I don't see much past 2G use in your country at the moment

Here in central NC I am getting around 5 Mbps download and around 1 Mbps upload. This is just from my home, I haven't taken the phone anywhere else yet. I hope to get a couple of test from other areas around my town today.

Unfortunately no, its a hardware issue. Unless the radio could be modified. The only current band that is disabled but can be opened is band 12, but that is not going to help in your country. Sorry

The Indian LTE is on band 40 across providers. LTE band 3 is also auctioned by government nut service yet to be started on that. Its a hardware radio issue and not something that will get corrected with software OTA.
Its limited to 3g use. I too have the US amazon version and its not possible to use it on 4G.

HELP, unable to call without the use of Jio4gvoice app.

Volte icon is not appearing in status bar while it's been enabled in settings. I don't know what's the issue but I'm not able to call with normal dialer. Please can anyone help me solve this issue..
I have oneplus 3T US version, 4.0.2,rooted

Please, Is there anyone that can help me..?

Haven't heard about this kind of issue yet.
Maybe u need to change apn to get it to work
There are two kind of apn, jionet and one wap something like that. Try both.
U can find apn details of the apn on Google.
---------- Post added at 07:39 AM ---------- Previous post was at 07:39 AM ----------
Or u can try clean flashing 4.0.2 and see if it works

The ROm SHould Be VOLTE Supported Then only you can use the callling Feature in Jio however my Moto G4+ Is Running Full stock and has volte the voice call was working fine without any app but from last few weeks the calling is not working i think i am not sure since i upgraded to android 7

As you said your phone is from us so maybe it's problem related to LTE band as LTE band in US is different than Indian bands. I have oneplus 3t with jio sim and volte working perfectly fine.

The problem is US Model. Check the bands. As far as I remember US model has different band not supported by Jio. You need to use the Jio Dialer for calling.

I don't think the US version of Oneplus 3T supports VoLTE on Indian bands. Airtel in India uses 2300mHz (FDD Band 30) for 4G services while Jio uses 3 bands, namely - FDD Band 3, FDD Band 5 and TDD band 40. The American variant of Oneplus 3T does not support FDD band 3, which is probably what Jio is using for calling over LTE in India and hence you can not place the call.
EDIT : This is a hardware limitation and I do not think this can be fixed by tinkering around with the software

mi max 2 4g on Att?

believe it or not, i recently was able to get 4G on ATT Network.
i am with Rogers Canada , i always have 4 g there, when in the States i use Cricket, and when in a bigger City i am getting 4g as well....So happy, didn't work before with Xiaomi mi max 1

That must be band 5 working for you! Good to hear.

please let me know- if you dont see 4g, do a manual network search and pick ATT 4g....that did the trick for me....

I don't have the Mi Max 2, but the Zenfone 3 Ultra which has similar bands. I lack all the LTE Bands except for Band 5. I can confirm that in all major cities I have been to I get LTE through band 5. Heck, even in my city which is only about 300,000 strong I get 4G/LTE in half of it. Seems like AT&T is really ramping up their band 5 LTE service.

Thanks for sharing the info. I looked up your phone and if you have the global version it appears you have more LTE bands available than the Mi Max 2. Namely bands 2,4 and 17. While ATT does provide LTE for band 5 I won't get my hopes too much for LTE. As long as I can get strong HSPA+ that's enough for my needs

I think you were looking up the specs of the Zenfone 3 Deluxe, not the Ultra. There is no version of the Ultra that has bands 2,4, and 17. Trust me I'd buy it if they did.

Finally got some time to set it up. I can confirm 4G (HSPA+) in South Jersey. Hopefully, I can go to philly this weekend to test for LTE connectivity.

Does it say 4G or H+ as the indicator? If it says 4G then you are getting LTE already. The international phones say 4G and the american phones say LTE.

For me, it says H+. However, I haven't had a chance to go to the city yet. I would say though that my nexus 6p gets LTE in the primary area I use it in but when I switch the sim card into the mi max 2 it only gets H+ in this area.

right now i am travelling on I -94 Wisconsin- Minnesota- North Dakota, and most of the time my indicator tells me 4g....

Sorry to bump an old thread but I was in Texas last week and I picked up 4G in San Antonio.
Also back in Illinois I am picking up 4G here. This started after the last phone update.

Yeah Band 5 is nicely saturated where I live so I can't complain

Xiaomi Mi A2 Carrier Aggregation

Hi. Could somebody test if this smartphone does intra-band and inter-band carrier aggregation with B1, B3, B7 and B20 bands?
Thank you in advance.

It does with B3/B1, B3/B20 and B3/B8 as far as I could test

I tested this on T-Mobile NL and KPN NL. At my work, I receive a B3+B1 Transmitter and it shows CA which is a sign for me that the phone support this combination. At my home, the local transmitter has B3+B8 or B8+B3 depending on how weak the reception is and I still see CA on this phone. On KPN NL, I have at various places CA from which I know this is B3+B20 or B20+B3, when B3 is weak.
Since this phone has the Snapdragon X12 modem, which I also had in my former HTC 10 which was rooted and I had a diagnostic tool for Qualcomm on it, I am pretty sure it has the same support of CA bands. as I see CA on the same places as before with the known combinations.

Thanks, what shows CA? Are you using Network Signal Guru?

4g+ connection disabled on Mi A2

Hi all,
someone know why xiaomi don't enable 4G+ on Mi A2? the SD660 is capable of it
maybe xiaomi should pay for using 4G+ license cost on Mi A2?
I've submitted a request, please confirm it here

I have 4G+ so nothing to complain here.

I have 4G+ too.

I'm in Italy and I do not have 4g +, is there a way to unlock it?

I was in Italy a few weeks ago and had 4G+ in the Milan region. So it also works in Italy.

same problem with orange slovakia operator. no 4g+ with carrier aggregation on 2600 + 800 MHz (CA bands 7 + 20)

The Mi A2 supports 4G+ ( LTE-A or Carrier Aggregation ) out of the box, it just doesn't show the 4G+ icon like some other Android phones.
Stock Android by default, like on Pixel devices, shows only LTE or 4G.
Attatched picture shows stock Mi A2 on the latest September update using both 2600Mhz + 1800Mhz Carrier Aggregation.

What app is that?

it's NetMonster

I tried this app, and it showed me that I sometimes have 2CC or 3CC (800+1800+2600).
So carrier aggregation works really well.
