Public mobile offers plans with both 5G and 4G speeds. You can technically still use a 5G plan with your phone but it will be limited to 4G speeds. Take a look at the plans available and pick one that works best for you. There's usually promotions going on for new customers. The nice thing about public mobile is you can easily change your plan if a better deal becomes available to you.
I don't recommend switching to Rogers. I've had internet from them and they are a pain to deal with.
