What cell phone/cell phone provider do you use or which has been your favorite?  

So I just got a new cell phone/cell phone provider/plan that I LOVE, and it got me thinking, though... that I'm sure that there are ones that I haven't heard of or that I haven't tried that perhaps are better. I just purchased(and purchased the same for my mom) a boost phone for about $99. When I purchased the phone I bought a "re-boost" card for $50. I came home with my phone and my re-boost card, activated my phone over the internet and then used the internet again to re-boost my phone with the card. The plan I picked from boost was the $50 monthly unlimited plan. It doesn't require any credit card information, though you could use your credit card to pay instead if that's what you'd rather do... and you don't have to worry about being tagged to any contracts for a year or two years or however long. With this plan I have unlimited talk(meaning any time of the day or night during the week and weekend), unlimited text(regular texting, picture text and audio text), unlimited direct connect(the walkie talkie feature on the boost phones) and unlimited web usage each month. I thought this was just amazing! Personally, after having used nokia with at&t service, nextel with a contract, and tmobile with a contract at one point and prepaid at another point... and after trying multiple different types of plans with these phones... this phone/provider/plan is most definitely my favorite!
What do you think? Has anyone else heard of this plan from boost? Or do you have another plan or provider and plan that you like more so? Why do you like them? What does your plan consist of for the price?

I just really think that everything included for this boost plan with the price it's at is a great deal.
