Yep. Got s22 ultra with vodafone uk. I have no signal at all now at home. Signal jumps randomly between no service, emergency calls only, 4g, 3g, 2g etc when I am out and about. Vodafone have confirmed no issues their end. I have turned on and off airplane mode, reset network settings and switched from an e sim to physical sim. Onto Samsung live chat as we speak. Will let you know what they say. Got a feeling they will blame the network though.🙄
