Anyone running a T-Mobile note 4 on at&t?

Considering selling my at&t note 4 when my pre-order is filled and buying a T-Mobile version to use on at&t.
Any reception issues?

No issues for me at all. Get great service everywhere, including lte

I was planning on doing so, but I noticed the T-Mobile variant is missing of the LTE Bands that the AT&T one has. Not sure if that will create any problems down the road. Any thoughts on if that matters?

ATT is not using those 2 bands in the US. (20 and 29 lte) It might be for international use in which case I'd rather have the tmobile ones. Anyway, according to Wikipedia they don't even own spectrum in one of those bands so deployment is years off even if they decide to do it. Plus the note 4 would have to go through the FCC again because it wasn't approved to run on those bands in the USA. Those extra bands are not anything to be worried about.
EDIT: Ok, I found some more info. There are no deployments of band 29 in the US yet. Band 29 is downlink only and is used with band 4. This will be AT&T's LTE advanced setup.

Thanks for the info! Time to go to TMobile and get me an unlocked Note 4.. Will they unlock them for you right in the store or no?

Ya, been reading up on it. I still think it will be a while before it gets deployed and probably if you're not in a big city you'll have to wait longer like the wait for LTE.

No you need to use cellunlocker.net or a similar service.

Thanks for everyone's help. I'm trying to find this information on the Internet, but some of it is like Greek to me.
What bands does att use in US?
What bands does the T-Mobile note 4 handle?
What bands will not be possible on the T-Mobile note 4? Bands 20+29?
Sorry for the questions, just trying to learn and you guys seem like you know your stuff.

ATT Uses:
GSM: 850, 1900 Mhz
HSPA/UMTS: 850, 1900 MHz
LTE: Band 4, 17 (29 for LTE-Advanced)
Tmobile uses:
GSM: 850, 1900 Mhz
HSPA/UMTS: 1700, 1900 Mhz
LTE: Band 4, 12
Tmobile Note 4 Supports:
GSM: 850, 900, 1800, 1900
UMTS: Band 1 (2100), Band 2 (1900), Band 4 (1700), Band 5 (850)
LTE: Band 4 (1700), Band 12 (700a), Band 1 (2100), Band 2 (1900), Band 3 (1800), Band 5 (850), Band 7 (2600), Band 8 (900), Band 17 (700bc)
Tmobile Note 4 does not support band 29 but imo it's a small price to pay for an unlocked bootloader. Plus, there are no deployments of ATT's LTE-Advanced network (Band 29/4) in the US yet and depending on where you live it could take years to reach you.

This is super helpful.
So let me ask you, when you say the T-Mobile version is missing the advanced lte bands (20&29), does that mean the phone will only miss the benefit of the next gen lte speeds?
So for example, 20&29 go live in my area, I have the tmo version, I'll still have lte just not super/advanced lte?
Thank you again for your time and expertise!

Ok first thing, band 29 is download only so it is used in conjunction with band 4. Band 20 is for who knows what but I haven't seen any news about ATT's plans for that band. It's not a part of ATT's LTE Advanced plans as far as I can tell. It may be there for international support only.
Yes you are right that you will continue to get LTE just not LTE advanced, and that might be a year or most likely longer before it reaches you. Think of the timeline for ATT's LTE rollout. I researched a bit today and found that Chicago supposedly has the first actual deployment.
Also, ATT has said they are not doing their deployment of LTE Advanced to increase user speed. It is just for network capacity. So you might not see speed increases at all according to ATT's presentation at Mobile World Congress. Tmobile is in a better position capacity wise because it owns more AWS spectrum (higher frequency = faster data). They are deploying wideband LTE.

Unlock service
Can any of you with a T-Mobile device on a different network tell me what service you used to unlock your phone? I saw a mention of cellunlocker.net on one thread, but it says on their site it could take up to 15 days to get the unlock for the T-Mobile Note 4. Is this typical? I've never used one of these services, so I don't know what the better routes are. Thanks!

Att lte advanced has been deployed in NYC since the iPhone 6. It's fast but tmobile is faster I think.

How is network performance using the TMO version on AT&T? Last year with the Note 3, I had such horrible LTE reception I took it back. T-Mobile devices are not optimized for band 17 support. It comes down to: you want a phone that gets a great signal, or you want a phone you can root/rom.

