I am going to get the note but when i research on unlocking it i found the modem t unlock that makes it works with tmobile hspa+, but when i go on craigslist to to buy it they sell the note with "imei" unlock....whats the difference?...
IMEI Unlock = SIM/Network Unlock
If your phone is AT&T Network locked, you can use your phone with only AT&T sim cards.
So If phone is Network Unlocked, you can use it with any sim card.
Modem unlock will make your phone able to connect T-Mobile's Mobile Network (it unlocks the frequencies that hardware supports but not software)

There is no better or worse - if you want to use AT&T and have an AT&T SIM, then you don't need either.
If you want to use T-Mobile then you need to IMEI unlock the device so it accepts a T-Mobile SIM, then you need to install the T-Mobile Modem if you want speeds beyond 2G EDGE.
TL;DR: IMEI Unlock lets you use a non AT&T SIM in the device, Modem "Unlock" lets you use T-Mobile's 3G frequencies along with that T-Mobile SIM.
Can anyone point me to a good write up on how to install the Tmobile modem?
I am rooted and IMEI unlocked. Sorry just new to this stuff.

all i had to do (after root and unlock) was flash the "Blaze 4G modem" through Clockwork mod, from AllGamer's thread. that opened up the AWS frequencies.
EDIT: found it

so basically you need both unlocks to use it on t-mobile....imei to use t-mobie sim card and modem unlock to use 3g/4g speeds on t-mobile network....and i heard u still get a weak signal .....dont know if affects your experience as in dropped calls and slow data ect ect...but um @ schuflea http://rootgalaxynote.com it will tell you how to install anything on your galaxy note...good luck ..
if any one is still thinking about getting a gnote.....you should wait...its officially coming out for t-mobile....well thats wuts going around the net....theres even pictures of it with t-mobile branding.....you should wait like a month...its 4/28/12 wait till 5/28/12 lol....see wut happens....
I've seen threads where modems are used to get the phone on different networks given the right apn. Does this side step a carrier lock or is it assumed these phones are already unlocked?
You can flash a carrier locked phone with any modem you please. You can also change the APN settings on a locked phone. What you can't do is use another carrier's sim card.
So no, this doesn't side step that. You will need to unlock.
International Note N7000 is factory unlocked.
All carrier versions SGH-i717# are all factory locked.
It costs from $7.00 to $25.00 to carrier unlock.
Ok makes sense. What happens if you start using a tmobile modem and apn with att sim? Would att just charge you roaming or something?
Your sim would connect your phone to the t-mobile network using the frequenies of at&t. You would have EDGE data speed (2g), voice, mms.
hi, Could some one explain me what does LTE unlocked sim free phone mean. Is it something like an unlocked phone? Can i use a Gsm sim in this?
Yes, you can use a GSM SIM in it. It's unlcocked.
Read it this way:
LTE, unlocked, sim free phone ...
LTE -- capable of using the fastest wireless data network, and it also supports the slower networks (like GSM)
unlocked -- it is not forces to use a particular carrier, like Rogers or AT&T
sim free -- the phone does not come with a sim card (that is for a particular carrier) and you have to purchase one to use the phone, the AT&T phones come with an AT&T sim
Based on what I read so far, only unlocked version of AT&T will work only with GSM provider. Would like confirmation of this. Thanks!

Uh... If it's an unlocked phone there is no reason it wont.

Optimumind... can you provide any explanation for your answer?
Unless something has changed, Sprint is CDMA, not GSM.

An unlocked AT&T GS8 will work on other GSM networks but not on Sprint b/c Sprint won't add the AT&T GS8 IMEI to their system.

The hardware on all the s8's are the same so technically it will work but the imei isn't white listed so you won't be able to activate it on sprint but the sprint version can be activated on att or any other gsm provider.
Sprint galaxy s8 works with tmobile and verizon

Hey there. I have an S7 Edge unlock from t-mobile running the unlock firmware from G935U. Sprint SIM cards are lock, I have a friend who works for sprint. I have 3 Sprint S8 and S8+, 2 unlock and running on T-Mobile network. I took 1 of the SIM card and put in my Unlock S7 Edge, the phone just keep trying to connect to network and repeating the same process. Didn't work at all, but the Sprint S8's works excellent on T-Mobile network after flashing the UNLOCK firmware.

I got 111.71 mbps download, 20 mbps upload speed from my Unlock Sprint S8+ running G955U1 unlock firmware on T-Mobile network. Couldn't ask for anything more than that.
I will provide my non Sprint S8 variant experience.....for any US S8, they all have the same hardware. I have noticed that ATT and TMO models have CDMA hardware, but are turned off in the carriers version of the firmware . Flashing the stock unlocked S8 firmware or the Sprint/VZW FW will enable the phones for use with CDMA and all LTE bands. I had an ATT version sim unlocked and attempted this on Verizon FW with a VZW sim and it worked perfect....but there is a major roadblock with Sprint. Sprint is the only carrier that I have tried that requires an update of the IMEI to the account (ie you cant just pop a sim in and the device works). VZW for example shows Unknown device on the account instead of an S8, but all the services still work. Sprint shows 3G for about 5 minutes, then you get a message that the sim is locked and to reboot or call support (not the same as the phones sim slot being locked, but more that the system cant register the sim/device combo). Sprint stores have the capability of adding IMEI's to the Sprint database, as long as the IMEI does not come back as ineligible. Well, I took the S8 to several stores and none of them could add it to the system. Several employees advised me that the IMEI's from other carrier's are blacklisted so that it can not be added and the only ones that the system would allow to add are IMEI's that were sold as unlocked or Sprint branded. If the IMEI can be white listed, then I am certain it would work.

