Welcome to Vodafone Community
I would like to ask 3things regarding the samsung Galaxy s10 plus
1 does it support 4G calling
2 does it support wifi calling
3 does it support 4G+
The phone itself will have the capability, but it also depends on when / whether Vodafone add it to their eligible list of phones _ which I'm confident that they will.
Current Phone > Samsung Note 10+ 5G _256Gb > Model: SM-N976B.
Samsung One Ui / Pie.
Samsung Gear s3 Frontier Watch.
