hi i need to ask..

currently im a unifi 50mpbs service subscriber paying rm 249/mo. My contract should have ended based on what i see from my account login on their website.

I'd like to downgrade my plan now to just use Unifi Lite 10mbps because i dont see a need for 50mbps speed anymore. Do I need to go unifi to cancel existing subsciption first before reapplying new package? Or i can just downgrade it straight away through phone call?

If i need to terminate current service first , Is there anything that i need to return? the modem and router is it?

Thanks
