If you own your own phone, Tracfone can be a good deal as they ride on the ATT or Verizon networks. One of the Bosses at work bought his phone off Amazon or ebay and got the sim card from Tracfone. Tracfone has list of phone compatible with their network on their website. He buys his plan buy the year for like $120 talk, text unlimited data.
My name is Melissa and I've used Verizion for 20 years.
I have two phones with them. I have had Verizon since I found driving all over God's green creation that they have or had the best service. When my 2 years was up on my phones I went into the store and they reduced my bill by $25 per phone since their contracts were up. Also need to check with them from time to time if they have new plans at better prices or if the data prices have dropped. I once doubled my data for the same price.
Bottom lines is we have portable computers which have phone apps on them. These little computers cost around $600-$800 and unless they financed them most people could not afford a "new phone". Like the printer people, they have figured out the real money is in the data plans. So they are starting to have people pay for the phone outright and offer bigger data plans at better deals.
We use Samsung phones at work for driver's logs, I prefer the Droids and my daughter prefers her iPhones. That's just personal choice.
Unlocking a phone (able to use on any network) use to be illegal but it no longer is. Personally, I like to deal with people face to face.
