[Q] simultaneous voice and data - AT&T Samsung Galaxy Note 4

Is there really only one radio in the note 4 for AT&T ? he Verizon version is rumored to have two which is needed for simultaneous voice and data on the samsung note 4 for at&t. Anyone have comments on this?

There's no issue using data and voice simultaneously on the AT&T Note 4.

AT&T is GSM, Verizon is CDMA.

GSM allows for voice and data at the same time, while CDMA does not yet

Does the international Note 2 work on Sprint's Network?

Wanting to pull the trigger over at handtec, but do you know if the Note II will work on Sprint's network here in the states? If it's 3G only that's fine as the 4g/LTE isn't in my area yet anyways. And will not be until next year in which I would just upgrade to the Note 3.
It won't work on any of Sprint's networks, 3g or otherwise. You'll need to wait for Sprint to release it themselves.
Neither will it works on Verizon network. Both Sprint and Verizon use CDMA for voice, 2G and 3G data. Since the international version of GN2 won't have the CDMA chip in it, it won't be able to use the CDMA network.

Doesn't Verizon use LTE on the 700 band just like AT&T and future TMobile LTE?

Please correct me if I'm wrong, thank you.
Yes, they do, but there are different sub-bands on each frequency. I'm not sure you'll be able to use our phones on VZW, which seems to be where you're heading.
Even if you could for data, until vice over LTE comes, you couldn't do voice (cdma) on Verizon.

but can't you do voice with verizons note 2 if the phone is used with an AT&T or Tmobile microsim card?
verizon's note is capable of gsm as well and supports the frequencies of AT&T and Tmobile if unlocked, is that so?
aren't the phones from verizon sold unlocked?

Yes but their boot loader is encrypted so you will have a hard time changing kernels. Also I do not know for sure their note 2 is SIM unlocked. Most phones are but some are not (think iPhone which they wont unlock for use in US only overseas)

My T-Mobile Note 2 is sim unlocked. I can pop my own AT&T sim in it and get voice and 3G data no problem.
I tried the sim from my Verizon S3 in the Note and while it displayed signal bars for voice only, and any attempt to make a call resulted in a message about not being registered on the network.
Verizon is word about letting non stop Verizon phones on their network, and even if the phone is compatible on the GSM, that doesn't mean they'll just let you bring any device to the party.

T-Mobile Note 2 > AT&T Note 2 > Verizon Note 2
The above is an order in terms of which Note 2 is more flexible in switching between carriers,
Overall, T-Mobile has the best Note 2, right?
Agree or Disagree?
Winlinmac001: you have to sort out your priorities, get a phone, enjoy it and move on...
Pick your carrier first.
If its Verizon, then get their model, not much else to it really. Until they get VoLTE operational and ditch CDMA completely (many years to go) your phone has to be activated in their system. Expect no, or limited support for US GSM carriers.
If it's T-Mobile, one of their MVNOs (or even a non-LTE AT&T MVNO), or you want to be able to switch to those with a minimum of fuss: T889. The clincher here is the HSPA AWS support that you'll need to get any meaningful speeds in non-refarmed areas. From what I understand only T-Mobile has DC-HSPA (42 Mbps) whereas AT&T only has 21 Mbps.
If it's AT&T: are you in an LTE market? do you care for LTE? If yes: I317. You're certain to get LTE right now with this one, with no concerns about cross-flashing modems or waiting for some firmware update that could take a while to come on the T889.
T-Mobile
It's settled then; T-Mobile Galaxy Note II it is; especially since it is compatible with most networks compared to AT&T's variant; and that it is a true global phone. Thank you.

Is the hardware for the Sprint Version of the Note 4 and the T-Mobile version of the

I am wondering if the Radios for both phones are the same or different? I recent had my Note 4 unlock for international and domestic and I was wondering if the sprint phone can use T-Mobiles LTE network?
Has anybody tried this?
I do know that if you go to ther website and try to byod and go to supported devices the sprint note 4 is listed as being able to fully access the network.this includes their 4g lte.i tried a note 3 and does not support that device.a few years ago i had a windows mobile phone that was hacked to allow usa tmobile to be accessed (but not full speed data).i used prepaid sim card and had to have two numbers and restart phone to change provider.my voice mails would be waiting for me.

Verizon S4 SCH-I545 on T-mobile. Bands missing for voice?

Hi all,
I've been using a Verizon S4 SCH-I545 VRUAME7 on a P-Tel service for 3 years without problems. PTel is a re-seller on T-Mobile network so whatever coverage and services T-Mobile has - I get it via PTel (but cheaper).
The phone is rooted but ROM is old, stock version 4.2.2.
Recently something happened and started having horrible GSM reception at my work. Barely can make a call. 50% of time I get ZERO bars at all. I don't care much about data, I'm using EDGE and it's enough for me. But I do need reliable Voice.
Question 1. Does S4 SCH-I545 have all bands for voice that are used by T-Mobile?
Question 2. I've heard that S4 SCH-I545 lacks some LTE bands of T-Mobile. IS LTE USED BY T-MOBILE FOR VOICE NOW?
Question 3. Is there a way to flash ROM in my S4 SCH-I545 to "unlock" all bands necessary for full support of voice on T-Mobile network?
Thanks!

This really should be in the Q&A section.
Voice and edge data should work, but not much else. I would highly recommend you just find yourself a cheap GSM phone if you want good coverage and reliable data. You can get a Moto G or similar for like ~$120, and you would have a much better experience.
Yes, t-mo uses VoLTE but I doubt your phone picks up any LTE signal at all from T-mo
There is no way to "unlock" bands. The radios are actually different in each model of S4

[Q] International Variant of Galaxy Note 4

Hey folks I was just wondering if anyone knows if the international version of the Samsung Galaxy Note 4 is able to receive LTE data speeds? I'm on Cricket Wireless and they run off of AT&T towers.
Yes it is. I am using the international version for quite sometime & constantly utilising LTE data connection for many hours on daily basis.
