There is no technical Reasons why they don't sell duos phones.
Some reasons i believe are:
1) There isn't much demand for duos in UK compared to China/India
2) Most of the phones in UK are sold through carriers on contract. So, the carriers will generally lock the phones in such a way that only their carrier works on it. Most of the people won't use two sims of the same network. So, the whole point of Dual SIM is pointless when buying on contract.

Good explanation. However, what about those of us who buy our own devices sim free? That is what I did with my Note II, and had my Note 10.1 been a 3g, I would have bought it sim free too.
I honestly wished companies such as Expansys, Handtec, Carphone warehouse and others were stocking these phones. I normally don't want to be restricted to one network. For business and personal reasons I need to keep separate numbers going.
Thanks for talking to me though.

because of frequency issue.. may or may not be compatible to your carriers frequency

[Q] Differences between single and dual SIM ?

Hi everyone !
I'm planning to sell my good "old" One Max and buy a M8 dual SIM in Germany (m8_dugl ?) instead.
But before that I was wondering if the ROMs/kernels/bootloaders/etc. avaiable in the "Android dvlp" and "Original Android dvlp" forums will be compatible with it ?
I know that the procedure to root it may be slightly different but I haven't read anything about M8 dual sim (in)compatibilty yet.
Since there are differences between Vzw/Sprint/AT&T/T-Mobile/rest of the world versions, I wouldn't be surprised if it was the case.
Thanks !

Buying One plus 5T in the US to use it also with a European Sim Card in Europe

Does anyone know if a One Plus 5T cell-phone bought in the US can also be used in Europe with a European SIM card? I know some phones have issues if you use them in different countries from where you bought them. Is One Plus 5T one of those phones? Thanks in advance!

I don't have a 5T (yet) and have some similar questions about using the dual SIM, but I've done enough research on the various bands supported and available to be very confident that this will not be a problem. I know that my old Nexus 5 worked just fine for me in Italy a few years ago, and in general most unlocked GSM phones bought in the U.S. will work in Europe and vice versa.

There is only one model, so it will work without a probleem.

Dual sim on network blocked s9?

Hi to you all.
I'm about to buy a S9 from Vodafone.
Vodafone blocks the dual-sim functionality on all dual-sim devices that they sell.
However, a year or two ago I came across with a Huawei P8 Lite for my kid and there was a trick that managed to make the P8 dual sim once again.
We had to unlock the device with the proper code and then install the TPH Rom from Huawei.
Do you think that the same thing will happen with the S9?

I don't think so. On Samsung (not sure about others) they do not assign a secondary IMEI on the single SIM versions so that will be the biggest problem even if you find a way to activate it.

My point is that Vodafone does not have single sim phones. They sell the dual-sim S9 but they block the 2nd SIM functionality.
Not a hardware problem.

That might be true for Huawei phones but that has not been my experience with Samsung. Typically the dual SIM Samsungs are a different SKU, they are even labelled as 'Duos' on the device (I am looking at my dual SIM S7 now).

That was true until the S8....indeed Dual Sim models were different from single-sim models.
But with S9, there is no single-sim model in Europe, so the S9 that Vodafone will receive is the same... they just block de dual-sim conectivity, just as they did with the huawei models, that were all dual-sim.

Oh wow had no idea, thank you for the heads up. I have always wondered why Samsung have the option for either single or dual sim when buying direct from their site, particularly as they are the same price.

Xperia 1ii Variants and Regions

Hi all
I've used this website for years off and on but always reading, never commenting (so far as I can rememeber) and I thought this would be the best place to ask a question.
I am going to purchase this phone as it's been a long while since I last bought one (still using the Z5 Premium Dual) and I need to upgrade. I bought my current Z5 from a UK website that specialised in importing HK phones (but they are no longer trading). I have to say I think it's the first Sony release where I believe that they have addressed most of the issues of anything released after mine, and seem to have got it more or less right, plus made advancements in it's features (Photo Pro, Cinema Pro, etc).
But having a dual sim phone for all these years, I really want to buy the dual sim variant, the only problem is I cannot find enough concrete information to establish which variant is the model I need to buy and then, where from?
So far I've looked at all the US retailers and it's not plain to see as some advertise it as dual sim when its single sim hybrid. I've spoken to both Sony in th UK and US and advice is limited as they only really know about their own products. (Also, the US version(s) apparently do not support 5G and I'm not sure if that means their 5G, or that it would work when here straight out of the box or would require flashing. I don't want to spend that kind of money trying to see).
The Japanese versions are different still as they have their own model numbers depending on the carriers or retailers (I think from research) so I've looked at the Hong Kong site and the only version that they seem to sell directly is the single sim hybrid version which is the same as Europe.
Can anyone here please provide any further details of which model is the dual sim plus SD card version (if there is in fact one) and a link to where they found out.
The versions I know (from xperiablog.net) are:
- XQ-AT51 (I believe think is the single sim hydrid version)
- XQ-AT52 (I think this may be a dual sim plus SD card model but not sure)
- XQ-AT72 (I think this may be a dual sim plus SD card model but not sure)
- SO-51A (NTT docomo – Japanese carrier)
- SOG01 (au by KDDI – Japanese carrier)
The difference between the 52 and 72 variants may simply be the name for different regions but I'm sure that one is classed as the dual sim global version, which would be the version to go for. It would be grat to know the differences too.
If anyone can help with the any of the above, I would be extreme;y grateful.
There is also the time element as if I can't get the dual sim for any reason, I'll have to go purchase here and then I might as well take advantage of the pre-order offer of the free headphones.
Many thanks.

Confirmed XQ-AT52 is a dual-sim version in Taiwan.

I think most people are importing to the UK from wandamobile:
https://www.wondamobile.com/
They ship from HK so you will get the HK/Taiwan dual sim model (XQ-AT52)

I have listed support 4G and 5G Carrier Aggregation and Dual Connectivity (ENDC) combinations of Global XG-AT51 model: https://cacombos.com/device?model=XQ-AT51

may the XQ-AT72 is the Dual Sim version with 256Gb storage

That's the XQ-AT52. The 128 GB storage versions are the Japanese ones starting SO.
Maybe the XQ-AT72 is the Xperia Pro?
