I have an S8 now and would like to upgrade to an S22. When I look at doing that it wants me to upgrade my data plan to 5G which costs more. I would like to buy my phone and keep the data plan I have now. I know it does not have 5g but really don't care about the speed. Not worth the price. I mostly use my phone at home on my home network, so I don't need the over price 5g. So, I would like to buy an S22 off the internet and just switch out my sim card. would that work or would they force me to get 5g?
