Only, for some reason, rare in the UK.


The reason is obvious: so many phones are either SIM-locked to one
provider, or are fitted with SIMs on non-rollover tariffs, that the
opportunities for fitting a second true-Pay-as-you-go SIM are quite
limited.

But if what you want to do is service two SIMs that you'd have anyway,
on one bit of hardware, then the opportunities open up a bit. Even on
locked phone because (for example) GiffGaff and Tesco both use O2, and
Virgin/Orange/T-Mobile all share EE.

Yes, some of those brands are a bit long in the tooth, but I've managed
to acquire non-contract SIMs for all of them (although the Orange one
expired recently, probably because I'd not used it enough).

To the extent that in the past at least the same model phone has been
dual SIM as standard on worldwide sale but single-SIM on the UK SKU.


Same headline model, but a different part number.

I just checked on orange.ro, and in their current catalogue they
have 122 dual SIM phones, and only 71 single SIM - to add some
hard facts to my anecdata. (It must be around a decade since I
owned a single-SIM phone, but when I was in the UK it was a
feature I had to search for, now it's more or less standard.
Except for Apple of course, but then that's why I switched away
from iPhone in the first place... I think they can finally do
dual-SIM now provided your carrier supports e-SIM for one of
them, though.)


It's easier to switch SIMs on an iPhone than many others, so it's
possibility for those occasions when one finds a holiday let that
doesn't have coverage. But obviously no good for being able to operate
to on-the-fly.

One of the reasons for having a Virgin second-SIM is it authenticates
Virgin wifi (for those also not on Virgin Cable) on the phone.

I'm on Virgin Mobile, partly for that reason, and find that it generally
fails to connect to the LU hot spots. It's supposed to connect
automatically, but seldom does.

Of course back when 2G phones first came out the SIM was on a card you could
switch cards easily in seconds but presumably that was deemed too convenient
for users whereupon inserting the SIM was changed to require removing the
battery and messing about trying to get some sum postage sized thing into a
tiny slot at an awkward angle. And now with ever shrinking SIM sizes they're
almost impossible to change without tweezers.

Yes, some of those brands are a bit long in the tooth, but I've managed

Since when has buying PAYG SIMs for most networks ever been a problem? You talk
as if they're a rarity.

I'm not sure how many phones ever took the full size SIM.

Commercial considerations killed them off: the idea was that a person
would have a SIM, and be able to share/borrow a phone to use it in.

But the networks wanted to tie people into having their own phone (and
contract) in particular not wanting a phone they'd subsidised being used
with a SIM from a rival network, or even by using up the scraps on a SIM
from their own network.

Hence the extra inconvenience of having to make a phone with such a
large slot in it was actually running counter to their commercial
interests.

for users whereupon inserting the SIM was changed to require removing the
battery and messing about trying to get some sum postage sized thing into a
tiny slot at an awkward angle.


That's more to do with shrinking phone sizes. It doesn't have to be that
bad if there's room for a so-called standard mini-SIM (rather than micro
or nano), especially if the phone has a clip-on battery.

And now with ever shrinking SIM sizes they're
almost impossible to change without tweezers.

Yes, some of those brands are a bit long in the tooth, but I've managed
to acquire non-contract SIMs for all of them (although the Orange one

as if they're a rarity.


Ones where the credit rolls over and you don't have to make a regular
calls to keep them alive, aren't quite as common as you claim. The
networks hate them because they tend to get used in "glovebox" phones
were they have all the costs of maintaining the number and the billing
records, for virtually no revenue.

Then there's a few phones which need a "5v" SIM, and don't work with a
3v one. Those SIMs are getting harder to find (some say that it's only
Pound-shop Orange SIMs these days, although I have a very old T-Mobile
SIM which is compliant).

I think you need the Virgin "wifi-buddy" app running on the phone, but
it's a long time since I tried connecting.

Hoho, it's now called "Virgin Media Connect", and is one of those
Marmite apps with a predominance of 5* and 1* ratings. It's entirely
possible the 1* ratings are because of some fundamental incompatibility
issues, rather than fat-fingered users.

Needs Android 5, apparently, which is why it's not on my phone any more.

Oh, the irony; the reason I bought and am sticking with that phone
(dual-SIM) is the very reason I can't use the second SIM slot for this.

Because that's what the shops charge, and stealing them is a crime.

I've paid as little as 1P for a SIM in Tesco, and both I and the
checkout assistant were surprised (the shelf was marked 99p)

But they've been trained to believe what the till tells them.

That came with some free data for the first month, so not merely a bit
of plastic needing topping up.

