gprs in the current network.
Does anybody have an idea what I can do?
Thank you
Do you have all the appropriate settings for GPRS for the new carrier configured?
Yes i did. Settings are correct and GPRS worls with the original carrier SIM. And the new SIM works in an old BlueAngel. I guess, since the device tells me immediatly that I cant connect to GPRS, it is still SIM locked in some part. I already tried the free SIM unlocker from XDA-Devs.
Do you have an idea?
Does the Trinity make/receive calls with the new SIM? If so then it is not SIM locked.
It sounds as though you are still trying to use the GPRS settings for the original provider, this will not work for a different carrier, i am assuming the new SIM is from a different carrier.
GPRS settings are carrier specific.
Are you saying that the GPRS works in the BA? If so have you duplicated the GPRS settings from the BA?
Hello,
I have an (apparently) unlocked MDA Vario III. I originally tried with a virgin UK payg sim, and also a T-Mo UK sim, but no matter what settings I try, whether on standard Rom/Radio, or custom, I cannot make the data connection work.
I'm currently on the stock T-Mobile Rom and Radio, with factory T-Mobile data settings. Even that, with an activated T-Mobile sim gives me the "Cannot connect to the network for an unknown reason" error message.
What could be causing this? Have I scuppered the phone by trying to unlock it? Could it be the SPL? (That's the only non-stock thing currently on there). Is there a way to generate some kind of log to work out what's going on?

hi had a search around but unable to find anyone who has had the same issue
unlocked sgs from UK t mobile to use vodafone sim.
all was ok till i changed the setting to stop 3g to improve battery life, sgs went to no phone signal (blue circle with line through it on top bar). put 3g useage back on but still no signal
had a look at my phone/status:
network = vodafone uk
service state = out of service
mobile network state = disconnected
if i set network automatically it says 'registered on network'
if i select vodafone from list i get 'your sim card does not allow connection to this network'
i have hard reset the phone, locked it and unlocked again, but still the same
also tried with o2 sim and get the same problem
== t-mobile sim still works==
is there a solution out there?
Try to manually create another APN
EDIT: my bad...you meant no phone signal. I have no clue but hope that you'll get the help that you need.
what needs to be entered in the fields?
i've had this happen on two phones..........one was due to me messing up the nv_data files. the other was fixed by reflashing.
take your pick
i haven't had the phone flashed
i only used ADB to get the Network Control Key which i then use to unlock the phone
can you suggest the next step for me
i assume the professional unlockers use a flashing method, should i get it unlocked by one of them?
its possible the imei has been blocked
if blocked tmobile customer service said that i should hear 3 beeps when i try to make a call, but i get a message that 'not registered on the network'
could it still be blocked even though i do not get the 3 beeps?
if it is not blocked is there anyway i can get this working on a vodafone sim?
Hello,
This is my first XDA forum post. And I am sorry for it to be about a trouble question.
I've recently bought a Xperia TL Lt30at that is AT&T from ebay.
Anyway, I am planning on using it in Mexico from time to time, since I live near the border, so I bought another carrier's SIM (Telcel) and was to unlock the phone.
But now that I called AT&T to get the Unlock pin number (for free) they told me the phone's imei was blacklisted.
Questions:
Can I still unlock it to use in Mexico with Tecel carrier even if the IMEI is blacklisted on AT&T?
and, Why after inserting Telcel SIM into the phone the SIM NETWORK UNLOCK PIN screen does not show? Do you know why this is not showing?
Could it be that the blacklisted IMEI is not allowing the Unlock pin screen to show after inserting another SIM?
Many thanks in advance

Thanks for the info. I've already done that and I checked the IMEI number, that is how after calling at&t to unlock my phone they notified me that the IMEI was blacklisted.
The phone has 10 unlock tryouts left.
Do you know if this is causing the phone not to show the SIM NEWTWORK UNLOCK PIN screen after inserting an invalid carrier SIM? Because I can reproduce this from any video I have seen.

no , blacklisted imei is not the reason ; when you insert invalid sim, what is happening? does your phone detect sim and is there any signal?

That is the thing also. I had a regular size SIM card from another carrier, I cut it using a template to fit the Xperia TL that uses MicroSIM (I tested that it still works on phones that use the regular size) and when I place it inside the TL it does not recognize the SIM like it is not there.
Could it be that I need to get a real MicroSIM from another carrier to display the SIM UNLOCK NETWORK PIN screen?

yes of course, you need good micro sim card, phone does not detect sim card because it is not well cut; if the phone works perfectly with other sim it means that there is no damage to sim slot; i also have got xperia lt30at; I cut micro sim using template and it worked fine; when there is no sim card detected, the SIM UNLOCK NETWORK PIN screen will never appear
Thanks for your help, I have gotten a new microSIM from my carrier and it works. Seems the other one was very old and not even cutting it would have worked.
Now it does display the SIM UNLOCK NETWORK PIN screen after inserting it.
Yo don't know if you unlocked it yet but I just unlocked one for sell n it can't be blacklisted cause all the networks have the imei number n it won't allow the phone to work?

I just bought this phone off of someobr , it is a ATT phone. Says this on the back and in settings and at confirmed with the imei that it was. But when I enter a att Sim it prompts "Sim network unlock PIN" as if I'm trying to insert a Sim from a different carrier
Any ideas?
