Best Mobile Service for Reliable Connectivity?

I’m looking to upgrade my mobile phone service and would love some recommendations. With 5G becoming more widespread, I want to ensure I choose a provider that offers the best coverage and speeds. I’m especially interested in how reliable the 5G internet service is, as I need consistent, high-speed internet for both work and streaming on the go. For those who have already made the switch, which provider have you found to be the best for 5G connectivity and overall internet performance? Any advice would be greatly appreciated!
