Internet Basic 6 or Internet 12 from Internet Basic 3, without tech. visit? Possible?
I currently have Internet Basic 3. NVG599 Gateway. Looking to upgrade speed. I understand a tech visit is required to switch to one of the fiber plans (Internet 18 & higher). What I would like to know is if it is possible to upgrade to any of the intermediate tiers without a tech visit. Internet Basic 6 and Internet 12 show as available options through the ATT web portal, however both indicate a site visit is required. I believe they are both ADSL2+ (correct?), and wonder if a tech visit is actually necessary.
