Can I switch my internet speed if I already chose 60mbs?

Yes but oyu have to do it before beta ends

Or else you will have to pay the 'normal' price

Yes, but the change won't be in effect until the next billing cycle.

Anyone knows if the change in speed is transparent without any modem change or a visit from the Technician?

Speed change can be done from the website without technician intervention and nor modem change

Ayy Alright thanks guys <3

of course you can switch

Yes you will be able to change you internet speed at any time :) It will become effective during your next billing period. In theory you can edit your speed every month

@Yelena: you are absolutely right :S haha my bad