From what I have seen everything should be working fine. If you live in a city that has LTEa you will miss or on improved performance with band 29, but that should not effect most people.

Cellunlocker.net wants $30. Anyone of a cheaper place that is just as reliable?

Would a blocked tmobile note 4 with regional unlock work on att ?

Hi All
Just to add my 2 cents...
I went from a At&T Note3 to TMO Note4
Just put my Note 3 Sim into the Note 4 and am up and running for about a week now...
When I log in to my ATT online account it still shows The Note 3 though but as I said all is well for now.

[Q] ZE551ML at&t APN settings

I am not getting 4G LTE. It is staying on H (hspa). I have the one plus one and get LTE.
The info online says this phone should have all of the bands required.
Any ideas.
Thank you

Check Settings - Mobile Network settings - Preferred Network Type and set it to LTE if you have this option and is not already set.
But I doubt that this is your problem. You bought the Taiwanese phone, didn't you? While OnePlus supports all ATT LTE bands (17, 4, 2), the Taiwanese Zenfone 2 doesn't support band 17 (nor ww model), which is otherwise typical for less inhabited aeries in the USA, but it seems that is widely used by ATT. Try the phone in the downtown or another city and you'll probably catch the LTE on other frequencies.

Yes I purchased it from Taiwan but all of the sites show so many bands for this phone. Asus does a terrible job with their model numbers. There are so many different versions with the same model number. There is a 4 g setting not lte and that is selected. I did pick up 4g while driving through part of the city.
Is there going to be a US model?
Thank you

Yes. There is a US model and its supposed to be released in the next month or so. The link below, click on specs, shows the LTE bands for each region. Clearly shows the Taiwanese model not having the 17 band.

That stinks. I took that page as it will work in all of these markets. Oh well

Where in US are you?

There are some areas in the US that are only on LTE band 17. I suspect that's OP's issue.

I looked at it and TW, WW and US all have 1700 bands if that's what you are referring to. If not can you shed some light?

The topic is about bands not frequencies. There is nothing such as 1700 LTE band. Actually both USA and TW phones work on approximate LTE 700 MHz but bands are different because uplink and downlink are different. So TW model works on band 28 and US one on 17.

I see now. Tnx for the quick response. Hopefully I'm not outta luck when the phone arrives tomorrow from TW. Do you think that flashing later on a radio or baseband will solve this issue?

It's not that simple. Luckily Intel chip supports all LTE bands. But they must be activated in kernel too. Maybe someone will find the method to activate the missed ones. Otherwise you are not so bad. With TW phone you are short of only one LTE band of four major in the USA, Europeans missed 2 of 3.

Frequency wise is matches everything AT&T needs, i just picked up my 4g/64gb TW model, i'll be playing with apn's to see if i can get lte to pop. Only getting H+ so far.
Correction, shipped with WW firmware, no 700mhz for us.

More - As posted above, this Taiwanese version is missing the LTE band 17. And there are some areas that this may be the only band available, so you will not have LTE in those situations.

Thanks so much.... I was having a heck of time here with my Zenfone 2 in Tucson AZ on T-mobile.... I was stuck on 2G... but updating the APN to fast.t-mobile.com and 2 reboots seems to have done the trick. So glad I don't have to EBAY this! THANKS AGAIN.... Loving this thing so far!

Well ****! This is where I am stuck win H+ on ATT.
No way around this huh unless someone does a new rom? Or is it hardwired?

Any way of discovering if the Zenfone 2 has band 12 capabilities?

There are a small amount of phones that have band 12 support through updates. Their respective specifications usually don't include band 12 support, though looking around states band 12 support can be enabled via an update.
way t
Currently, the zenfone 2 states no band 12 support. Is there any way of looking into the phone itself to see if it has band 12 capabilities? Crossing my fingers for this, as this phone is super slick and powerful for an awesome price, and as a T-mobile user, lack of band 12 support is the only thing holding this phone back from purchase. most current band 12 capable phones are either lackluster in features, or too expensive.

Hey! Are you in an area that doesn't support T-Mobile 1700/2100 MHz AWS (band 4)?
I think i read somewhere on the tmobile forum, they use main band 4 and 2 being implemented.
Zenfone 2 supports both, I just got mine US version today and the LTE is working for me.

