Among the spam sent to my mobile phone by O2 I have discovered a warning
that they will be switching off 3G at the end of 2025. Although it is
still working at the moment, I thought it would be expedient to replace
my basic Alcatel 3G 'phone with something equivalent that worked on 4G.
I bought an IMO Dash 4G, which seemed to meet my needs - but when I went
to transfer the SIM card I discovered that it was too big and I needed a
mini SIM to fit that model. This afternoon I visited an O2 shop and
they fitted a replacement SIM, which they loaded with my previous
address list.
So far, so good.
When I got home, I made a test 'phone call to a friend's mobile 'phone;
the audio was dreadful with clipped leading sylables and mushy sound
that was so bad we hardly exchanged a single sentence without having to
ask for a repeat of some of the words. The signal strength was showing maximum on both our 'phones at the time.
I then tried calling my home landline number and tested for transmission
in both directions. The result was the same: ordinary speech was
partially inintelligible with syllable-clipping and gaps in the sound.
The problem is that I have changed two things at once: Alcatel >> IMO
and 3G >> 4G. Should I blame the 'phone or O2 ?

Blame the phone - never heard of IMO Dash.
Two options:
Get a Nokia 110 4G - shopping around you should be able to get one for
less than -u40 (-u33.35 from Amazon ATM). Be aware that it does not come
with a charger but if you have such then you will only need a USB-C
cable to charge it;
Visit your local Computer Exchange or check them on line (uk.webuy.com)
and find something to suit there. Their pricing is very good and you get
a 5-year warranty with it. They have a branch in Bath (Abbeygate Street
down the side of M&S.)
Alternatively you can buy by post and return it
if not suitable or as advertised. Grade A means essentially new and
boxed; grade B means good condition but probably unboxed and possibly a
small mark or two; grade C - avoid!

Does the phone know your wifi password? Could it be 'wifi calling' struggling with your internet connection? Try turning off wifi and
re-making a test call.
Another possibility is the IMO doesn't support VoLTE - 'Voice over LTE' (basically VOIP over 4G) and it's falling back to the older 2G network for voice, even though it might have a perfect 4G data connection. Perhaps 2G reception is poor where you are? As O2 are turning off 3G they're also turning down the wick on 2G which might mean worse connections for phones (but which won't bother smart meters, the current real customer paying for 2G). A lot of older phones either don't support VoLTE or the network won't enable it for phones they haven't specifically authorised.
I suggest taking it to an O2 shop and asking them. If you want a basic
phone they may sell you something like a HMD 105 4G (HMD is the new name for Nokia; the Nokia branded phones are older versions) which supports VoLTE on their network.
The O2 shop is a long distance away but I may finish up doing that.

The third replacement attempt, a Nokia 235 4G (2024), has just arrived. Exactly like the Alcatel, turning off the keypad bleeps turns off the
ring tone, so I won't be able to hear when there are incoming calls.
!!!!!!!

Are you sure you have the right setting? Usually 'volume' controls all
tones, and if you put the phone in silent then you also silence the keypad. But there's typically another setting for keypad tones alone.
The 'user guide' is only 16 pages excluding legalese and doesn't explain the settings, but it appears to have multiple profiles (Menu > Settings > Profiles) and on other Nokias you set keypad tones inside profile settings.

Thanks for that. I've eventually managed to discover those other
options, despite the menus in the manual not corresponding to those in
the 'phone, so the main problem is solved.
A relatively minor matter still remaining is the actual ringtone. I
have been using a customised ringtone for the last 9 years, so that I
can recognise my own 'phone even if it rings in a noisy place and is
set to low volume. The ringtone is on a MicroSD card in .mp3 format
and is about 1MB in size.
The ringtone menu offers me a choice of my own sound file but claims
.mp3 is an unrecognised file format. I can also opt to just play the
file as if it were entertainment that I wanted to listen to. Again,
it refuses with "Unrecognised file format".
Surely they can't have failed to include an .mp3 reader - if they
have, what sense is there in having a slot for a MicroSD card, when
most of what people would record on it couldn't be played?

I can't answer that, but can't you just convert the .mp3 file to one
that is recognised? Handbrake is good at that, also try VLC.

It appears from some sources that .mp3 should be a recognised format.
I suspect thre have been several versions of this 'phone but they
aren't documented correctly. The hardware is fine but the software
is a mess.

So you either change the 'phone or use a format that it recognises.
My Nokia and my car both speak Bluetooth, and they will Pair, but come
back the next day, and they will see each other, but will have a
Failure to Communicate until the process is restarted from scratch.

I have that problem with USB sticks in my car which may be relevant
to you Davey.
In all of our previous cars (VAG) the power to the stick goes off
with the ignition, but on our Karoq the USB-C sockets in the dash are permanently live. Ergo when the 'Infotainment' unit comes to life by
hand or by ignition the unit fails to see the stick or rather it sees
the stick but cannot find and contents. De-power the stick for five
seconds, plug it back in and it works. Could this relate to your
issue.

Very odd.
Maybe the fie is corrupt in a way that the old phone did not bother about

I am sure that have not failed. It is some quirk of that particular file.
Try converting it to .wav, and back again to MP3

Another thought: is it an unusual sample and/or data rate? Not sure
about anything as sophisticated as (even a simple) 'phone, but I've had
(I think) hardware MP3 players that won't hamdle certain combinations there.
Just for curiosity - I did have (I can't find it now) one mp3 file that played quite satisfactorily quality-wise (on a computer, anyway),
despite having a data rate of 8 kbps; it was of an alpine horn solo,
which might be why - single notes, a fairly simple waveform, slow
changes. (If you try to play something fast on an alphorn, you'll have finished before the sound comes out the other end ...)
I doubted if anyone else would have a ringtone
remotely like it, so I wouldn't be confused by other people's 'phones ringing.
This is a piano rendition of a moderate speed waltz ("Secrets" by
Charles. Ancliffe) - I chose it because it was a played by a friend for
a CD that was never issued - it seemed a shame to waste such a lovely >reocording - and because I doubted if anyone else would have a ringtone >remotely like it, so I wouldn't be confused by other people's 'phones >ringing.
I queried this with Motorola, and the upshot was their
declaration:
"Dear Customer
This is just the way the unit was designed.
When you select a Ringer Id for anyone, then whenever they send
you a TXT, Fax, email or call you, then the Ringer ID you have
selected for that person, will go off."
