The SIM card may be locked to the device it was activated on. I suggest going to a T-Mobile store to see if they can help.

i tried 3 sim card ... DId they lock all the sim cards?? .. thanks for the suggest i will go to t mobile today
It is likely that they lock the cards to the device that the card is activated with. It seems like it is the only possible reason that you can't use T-Mobile cards.

I went to t-mobile. They tried another sim car and the phones was the same no sim... the said that the problem was with the phone cuz the sim cards are news and working on other phones... i dont know why the problem is only with t-mobile sim cards.. they say that if the phone was from t-mobile they could change me for another phone but it is at&t.... do u you think that it will be any problem if i go to at&t and tell the that my phone is unlocked but it doesnt read t-mobiles' sim cards

They could help. Might as well try. It is a very weird situation. If other SIM cards are working with it, it shouldn't be the phone...

Yes the problem is only with t-mobile... but i will take the phone to at&t tomorrow

Is it possible that you didn't unlock all the bands on your device? There is a tutorial around here somewhere that shows how to unlock all the bands for use with absolutely any carrier. From my understanding it is different then just unlocking with a code.
Sent from my SAMSUNG-SGH-I337 using XDA Premium 4 mobile app
Yes but it should said invalid sim car or ask me for that code when i insert t-mobile sim card... but the phones says no sim.. it doesnt even read the sim.... and when u unlock with a code i think is like factory unlock cuz my father unlock his phone with a code and his phone works fine

My phone has stopped working 3G for one day until now( i've used for 1 month) even I try everything such as active, deactive ,reboot, up rom,...but it didn't work at all. I can't see the signal of 3G on the top bar. I don't know the reason is. Could you please help me ?
(I use Vodaphone carrier network in Australia)
Factory reset?

I've done that but it did not work even though in stock rom or cook rom.
Could also possibly be a problem with the network... Masts do break down. Have you tried your sim in a different phone?

Hi,
I ordered the N4 the first day and yesterday it came here in Italy via FedEx, using a service called viaddress. I change my SIM and got a MicroSIM but when I insert it the phone ask me for the PIN, I put it but I get "No service". The Sim is recognized, but the network doesn't connect. I typed #*#*4636*#*# and it shows -95 db so the antenna is working but it doesn't register on the network. Can you please help me? Can I re-flash the radio? Or how can I get warranty, without spending much money? Thanks if you help me!
now it shows -0db but when I try searching for networks it find Vodafone, Tim, Wind but not H3G, which is my operator, please help!

Did you activate the microsim already?
I just switched the Sim, about 3 hours ago, maybe that's the problem, tomorrow I can tell you more
Sent from my Nexus 4 using xda app-developers app
Ok, now the antenna shows -99 db so I think it isn't an hardware problem but a software one, I'm downloading the stock image and I'll try to flash the stock radio, boot loader ecc.

Here in Italy is another day it still doesn't connect. I'll try to do a factory reset and re-flash the baseband. I don't want to send it in USA, it will cost me up to 50€
Sent from my Nexus 4 using xda app-developers app
OK now everything is working, I typed *#*#4636#*#* and in the network type field I chose WCDMA (aka UMTS) and now it's working.

Hi all,
Just wondering has anybody come into this issue before?
For some reason, when i use my Vodafone Sim card it gives me the LTE option.
However when I insert another sim card (e.g. my optus or telstra) it removes the LTE option.
Is there such a thing as 4G Sim?
Yes LTE enabled sims
Sent from my GT-I9505 using xda premium
No, it's not sim related, it's contract related. You have to ask to your carrier to enable LTE, and it will probably have a cost.

Had no need for it???? If your on Verizon the phone is NOT going to work without it... If you bought it to use the Sim card slot then why not just buy an actual gsm version

i used a knife as well lol, needed the number off it to get the new sim activated on it.
I used tweezers to remove it from the phone
Yeah you def need that card if you're on Verizon. I was having problems because I took my sim out of my note 2 and put it in my 3 and it wasn't working until 30 mins later I figured it out. As soon as you pick up or purchase the phone it auto stops your last sim.

I have been using the sim card from my Verizon Galaxy nexus with no issues so far.

Mine came with a sim removal tool or some such.
Yes, mine came with a SIM preinstalled. This phone is an absolute pain to remove the SIM from.
I used a small flathead screwdriver to remove it.
Tweezers.

I just used the point of a knife to gently push down on the card and slid it out.
Guys can anyone confirm if the phone is unlocked?
I'm traveling soon to the caribbean and need it unlocked and UMTS 900 to use 3g.

I used the sim from my Note 2. Kept my unlimited data. Tossed the pre-installed one out.

I ordered mine from a local store and they needed your account to pre order. So as soon as they scanned it as picked up it was activated because I had no signal on my note 2. That's how I figured out was preactivated from the store

You guys realize there's a SIM card removal tool in the box, right?
Granted, I couldn't figure out how to use the damned thing for a while. Ended up figuring it out though and using my old SIM.

That is not correct. I'm using the same SIM in my Note 3 that I used in my S4, Note 2, and GNex. The beauty of SIM swapping is awesome for phone addicts.

Made sure my finger was dry then kept sliding my finger across the card really fast to create friction then it slid right out.

I searched around but couldn't find anything to solve my problem.
I just bought a LG G2 D800 from Ebay, clean ESN and I double checked it and it was clean.
I unlocked it in CyanogenMod which only required 1 unlock code, but then reverted to stock 4.2.2 restore where there's 5 different locks? When I try to tap each it displays, "Your phone is not personalized".
I slotted my MetroPCS SIM in and the phone displays "Phone not allowed MM #6" on reboot.
Those are all the steps I have done so far to try and use my MetroPCS SIM. This is my first time ever using a GSM Phone, I have no idea what to do now. I've tried to look around Google and XDA and can't find my problem. There was no errors on the AT&T SIM.
looks like a carrier simlocked phone. Is it carrier branded?

Factory reset has done nothing.
Basically, I unlocked the phone, but it isn't unlocked.
Is there any way to reset the lock? Or something of that nature.
