[Q] Unlocked AT&T phones can verizon sim be used?

I am looking to purchase an AT&T Galaxy Note 2 and need the following question answered... I am aware of the unlock link http://forum.xda-developers.com/showthread.php?t=2014982 that uses the method of dialing the following keys *#197328640# but here is my concern... Does this method allow you to use a Verizon Sim as if you had purchased a Verizon Galaxy Note 2? In other words does it unlock the CDMA band also?
Thanks for any correct information...

Until vzw goes to VoIP in the next few years the only thing the sim supports is 4g data. Because lte is a gsm based network, sim cards are needed. Nothing else in a Verizon phone used the sim so no you would not receive full service using a vzw sim. Not sure if you'd receive data or not but I'm betting no

Verizon uses CDMA for voice, and CDMA/LTE for data. Not only are the LTE frequencies incompatible, but CDMA is incompatible as well. So no, the Note 2 will not work AT ALL on Verizon.
Also to note, Verizon will only let you activate VERIZON BRANDED phones on their network. You can't buy unlocked phones and use them like a GSM carrier (AT&T, T-Mobile in the US) would. Sprint is the same way.

Ok, so if I purchased a Verizon Galaxy Note 2, and rooted it, I could then use AT&T and later if I finally want to switch over to Verizon, I could... If I am mistaken about this, please let me know. Because I am trying to get a Galaxy Note 2 that will work with both GSM carriers and also work with Verizon when/if I choose to switch.

No. Verizon and AT&T phones/networks are not compatible with each other at all.

This does not exist on ANY Note 2 on earth. Possible with *SOME* other phones, but not any Samsungs, and definitely more trouble than it's worth. NONE will be LTE compatible though. 99% of the GSM compatible phones on Verizon are locked on only work internationally, and will not work AT ALL for the US.

I've been wondering about this. Can't the Verizon "international" phones be unlocked, then used with a US SIM?

"Yes. Verizon GN 2 on AT&T network. Phone is rooted. AT&T APN added with APN Manager Pro. Decent speeds too with just 2 bars. Sent from my SCH-I605 using Tapatalk 2"
Just pulled this off of a different thread... http://forum.xda-developers.com/showthread.php?t=2044449
Seems like the Verizon GN2 can do AT&T with data, as long as you rooted and adjust the APN file. If this is incorrect please let me and the rest of the form know how or why this is incorrect....

I already said data "could" work. That'd not the issue. Getting everything to work is what seems to be unlikely. Different frequencies for voice/text.

Any new Verizon phones can work on any GSM HSPA+ network with some trickery or are unlocked out the box. Some phones work on At&T and T-mobile while others only work with carriers outside the U.S. YMMV.

Buy a new Note 2 or unlock my current one?

I'm currently on att with a note 2 and i've switched to t-mobile and will be recieving a new phone in the mail soon. Should i return it and just flash a t-mobile rom onto my current phone? or should i just sell my att one on craigslist and keep the new t-mobile phone? Any possible loss of features or functionality by sticking with the phone i have?

I don't understand your answer to the OP.
I'm in the exact same situation as the OP. I'm with AT&T but they just took my unlimited data plan away so I'm probably going to switch to T-Mobile.
Are there any bands that the T-Mobile Note 2 has that can't be unlocked on the AT&T model? According to Wikipedia both AT&T and T-Mobile version of the Note 2 have AWS. I heard that you can enable the high speed bands on AT&T's model to work with T-Mobile. Is taht not true?

Tmo hasnt released the update to let tmo gnotes2 work on their lte network, because its not up and running most places... Possibly only update customers who are in Kansas City.
Not too clear if att gnotes2 with att specific firmware would work on tmo's network. Theoretically it should work, but their might be some radio issues that give u shoddy service. Unlocking phones is illegal now, so idk if u could sim unlock ur phone through att to work for tmo anyways. Might have to go through ebay or something to do so.

Can I take my rooted Tmobile Note 3 to Verizon?

I moved to Charlottesville, VA recently and the Tmobile coverage is really awful. Is it possible to take my rooted Tmobile Note 3 and use it on the Verizon network? I know it works on AT&T as I put my buddy's SIM card in and was able to connect to the network, but Verizon has the best coverage out here.
If I have to flash a new ROM or change the radio that's fine, I just need to know how to do it and if it's even possible.

No, not possible.

It is impssible to use a T-Mobile phone on a Verizon network. T-Mobile and AT&T run on the GSM type of network and Verizon and I believe Sprint run on CDMA which aren't capatible. It doesn't matter if you are rooted or not.

I've seen several instances of Verizon customers using their Note 3 on Tmobile. Just thought it might go the other way.

Verizon LTE devices come SIM unlocked for legal reasons (Verizon made a deal with the FCC not to SIM lock their devices in exchange for being able to use LTE Band 13 700 MHz).
Some of their older/"first-gen" LTE devices don't support GSM at all (e.g. Galaxy Nexus). But all nowadays do. The Galaxy S4 and newer support T-Mobile's LTE band. LTE is a GSM-based technology, and people travel as well. So pretty much all of their phones are GSM-enabled nowadays. Same for Sprint (except their phones will reject any US carrier SIMs specifically).
Anyways, the answer is no. AT&T and T-Mobile devices don't have CDMA enabled. And even if they did, Verizon and Sprint don't allow competitors' phones onto their networks.

[Q] T-mobile note 3 on CDMA network?

Is it possible to use the t-mobile note 3 on a cdma network? I don't intend to use it with verizon or sprint but I recently heard of ting and it looks promising. I was curious if, through flashing, it would work.

No. This question has been answered MANY MANY times in the past.
The reason Verizon and Sprint (maybe) models can be used on TMO or ATT is because those CDMA models use GSM for LTE, thus having BOTH radios. The TMO variant DOES NOT HAVE A CDMA MODEM. PERIOD.

Buying Note 4 but Want Root, Can I buy a Tmobile/ Att to Root then Switch to Verizon

Hey guys!
I have a note 3 and its EOL. I was waiting for a Note 5 but I guess I dont have time now. I like the S6 Edge but it does not have key features I want (expandable memory card, extra battery).
This leaves me back with the Note... What's the best way to get it Rooted for Verizon? Can I buy it from T-mobile / ATT Auto Root it then switch it over to Verizon? Thoughts?

The other variants don't have the right bands in them for Verizon. I believe your only option is to pick up a developers edition.

Incorrect. They have the same bands for Sprint/Verizon/ATT/TMobile ect.. but IME's have been white listed and/or bands have been locked by the carriers. Global phones typically have all the bands necessary.

Your statement is also incorrect in part, as the T-Mo and AT&T phones lack the CDMA radios required for Verizon.

You will need to get your phone unlocked first.

I worked at VZW for 3 years in Tech Support. You can not take another phone from any other carrier (except the old Altel phones) and use it in Verizon with the exception of global phones with global sim cards. Verizon uses A-Key authentication which prevents taking a Verizon sim card and putting in a non-Verizon phone and using it. Verizon used CDMA unlike all the other carriers.

That really stinks, anything I can do on the Verizon Note 4?