Yup, Sprint sucks very well in this regard.

This phones are listed among eligible phones for Sprint's BYOD 1 year free plan. Does it say something?
Samsung Galaxy S8 (Verizon, AT&T and T-Mobile)
Samsung Galaxy S8+ (Verizon, AT&T and T-Mobile)
Yes it will work, i put a freedom pop sim in, and it restarted with at&t logo

I had a similar experience with an Unlocked Galaxy S7 and Sprint. I actually had to get Samsung Tech support on a conference call with a Sprint Manager, because Sprint told my customer the the phone is incompatible with the Sprint network. After embarrassing the Sprint rep, he white listed the IMEI number on Sprint's network and the phone worked.
Also, MetroPCS has the same policy. You cannot just pop in a Metro Sim card. You have to call them and register the IMEI number. After about an hour tops, the phone will complete provisioning and be able to work on Metro's T-Mobile network.
T-Mobile is instant. You cab pop a T-Mobile Sim card into any sim unlocked variant and it will work. However you will need to go into settings and follow the T-Mobile instructions on how to set up the radio frequencies. The better way is to just flash the carrier's ROM version onto the phone. This way you will get the features and updates from the carrier. Carriers seem to get the Android updates faster than Samsung. A trade off for bloatware.

Maybe I should try this approach with my Galaxy S9+ (AT&T, unlocked).
Sprint is a PITA.

You may have been referring to me regarding the unlocked Galaxy S7 & Sprint. Many thanks for that one. I'm going through the same crap now with Universal unlocked IPhone 7. Sprint is a PITA!
I can confirm the SM-G955U from AT&T does work. I confirmed this via Sprint site. Just Google Sprint byod eligibility and you'll find the link.
My biggest roadblock was AT&T had a network lock on my phone so the sim Sprint sent couldn't be used. I then used the services provided by gsmzambia to network unlock the device. It's currently working on Sprint network.
Pros/Cons?
Pro: No AT&T preinstalled bloat
I'm using an Essential PH-1 unlocked with AT&T. No problems.
Used a Mate 9 unlocked on ATT with no problem. Most US unlocked phones should work without any problems on ATT
VoLTE or HD calling as AT&T calls it might work on an unlocked phone if they will provision your line for the service. They did it for my Pixel 2 and it worked after I got a new sim. I don't think wifi calling will work on any phone except an AT&T device. I would make good use of this service so I'm opting for the AT&T version. If I find wifi calling works on an unlocked model I may switch but I don't think it will. We do some vacationing at a place with wifi but no cell service. My wife's AT&T iphone has it and it's pretty cool.
If the unlocked version is snapdragon then it will work just fine and lock to USA AT&T. With the S8 phones they were unlocked until you put a SIM in it and then it locks to that carrier. I'm curious is the unlocked version the exynos or the Snapdragon?

Having issues with SM-G965F on AT&T LTE
I just activated my SM-G965F and I'm only getting 3G and 3.5G (H+). No LTE. If I change the mobile networks settings to nxtgenphone, it connects to LTE, then drops and I get no data. I can only use the 'phone' version. My AT&T account has a grayed out device for my account. Checking compatibility with the IMEI checker for AT&T says it cannot determine if it is compatible. the 2nd SIM slot IMEI number is considered invalid!
Heading to the AT&T store at the mall later... not expecting much help.
I have the Note 8 and it was a PITA to get it full working on AT&T. Only thing that interest me was the Volte for talking on the phone and data at the same time, never got it working 100%. Had AT&T provision with new chip still not working good, so I sold the unlocked and got an AT&T model and had it unlocked and all is working well.

It was not the APN settings, entirely. It was that myAT&T would not recognize my IMEI number as a 9+. So, working with a store clerk at the local mall, she suggested to punch in a fake(last number altered) IMEI number using the in-store SM-G965U models. Since this has nothing to do with actually logging in or SIM verification, it worked. The SIM does its job and my account has an S9 (not a plus) on it, so when I changed to the 'nxtgenphone' APN settings, it is 'allowed' to log in (that's my best guess, anyway).
There is no other reason why the SM-G965F would NOT work on AT&T LTE since it has 3 of the 4 LTE bands (band30 is not included, but is only used in new, dense environments to alleviate network congestion -- my understanding).

So if I buy and ship an unlocked Galaxy S9 from Samsung website, it will have Snapdragon and not Exynos? I'm in a US territory.
I'm getting a good deal off their website with accessories and whatnot buying unlocked but I prefer Exynos
I'd rather not post and make a new thread. If someone else can confirm, I'd be much obliged
Yep it does. Just make sure it's on Snapdragon.
