AT&T Note 3 SM-N900A on T-M network issues?

Hello everyone, based on extremely poor ATT coverage in my area comparing to T-M I plan to purchase AT&T Note 3 SM-N900A, unlock it and use with T-M SIM card.
Would I face any issues in terms of unlocking and data coverage?

Soooo.... why would you want to buy a N900A. I feel like we are missing some piece of info. What about getting the N900T and having the best of both worlds. The modem on the N900A is more restricted than the Tmobile version (surprise surprise).

Really? I'm glad I asked prior to spending the $$$
Other than the firmware the phones are identical, correct?
Right now I borrowed Note 2 AT&T SGH-I317 and it seems (to me) to work OK on T-Mobile.

Yes, the Note 2 was one of the last phones before ATT went crazy and started locking down everything. You could enable the AWS bands of tmobile on the ATT note 2. Here is a guide for the N900T if you go that route. Many of us are doing it. You can use it on either carrier. If you are going to use tmobile you might as well use the wifi calling also. It's free and only on the N900T.

Thank you! But the guide is for using T-Moblie phone on AT&T network, I have the opposite.

I know. My point is that the N900T works perfectly on ATT and Tmobile. It works on both carriers and is the most up to date. The N900T has had J7 for a week where the ATT model just is now getting J5. The carrier specific features like wifi calling are not on the N900A.
Also if you read in that thread I list the fcc bands that are active on the N900A compared to the N900T. They are more restricted than the Tmobile version.

Ok thanks again, all I need is the best deal on either used or new N900T. I don't see any listed on Amazon and pricegrabber brings up three crazy deals price of $700 with signing up with T-Mobile

Yes, you will definitely be happier especially if you are wanting to use it on the T-mobile network.

att sim in n900t? HSPA+&LTE?
Sorry for barging in just a quick question and this thread seems to be the most logical place to ask. Anyway, I have AT&T and just got the Note 3 n900a. If i got a T-Mobile version n900t and put my AT&T Sim in it if i unlock it, will i be able to use it with AT&T's data like hspa+ and LTE or will i just be limited to EDGE. Only reason i ask is because like you say AT&T is going nuts with locking everything down and Im sure its going to be a pain in the a** for the Devs to unlock the bootloader so we can (when it comes) flash custom recoveries and roms. Just like with my att galaxy s4. I was happily rooted and at the time i didnt flash a rom yet i was waiting to find one i like. (mind you i was on the MDL build) and as forgetful as i am just being stock rooted i never froze the samsung software update and it updated to MF3 build and wasnt able to fash a recovery. so i unrooted, reset flash counter and did a warranty exchange and was lucky to get one on still on the MDL build. the second i got that i rooted flashed CWM recovery and flashed a custom rom so it wouldnt update on me. I just dont want the same situation for when the devs unlock the bootloader and get a flash able recovery so just thinking maybe a tmobile note 3 with my att sim may be the way to go to avoid that. lol Not like the note 3 needs any custom rom with the beast of a phone it is but sometimes i like to switch up and use stock/aosp android.
Thanks and sorry for the paragraph here and my apologies if i asked in the wrong spot,
Dave

[Q] Unlocking AT&T Note 3 that's under contract

Is there a way to get unlock code from AT&T if the phone is still under contract.
I read that there are people who successfully got AT&T to provide unlock code while their Note 3 is still under contract.
Some say as long as your account is in good standing and they will give you the code.
Can anyone share which AT&T department/phone number I should talk to?
I have tried calling 611 a few times explaining that I had to travel out of the country for weeks and I have been with AT&T for years and never missed a payment or terminated a contract.
They kept saying they recently changed their unlock policy and referred me to the at&t unlock website to submit a request.
I prefer not to root at the moment so Chainfire's Region unlock is not an option for me.
Thanks in advance.

Normally AT&T will unlock your phone after 3 months of ownership. If root is not an option for you and you can't wait for 3 months, you can buy an unlock code from sites for $25-$30.

Verizon bought Nexus on different carrier?

Hi,
From what i've seen it sounds like Verizon no longer locks their LTE phones. So am I correct in believing that if I got a nexus 6 through verizon, I would be able to just plug in a t-mobile SIM and use it without issue?
Would wiping completely and flashing all the stock google images remove any verizon bloat/bootscreen?
THanks

My GF had a verizon upgrade she didn't care to use. So figured it would be nice to pay $350 vs $650. First time i've bought a phone off a carrier in like 4 years. Can't believe they charged a $40 upgrade fee. Tmobile FTW!

Thats not necessarily true some carriers still can sim lock until device is paid off or contract is complete.
Edit: AT&T did this

Yeah, I know from my ATT days. However as far as I can tell, I believe Verizon doesn't follow this tactic.
http://www.verizonwireless.com/aboutus/commitment/safety-security/device-unlocking-policy.html
Device Unlocking Policy
Postpay Device Unlocking Policy:
We do not lock most phones or tablets that are activated with our postpay service, either during or after the term of your service contract or Edge installment sales agreement.
We do not lock our 4G LTE devices, and no code is needed to program them for use with another carrier.

