Hello everyone. Just have a question about the Z2.
So say someone bought an UNLOCKED Sony Xperia Z2 and used it on T-Mobile's network. T-Mobile does NOT sell the Z2 officially (previous models were like the Z1S, but not the Z2). The Z2 is from what I've read capable of LTE-A. T-Mobile just started deploying updates to its official customers (ppl who bought phones from them) which included the enabling of LTE-A. Some phones like mine (T-Mobile HTC One M8) have LTE-A, but it's not enabled until I get that update, which will be very soon. But what about the Z2? Will the unlocked version have LTE-A already enabled?? How does it work?
I would really appreciate a clear and detailed answer. I'm curious how that all works. I almost bought the Z2 but b/c of the big delay in it reaching the states officially (a week ago lol) I got the M8 instead, which I love now, esp after rooting it. lol I'm wondering what I would've done if I'd gotten the unlocked Z2 instead.
Thanks,
RockStar2005
Note quite. First, NOBODY in the US has LTE-A, or currently has publicly announced plans to rollout LTE-A
The unlocked Z2 supports all current T-mobile, 2G, 3G, and LTE bands.
T-Mobile is currently in the middle of deploying 2 different LTE related technologies. The first is VoLTE, which places calls over the LTE network instead of the normal GSM (GSM, EDGE, HSPA) network. The second thing they are doing is rolling out 15x15 and 20x20 LTE, which is increased data speeds.
With that said, the Z2 should take full advantage of the 15x15 and 20x20 LTE rollouts. I'm not sure about VoLTE however, although it seems unlikely to support it. The rollout you were referencing (HTC update to enable a feature) is VoLTE. I spend a lot more time on data than on voice so for me it's much less of a concern.

The Snapdragon processor in the Z2 CAN do VoLTE, but Qualcomm says that the operator has to certify the phone (and radio chipset) for VoLTE first. Then, Sony has to provide a firmware update to enable VoLTE for the network, T-Mobile in this case. Don't hold your breath, this could take some time.
Hi, some of you know the 4G frequencies of Honor 8x (No MAX). Is that there is controversy in some sales pages and in the Chinese official does not clarify.
In some they say that they have the B7 and in others they do not, thank you very much for your help.
it's rolling out now. well see as reports come in. early results this will not work LTE & vokte in USA TMobile or ATT. I am wondering if there will be different versions.

The phone is releasing in the US, they even held an event in NY recently...

What's not clear is whether it'll support B46, B66, and B71 for T-Mobile.
band 71 will probably make it break many unlocked phones in the USA. myself I won't buy one unless it has band 71 and preferably band 66 as well. no one works volte with ATT and OnePlus is preparing to sell thru T-Mobile

If this representative is right we might not have to wait long for band info. Huawei phones usually launch around Oct - Feb.
The Honor 7x, View 10 and Mate 10 Pro feature 2, 4 and 12. So I'm a little concerned about the company's support for newer bands in the US.
I do not have high expectations for band 66 and 71. i want to be wrong though
Haha. I'm trying to stay optimistic. Very few phones around ~$200 carry a battery this size and certification by Rheinland. If Huawei disappoints there aren't any real alternatives.
Well, no. There's the Moto G7 but that's several months away.
Thread title.
The rollout is well underway. Could one of you gents within range of one of the towers please force band 71 on, and see if you get any signal?
No.

Well, that's unfortunate.
It's an H932 on the shopping list after all, then.
We don't need band 71 though to operate on T-Mobile right? I mean I have a V20 and V10 and they don't get band71. It s just newer phone correct?

Strictly speaking, no. It's not a CDMA sort of situation, lack of band 71 isn't going to make any phones outright obsolete.
T-Mobile is rolling it out hard to improve their coverage, particularly in places that don't have a signal now: rural areas for instance, the sort of places where Verizon has reigned supreme for entirely too long. I would say that band 71 is TMO's Verizon-killer, but I know better...it's going to take more than stiff competition to rid the world of Verizon, unfortunately.
It's not completely rolled out yet, but I figure if I'm going to get a "new" phone and switch to T-Mobile, I might as well future-proof a bit and be able to use their full network once it gets there.
This is a little OT...I remember reading that apple wasn't going to have any phones on tmobile that supported the new band. But it seems that is untrue with the latest release of iphones.

