I had FiOS installed yesterday at the base speeds for my area of 15/5. I went online roughly 5 minutes later on MyVerizon and put the order in for 25/25. What kind of ETA am I looking at before I see the upgraded speed? I would have loved to been able to enjoy it over the weekend.
Typically, once an order is placed on the web site, it will be processed by the end of the next business day. So chances are that if you ordered it on Saturday, you will be upgraded by the end of the business day Monday.
