5G on Xiaomi but not on Pixel 7

[GrahamL0995]

I switched my number yesterday after trying out the sim in a spare Xiaomi phone. 5g was available immediately. Now with the sim in my Pixel 7 there's no 5g network showing up, only LTE. Any solution?

I had drawn the same conclusion based on trying a colleague's P8 Pro and after dayler mentioned PLMN back/whitelists. It would seem that there are a plethora of support posts from folks in countries that Google does not support 5G in having the same issue. In this case, it seems Google doesn't support 48 (yet) but they do officially list Three, Eir, and Vodafone (see: https://pixel.withgoogle.com/5G/). So if I had to guess, it'll just take time, as I know for a fact that GoMo is supported, in spite of it not being officially listed (probably because like 48 it's an MVNO). Maybe if enough of us hassle Google, they'll get on it!

I think GoMo may work because it uses an eir PLMN (MCC/MNC) - namely 272/03 as far as I know - that is allowed by the Pixel firmware/configuration but they don't allow the Liffey Telecom (Tesco/48) one (272/11)?

I think you've just got to the bones of it. It makes PERFECT sense.

How long have Tesco offered 5G for on their top plan?

Sorry, I don't know.

I've seen reports of other Google Pixel phones using PLMN (Private Land Mobile Network) white and/or black lists to tell the handset what carriers it can/cannot connect to. Maybe the Pixel 7 uses these too? It doesn't look easy for a user to change these (needs root access and some hacking where it's even possible). Has anybody contacted Google support to ask them if it's a limitation of the Pixel 7 that it can't connect to the 48 network? Note that even if it can connect to the Three network the 48 MVNO virtual network will appear to the phone as a completely different network.

I don't know if this is relevant:

There are a few mentions of Ireland in that issue and one of eir but nothing specifically about 48.

[DaveO4704]

Might contact Google, as you've suggested. I have no problem in rooting to test it out but I try to use the stock firmwares where possible nowadays. It's a can of worms, to be honest. Back in the early '10s I always had phones that were out of support and used to dabble a lot.

[dalyer]

I noticed some chat about the possibility of hacking this on XDA but didn't read it in detail.

Seems possible that any ire being directed at 48 here may be better directed at Google - not that it looks like they'll drop everything to fix it judging by the issue/bug that I linked to.

But it's still not 100% clear why this issue arises.

And I totally agree that the reply that you previously received from 48 support was not at all helpful or even relevant.

Thanks for the insight yesterday, pal!

After I dug around, it would seem that there are a plethora of support posts from folks in countries that Google does not support 5G in having the same issue.

I have the same issue on a Pixel 7A. No 5G at all. (Have 5G on a Galaxy S24)

Three had the same issue a few years back when they launched 5G, Pixels would not pick up 5G and Three had to work with Google apparently to enable support. I guess the same thing here will need to happen but whether 48/Three will bother will be the utlimate question
