What are the differences between Sony Japanese and international phones? Are there any hardware changes apart from the software changes.Why are the Japanese ones so cheap?
There are differents i think and cheap ? Because Sony is made in Japan.
But if you take two of the same type, you can see that the Japanese phone heats up and the signal decreases. I observed it closely with several models. eg xperia 1,xz3,xperia 1iii
They're not being shipped out of the country lol

Only Japanese ones come into my country
How much do you want?
Differences:
1.All JP mdel support "Felica" payment(Some NFC-based stuff requires specific hardware that support it) but global model don't have these so it can't be enabled even with JP firmware flashed.
2.If you mean au/docomo/softbank version(like SO-xxx or SOV-xxx), you might not able to use it THEORETICALLY ouside Japan or with other carrier, the bootloader is not unlockable in these model as well.
3.These model mentioned in (2) only have single SIM slots and lower RAM/storage in past days, not sure if it's the same for recent model.
Why it's cheap:
SONY is pushing carrier free smartphone forward in Japan, you can purchase the carrier free model now, but I think the model you mentioned most likely to be the carrier specific model, and that's why it's cheap, I guess.

I am from Norway and got my Gear S as a gift at the Samsung Developer Conference. It was locked to AT&T. I unlocked mine using cellunlocker.net. I received the network lock code less than an hour after submitting the order and it worked like a charm.
However, here in Norway we have GSM 900/1800 and the AT&T device is only GSM 850/1900 from what I can find on the net. Which matches my end result of not being able to connect to my network even after unlocking.
I should probably have thought of this before spending 29USD on an unlock code, but anything less than Quad-band on a phone just seems so '90s. As I do not have a compatible Samsung Phone either, the device is pretty much useless for me without GSM. I have Sony Z1 Compact (great), iPhone 5s (meh), Lumia 920 and 1020 (great), so buying a new phone is not an option at the moment.
Is the GSM-bands controlled by firmware or are there hardware differences between the US and European versions?
Does anybody know if it could be possible to load a European FW and get GSM 900/1800?
I'm fairly sure that's hardware controlled. Sorry
I also wish these were quadband.
You could try to sell yours on Ebay.com (I see they are currently going above suggested retail price), and buy one in Europe. They are, however, a bit more expensive there, EURO 390 in Germany including tax, for instance, but they also don't have SIM lock there.

Have you tried contacting your local Samsung Developers on Google+? Samsung Developers US are very responsive on there.
I can't believe they didn't think about that!

Yes, but no luck. Says there are differences in the hardware and that it cannot be changed in software.

I mean contact them to find out if they can replace it with one that actually works where you live.
Hi. I had the international version of the Z5C until it recently died on me.
I decided to buy the US version of the Z5C to replace it since it comes with warranty.
Someone on reddit told me that I could flash my Z5C to enable the fingerprint sensor.
I'm new to all this and I was hoping one of you could show me the way to achieve this, which wouldn't leave me with a 2nd brick.
Thanks!
I am not sure if that's possible but if so it would more than likely require you to install stock ROM of different country through flashtool.
I ordered e5823 through Amazon prime in States and it came with sensor working, so it doesn't necessarily mean it won't work. I believe when people say US version they mean carrier locked phones as z5c has only 2 different model numbers as far as I know with all LTE and 3g bands working on either model, refer to GSM arena model comparison for more info.
I see that B&H Photo sells XQ-BC62 model in US as "Sony XPERIA 1 III Dual-SIM 256GB 5G Smartphone (Unlocked)", i.e. the dual-SIM capability is explicitly claimed.
Meanwhile other US web sites (e.g. BestBuy) also sell XQ-BC62 model in US without mentioning the dual-SIM capability.
So, is XQ-BC62 sold in the US a dual-SIM phone or not?
I understand that Sony devices whose designation begins with X are supposed to be dual-SIM, at least hardware-wise. But there could be software differences, right? Or not?
---
A more specific question that interests me is about future AT&T compatibility. The AT&T's compatibility list clams support for XQ-BC62. So, does it mean that the dual-SIM phone from B&H is going to be supported? Or is there a chance that it will stop working on AT&T network after February 2022, despite being on the list?
Uh... Sorry. My mistake. BestBuy page also says it is dual-SIM. Missed it.
Everything's clear now.

As shown on GSM Arena, all model numbers of the Xperia 1 iii are hybrids. That means they have one regular sim slot and one sim/sd card slot even though only one of the two sim cards can use 5G at one time.
I did have the same experience when ordering my Xperia 10 III. On the website I ordered from. It said it would only have one sim slot. But I did some research and found out it was a hybrid, which I did confirm on delivery.

Don't count on Telco support improving. All Sony needs to do is update the firmware but that hasn't happened. Only upstream security patches and critical bug fixes (boot loops, firmware self-destruct, and dangerous overheating) have been released. I haven't seen any badly needed performance or usability fixes.

Would you be kind enough to elaborate? I own this phone, and though I choose to run Nova Prime, I have no usability or performance issues at all!

I put a post at https://forum.xda-developers.com/t/xperia-1-iii-and-xperia-pro-i-fatal-flaws.4374813/post-86157973
Many countries are releasing phones with dual sim, but there are some countries like Japan that does not provide dual sim, Many phones in Japan does not support dual sim.
After some frustrated googling I feel like I'm coming up with bupkiss. Can anyone help me understand the differences between the xq-be72, xq-be62, and xq-be52?
Are they for different countries/regions?
Any hardware differences?
Would one work better in the US?
Cheers
Strictly region differences. The USA model works best for the USA though since the respective models get the best bands for their native regions. USA is finicky as you know and uses specialty bands. I have an HK model, the 72, but live in Canada. It's definitely not the ideal model but I didn't care as I got it at killer price.
This is highly not recommended to run in rhe USA tho
Which model is for the US, 62?

Hello.
I have a question about the s23 ultra about how to check the modem used in it, I am asking because I know Samsung will try to cheap out as much as they can, the point is I know they should use the new x70 modem but in my region, the phones come with no antenna that found below the power button like the American models, so I think Samsung used their standard modems they usually use here in the middle east.
device info : S23 Ultra sm-s918B/DS
Baseband: S918BXXU1AWA6
AFAIK the modem is part of the CPU chip, so I doubt its different.... For sure frequency bands are significantly different between US and EU/elsewhere, therefore a different antenna configuration makes sense for me

American models have mmWave... None of the others do.
Thank you for the answer guys, I just did ask because I always feel that our copy is made cheaper than the American models although we pay more, I did pay 1400$ for a 512g copy as a promotion of double the storage, and got 300$ total value stuff from them.
