Not the Verizon version (SM-N910V) does not have band 7 LTE, but there are other versions of the phone that do include LTE band 7.

Enable CA

hello,
I have Tmobile Galaxy Note 3 and would like to know if there is a way to enable carrier aggregation?
I really need this feature because I am headed to South Korea and Australia for 3 months on my research business trip. All carriers in those countries use Carrier Aggregation and in order to have service, I would need a device with carrier aggregation. I don't want to purchase another phone cause my phone is working fine.
Also, I have checked with the major carriers in those use bands compatible with my phone. I also know that Note 3 has snapdragon 800 3rd generation gobi LTE modem that supports this. So is there a way to enable that feature?

Anyone?

There is a way. I have a T-Mobile Note 3 and I've done it, though T-Mobile doesn't use CA yet, so I have no way to test it. Also, just so you know, Carrier Aggregation cannot combine any 2 LTE frequencies; it's specific pairs, like Band 2 and Band 17.
Anyways, my instructions are here: http://forum.xda-developers.com/showpost.php?p=57178013&postcount=80

Thank you so much! I will look into it. T-Mobile does have carrier aggregation in Dallas, TX and Atlanta,GA, binding band 2 and band 4.

Just a minor change btw, you have to choose REL 10 if you didn't. It's actually not optional. Let me know if it works, because there's no CA here in NYC
The way to check if it's working is if you dial the same dialer code after that and go to Basic Information -> As Information.
If you see "CA Enabled but Not Configured", it means it's turned on on the phone, but not the towers you're connected to. If you see "CA Setting Wrong", do the steps over and turn on LTE REL 10. Otherwise, if it's on and working, you should see two frequencies listed. There are pictures on the next page in that thread showing what it looks like.

Awesome I edited my above post to add more info on how to make sure it's working.
Can you post a screenshot of the AS Information screen just to make sure?

It's not letting me attach the screenshot because I am a new user and need to be a member for at least a week. Optus 4G Australia is my carrier currently.
But it says:
CA enabled and configured.
Band 17 (5mhz)
Band 3 (15mhz)
R0 RSRP Band 3: -76, RSRQ: -4
R0 RSRP: -87, RSRQ: -7
EUpS: 4
AtReCo: 3, TaAtCo: 0 DeAtCo: 1.4rev99
Speedtest: 132mbps down and 39mbps up. Thanks again.

Holy crap! It works! That's awesome! That's Band 1800 (Band 3) and Band 700 MHz (Band 17). Sorry, I just have one last question (I promise). This is 100% the SM-900T (T-Mobile US model?). What modem/baseband (Settings -> About Phone)?

Baseband is N900TUVUNENK3 running Android 4.4.2. I haven't rooted either.

Verizon Band 4

Any reason why my Pixel 2 XL will not connect to Verizon's Band 4? I get all of the other bands, but not Band 4.

How are you determining which band your on?
Not trying to be sarcastic, I am truly curious. I too am on Big Red, but couldn't tell you what band I'm on

@Badger50: Answer to your question is at https://play.google.com/store/apps/details?id=net.simplyadvanced.ltediscovery&hl=en_US
@BuffLG: Verizon's band 4 may be widespread but it is used to provide added capacity to the network. If the cellular traffic in your location isn't heavy enough, you may never see band 4 even though the P2XL supports it.

I use Signal check to see the bands. Or LTE Discovery.

Much obliged kind sir. I do know/remember that I'm usually on band 13, but was curious to know how to check it. Thanks again :good::good:

Lol with LTE Discovery it says I'm on ATT band 12, while signal check shows band 17.

Signal Check Pro easiest way.
Band 13 is Verizon's original LTE band has furthest range (700 mhz spectrum). Band 4 (1700 mhz) and 2 (1900 mhz) are their AWS spectrum.
Band 2 also has the highest capacity. Usually deployed in the most congested areas first.
Band 2 will technically be the fastest. Will probably be the hardest to connect to, but if you're close enough to a tower and getting Band 2 service, you're golden. I've seen speeds close to 100 MBPS on Band 2

I'd bet a nickel you're not seeing band 4 because of this bug: https://issuetracker.google.com/issues/37136986

Reading through everything, most people are having issues with T-Mobiles LTE band 66 showing up as band 3.

This bug is relevant on Verizon, AT&T and T-Mobile but not Sprint (I believe) as they don't have Band 4 and/or 66. T-Mobile turned on MFBI at least several months (maybe a year?) before Verizon and AT&T did.
Again I don't know for sure if it's related to what you're seeing but it does "smell" that way. Band 4 in the Phoenix area almost always shows up as a Band 2 EARFCN that Verizon doesn't own when using Signal Check Pro as it is being reported incorrectly by Android. The EARFCN is correct under the same conditions using Network Signal Guru since it reads directly from the Qualcomm chip.

I always got band 4 until the last couple weeks .. I now get Band 3 instead of band 4 which seems to be faster if I get a strong enough signal.. Band 3 doesn't seem to be as strong a signal as Band 4 though.. Band 4 was always displaying as XLTE where Band 3 displays as LTE.. my old Moto Pure still gets Band 4 so I really don't understand why the Pixel no longer will get it! Got to be by design by Verizon, me thinks!!

That's the exact issue @turboencab is talking about. There is no Band 3 LTE in the USA. You are seeing Band 3 because of an Android OS/Qualcomm bug that cuts off EARFCN values above 65536. Band 4 can be "displayed" as Band 66 and most operators choose to do this now. Band 66 EARFCN values are above 65536.
Tldr; there is no Band 3 in the US. You are still connected to Band 4. Apps aren't able to display the correct band due to an OS bug.
Try to use CellMapper as a tool to see what you're connected to. The devs for that app can "correct" this issue based off some assumptions. https://play.google.com/store/apps/details?id=cellmapper.net.cellmapper

Network Band Frequency

HI,
I operate a Note Pro 5 in the UK on the plusnet network which uses the following bands / frequency's. I use the global ROM
800MHz band, the 1800MHz band, the 2100MHz band
Iam not having much luck with the 4G speed / connection. Iam wondering if that's because the handset does not work with these bands. No point reformatting my phone only to find out if the phone does not work with these bands !!!
Thanks
Mathew

It should work fine, as they use EEs network. I use virgin mobile that also uses EEs network and its fine. Have you tried amending the APN settings?

Yes you are correct Virgin and Plusnet both run off EE but its not that simple.
EE only allow some bands to be avalible for resale the ones I have listed are what Plusnet use.
You have pointed out something I should have done!!!! I have removed the APN and started from scratch I will try this for a few days and see what happens.

So from what I've read plusnet don't seem to offer the 800mhz frequency (EE/virgin do), but if your Redmi Note 5 is the global version it will work with all UK 4G bands (including 800 or band 20 if its available from your provider). Usually band 20/800mhz travels further and so tends to be used more in rural areas to help improve coverage. Were you connecting to 4g OK before or have you just changed to plusnet or just got your RN5?

Yes I thought that but have had conformation directly from Plusnet that they do use the 800mhz range

@MathewRB
Global version of Redmi Note 5 supports all frequences You mentioned. The only problem is that it doesn"t support carrier agregation (LTE+) which can lead to slow data acces when the transmitter which Your"s phone is connected to is clogged

Thats a good bit of information looks like Iam finding more and more of reason (excuse) to upgrade to the 7 Note Pro. But when is the 8Note Pro due to come out any idea?

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.
