Switch from Sonic to att self install
Hi im switching from sonic, which uses the at and t network to to at and t fiber. I already have a ont box. At and t called and said the new box they are sending (self install) wont work as we already have active service at the address. I have to cancel sonic for the box to work. Sonic ends on june 4th can I cancel and install the box on june 4th? my service for at and t is starting on may 26th. At and t said call may 26 to cancel sonic and they will right away automatically be notified and the box will work. Is this true?,
I don't want to get stuck without internet. The billing is starting for at and t may 26th......whats the best way to make sure my router will activate with at and t when I install it? What is the way to have the box work on may 26th I don't really need to wait till the 4th as at and t will charge me anyways I think on the 26th. Basically what issues with activation will I deal with, should I tell sonic to cancel the same day the 26th, or should I cancel at the end of billing cycle on the 4th? What's the way to do this that my box will activate on the 26th? Thanks.
