I called up 1500 today for a change of plan from 590 NU to 849 NU. A nice lady asked me for my cell number, put me on hold for a few minutes, and then gave me a dock-it number. When asked how soon the new plan would be activated, she said 2 days. Hope I start getting 2 Mbps at least by 1st Sep, and then I'll post my speeds.
