Hi, thanks for your reply.  As I mentioned the link suggests I have good coverage. My wife's exact same phone, she is with O2, shows the 5g symbol, whereas mine shows 4g. In network options, preferred network type is 5g,4g,3g,2g. 

The wife's phone has a '5g preferred' option. I tested speed test on both phones and mine was quicker for download and upload so not too concerned 

Hey there ​@fredodonnell, sorry to hear that. What’s your full postcode please?

Thanks,

Tyler

My postcode is RM15 6qu

That postcode on this link states

https://www.three.co.uk/content/experience-fragments/threedigital/uk/en/site/mvno/network-status-checker/idmobile.html

We're fixing an issue in this area at the moment and aim to have things back up-and-running as soon as possible.

We're sorry for any disruption this may cause and will add any further updates here.

But using the same postcode in this

https://www.three.co.uk/content/experience-fragments/threedigital/uk/en/site/mvno/coverage-checker/idmobile.html

(you need to toggle from the default of 4G to 5G)

shows a very patchy 5G signal

That would explain the poor 5G

Appreciate your help. This is the same excuse that I heard from O2 for weeks that there was a problem with the nearby mast. However with O2 I had no 4G signal and with ID mobile I've got great 4G signal. But no 5G. And yet my wife who has the same phone as I and is with O2 gets 5G. What the devil is going on

No problem Fred

I have to admit O2 (and Tesco in my case) gave me a right run around too. Although in my case I had issues for years here. It just got to the point of being virtually unusable, hence coming to iD. And those links I posted don’t give us the answer (and truth for that matter). Other providers checkers will highlight things like congestion, if things are being upgraded and more importantly an estimated time for the works to be completed by. I must admit the O2 checker was good as I could put my mobile number into it and it gave me regular updates - even if it was the same “fault” at least it sent me the info rather than me chasing after it.

Okay, so you could see what happens if you put your wife’s SIM in your phone, as in does your phone show good and usable 5G.

The problem between O2 and iD (iD are a MVNO using 3UK) is that neither share the same infrastructure. But if you wanted to try another known to be good on 5G SIM at least you could rule the phone out. If you do decide to have a tinker, I would highly recommend switching the phones off before ejecting the SIMs.

What the devil is going on

IMHO it’s simply a case the 5G on iD (via 3UK) isn’t ready for permanent use, hence the areas of white showing on the image I posted for your area (showing the result for 5G).

Thank you ​@fredodonnell 

Please keep an eye on the coverage checker for updates on the issue. 

If you are still having the problem in a weeks time, please get in touch either here or via Live Chat/X(Twitter)/Facebook and we will be happy to look in to this further for you.