Be careful about this assumption. The Droid Turbo boot loader is still locked an there is no root, while the Droid Moto Maxx (International Turbo version is unlocked) . Most verizon phones can go from Carrier to carrier if they are a global phone so from that perspective they are not locked and can be used on other carriers but it doesn't guarantee the boot loader is unlocked and root is available.

I got a Verizon Nexus 6 activated on Sprint yesterday. They just dropped the last digit of the IMEI and it activated with no issue. No SIM lock either. Store was very reluctant to try but 1 guy there had a Nexus himself and wanted to see if it worked.

[Q] Quick Questions, Unlocking Verizon N6 for ATT

Ok so in short I have a Chance to trade my GS6 for a N6 In preparations to get on Google Fi. Problem is the N6 is on Verizon and My Carrier is ATT. Until i get the invite in I will be using it on ATT, So I have read that the all in one will unlock the phone but I have questions.
Will the Unlock work for the latest 5.0.2 Update?
If i swap the sim will it be sim locked (similar to the ATT bought N6)?
And before I hear the "Search", I have searched all over the internet for a situation similar to mine. I cant seem to get some of the answers I am looking for.
I am somewhat experienced with ADB and have been rooting and modifying since the old HTC Evo days. So Unlocking it isn't a problem, just some simple questions.

The only device that is network locked is the one attained from AT&T directly. All you have to do pop he SIM in and possibly change APN settings if it doesn't pull them from the network/SIM card.
Other than that, unlocking the bootloaders is cake and installing custom firmware is just as easy.

So the N6 came Unlocked from factory? So I don't have to do any leg work, just pop the ATT sim in and go?
Thanks for the quick response

All Nexus 6 (except AT&T version) are SIM unlocked. Just pop the AT&T SIM in.
All Nexus 6 are bootloader unlockable.

and just for the record, its is currently at 5.1.1 be sure to get it up to date.

Verizon Note 9 on AT&T

If I get a Verizon note 9 can I just pop an Att sim into it and it will work. I know there may be differences between voice and data but Basically is the Verizon NOTE9 GSM unlocked like past Galaxy phones were?
I read a Verizon forum where the Verizon rep said that the note 9 is GSM unlocked but she said AFTER it has been activated on Verizon.
To make matters more confusing she linked to a Verizon page that basically said all Verizon's post pay phones are GSM 4G unlocked (nothing about activation first).
Anyone can help me here? Thinking of getting a cheap one of eBay to use mainly overseas and ATT or wherever else.

Yes. The Verizon models are unlocked. And it's the same exact hardware as the ATT version. My recommendation is to flash either the U1 or the ATT firmware though. Otherwise you'll get the Verizon boot animation and Verizon bloatware.
The ATT firmware will allow you to use WiFi calling and VOLTE.
The unlocked U1 firmware will be clean and have no carrier bloat.

Thanks for your answer. I will have to read up more on the Flashing and U1 firmware!
I see now that on ebay that some say verizon unlocked and some say verizon locked and some of the verizons up for sale dont specify (but in the item detail it says locked or contract)... This makes things more confusing.
I have always bought verizon phones for the unlocked gsm. I did read that verizon was going to stop having them unlocked....this is my main fear.
So what you're saying, is that the verizon note 9 is 100% gsm unlocked? sorry to ask again.

I'm also looking for that definitive answer as I want to get the Verizon Note 9 for overseas use. I read that it will be unlocked after activation as they were having armed robberies at stores and other inventory locations. I was going to buy the Sprint model but it cost almost $150 to unlock.

Verizon started that with the Pixel 3, after the Note 9. The Note 9's from Verizon are unlocked. Even with the Pixel 3, once it was activated with a Verizon SIM, it was then automatically carrier unlocked. So if you buy a used VZW Note 9 from eBay, its already been activated on Verizon, so no worries.
Just be careful buying off eBay. If its still under contract and the seller stops making payments, it will be blacklisted.

They buy on Verizon because Verizon offers better deals. Then they want to use the devices on other networks. But since Note only has A firmware, not B, it's an annoying process for those who haven't flashed before.
AS to your second question: ATT doesn't allow Wi-Fi Calling nor voice over LTE on unlocked devices. So many ending putting up with their bloat in order to get those features.

It used to be easier. Verizon would often offer buy one get one free on Samsung and LG devices. You had to sign up for new service and put the phones on a payment plan. But the second phone uses to actually be free, not just bill credits. And you could pay off the first one and cancel your service.
I one time bought four Galaxy S7s when they were brand new, started four lines of service with Verizon, then paid off the phones and cancelled the service. Then I sold all four phones and netted about a thousand dollar profit off the deal.
Did the same thing with the LG G4 with Verizon when they offered $600 prepaid gift cards for each phone you bought.
Now Verizon, like all other carriers, lock you in with bill credits.

As they say, all good things must come to an end.

Verizon note 9 on AT&T
I'm using an unlocked Verizon note 9 512gb 8gb ram on AT&T and amazingly everything works. Wifi calling, video calling, volte. Even went to UbreakIfix and they installed Android 10 onto the phone. When I put the Sim card into the phone it loaded all the AT&T software on the phone and I was good. The great thing about Verizon unlocked phones are that they have the full CDMA and GSM capabilities so you can use them on any carrier. It wasn't a hassle at all to do.
