Hi everyone,
I wonder if someone can help me, i have asked a smart guy this question and it was suggested that i try it with AU's FW..but im a little new to this and i need some help...
This phone Xperia Z2 has LTE band 17 (700Mhz) .....but here in Australia we will be getting LTE band 28(700mhz)....
Can my phone work in the B28 if it does not say B28 in the specs? because its still 700mhz.
Or do i need software to allow it to operate on B28 (700Mhz)?....maybe some settings, or flash of some sort.
Can someone help...
Thanks.
Depends on where did you get it from? I purchased my XZ2 from Telstra.
And it is same spec as international one whch doesn't support 700Mhz LTE.
Optus might has got special model and I am not sure abou that.
Only little hope for software update, as they have to register this phone to
certification of conformance to technical standards again.
I think you can flash AU FW by using tool called flashtool. Howevery by using that
tool your warranty may avoid so think carefully.
Yes i got it from Telstra....Mine has B17 which is LTE 700Mhz ....Im pretty sure.
Its the B6503 which has
B1,B2,B3,B4,B5,B7,B8,B13,B17,B20
I looked up the Spectrum allocation and it says B17 is 700Mz...also B13 is but its different allocation of that band...
Im guessing it just needs a Software upgrade to make it work on that allocation of B28,
But im not an expert and im not really sure how its done or even if it can be done.
Thanks.
Oops I meant B28... not B17. Collect my mistake.
There are 4 versions of the Z2 sold.
D6502: No LTE
D6503 (AU, NZ, EU, ASIA model): LTE bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 20
D6543 (North American model): LTE bands 1, 2, 3, 4, 5, 7, 8
SO-03F (Japan model for NTT docomo: docomo Xi LTE
Yes,
But is there a way to allow the ones which already have B17 & B13 (LTE 700Mhz) to work on the AU LTE 700mhz B28?
There must be a way to unlock that specific section of the LTE 700Mhz (B28) on this phone considering it already has the capability of 700Mhz LTE.
For example [(B17)-Uplink =704-716 Downlink=734-746]---------[(B13)- Uplink =777-787 Downlink=746-756]---------[(B28)-Uplink =703-748 Downlink=758-803]
Is there a way to operate on the B28 frequency range within the 700Mhz band considering the phone has a 700mhz LTE chipset?
There must be some way to do that. But as I said in my post. It must be authorized by Government or whatever
authorizes the phones with which band and which frequency the phone uses.
So if you change it by your self it would be against the law and should not happen.（As I am not Australian I am not sure about Australian laws)
I have read some thing about changing frequencies, but I can't remember and it must be done by your own.
Anandtech mentions it is LTE-A Category 12 (600 Mbps)
Some sites mention it is Category 6 (300 Mbps)
So what is it exactly?
With the new Non-HLOS.bin shipped with 17 S, there ist no cat 6 LTE , only 150 Mbit cat 4. The + sign at 4G sign doesnt appear
So should I go back to Indian 16S ? I am aware Indian 17S or 18S is on the verge of getting officially released. I prefer the Chinese 17S because battery is absolutely brilliant after removing the bloat. Indian 16S has horrible battery and standby time.
How to check the LTE-A ? I'm on CN 16s, in Malaysia (CA Band_3_7).
Whenever my phone show 4G+, then phone signal will drop for total no signal, can't call or data (Searching mode)

CN 16s and older ROMS are worthless for LTE. Try with Indian 16S.

Cannot tell as my operator is going to start CA soon in my area. People are saying that Indian 16S supports CA while Chinese 17S and below do not support CA.

If you get a chance please post your modem version. Thanks.
Snapdragon 820 has X12 modem (category 12 LTE up to 600 Mbps). I have had 4G+ for ages (in Japan on OCN Mobile One, an MNVO on the docomo network). However, as it is an oversubscribed MNVO my speeds are never great and even when getting a CA (4G+) signal they don't really change. My current firmware baseband version is as per this screenshot:

Unfortunately even on the same base chipset some of the radio params are up to the OEM, depending on what band combinations LE have programmed CA may work with some networks and not with others (eg OCN might be using 20Mhz x2 in 800Mhz while ThreeUK might be using 1x 15Mhz on 1800Mhz and 1x 15Mhz in 800Mhz).

