E6603 vs E6653 Difference - What to do?

Hey all,
So Handtec just released what version they will be getting and its the E6603, seems to have all the bands necessary for AT&T. There is also a E6653 available from Clove, I looked at the developer thing from sony, there seems to be no difference in the bands. So what is the difference in model number.
With that said... I have been rocking an iPhone 6 Plus the last year. This is my first iPhone and while it is nice. I have been itching to get back to Android. I got an invite to buy a Oneplus 2 and bought it, now I'm regretting it. The sony seems like the device to get, I rocked the z3 for about a month when it came out. I have thought of using the Oneplus for a month until the Z5 comes out, but not sure... Thoughts?

only difference as far as the whitepaper goes is that the e6603 supports cat4 LTE, and the e6653 supports cat6

Hi ,
Here is your most appealing thing so that is the(the whitepaper goes is that the e6603 supports cat4 LTE, and the e6653 supports cat6 )

Do we know which one will have an unlockable bootloader? Or is it too early to know?

none of these seem destined to head to T-Mobile as a specific variant, so both can probably be unlocked, as per usual.

Ordered E6653 today, will be here next week.

HELP???
I live in the usa,and ordered the e6603 from handtec. Should I get the cat 6 capable e6653 from clove instead? Also I can't seem to find that model on clove.

Really a personal choice. If the only difference is cat 4 or cat 6 LTE it doesn't really matter. I ordered E6653 because its available now from a seller I have dealt with on numerous occasions in Taipei.

I assume this topic also goes for the compact models as the white paper shows the same differences. Still torn between z5 and compact but was considering doing it now from probably the same eBay seller. I'm in the USA anything I need to worry about ordering one of those phone such as it being stuck on another language or being locked (if they claim its unlocked which I do believe it is)

I use eBay seller 23port. I have purchased a few phones from them and never had an issue. Always brand new unlocked devices. Shipped today, arriving Wednesday.

Are we able to use the cat6 lte on cat4 network? At&t still doesn't have a lot of cat6 lte band. If I buy E6653, will I be able to use the LTE for AT&T?

Thank you!!

Is anyone aware of any online retailers that sell the E6653 variant? I can't seem to find any expect bizrus oline which doesn't ship to the US apparent or at least I can't find that option.

For anyone who wanted to know, a reddit user confirmed that the E6653 model is bootloader unlockable.

Any way you could post the link? I've been searching for confirmation on this for days

Device actually arrived yesterday, not bad for shipping from Taiwan on Friday. Anyway, took it out last night and this morning but not getting LTE on AT&T. LTE Discovery app shows band 17 available but the device is not connecting to it. Network setting is 4G preferred. Must have something to do with cat 6 vs cat 4. I am in a fairly rural area in New England. Anyone else get an E6653 on AT&T in a major metropolitan area that can chime in?

Any known retailer will offer the Z5 DUAL Online ?

I'm sure, after using as provisional phone an asus zenphone 2, with dual-sim dual-active a dual-sim phone is now on my check list.
I never read about Sony plans to export to usa the Dual-Sim version (I consider they fail not selling it on amazon) for Unlocked Market.
So anyone known here where to purchase it online?

I live in the UK, and bought the dual sim verison of the Z3 from http://www.mobicity.co.uk/ They might sell the Z5, too - check with them.
The company is registered in England and I paid with paypal - I felt this gave me an added layer of protection. They claim phones have manufacturer's warranty but I am not sure Sony would honour it as I am not sure this model is meant to be sold in the US or the UK. In other words, I took a calculated risk knowing that, in case of problems, it would have been complicated to claim the warranty - which I am never too worried about as I tend to root my phones anyway, which voids the warranty.
Be very very sure to check network frequencies and compatibility. When I bought my Z3 dual, it wasn't compatible with my EE British sim (EE is a network). I had to upgrade the software. Searching on forums it turned out that other networks have the same problem, too. Anyway, I have had my Z3 for almost 10 months and I'm very happy with it

Thank you, I've checked the frequencies for the dual sim version and has no issues or restrictions with T-Mobile or AT&T. (LTE 2,4,12,17 is on both dual sim versions).
At the moment there is only one retailer selling it thru Amazon, but a bit expensive (900$) I hope soon more retailers sell it.

I got mine from this eBay retailer: www.ebay.com/usr/qd_us He has the dual-SIM variant too, and prices are pretty good
Mine was shipped from Taiwan to Canada in 3 days.

Sometimes just checking the frequencies is not enough.
Look at this thread: http://forum.xda-developers.com/z3/help/z3-dual-d6633-sim-compatibility-issues-t2932027
The D6633 (Z3 dual sim) had a firmware that was incompatible with some carriers, and only once a new firmware came out did the phone become compatible with those carriers (EE in the UK and some others).
Why? I have no clue...
Of course I wish you won't have any issues, but bear in mind that, should you do, you may have very little recourse if you bought from a foreign vendor that, well, never guaranteed compatibility with your specific network.

