In the last two weeks, since Jan's security update, my S22 Ultra 5G is presenting a very poor mobile reception. It constantly swaps between 5G and 4G. During the swap, the device loses the internet connection. In the past, my solution is to change the network setting to 4G but now, the device is even unable to stay at 4G for most of the time. It drops to 3G or H straight away.
I've tried everything I can, including all types of resetting, but the problem persists. I tried to use another sim card which works perfectly on a different device, but the problem remains the same. So I highly suspect this is nothing related to the Vodafone network.
Hope I can get a solution from here, rather than bringing the device to a service
PS:
Please do not ask me to do any reset or whatsoever, I've done it many times, NOT working!!!
This is purely Samsung S22 issue right from the beginning since it was launched. It's hopeless and frustrating that Samsung didn't fix this issue so far. The only workaround is to keep the 4g mode on rather than 5g to prevent loss of internet connection. Ultimately it's a waste of money to buy a S22 or S23 with 5g features.
I don't think this is the answer as you had adequate connection before the update but somethings to consider..Is the other sim card also Vodafone. If so likely to be the phone rather than Vodafone.
Check Access Point Name settings, go to Settings search APN. Compare what is there to what is found by Googling "Vodafone 5G APN settings" (if you contemplate changes make a 100% accurate hand copy of existing settings including spaces and caps).. note Telstra, as an example, has different APN settings for 5G.
Look at quality of connection by loading Wifi Analyzer. Low - dBm around 40 to 90 is good, 110 is poor.
Go to Connections, tap on Vodafone settings and see under the heading Vodafone the quality of the connection. My Mbps at home is usually 4 or 5 hundred. Where I am right now at this moment is 72. This indicates either poor connection to tower or bandwith suffering by multiple users..
Load app called Aus Phone Towers. Use options to see Vodafone coverage by frequency., 5G, 4G, etc. It is unlike,y the tower has broken tower transmission but you never know,
Google "vodafone wifi calling". Provided you are logged in to a wifi network you can receive phone calls and messages via your broadband instead of celll tower, depending on which is better.
I have exactly the same problem. My S22 Ultra Dual SIM device has the same problems with the two SIM Cards and are different carriers. It's unacceptable. I'm from Brazil by my SM-S908E

I am having the exact same problem with my S22, i.e. phone will not connect to 5G DATA in Australia, especially after been connected to internet via wifi. Go in to any phone shop and they will tell you so. Only fix is to change to 4G in settings. Given that Samsung sells this phone as a 5G phone I think they need to fix this immediately or offer a full refund. Samsung?

Thx Claudette. I have done that. But there seems to be a fundamental design flaw in Samsung's error reporting. The Samsung Member's App doesn't work without a data connection. Pretty hard to report on and diagnose a data connection problem using a routine that requires a data connection!
I am sorry I misunderstood your issue. In that case based on what you've described, I recommend for you to head into your nearest authorised service centre with your proof of purchase so that we can take a closer look into this.
