I was only the daily plan for 9 months so I can answer this
With the daily plans the $0.99 cent or $1.99 is only taken out when you make a phone call. It does not matter if you call someone with a Verizon phone you will still be charged because you made a phone call. The $1.99 or $0.99 applies to phone phone calls only and it is a daily charge, and is only activated when you make a phone call.
If you have a text bundle you will only have the $10 taken out of your account every month and there is no charge for texting unless you go over your texting limit. So if you use up the 250 other texts then you will be charged.
