thanks
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?
Dear all,
I have an issue with my Omnia 7 and need your help. My phone is Unlocked T-Mobile Brand. I can use SIM cards of several company except the one I use regularly. When I insert this SIM, phone is SIM locked and phone function is not working at all. When I press on phone tile, it brings me to home screen. SIM card from other providers work fine. So it is strange to me.
Could you help me? I want it to work with this SIM.
Thanks
That sounds very strange. Surely it must be something to do with that particular SIM card if your phone is SIM unlocked and other providers are working?
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!
Greetzz!

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!
Greetzz!

I have tried every code mentioned, in here, that was successful for others but not for me.
I started by buying my Galaxy S4, out right, at Walmart for use on Family Mobile. Poor signal everywhere except in my house. The phone has T-Mobile support as far as towers go. After about three weeks I had my phone number transferred to Straight Talk and they sent a SIM card for use with AT&T support. The phone was purchased as an unlocked phone, I did all the codes in this forum to check and sure enough, it is supposed to be unlocked, BUT, every SIM card I get from Straight Talk gives me "INVALID SIM CARD" when I boot up the phone then a black screen comes on with a subdued color message saying, "Sim network unlock PIN" and all the help from Family Mobile, T-Mobile, Straight Talk, Walmart and AT&T, have not helped my situation. I can't write a new APN and store it because I have an invalid SIM card. I have tried the service mode and did everything mention in these forums but no luck so far.
I really like the device(my NOT-Phone) but it does not function as a phone. Can anyone help with this one?

No warranty in Walmart?!
If it connects to T-Mobile towers out of the box, can you borrow a T-Mobile SIM from soneone and go through the SIM unlock procedure? I'd do that just to make sure it's SIM unlocked. Then try Straight Talk with whatever APNs they use. Do this on stock and once you can confirm you get that far and it's working then go crazy. Good luck.
Locked SIM card

If I put the original, 1st SIM (Family Mobile) that I bought, back in, I do not get the Unlock Sim code message but I also do not have service because I already had the number ported. I've been that route. I tried the APN routine but it won't save because I don't have service with that SIM card. I go into the unlock routine through the service mode and it says it's already unlocked. Any Sim card from Straight Talk gives me Invalid SIM.
I'm going to return it to Walmart and try another phone.