Sainsbury's Mobile used to have some offers (their project flopped and
they did desperate stuff to try to kick start it). One of which was to
give people who bought a phone there, a voucher for a £10 top-up. But
the till regarded a £10 SIM [with one month's credit pre-installed] as a
'phone', so they were effectively free.

My Android 9 phone is dual sim.


Active, standby or hybrid? Maybe the Virgin trick doesn't work on a
standby basis, and all the hybrid I've seen today are also standby.

If I add in my requirement for a replaceable battery, 32GB, active
dual-SIM, I think that narrows the field to zero.

Accepting a hybrid dual-SIM doesn't help, unfortunately (with 32GB, I
probably wouldn't need an SD card).

Ahh, POCSAG+ and 8051 microcontrollers with 256 bytes of RAM, how
I miss thee; and yes, while the GSM days were better - much less
incredibly ugly reusing-the-same-buffer-a-dozen
-times-in-different-places, we even had something approximating
malloc/free - wasting good memory on being able to handle a
completely unnecessary feature like changing SIM with the power
on would mean memory not going on something useful. I wrote the
first WAP/WML browser outside the original Unwired Planet
reference implementation (it was still called HDML at the time,
in fact), and fighting against memory constraints was a constant
battle...

The problem was it wasn't very developer "friendly".
we still worked with PROMs and had to physically reprogram them each time we changed the code.


We could at least afford EEPROMs and In-Circuit Emulators. But
they were horrendously unreliable pieces of kit (not least the
flimsy ribbon cables that connected the ICE to where the chip
would have been) that stopped working if someone in the next room
sneezed, so one of my first gigs was building a test framework
that massively improved development productivity. I didn't
emulate the CPU, so native assembly couldn't be tested in it -
fortunately there wasn't much of that about even then - but built
a set of libraries that would allow the entire phone to be
recompiled and run on a Sun Sparc workstation, with all the
hardware devices simulated by mocks. As I recall - and it is
25-odd years ago - I had fun getting even the DMA-accessed
peripherals to emulate right, with no code changes to the phone
source, even if it was bit-banging them - using Sys-V shared
memory segments... (Interrupts were emulated using Unix
signals...)

Writing the mock instances of things like the LCD controller chip
(which I rendered to the workstation screen using X) bug-for-bug
compatible with the hardware ones was genuinely great
fun...

Gloriously happy days.

I'm on Virgin Mobile, partly for that reason, and find that it generally

automatically, but seldom does.

Maybe due to the 'phone rather than the hot spot ? Of two 'phones

I'm not sure how many phones ever took the full size SIM.

Commercial considerations killed them off: the idea was that a
person would have a SIM, and be able to share/borrow a phone to use


But the networks wanted to tie people into having their own phone
(and contract) in particular not wanting a phone they'd subsidised
being used with a SIM from a rival network,

They solved that problem by having phones "network" locked

My "acquired" smart phone still is

Is still what. Locked? That's hardly unusual.


I know

but you seemed not to understand it as the solution to people "sharing"
phones by swapping SIMs in/out


Do keep up: "[Opportunities open up] Even on a locked phone because
(for example) GiffGaff and Tesco both use O2, and Virgin/Orange/T-Mobile
all share EE."

O2 locking also seems to die eventually by around 18-24 months but it
might depend on whether or not a 'phone was originally purchased
outright.

One of the reasons for having a Virgin second-SIM is it authenticates
Virgin wifi (for those also not on Virgin Cable) on the phone.

I'm on Virgin Mobile, partly for that reason, and find that it generally
fails to connect to the LU hot spots. It's supposed to connect
automatically, but seldom does.

Maybe due to the 'phone rather than the hot spot ? Of two 'phones
which I use, one needs to log on to LU/Virgin and The Cloud at
stations the first time it is used there each day while the other
seems to do so automatically. IIRC there is a setting in the murkier
depths of the WiFi setup which only exists on one of them.


I've probably not investigated enough. I just don't spend long enough
waiting in deep Tube stations to have much use or need for the capability.
Above ground, I just use 4G data.

I don't think those phones have field replaceable batteries in the sense
that Roland meant? Few modern phones do.

I prefer the rear fingerprint sensor. It works well, without stealing
screen space. It's just very natural to pick up the phone with your index
finger on the sensor.

Yes, they do. Mine certainly does, anyway, and looking at the spec
(and a bit of additional Googling) for the newer one suggests it does,
too. You do have to take the rear case off to access the battery, so
it's not as simple as just shoving it into a slot or clipping it on
like you used to do with the pre-smartphone bricks. But the case just
clips on and can be removed with your fingernails if they're robust
enough (and with a small piece of plastic or a small screwdriver if
they're not).

