Hi, I have been using the 29.95 plan with page plus for a couple of years. Anywhere Verizon works, this plan will work well. Look at the verizon coverage map and see if it will work for your area of Florida.
There are no extra charges or taxes. I actually pay LESS than 29.95 per month because I buy the pageplus refills online at callingmart and I use a discount code. This month I can purchase at 5% off.
I recommend pageplus wholeheartedly. I have all three kids on it and it is very easy. Think of it as generic Verizon. You can pick a different plan every month if you need to. You can also add a small cash balance to your account if you think you are going to run out of data. You can buy a new phone off ebay anytime you like and use it on the plan. It is supereasy to program a phone, takes about five minutes. The only catch is that you need to use a 3G phone. If you are going to use a 4G phone you have to get the phone "flashed" over to pageplus, and this is something most people will pay for.
PM me if you have any questions!
