A good thing to do after a major software update is to boot into Recovery and Wipe the Cache Partition and reboot.
As for no data, check your APN settings to see if they are still correct for your carrier.
Try toggling Airplane mode on/off as well as Mobile data.
So what happens when you set it to 4G only? Do you lose all connection ("emergency calls only"), or just data doesn't work?
And is data only working for messages, or working generally but you aren't getting 4G? If messages only, do you mean MMS (which on many networks uses a separate APN from regular data) or other message apps (Messenger/WhatsApp/Telegram/etc, which will use the regular data connection)?
Sorry for all of the questions, but a clear understanding of what the problem is is important in order to find a solution. I'd understood from the first post that data wasn't working at all, but it seems that isn't the case, so it might help to have a clear picture of what is and isn't working.
Or clean the Sim card with a clean pencil eraser and reinstall
Edit: Really, not joking.. I do electronics and a clean pencil eraser can't be beaten when it comes to cleaning contacts. Works great on controllers and remotes too.![]()
Ok, that is odd: there's no difference between the data connection used by Snapchat or Spotify and that used for web browsing, so one working and the other not is weird. The ping test results seem abnormal to me, but shouldn't prevent you using data for web browsing: my cellular connection passes ipv4 and ipv6, but the WiFi on the train I'm using to send this (from a web browser) also fails ipv6 (ipv6 is the new version of the internet protocol, but ipv4 is still universally supported and I'd not expect many websites to rely on the extended features of ipv6). Of course diagnostic messages don't always tell the full story, but just at face value this seems odd.
In that same menu what does it say for "preferred network type?". There are some options there that if misconfigured could cause problems (though the basic problem of some things working and some not is still a puzzle to me).
A final thought: have you checked it's the same in different locations? It would be unlucky if there were a problem with your home cell rather than the phone, but I've known such things happen.
LTE/CDMA? I didn't think OnePlus phones supported CDMA (a technology used by Sprint and Verizon in the USA, and a very small number of networks in a couple of other countries, but not used in most of the world). For the record, my Pixel is currently showing LTE/CDMA/UMTS auto (PRL). If you have that setting, maybe give it a go (of course that would be adding 3G to the list, you already have 4G there, but I just find LTE/CDMA a little surprising).
