TP2 on SERO plan, how best to activate?

[garberfc]

I'm expecting my new TP2 today. It's replacing a Mogul on my SERO 500 plan. I want to maintain my SERO plan and am looking for the best / safest / hassle free means of activating it.

I get a very week cell signal at my home and I think there's a means to activate it via the web.

Should I do it via the website or drive to a location with a good signal and do it with the phone?

If done through the website should I wait to power up the phone until it's been activate?

TIA,

F
