They will waive the surcharges and have 100% real unlimited until it gets saturated, and then they will stop waiving the fees and go back to limited. Hopefully a bit higher of depri tiers, but I'm sure it will go back to how it is now eventually.
Why would carriers do that? I mean are you like not gonna use them?
Imo it will be like 4G when it first was rolled out. In the beginning, there will be a premium for accessing 5G speeds. Higher tier post paid plans would probably include 5G, while lower tiers will have it as an optional add on. On prepaid, it will be optional for an extra fee. Once 5G access points are more universal, then carriers would start "discounting" those fees. Imo due to the limited access to 5G thanks to their really short range, it would stay exclusive for a while.