Please see the ZenFone 2 support band list - http://www.asus.com/us/support/FAQ/1011352/

i live and travel between stockton, CA; Sacramento, CA; and Tracy, CA. signal is OK for the most part, though in some areas it leaves a bit to be desired. Currently using a Nexus 5. Through the LTE discovery app I know my phone typically picks up band 4. not sure about band 2. There are some indoor areas like buildings that aren't all that great on tmobile in my area. my local best buy for instance instantly drops to low signal the second i step in the store, even though right outside is full bars. driving along the freeway in certain areas deem little to now signal sometimes as well.
I'm not here to complain about my tmobile service. Just trying to ensure future proofing of my phone purchase hoping that band 12 would improve those situations.

If your a legitimate Asus rep, then that is a bummer the lack of band 12 support. I've already been to those pages and checked again. I just wanted to see if band 12 was possibly hidden somehow, as it seemed to be the case with a 2-3 other handsets since theyre only activated via software updates.
Thanks for the replying.

I am confused, it looks like the USA version does do Band 12
see below bolded:
USA T-MOBILE FREQUENCY: BAND 2 (1900MHZ), BAND 4 (1700/2100 MHZ), BAND 12 (700 MHZ)

Nah man, he/she is just stating those are the frequencies T-Mobile operate on, not frequencies of Zenfone 2 itself. See the link right above it for the zenfone 2 supported band list.
That would be nice though. I've already read several sites stating that it does not support band 12. The point of my post was to find out if there was any way to find out on the device itself (via owners of a Zenfone 2) to see if it was somehow hidden in there. Specs for the Galaxy Avant, Xperia X3, and the ZTE Zmax I don't think initially listed band 12 support in their specs, but now supposedly they will have it enabled via their respective software updates. I was crossing my fingers hoping a similar thing would happen with the Zenfone 2.

Clearly the phone itself supports the 700 freq (Band 17) which is also where Band 12 operates. Does that require a hardware change? I dunno.
http://www.tmonews.com/2015/03/t-mobile-could-gain-from-atts-band-17-and-band-12-lte-network-interoperating/

US variant of ZE551ML does support Band 12. The LTE Discovery app revealed I was on Band 12 while using the T-Mobile service in Rancho Cucamonga, California. Going east from there, I was on Band 4 or 2, but then again, T-Mobile's rollout is just starting in Southern California.

That's really interesting Armchair. Band 12 is NOT listed anywhere in Asus' specs. I wonder if the latest OTA update kicked it in? Do you know what firmware you're running? B12 support is the only thing holding me back from the Zfone.

When I bought the phone from Amazon on June 25, 2015, Band 12 was listed in the US spec. Otherwise I would not have bought it at all because I wanted that availability. Now that I go back to the Amazon product page to get a screenshot, I see the entry has been altered to remove Band 12. However, today I'll make a trip to Rancho Cucamonga (not far from me, really), and screenshot the LTE Discovery screen when it shows the phone connecting to Band 12. (Pics or GTFO, right? )
Box Codes:
ZE551ML, BLACK, LTE,D
INTEL MRF Z3580(2.3Ghz),4G,64GB EMMC
ANDROID US,5.5" 5M/13M,N/A
Other notes of reference: When the phone arrived, the firmware was WW 2.18.40.12. I OTA updated to 2.19.40.18 then rooted (using Method 3) and unlocked the bootloader. Did not remove any system apps nor install any custom recovery. I have OTA updated twice since then, keeping root and unlocked bootloader. Currently at WW 2.19.40.22, under which I can connect to Band 12 towers. Did not tinker with the telephony settings or make any other unauthorized changes other than rooting and unlocking the bootloader.

So Asus snuck in support for Band 12 in a firmware update? Very nice Asus. Very nice indeed.

Screenshot taken near the intersection of Foothill Blvd & I-15 in California. LTE Discovery app showing connected to T-Mobile on a Band 12 tower using the ZenFone 2 (ASUS_Z00AD).

I've asked both TMO & Asus for confirmation. TMO basically said since it's not "native" it's not something they can confirm as working or not. Asus has yet to respond to my query period.
UPDATE: Got a reply from Asus. AsusUSA support on Twitter said they are unable to find any substantial data to verify Band 12 support for TMO.

