I am a little confused? Cricket can take your vzw phone and flash it to work on their network. What do they have or know that the devs at xda don't know?

The Verizon Note 4 is SIM unlocked. All it needs to work on Cricket is a Cricket SIM (and possibly adjusted APN settings for data and MMS). There's no flashing of any kind involved.
Um not mine,tried all carriers Sim cards the only one that worked is a old tmobile Sim from germany.

Then either something is wrong with the SIM cards you were using, the settings are off, or your device is defective. The Verizon Note 4 is SIM unlocked. There are plenty of threads on the forum where people talk about using it with AT&T, T-Mobile, and prepaid carriers.

cricket up and running on mine (vzw sm n910v) had to manually enter network apn to enable data , but phone worked upon sim insertion. It registered as an AT&T sim and I received an error message stating it wasn't a Verizon sim card but noone at cricket was needed to receive service.

The Sprint version is being advertised as an international phone, and comes with a Sprint SIM card pre-installed, and what appears to be a security strap, making it difficult to remove.
Before traveling internationally, you can call Sprint ahead of time to have them active their SIM card, and for the low low price of $1.99/minute, you can use overseas GSM networks to make phone calls, and in many cases, data access.
Of course I'd like to buy a pay-as-you-go SIM card and install that for much more reasonable rates while overseas, but I'm not sure if it's as simple as plugging in a different SIM card.
I had read that the Rogers version of the phone required...something to active the SIM slot, and even then seemed not to work for data via 3G.
Anybody else have the Sprint version? Played with GSM yet?
I'm a little apprehensive to start tearing into it to remove their SIM card just yet...
The GSM is 2G only, no 3G.
Well my buddy has a AT&T sim card that i put in my TP2 but it did not work. I switch the phone to GSM only but it did not pick up a network. I also put that sprint sim on his phone but it had no network either. According to the manual its lock from going to a gsm network on the USA.

Hopefully a custom ROM can unlock the ability to use GSM networks in the United States!

good to know.
I read in the manual that it was not usable on US GSM networks too, but I assumed that was because they never intended for you to remove the Sprint SIM card, so of course the Sprint SIM card wouldn't work domestically.
So it seems the Sprint phone can be unlocked for GSM just like the Telus phones, but I haven't read of any success getting GSM 3G to work w/ an unlock code.

Check the specs, if it said gsm 850,1900 it should be able to use with in the US. Just have to sim unlock it first in order to use.

What do you mean by unlocked? Do you mean Hardspl or do you mean Sim unlock? If you only dead a hardspl then you can't use another sim. Go here for the sim unlocker
http://forum.xda-developers.com/showthread.php?t=555339
you could try calling t-mobile and seeing if they'll provide the unlock code for you.
Tell them you are going overseas for business and need the device unlocked. This has worked for me with at&t and t-mobile.
I agree it sounds like you didn't sim unlock the phone
come on guys, its obviously SIM unlock if trying a different sim card..
it took my activation number (got it from tmoblie) clearly said the phone was SIM UNLOCKED, then i put the boost sim card, it said "network locked"
i did not try any other card yet, maybe boost sim cards are not supported, but ima test a at&t sim card to see if it works.
I know someone here must of have "NETWORK LOCK" after they SIM unlock there phone, please help me out.

Just my 2 cents for what it is worth. You might want to call boost and see if your sim is locked to an imei #. I know ATT has been using locking sim cards on prepaid for a few months now. Worth a shot
i would say your problem is coming from boost mobile and not from the phone itself... as the person above me mentioned ATT has started locking sims to phones when you buy prepaid sims, not a longshot to assume boost and t-mo will start to do this as well (if they havent already)... or it could be that boost isnt actually a gsm carrier even though it uses sims... not sure about that.
edit: i googled boost mobile technology type and they are owned by sprint... to the best of my knowledge even if you get your GSM phone unlocked it is still not going to accept a sprint (or boost) sim card.
why not, isn't the tmobile one still wcdma and gsm?
like i said... to the best of my knowledge... i never said my knowledge was any good.
can anyone confirm this?
edit: i did some more googling and all the people who asked on yahoo answers and the like got the same answer, no, your boost sim will not work in a GSM phone... i beleive if the tilt 2 were capable of both technologies it would have to have slots for both sims as well..
and to the OP, if you can get a buddy with an ATT sim to try it in the phone this will give us a definitive answer whether or not its the phone or the sim causing problems.
Boost uses the Nextel iDEN network. Although iDEN and GSM both use sim cards they run on different networks. Your Boost sim is incompatible with a T-Mobile TP2. Sorry.