Yes, obviously availability of CA depends on carriers and on the LTE bands available to the device. Not all bands are turned on for our device so some people some places are going to be SOL. In the case of OCN the carrier aggregation is probably working with bands 1 & 3 I guess (the other bands OCN use are 19 & 21, which are not available on the LeMax 2).

Ok so far then:
272-05 Three Ireland B3, B20, B8 Not Working
272-01 Vodafone Ireland B3, B20, B8 Not Working
440-10 OCN Japan (NTT) B1, B3, B19, B21 Working
Probably should just google what bands CN Mobile use for CA, that'll be the only thing LeEco will bother to implement in the baseband.

CA is strange. My friend has a Moto Z Play he bought direct from Motorola Japan. He is using OCN, same as me. His Z Play has the same available OCN LTE bands as my LeMax 2 (B1 & B3) and Motorola say it is CA compatible, but while I get 4G+, he doesn't. And another friend has a Japanese version ASUS Zenfone 3 and he gets 4G+ on another MNVO using same docomo network with B1 & B3. So it seems to be a bit of a lottery depending on your device & your region & carrier.

Compatibility isnt straightforward as its also dependent on resource blocks or RBs. Some radios can handle CA 2x 2x20Mhz and some might only manage 2x 2x10Mhz. Thats why reading the RRC messages between tower and handset is useful as OEMs dont release the full config that their UEs broadcast.
Snapdragon 820 aggregates 3 frequencies (3CC). I never managed to force him to do it, but 2 can (2ca).
I am looking to buy this phone, but am very cautious because it isn't officially available or supported in Canada. So I am wondering, from those here who have done purchased and use this phone as their main one, what is the Xperiance (heh) like? What works? What doesn't work? Would you recommend it?
Also, what version are you using? I've found a few websites selling the US variant (XQ-BC62), but most of the sellers have the Chinese(?) model (XQ-BC72).
I've read this thread, so I understand that I cannot just simply purchase a non-US model and flash it with a US rom without having LTE issues and no apparent benefit. Was really hoping that was a feasible option to maybe get some carrier features to work. But honestly, I don't care for 5G (besides, Freedom Mobile doesn't even offer 5G), I don't think I have ever used wifi calling, and I doubt phone calls with VoLTE are vastly superior to voice calls without it, so losing out on those features isn't the biggest issue for me. I just want a phone that works, though, and not something I will constantly need to fight with to keep working.
So yeah, if anybody has anything to share, I would greatly appreciate it!
I'm coming to the Xperia 1 III after having a SA 5G phone and IT MAKES A DIFFERENCE. The Xperia is always suffering from spotty signal problems while my older T-Mo LG Velvet 5G is solid everywhere, despite the two having the same public spec sheet. The Xperia likes LTE 66 + NR 71, which makes absolutely no sense. LTE 66 is fast but a bit unreliable while NR 71 is ultra-reliable but slow. The Xperia can't operate without LTE 66 so NR 71 is just there to drain the battery and turn on the "5G" indicator. It can't seem to use NR 41 at all. The LG typically uses the best three of NR 2, 4, 41, and 71.
Think about the future:
HSPA is as good as dead. What little of it remains is badly overloaded. No VoLTE/VoNR will soon mean no phone calls.
Newer bands are 5G only
I don't know if it's the latency improvements or the way 5G/LTE bandwidth sharing works, but a saturated cell tower performs a lot better on 5G than LTE.
I'm hoping Sony fixes the BC62 soon or this will be a $$$$ mistake. A bad cell radio is no fun.