UPDATE -- Official reply from ASUS

Thank you for contacting ASUS Customer Loyalty. Currently there is no support for this band and no confirmation if it will be added in the future.
I believe it is limited in the hardware. Unfortunately it's not supported.​
So looks no Zenfone 2 for me any time soon. What an OTA unsupported update can give, it can also take away.

Are you still able to connect on band 12 with newer firmware? I haven't seen a single one yet and have definitely been in known-deployed areas.

On .90 I was able to connect to B12 in the same spot as before as well as other locations around Rancho Cucamonga but I didn't take a screenshot of the LTE Discovery app for proof as a few threads here and in other forums have made it clear that T-Mobile will not support B12 on non-branded (read: noncustomized firmware) phones. Since then, the display has developed the infamous lines and fading issues as recorded by others and I have RMA'd the phone. Using a branded burner phone until all is resolved.

Damn looks like the issue is lack of support for volte.

How to use Sprint note 4 on LTE bands 3 and 7?

Hello!
I have an unlocked sprint note 4 which I use outside the USA as a GSM phone with a sim card.
So far so good.
The problem is that this phone being produced for sprint does not connect on 4G.
I have been reading about the possibility to change the NV values to be able to add LTE bands to the phone and I was able to change those values but still no luck.
In my country, the 4g network works mostly on bands 3 and 7 (1800 and 2600).
I am starting to think that probably the sprint version might have differences in hardware with other 4G capable phones.
Can anybody tell if there are any hardware differences between the sprint note 4 and other note 4 models.
Do you think that the sprint note 4 has what its needed to connect on 4G on the above frequencies?
If yes, what might be the right approach to try to resolve this.
Thank you for reading and since this is my first post on XDA please help me!

Yes, because of Sprint Spark it only uses 26 and 41 bands, 1900mhz and 2.5ghz respectively. FDD-LTE and TD-LTE are unique to Sprint and they are big enough to have the phones shipped this way. For flexability yoh should move to a GSM model phone.

Heh, what you think about this thread.
Especially about the history of success adding LTE bands 4/14 in SGS5 SM-G900P from Sprint?
Samsung SM-G900F - added LTE band 4. Confirmed operation on new band
Samsung SM-G900P - added LTE band 4/14
Samsung SM-G906L - added LTE band 4

Its worth giving a try for sure. You do run the risk of bricking your NV and losing signal altogether. However, I have done this successfully using DFS CDMA Tools on an old Samsumg Cappy from AT&T back in the day. *Disclaimer: proceed at your own risk*

After further review, and some trial and error, the above listed mod only works with GSM phones. Your Note is a CDMA version. Please do not try.

I understand but since my note is a CDMA how can you explain that it works fine for GSM and data in 3g ?
What might be the hardware difference with the international version that does not allow my phone to work in 4g in my network?
I am assuming that they use the same chip-set and the problem is only soft based.

Question Force enable carrier aggregation outside us.

Hi everyone. Im wondering if this is possible for pixel 6 pro. Basically my unit is direct from us store which is G8VOU. Now im using it in Malaysia and 4g lte works fine.
Now im wondering if carrier aggregation is possible through root. Right now from what see through netmonster it can do 2ca on the same band(check screenshot). I think its aggregating two towers with the same band, i may be wrong though.
Anyone had any idea how to force enable multi band ca? The local sold phone can go up to 5ca which are mainly band 1, 3, 7 ,8. Thanks in advance.

I would also like to know

Is it not 4G+ an indication of currently using carrier aggregation?
Try to download NPerf app and click on speed test button. It will detect your carrier and mention it's currently on 4G+ or LTE-A
Another proof is below when you check in *#*#4636#*#* . Currently my Yoodo is on band 7 and band 3.

And Digi Malaysia only have 1 band which is Band 7
Digi - Malaysia - Wireless Frequency Bands and Device Compatibility
Digi (Malaysia) uses 2 GSM bands, 1 UMTS band, and 1 LTE band. Find out if your unlocked phone or mobile device will work with Digi (Malaysia)

Yes like is said. Mine is at 2ca indicated that im at TWO bands aggregated. Which is way below whats possible. Let me know if you have something that can help instead of just pointing out facts i already stated in the first post. Thanks.

I sometimes have band 3 and 8 as well. Just never 3 or 4ca at a time. Only up to 2ca max.

The modem decides aggregation.
