5G SIM. Should I change router to 5G?

[Laneysixty8]

Hi everyone. 
I have a 4GEE router that I’m using in a new build on a temporary basis. I’m told by EE that the SIM is on 5G. My download speeds aren’t bad at around 60Mb. Would a 5G router improve this? I believe I have a 100Mb cap on the SIM so I don’t think it’ll go any quicker than that in any case. 
thanks in advance

Do you know anyone with a 5G phone - if so, are you able to run some speed tests using their phone in this new build?

I have an iPhone that runs on 5G. The speeds on that are 130mb average. I’m getting around 50 - 60Mb on the router.