+1 Boost is like Sprint not GSM
When I take the SIM from my AT&T One XL and try using it in an unlocked AT&T i747 (updated to stock, unrooted LH9) i'm thinking of buying it gets no data connection and only an occasional phone signal--and i'm in a good signal area.
Most of the time the i747 thinks there is no sim installed. For instance when I go into Settings->More Settings and try tapping on Mobile Networks the message 'Insert SIM card' is displayed.
I tried factory resetting the phone, no change.
I can swap my SIM into my wife's One XL and everything works fine... my wife's SIM works fine in my One XL. But neither my sim nor my wife's sim works in the i747.
I chatted with AT&T cust svc and they told me they have to register the IMEI of the new phone every time i want to swap SIMs which as far as I know is complete BS. Isn't the point of unlocked GSM phones easy SIM swapping?
I also tried shimming the SIM in the i747 with a sheet of paper in case it was loose. No change.
Any thoughts? Bad radio hardware? I'm there is something wrong with the i747 since two seemingly good SIMs won't work in it.
Might be a bad unlock aswell. Call att if your brave.

After many unsuccessful attempts i entered the secret code to check lock status (*#7465625#) and after it ran returned with:
'Connection problem or invalid MMI code'
But is that about lock status or that the running the code was in error?

I am on Rogers and can and always have been able to use my sim in any of my Rogers or unlocked devices. My wife on the other hand, is with Telus, and she cannot use her sim on any other device without registering the device first. There might be a self help online method if I recall. So it possible you have the same sort of deal is Telus?
Solved--exchanged phones at at&t service center, now have 4g on my s3 with same sim as i use with One X.
I have Verizon, a Motorola Razr (Not MAXX) and it is crapping out on me, running slow, not sending picture messages etc.
My boyfriend has a trading post type store and he bought a brand new Galaxy S3 but it's through AT&T. When I put my SIM card in the S3 it asked for a SIM Pin for unlocking.
I have experience rooting a Nook Tablet so with some directions I'll probably be able to do it, I just don't know where to even start. Do I just unlock the phone or is there a way to switch it over?
Thanks!!

It seems like you just need an unlock code to use it with your old SIM.
http://forum.xda-developers.com/showthread.php?t=1962453
Try taking a look at this thread and see if you can get an unlock code from AT&T.

So I called AT&T and they gave me the unlock code. I used it and it said unlocking the mobile network was successful. I tried to make a call and it said that only emergency calls were available. I restarted the phone and when making a call it said no mobile network can be found.
Ohhh you are putting a Verizon sim card in it? I don't think that will work since Verizon's network and lte use different technologies than at&t and the sim card is encoded to use the respective technology :X

Yea I have a Verizon SIM card. On my verizon RAZR I have the option to switch betwee CDMA/LTE, Global, and GSM. I know AT&T run off GSM but if my Razr has the option to switch does the S3??

That would mean you can insert a gsm sim card into the RAZR maxx because it is a world phone. However, the at&t s3 does not support CDMA, which is the network technology that Verizon uses. That's probably why you are getting no mobile network when inserting your Verizon SIM card in the AT&T s3.
Sent from my SGH-I747 using xda premium
The gsm sim that comes in Verizon global phones is there so when you travel out of the country you can use a cdma phone in countries that have a primary backbone that is gsm. In the us your phone uses Verizon's cdma network. If it does not see that network it will then look to the sim card to see if global gsm networks are detected.
To my knowledge this is going to be a no-go. If you have not done so, clean up your sd card, toss a factory data reset at your razor. These android phones are pretty tough.

It got a signal. But could not pick up carrier or anything just had signal and said searching in notification bar.
But verizon is CDMA so it did not supprise me.
I see that the LTE radio bands are in there, no surprise there. But I also see WCDMA radio bands too. Does that mean that our Galaxy Note 2 have WCDMA radio too? Or is this just an firmware that Samsung uses across all Galaxy Note 2 devices?

I think we have CDMA also....not that it does much for us as verizon and sprint require the imei to be loaded into their systems.
WCDMA != CDMA by the way. WCDMA is 3G/4G GSM (aka UMTS)
CDMA is a competitor to GSM. It is used by mainly North American and Japanese/Chinese cell phone companies.
I know Verizon and Sprint in the US and AU in Japan use CDMA. Most of the world uses GSM.
All though thinking about it while we may have the CDMA radio, assuming it is the same chip as the GSM and LTE radio then they may have just not sokdered the connections. Seen that before with FM radios built into the bluetooth chip on the Atrix 4G
Which of the bands are our 4G?
Love learning.

No problems. This kinda stuff is my hobby. Maybe some day I can get a job at a cell phone company as a technician or something.
I can confirm this works, but I could not get data. I got signal and a carrier name with both an AT&T sim and a Straight Talk (AT&T) sim. It would not load APNs, and I don't have the APN for regular AT&T so I tried with the Straight Talk, put in their APN and still got no data. Neither sim is active currently. It did allow me to call 611 on both sims.