More generally, Moto appears to have deliberately chosen to target
this kind of use case. I came across them when I asked a similar
question to Roland's in another place, and was given Moto as a
recommendation. All of their phones have simple, clip-on cases that
are easily removed to reveal a plug-in replaceable battery (no screws
or other tools needed), and the dual-sim versions are not only active
dual-sim but also have the SD slot separately to the sim slots (so you
don't have to choose between a second sim and an SD card, unlike some
phones). Their version of Android is also pretty close to vanilla,
again unlike the heavily customised version found in phones from some
other popular suppliers.

The downside is that, for a mid-priced phone, they're not usually the
top performers when it comes to camera quality, processor power, etc.
So if that sort of thing matters, you can often find better value for
money elsewhere. But they're perfectly good enough for most purposes
unless you do want to push the envelope. And I find the flexibility
(particularly the active dual-sim, which is the reason I bought one in
the first place) more than outweighs the fact that the camera doesn't
come with bragging rights on Instagram.

I suppose it's worth trying. It's just that I'm used to it being where

Yes, I also have a Moto phone, and it's a good all-rounder, but it had
never occurred to me to try and open the case, with its camera and
fingerprint sensor. And, indeed, it's not user-replaceable:

https://support.motorola.com/uk/en/products/cell-phones/moto-g-family/moto-g6-play/documents/MS126899

The same seems to be true of the G7 range. Maybe only the older (up to G5)
Moto models have user-replaceable batteries?

http://motorola-global-en-roe.custhelp.com/app/answers/detail/a_id/135919/~/can-i-replace-the-battery-in-my-moto-g7%3F

The camera in my phone is quite basic, but I don't care as I seldom use it.
I'm normally carrying a much better 'proper' camera.

It soon becomes natural, and the bigger screen is welcome.

It's the same with my new iPad Pro: I was dubious about facial recognition
rather than the touch ID built into the now-gone Home button, but I soon
adapted to it. I now welcome the larger screen instead.

Only, for some reason, rare in the UK.


The reason is obvious: so many phones are either SIM-locked to one
provider, or are fitted with SIMs on non-rollover tariffs, that the
opportunities for fitting a second true-Pay-as-you-go SIM are quite
limited.



I was quite surprised to find the DORO 2404 granny phone that was sold in

Orange had several innovative features, because it was really a product
aimed at SMEs, to use as a combined cordless PABX at the office, and
mobile when in the field. But with changes in marketing perspective (and
of course network ownership), most of them rotted away.

Which is why I included the words “most circumstances “ rather than
stopping at “pointless.â€

Another example would be a phone shared between two family members who wish
to share a phone but have their own contact number and list of contacts for
when they left home.
But that now basic cellphones are so cheap compared to 20 years ago the
convenience of having one each
available all the time has diminished that method of use.
My use of dual sims was with a work issued Nokia 6310i , I think it used an
adapter that clipped between the phone and battery but it was so long ago I
cannot remember for sure.
The firm wasn’t too bad about allowing limited and reasonable personal use
such as phoning home if delayed or even order a pizza to be collected on
the way back, but I preferred the freedom of being able to use my own
resources without restriction. There were also concerns that too much free
private use of a works phone
would attract the attention of the revenue men and be taxed as benefit in
kind.

My SIM was from Virgin on some sort of pay as you go / contract hybrid
that I cannot remember the name of but I think Roland Perry has mentioned
in the past.
The phone that came with it was actually more featured than the 6310 in
that it had a camera and colour screen and used the Symbian OS for features
making it vaguely intelligent rather than smart.

Using its SIM in the 6310 saved on the pocket clutter by not having to
carry two phones or more usefully the installed hands free car kit which
was tailored for the Nokia 6310 via a hard wired cradle could be used for
my personal number.
Now days the advent of blue tooth means using multiple phones on the same
in car hands free equipment
has also made the requirement to do that obsolete .

iirc they call that "pay monthly". It's a bit like a post-payment PAYG
account, with no ongoing commitment such as you'd have with a classic
contract.

My only remaining Virgin SIM is classic pre-pay PAYG, and I think one of
the disadvantages of that was the roaming charges were very high,
whereas the "Pay Monthly" roaming was cheaper than most contract phones,
at least to begin with back in the day.

Because of my lifestyle at the time, the majority of my mobile calls
were made while I was abroad. (When in the UK, I had landlines at home
and in the office, and the railway commute was largely a long thin
not-spot).
