What does the author meant by SIM Free? Isn't it just taking the SIM out considered as SIM free?
removing simlock so any providers simcard can be inserted without the problem that the universal blocks the sim
for example: my mda pro is locked to t-mobile. if i insert an o2 simcard i cant use the phone function, it only works with t-mobile simcards.
with this unlock i can use any providers simcard i would want to

Do you mean it is blocked in the UK? Did you get it as a second hand?
No, its new. it isnt blocked, its locked for vodafone uk network, but is sim unlocked.
Yep, that's what this is all about. It's not really to remove the SIMLock, but more specifically a NETlock which locks the device to a specific provider/network.
Or probably both, but I don't know if there is even any SIM-locked Universal out there. I think if the Universal comes with a lock it is generally a NETlock AFAIK.
SIMlock is usally used for chreaper prepaid bundles and NETlock for higher priced but branded devices.
Hi
I would be very grateful for some help.
I have just received an unlocked US G2 (not a UK desire Z).
I live in the UK and was previously using an iphone 4 on contract with O2. When I insert my sim card and turn on the phone I get no network service.
I was under the impression that the american version should work in the UK. Does anyone have any suggestions?
Thanks
Nick
Are you sure it's unlocked? I use an American G2 on T-Mobile UK and it works perfectly. But I unlocked it myself after importing it.
Check to see if its been set to 3G / HSDPA only... O2's 3G network isn't the most expansive..
Its in settings / wireless / mobile network / network mode..
It should show "GSM / WCDMA auto"
Craig
I reckon try the gfree root, s-off, super cid from the Development forum.
Thank you for the quick replies
The phone was advertised as unlocked however this may not be the case. On the G1 when I inserted the same sim into a locked unit a message appeared on screen informing me that the phone was locked. This did not happen with the G2 - it simply has no network service.
Is there a simple way for me to check the locked/ unlocked status?
Nick
Weren't there issues with unlock codes? Me thinks so.... I'll have a search.

.... So use Gfree Root & Super CID!?!
.... So use Gfree Root & Super CID!?!
This worked - phone was obviously not unlocked
Thanks!
Nick
...do I unlock the phone now that Android is installed?
Should I have done a SuperCID on it when Windows was still installed, or is there a way to do it now, too?
if you mean sim/network unlock, its completely unconnected to roms/flashing/hspl or any of that.
there is no free unlock, you can only get it unlocked to other networks by getting a code off your provider, or paying for one from teh many companies that offer the service.
So, what happens when you stick, say, a Vodaphone SIM in a T-Mobile HD2?

The phone asks for a code if it's sim locked. If it's unlocked, then it will detect the sim card and connect to Vodaphone's service. The only thing that doesn't always work is 3g data, if the new network doesn't use the same frequency bands as the carrier the phone was made for. Like if you put an AT&T sim in an unlocked TMOUS HD2, you can make calls and use 2g data, but 3g won't work.
Hello everbody,
i read all threads related to SIM unlock on T-mobile nexus here on xda, and many people suggested that Nexus 4 comes factory unlocked, even from T-mobile, but it seems that's not true!?
I wrote about this in thread bellow,
http://forum.xda-developers.com/showthread.php?p=38939958#post38939958
and many people there wrote that Nexus 4 is always factory unlocked, doesn't matter which GSM provider, but it seems that's not true!
When i inserted my european SIM card, here in Europe, in T-mobile Nexus 4, arrived today at me, GSM signal is locked !? Is there any solution for sim unlock?
Thanks!
Greetzz!

****update
it was problem with micro-sim card and pin issue, tried with another sim card, and no problems, it's unlocked, and fixed gsm signal very fast with working micro-sim card here in Europe !
Apologize for wrong info!

It`s not locked! Change your sim with a proper microsim!
It seems you didn't read my previous post, i wrote, micro-sim card is already used, but there is again GSM signal locked!
***update
My apologize to all of you guys! It was problem with sim card, not about micro-sim, but there was problem with PIN of my sim-card, so definetely, it works now, with another micro-sim card with no PIN issue, it worked immediately, GSM signal came very fast!
Once sorry!
And tnx for suggestions!

nexus 4 isnt sim locked. check to be sure that your APNs are set up right for your carrier. why do you think its locked? are you not getting a signal or do you get a locked message? have you checked with tmobile to make sure your account is set up right?