Well that's extremely frustrating to read...
The one phone that checks all the damn boxes regarding hardware, and of course it doesn't actually work well as a phone. You had one job, Sony!
At least that is something that can be fixed, right? But yeah, I'm not really down to spend $1500 CAD on a phone that might work...
I am in Canada and I have XQ-BC72. I am on Fido and I also tried Rogers wireless sim card. NO VOLTE SUPPORTED. Not only volte, no carrier feature are supported (volte, vowifi, voicemail, visual voicemail). However, basic LTE function works fine. The network speed is very good, I think the speed is the standard speed.
A funny thing is I didn't have 4g+ support when I first came to Canada. The network speed is about 40mbps. But I got 4g+ support after I inserted a Rogers sim. I mean insert a Rogers sim and take it out and then insert my Fido card. The 4g+ sign disappeared in a few weeks but the network speed seems remaining the same, which is more than 100mbps now.
Also if you're interested, it doesn't support 5g on Rogers. It might because it's on TW rom, but I don't want to flash my phone and try again since flashing ROMs in other areas makes LTE unusable.
Flashing ROMs doesn't help on carrier support. I am trying to get the carrier support by unlocking my phone this winter. There's a guide on XDA, you can check.

I'll wait before pulling the trigger then and see how it goes for you. I tried contacting Freedom Mobile to see if there was a chance they approve this phone for their network, but the response was basically "we don't recommend getting unsupported devices, just get a Samsung" lol...

I think it is okay if you don't care about 5g. I'm here using the phone for three months without any problem. Actually, I don't use voice calls that much and I don't have any scenario that I need network while calling. The 3g call quality is fine and I think even better than WhatsApp. It's a good phone for daily use though.

According to this website (www.cacombos.com), the T-Mobile LG Velvet supports more carrier aggregation combos with 5G on T-Mobile:

Whereas, the Xperia 1 III can only pick up that Band 66 + n71 if it is also paired with LTE band 2, apparently:

Hey, I unlocked my phone and did some tricks to toggle VoLTE and VoWiFi on. But, unfortunately, my phone provider Fido and its mama Rogers wireless don't support non-fido and non-rogers phones. Posts on the fido forum can confirm that. So, I cannot ensure if the VoLTE really works on my phone, but I've tried a Telus SIM card before I did my tricks; the result was the voicemail appeared in the dialer app, which is a good sign isn't it?
I read the post in the forum for enabling VoLTE but I cannot understand even a word... So I didn't try the method in their video and post. In addition, there's a lot of difference between South Korea and Canada. The Qualcomm software seems to recognize his carrier in their video but my Qualcomm software didn't, so I gave up following their guide.
If you want more information about the trick, I created a magisk module and you can try on your carrier. I think Freedom is not blocking non-freedom phones. I also see someone succeed in getting VoLTE by adding mbn files.

Hey Do you have a link to someone succeeding in getting VoLTE?
would this work on the 5iii? It looks like this is the pixel mbn.
@astracd had said because the chip is different, it wouldn't work on the xperia.
Yes, you guys need to find mbn file from phone with same chipset that has mbn for rogers or fido.
Hey. I got 5G, VoLTE, VoWiFi work on my phone. The bad news is there's only mbn files for Rogers, Bell and Telus.

Never use non-Rogers or non-fido phone with Rogers/fido. Even though we have the mbn files. I was with fido and I borrowed a Rogers sim for testing. Sadly the results was I can't have anything work on fido and only 5G worked on Rogers but slower than LTE. Non of them has VoLTE or VoWoFi working. Rogers the company is famous for blocking phones from registering IMS which is the key of VoLTE and VoWiFi. So I switched to Virgin plus.

I have an XQ-BC72 (intl. ver.). I can guarantee that VoLTE and VoWiFi work on Virgin and Kodoo; since they are the sub-companies, I assume that will work on Bell (Virgin’s parent) and Telus (Kodoo’s parent). Also I can guarantee that 5G is working on Rogers; I guess 5G would work on other twos and speed would be much better if it’s a US version phone since US and Canada has very similar bands. It is proven that VoLTE and VoWiFi WOULD NOT work on any Rogers and Rogers’ sub-companies. I will keep trying these features on other carriers.
ViLTE is not tested because I am still finding out how to trigger the feature, but unfortunately I only have another iPhone with me.
Please aware that all these things would work AFTER you unlock and root your phone. Canadian is not officially supported by SONY which is very weird.