Yea, that was the case with the 8 and 10. If I recall right, they were using the Intel radio prior to the one that supports band 71.
There was apparently quite the push to get the H932 out as the band 71 flagship, with the probable intention to boost contract sales for more money to do the rollout with. Poor ol' T-Mobile didn't realize (until it was way too late) just how bad LG's marketing and PR departments are, I guess. What a mess.
Seems the later-2018 iPhones do include support due to a newer radio, though, along with a bunch of other 2018 phones.
Hi there,
Like many other customers who does not live in countries where the Google pixel 6 has the 5G unlocked, I was hoping that Android 13 would unlock this.
I saw on some posts that the Beta version of Android was unlocking this "feature".
It's quite a shame that google chooses to lock it only to specific countries. My network provider uses the same bands as some other eligible countries provider but I can't get 5G because of what ?
At least it would be nice if google explains their decision.
I know some Google employee here and their devices have 5G unlocked on their phone (being in the same provider as I am).
They had no idea how I could unlock it on my phone though.
Not having 5G isn't that big of a deal with 4G big good enough for most use. But that's a pity it's being taken away from paying customers for no specific reason.
Does anyone have an authoritative link or source for the different S23 ultra regional model variants and their respective bandwidth frequencies such as for 4g and 5g?
Can't find this information for any including the USA variant eg which specific frequencies of 4g and 5g does the USA model support?
The chipset and x70 modem makes it possible for this phone to truly be a global phone but.....
asking the same as well, cant find these details.
Here's hoping that the band unlock methods for the s22's and s21's also work on the s23's.

I'm sure it will be the same to unlock the bands, no one will really know until they have one in hand.
Can you elaborate on these band unlock methods?
And could they unlock mmwave for example on the international variants so that 5g could work in US? And unlock international bands on US version so it could work everywhere else?

This is the thread you probably want to have a look at. This method also worked for the s21's.
How to Enable All Bands Through Service Menu on US/CA S22 series (including Sub-6 and mmWave)
What is this? This is a guide on how to enable all LTE and 5G bands on the US or Canadian S22 series phones by going through the service menu. This guide is mostly based on this S20U guide by mellojosh, but has been adapted for the S22U phone...

Interesting....
So basically you could enter the service menu and turn on all the extra bands?
In that case wouldn't the US version be the best one to have since it would have mmwave hardware baked in too? It should then work everywhere.
Though it sounds like you'll lose the function on os updates and resets?

OS updates from Samsung are never fast. Doing so once every 2 to 3 months isn't so bad for the extra band support.
Samsung's modem software works well for the US and Canada because the hardware is the same and only the modem software separates the bands based on carrier/region. Due to the wide spread of mess across North America, US and Canadian models are always a good choice for potential band support. In some cases though, mixed ROM's can also bridge the support. In the S9 days, you could.jeep.the base.for.your region but flash the carrier side of the firmware to unlock band 71 on some overseas models. I don't know if this is still possible today but with all devices being very similar. I am hoping the hardware, including dual-SIM pins on the main board, will be there to enable through a firmware change or mod.
Do we know if the international dual sim variant has the same USA hardware based on s22/21/20?
Does it have mmwave baked in but just disabled by software?
I am still not clear what 5G bands are supported on the SM-S918BZKPEUB, nor if unlocking the bands through the service menu works. @UK S23, your deliveries are in place already, has anyone tried?
It seems as though the bands might only be disabled in software? If so, then it should be possible to enable whatever band you need. The only exception would be if a hardware component is needed or missing then it wouldn't be possible which likely wouldn't be the case for your 3g, 4g and 5g standard range. Maybe only 5g mmwave which is essentially only in US anyway.
If that's the case it sounds like US variant might be the best to get for global coverage barring lack of dual sim (though it does have physical+esim).

Samsung's band support is mostly software, at least when it comes to 4G and 5G. I have never bothered to change 2G and 3G bands because there is no use for them unless you are in a very rural area or roaming. This is why it is so easy to convert the North American models and why in the days of the S9+, you could get band 71 on international models with dual-SIM.

Correct me if I'm wrong but you can't get mmwave bands on the international dual sim models right?

I'm not sure when it comes to mmWave. You can enable it on the W for Canada even though the cell coverage and technologies used up there are probably never going to deploy it. Overseas, I have no idea.

I've read that the US and CA models are basically identical so that might explain it. It's also possible I suppose that in s23 since it uses x70 modem, which has native support built in, that all model variants might be able to do it but for software. Though we won't know for sure till someone from different region goes into their service menu and checks.
mmWave requires a specific antenna to function. This antenna used to cost like $50 but I'd be surprised if it's gone down much beyond $30 so manufacturers will still leave it out if it's not necessary.

Thanks and that probably means it likely won't be in other region variants.
Personally, I'd just make a single phone that is globally universal and can be used everywhere. The massive scale should drop the component pricing considerably. Carrier exclusives and market restrictions if any needed in software only. But that's just me lol.

Yes, you would think they would do this, but Samsung has always customized difference models for different regions so it must not be that straightforward. I believe that regulatory bodies would require them to test and submit all the documentation for that extra antenna, for example. It also wouldn't surprise me if the mmWave equipment is outright banned in some regions either for whatever reason.

No. There are 5 different models of iPhone 14 Pro Max, for example, and each will have different band configurations.
That said, the NA models have the most complete bands of any device released so far this year and it was released last year with an older modem. They even have support for Dish Network's n70, a band exclusive to them worldwide, something Samsung didn't even choose to support on their NA variant this year despite having a contract with Dish for radio equipment supporting that band.
I actually think the NA iPhone 14 Pro models support every commercially available band worldwide but I don't really keep up on bands not used in the US.