Potential purchase of LG G Flex 2 from Expansys

Hello
I'll start by saying thank you for taking the time to read my post.
Unfortunately, my Z3 Compact suffered water damage and as a result has been playing up, I'm therefore looking to replace it with a similarly capable device without spending too much money, one device that has stuck out to me is the LG G Flex 2, I'm a big fan of the design and particularly interested due to the price it is currently available for at Expansys.
I am however aware that the G Flex 2 did initially suffer from some performance issues, I've noted that some users on this forum have stated these problems have gone away since the device has been updated, however with Expansys selling a non-UK model (I am based in the UK) and thus shipping an EU one, I'm unsure of whether the device I will receive will actually be able to be updated to fix said issues, is anyone aware of whether or not the retailer is shipping updatable models or whether the device will be stuck on an outdated firmware for a long time? I'd also like to know whether the warranty would be honoured in the UK, although I have noted the site states the warranty is EU wide.
I'd also appreciate any other comments and things you have to share regarding your experiences with the device as well.
Thanks again for your time

- Performance problems are mostly fixed with the latest update. You can of course tweak it further with root and the available mods
- I bought a device in Austria and updates work fine in Germany
- I also sent it in to LG in Germany and they honored the warranty
How much are you paying? You can order it from Amazon Germany for 255 Euro.

The price is currently listed at £214.99 (2GB RAM/16GB ROM) from said retailer, although I have found another reputable store here in the UK, which will also sell the same version for £204.99, both include delivery.
My biggest concern with the purchase, is ending up with a device where I can't get updates due to it possibly being from a region, where updates aren't rolled out, seeing as both retailers don't specify which country their EU models are from.
I'm not sure if this is something that LG do with their devices, but I am aware other manufacturers roll out updates at different times dependent upon the region and as I know the updates have fixed many of the problems, it worries me a little that I could have to have those problems for however long I own the device, I don't know if anyone could clear that up for me perhaps or shed some light on the matter?
EDIT: I've taken a look at the Amazon listing, I believe however my bank will charge me for using €, I know I had some pretty big fees abroad, lol.

Like I said. I don't really think it matters where you are within Europe except Russia maybe if you have a EU model. You should get updates everywhere. As far as I know there is only one variant sold in Europe which is the H955. The UK model also seems to be the H955.
http://www.lg.com/uk/mobile-phones/lg-H955
I think they determine the country-related-updates via IP oder IMEI anyway.
As I said I wouldn't be concerned about it. Also there is the possibility to flash the .kdz-file manually via LG Flash Tools. I did so when the 15d version became available in Switzerland but not in Germany which was still on 15c.
Yeah, the banks are greedy bastards when it comes to conversion rates.

Is Anyone Ordering (or Pre-ordering) a U.S. Ver. XZ Premium???

I'm curious to know if anyone here is going to purchase the U.S. version of the phone and use it on T-Mobile or AT&T. Current pre-order sites are Amazon and Best Buy.
I currently have HTC U11 but have always been a Xperia fan and I'm really liking what Sony is offering in the XZ Premium so on a whim I decided to pre-order the phone.
I have T-Mobile for service so I'll be trying it out on that. My concerns are no VOLTE and no WIFI calling. I've been testing my LG V20 for the last week with VOLTE and WIFI calling turned off and it hasn't been an issue or bothered me at all so I think that I'm good there. Another thing is that it's missing the software for fingerprint sensor. I can live without the fingerprint sensor so it's really a non-issue to me but I understand that it bothers others.
Let me and others know what you think about it. Have you pre-ordered or will you order it? Would you use it on AT&T or T-Mobile?
Thanks!
UPDATED: So it appears that the phone I pre-ordered from Best Buy has the model# 8142. This is the same model number for the UK phones per the info from https://www.techwalls.com/sony-xperia-xz-premium-g8141-g8142-model-number-differences/. If this is the case then I guess that I am getting the international UK model, just from Best Buy. The phone listed on US Amazon doesn't have a model number so I'll have to say that it's unknown until someone orders it and can update me. Per that website there is a G8141 but I don't know who is selling it in the US.

Hi - I've ordered from Unlocked-mobiles.com (UK). Its ~100$ lesser + Bluetooth speaker ($150 in BestBuy) not to forget the Sony international warranty. Also you don't need to flash anything since the FP scanner works out of the box. I am using with Tmobile and haven't noticed any issues so far. Several in the US have got it from UK as per the other threads in this forum

Thanks for the input. I guess that a big deal for many is the cost difference between a UK version and a US version and that alone may drive them to opt for the UK version. It's too bad that I'm not too keen on purchasing a phone from UK and bringing to US. I'd rather purchase the US version from Best Buy and include the accidental damage plan to have that extra coverage as well. As a note I haven't owned a Sony phone since the Z3 from T Mobile and believe me I'm pissed that T-Mobile hasn't had a Sony phone since.
If the phones are identical (I think that's the case) then I could flash the UK firmware onto it and use as normal until (if) a warranty claim is needed then I can flash US firmware and off it goes. :good:

I'm interested in purchasing this phone at Best Buy as well and using it on the T-Mobile network. For those that have purchased and on T-Mobile, does the Wi-Fi Calling feature work? I love that it has dual sim capability for when I travel abroad, but I do use Wi-Fi calling just as much. Any input would be greatly appreciated! Thanks in advance!

