UPNP issues and is there a fix?

Hi I understand that the reason most gamers using t mobile home internet experience high ping is because of the lack of "UpNP" and was wondering if I upgraded to really nice gaming router with upnp enabled it would fix my issues. Or would it not help since the modem t mobile gives you doesn't have upnp

Ping on last provider 0-20

Ping on t mobile 40-60
