With a Metro Sim, you need to call Metro to switch it over. It's not automatic with them.
EDIT: ALso, you need to change the APN settings for Metro to get data

You're lucky. Anytime you switch sims or put a new sim in a phone, you have to call MetroPCS. I've never been able to just put a sim in an unlocked phone or even a different METRO phone and have it work immediately. I have always had to call.

Unlock not working? Why?

I got the unlock code for my att note 2 it went through then it says sim not provisioned mm 2. How do I fix it so I can use it on T-Mobile
Sent from my SAMSUNG-SGH-I317 using xda app-developers app
Sim not provisioned mm2 means that the sim card tbat is currently in the phone is not activated on any network. Get a new Sim card and activate it OR just activate the one that is in the phone.
So after doing the free unlock trick, all we have to do is pop in a working T-Mo sim for it to work? No tweaking anything or flashing radios?
If you have an ATT device, you will have to load the TMO apn's for the device to work.
Radio image should work, but you may need to try a different image based on your location.
Apn settings are critical....g

Yes it will work..all you need is the tmobile modem..which will make the correct apns are enabled properly. ..
Clean rom for example is for multi carriers and you can flash it for att or tmobile. .just for an example. ..make surebyou have a updated good modem for that carrier...clear/cache dalvik cache install modem...reboot should work just fine. Did this on my note 1 and a tmobile guy bought it off me, I had the modem installed prehand and he inserted his sim power it on and bam..worked fine

[Q] Unlock SIM for StraightTalk

I just purchased an S3 (AT&T version) and want to use it on StraightTalk but it needs to be unlocked inorder to use the StraightTalk SIM, I have seen the websites where I have to pay $XX.XX and they will unlock it with the IMEI #, but there MUST be a way to do this on my own, right??
If I root the phone, and install a custom ROM will that have any effect on the ability to unlock the SIM? or whats the process to do this on my own?? (Is it possible?)
thanks in advance
Search. There is a free method to unlock. Also, if you have an at&t straight talk sim, you don't need to unlock it.

Use your own compatible or unlocked GSM phone on America's best nationwide networks. Select a SIM or SIM bundle to get Unlimited* Data, Talk & Text. It's that easy.

He is right... Should work right out of the box. Just need to set your APN.

I'm trying to unlock my phone, I bought used on ebay, I found found a thread here that shows you how to unlock, but can't even do the first step. when I install a different sim card, I don't get the message Unlock, the phone reads the sim as a non support sim.
the sim I'm putting in the phone doesnt have service on it, Is this the reason the unlock message doesn't come up?

I put a metro pcs sim that has service on it, but when I try to make a call, it say, not register to network, and or mobile network disconnected? Aso also tried to put the apn setting, but when I try to save the apn setting, they disappear??
Anyone have any idea?
Thanks for the reply
you can use free unlock from general http://forum.xda-developers.com/showthread.php?t=2024514
but of course you have to do it from uvkl1. but--you can do a nandroid, and after you unlock it, restore your backup! it will stay unlocked

Seems your phone's ROM/Radio mismatched or not for MetroPCS. This exactly happened to my phone also, until I flashed a new radio for my rom(I am using TMobile, flashed new TMobile ROM but not new Radio. Then it had the problems as you have now).
New sim fixed

The sim card I was putting in the phone was already register to a different phone.. I had to put a new sim, not active yet, then register the new sim to my imei and it worked fine.. I bought the phone used from ebay and it was already unlocked..

Question about sim unlock

Hey I have my sim unlocked I did it using the hidden menu method I have used it on simple and more recently metro. I got a new Nexus so this is now my backup. The other day I put my girls tmo sim in and it worked fine but today I put my mother's metro sim in and it wouldn't get a signal. But it didn't say insert sim. So did I inadvertently relock my phone to tmo by putting a tmo sim in it?
Also I am on cm 12.1 and I don't have a PC to Odin back to stock so is there a way to unlock the sim without having to go back to stock?
No re lock is possible.
There's no way you can relock your phone , it doesn't work that way, once is unlocked stays forever.

Need help unlocking LG G2 LS980 flashed to boost mobile.

Hey, I just need someone to point me to the right direction.
I bought my LG G2 off ebay last year, it came flashed to boost mobile. All I need to do is flash it back to sprint and unlock the GSM on the phone.
I just found this forum and don't know where to start in this process..
Im on 5.0.2
Software version LS980ZVI
Model # LS980
Thank you if you can help
this thread has everything you need
http://forum.xda-developers.com/sprint-g2/general/ls980-lollipop-update-root-sim-unlock-t3357837
After you install TWRP successfully but before you unlock the sim card, You can install the latest version ZVI that is already rooted
http://forum.xda-developers.com/sprint-g2/development/rom-ls980-stock-5-0-2-zvi-flashable-t3303163
for unlocking the SIM card I would use this procedure instead

Thank you !!
Since you are on ZVI already, you could try the steps in this thread

Hey I did all the steps and got it unlocked but I cant to get my simple mobile sim card to work.
When I select the network mode global I have full bars, but when I try gsm/umts all my bars go away.
The phone is reading the sim card, but im not able to make calls/text. I Also get a authentication error when I try to update the prl/profile settings
did you do the twoclick procedure to unlock the sim card?
did you edit your apn? from the dialer, dial ##3282#
i am on freedompop so i changed my apn to freedompop.foggmobile.com. Simple mobile might require it to be mvno.att.net or something like that( i used that for airvoice).

Yep I did the two click method but on both of my sims my phone refuses to connect/ find networks. I get emergency calls only.
I used a freedompop sim too and changed my apn to freedompop.foggmobile.com. but it still wont connect to the network. When I go into the freedompop messenger app it says. I dont have any data.

that;s strange. It worked for me as soon as I added my APN. Does your phone see the APN for three.co.uk and 3hotspot when you have the freedompop SIM in there?
I don;t even use the Freedompop Messenger app. i just use the sim for data. i can test the functionality of the sim slot because I have a freedompop CDMA/Sprint sim card along with a GSM one.
there are a couple of other ways to unlock the sim slot-they're all based on the same way so don;t know if anything will be different. there is a simfree.exe and there is a thread by someone named summercat for a 1 click procedure. try one of those

yep thats the first apn I see "three.co.uk"
im gonna tot back to zv8 and try this one more time or im just gonna go with ring plus or ting.
But thanks for all the help.
And you used ##3282# to add the new apn, correct?
I would go down to zve, then do the Ota update from sprint to zvg or zvh, then do the unlock and root and sim unlock. It's worked fine for me on zvh and zvi.

Yep, I enabled the lte/cdma, rebooted, then enabled gsm, rebooted and I got it to say freedompop on the lockscreen but after a couple of min. It went back to searching for networks.
im gonna try zve to zvg with the two click method
Good luck. The way you know it is supposed to be correctly installed is that your boot animation changes for the yellow sprint spark animation to some swirly wavy rainbow. The carrier image gets swapped to a gsm version.
