[Q] Sim unlock for T-mobile Nexus 4?

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!

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!

Note registered on network

I swapped sim card on my cell phone, i have n9005 (running 4.4.2 TouchWiz Rooted) and works on every network in my country,
the other sim card worked fine, i kept on swapping 2 sims because sometimes i had to use 3g on the other network.
Today it suddly stopped, now my both sim cards are not working.
I have restarted my phone, pulled out battery and also reinserted my sim card, no success.
Any solution?
EDIT: I fixed it, thanks

You probably have damaged something in your sim card slot probably a pin.. as you said you usually keep on swapping sim cards.. have a repair center look at it..

From what I can see on http://www.telus.com/en/bc/mobility/network/coverage-map.jsp Telus doen't operate a 2G network. The sim that is not using data uses only 2G network, and there is the problem for you

I use two sim from same carrier and no issues, my carrier support 2g/3g/lte, sim with data on is 3g/lte and sim without data always fall to slowest network
If your carrier only support 3g you won't be able to use two sims.

Would some one give me a hand setting my Note 3 up.

So I purchased a used note 3 ( N900A )
I just switch to straight talk. So I had a full size sim and cut it down to fit my note 3 . When I try to go into my apn setting it says insert a sim or something like that.
I know the sims registering , to the phone I can read stuff from it.
So has any one went down the road I am . Is my sim locked or something like that.
Also there is an app called "Sim App." it will first say icc-id and give what looks like about 15-16 numbers then click ok it reads imei check sum gives 4 digits next reads random number gives 8 numbers.
then asks for an unlock code . If entered wrong it will say you have X amount of trys lefts.
Does this have anything to do with why my sim card is not registering to the phone?

Do any sim card works in the phone? Does your sim card work in other phones? Was the phone tested with a sim card before purchase? Was the phone locked to AT&T?

Yes if I switch the card to the other phone . It works.
Im not sure if this matters the orginal phone was a throw away`alcatel. Its not a smart phone.

Are you using the SIM card in another phone that also uses a micro sim? Does the note 3 recognize any SIM cards?

I only have this one sim .
The note is reading the sim card with certain aps . You know how if you up power up a phone , missing a sim it will say so if you pull down the top banner usually with a message like insert sim. When you pull down the top banner it doesn't say that . There is no warning about missing a sim . So it recognizes it has one . I can read stuff off the sim card when i open certain aps that are meant to access sim cards but when I go to change APN setting it will say insert sim card to access network settings.

Without another sim card to try in the phone, it could be the way the sim card was cut or there is something wrong with the phone.
Is the phone sim unlocked? Did you try a sim card in the phone before buying it?

I dont think the phones sim is unlocked.
No I didnt try a sim . It was from a family member so Im not to worried. The sim card works in my throw away straight talk phone.
How do you unlock the phones sim?
BTW thank you for your help.

In order to determine if the phone is sim unlocked, power off the phone, insert a sim from another carrier, and power up the phone. If phone asks for a network unlock code, the phone is not sim unlocked and you will need to get an unlock code.
Was the Note 3 n900a from AT&T?

Xperia Z5 Dual Sim Card - doesn't support 2 sim cards of the same network

HI EVERYONE,
Hope you can help me or give an advice...
I got Xperia Z5 Dual Sim Card phone. I'm on UK network. If I use both sim slots with the same provider, one of the slots stops working immediately. Shows no signal bars whatsoever. As soon as I use two different sim cards from different providers, both work fine. I called my network provider, but they state it's a phones fault.
Has anyone experienced anything like that?

Can you buy new sim card? And try with the new one

Could it be your carrier doesn't have GSM coverage in your area?
I think 3 in the UK does not have GSM. When you are in 'dual standby' mode one of the SIM cards MUST be on GSM only mode, therefore if your carrier doesn't have GSM it will never connect. This is a funny limitation, but it's what allows for dual standby phones to be made relatively simple without having to have two radios for two carriers, which would make the phone a lot bigger and complicated.

I went to the actual store and swapped the sim cards, but nothing helped

I never thought of that... It's strange as I went to Vodafone store and they said they don't support dual sim card phones at all.
I am actually with network 3, so thought there shouldn't be issues like this. Another funny thing is, that if I swap the slots with the same network 3 sim cards, sometimes slot No1 and sometimes slot No2 isn't working. As soon as I put one Vodafone and the other network 3 sim cards, both slots work just fine

I used my Z5 Dual when I was in the UK and was having real problems getting the EE sim card to work on the data side, it seems that when I put in the EE card my phone restarts (annoying but standard) and it resets the data preference to 3G which meant that I had no coverage. As soon as I switched the data preference to LTE it was up and running full guns again.

Thanks for you answer. Seems that it's more to do with the provider then the actual phone.
Sad that phone like this couldn't be used to it's full potential