The unfortunate answer to that question is a definitive NO. Something about the fact that Sony doesn't have the device certified by T Mobile is what I heard. Same goes for the VoLTE.
I still use it on TMO though.

Question USA Customization on xperifirm

Hi,
I'm trying to get my Xperia 5iii vowifi working on Freedom mobile in Canada.
I want to test if they USA customization would work.
It might not, I see my XA2 H3123 had a customization for Freedom, which I know won't exist on anything newer.
I can see in xperifirm a usa customization for the 1iii with firmware 61.0.A.23.20
For the 5iii there is no USA customization but has the same firmware number.
Is there a usa customiztion on the way? Or can I download the firmware for the 1iii

It seems the phone is not out in the US yet. That’s what I’m waiting for to pick one up. I’ve seen pre-orders at US retailers saying Jan 11 is the date they will ship. So, you might find the firmware in a few weeks. I wouldn’t recommend trying to load the 1 III firmware.

Hi @Yakkosmurf ,
Thanks for the reply!
I'm really torn between trying to get this to work, and selling the device before messing around with it.
I think I'm going to give the MBN method a try

Any updates on this?
Several news articles say the 5 iii is out in USA now, but I cannot find any stores shipping or carrying it in north america (Canada)
I do find shippers selling what they call the "international version", apparently versions from Taiwan or Hong Kong.
If it turns out the "international" 5 iii is the same as the USA 5 iii and can just be reflashed to USA (I did this once with an older xperia) now the USA 5 iiithen that starts to look like a possibility…

Confusing me further the "international" XPeria 5 III is model number XQ-BQ72 and the USA model number is XQ-BQ62. No idea if there's an actual difference.

Hi @mcc111 ,
I'll tell you what's happened with mine. I bought the XQ-BQ72 and it does work on the networks here, but you can't get any of the added services like VoLTE or VoWifi (this one was important for my uses).
I tried flashing most of the roms from XQ-BQ72, but it seems the problem is there needs to be a configuration file in the modem, which basically won't exist if they haven't launched in the country (none for Canada).
I then tried flashing XQ-BQ52 which seems to be the European model, but that was even worse. The signal would connect and disconnect repeatedly, so there might be some hardware difference keeping it from playing nicely. Or, the 52 just has modem settings that don't work here. But I am not experienced enough to know which.
Because of that, I doubt flashing the 62 is a good idea. I haven't tried because I gave the phone to my wife who doesn't need the extra network features, and it'll be a headache to take back to screw around with more.
I bet since the 62 has been launched, it'll be available online eventually.

Can you discribe who you got to flash the os? I tried flahstool but it didn't recognize my 5iii, then I tried newsflasher and got stuck in a boot loop. Saw a couple people in the newflasher thread getting bootloops as well.
Do you mind share your process?

There is a solution reported as working for both Xperia 1 III & Xperia 5 III posted here: https://forum.xda-developers.com/t/5ii-1-5iii-volte-patch-guide-to-release-the-root.4363269/

So, can anyone confirm that they were able to Flash a Xperia 5 III US Rom with 5G working, VolLTE and Volwifi working?

I used new flasher.
Newflasher guide to install new firmware for Xperia XZ Premium, XZ1 and more | Xperia Blog
One of the most frequent questions we get asked from Sony Xperia owners is how to change the firmware. Whether that relates to upgrading/downgrading major Android versions, debranding the handset or simply changing the firmware region for faster updates. Using
www.xperiablog.net
This was a few months ago. My flashing to other firmwares for the same model worked fine, but none had the modem configurations to work with freedom. If I flashed the other model, my cellular connection wouldn't work properly.
I haven't tried the USA version, and can't as I gave the phone to my wife who doesn't need the wifi calling.

I couldn't get this to work in Canada, but I'd love to hear if anyone else got it to work.
My understanding of this method is your configuration files need to exist on some other version, which it seems mine were not.

A note, it turns out that the XQ-BQ72 (international) and XQ-BQ62 (usa) actually support different bands. The XQ-BQ62 supports more bands. You can see this on this site and some other places: https://www.phonemore.com/compare/p...xq-bq72-vs-sony-xperia-5-iii-xq-bq62/17024281
The bands missing on the XQ-BQ72 are N20, N66, and N71.
No idea whether the remaining bands are adequate for USA 5G and/or on which providers.
I eventually got a XQ-BQ62. I'm having some issues with it but I'll make a new thread for that.