1) Can you take a screen shot of the message you get while on WiFi?
2) Are you sure it's Carrier SIM locked and not "SIM card lock"?
3) Was your SIM card cut down from mini to micro?
4) Are you sure it was not reported Lost / Stolen and it's IMEI blacklisted by the carrier?
5) Have you tried another SIM from a different carrier?
As far as I know, all GSM Nexus phones do not support the option for carriers to lock them to their networks.
I had a Nexus S that was subsidized by T-Mobile and it worked just fine on US AT&T, and France SFR networks.
The SFR SIM I used had a PIN on it, so I would have to enter the PIN on boot before I could use it.
Its an unlocked phone...
If it was locked, when you insert a foreign Sim into a carrier locked phone, it pops up a requester for an unlock code.

You are absolutey right my friend ! Hehe, yeah, but you know, when man feels like a lost , can't think with rationalism, so i was afraid i'm lost and there is phone sim locked, but there was stupid problem with sim card!
So to conclude, definetely no locked Nexus 4 with or without contract, it can be used with any sim card and GSM provider !
Once Big Tnx to all nice guys who participated in this thread to help me! Really i appreciate it!

Did you received any sort of OTA when Sprint unlocked your phone?
Currently Sprint claims that they just mark the phone as unlocked in their DB and then you need to restart it.
It clearly doesn't work for many, the phone still shows "Invalid SIM" message and the consensus is that this is not normal and the phone is not unlocked.
So the question for those who have their phones _successfully_ unlocked, was there anything in addition to Sprint saying that they unlocked your phone?
when sprint unlocked my phone? I don't follow?

You call them (or chat) and ask to unlock the phone to be used with 3rd party GSM carriers. That's what I meant.

I don't know if my phone has been successfully unlocked - but I can swap in a US T-mo Sim and it doesn't show an Invalid SIM message on my phone.
I only got an Email from InternationalDeviceUnlock <[email protected]> with the following message
Hello xxxxx xxxxxx
This email is intended to confirm that Sprint has successfully unlocked your Samsung Galaxy s4 Device. Please follow the steps below to unlock the device after you have the third party SIM:
Turn off device > Insert 3rd party SIM > go to Settings > More (tab) > System Update > UICC unlock. You will receive the update and it should change to GSM Mode.
Phone number: xxxxxxxxxx

it wont work on tmobile
tmobile is on different bandwidths when they say unlock they mean international not any us carriers and even if it did work you would only get edge no 3g or lte

no, tmobile and att bands are supported by the hardware.. but are blocked by samsung/sprint regardless of unlocked sim status. if we can unblock it 3G would also be supported. WCDMA band support on the Sprint GS4 includes 850mhz and 1900mhz... so that means 3G works just about everywhere for ATT... and Tmobile would have no AWS band support but would have 3G in areas where Tmobile has refarmed 1900mhz.
Again.. the hardware itself supports these bands... its just an extra block thats stopping us. I am working on the unblock for ATT/Tmobile.
And to the OP @obender, @jj14's post show exactly what Sprint sends when the device is unlocked. Other than that... go thru the steps and that's that. As jj14 also states.. he can pop in a tmo sim and gets no error... proving he is truly unlocked.

I had my phone unlocked, and I did the above as per the email I received. However it just said that the profile had been successfully updated, which was the same thing it said before it was supposedly unlocked when I pressed UICC unlock. It also didn't change to GSM mode automatically. So I wasn't really sure it had worked, but I was able to put in the AT&T SIM from my Nexus 7 and I didn't get an invalid SIM error.
When I went to Costa Rica, I was successfully able to use my phone with a prepaid SIM (GSM and HSPA/WCDMA). That said, I had to go into the Testing menu and force it to use only WCDMA, otherwise it would only use GSM/EDGE (even selecting WCDMA preferred didn't work... it would switch back to GSM pretty quickly). I also had to make a build.prop edit to be able to add an APN to use data. So you basically need root if you want to use data.

You seem to be digging in the unlock for the S4, but are you just working on domestic, or also international unlock. Have anyone tried pulling all the nv items before and after the unlock?

I just recently got my S4 from sprint I had them unlock it for international use all the available networks now show up, but in regards to invalid sim msg I will not know till the end of September when i am out of country. and on a side note if you call Sprint before you own the phone for less than 90 days you have to go through a lot of loops but they will unlock it for international use. out side of that I am unsure as too how far the unlock actually goes.
will keep you updated as to my findings I will be trying a different sim card while over there
