My previous mobile phone provider was Cricket. Cricket was a good deal, because I had unlimited minutes and unlimited texting to anywhere in the USA for only $50 a month. I really liked knowing that, no matter what, my phone bill would always be $50. The only problem was that the Cricket calling areas in most states are limited to a few metropolitan regions. Since I am now driving a truck all over the country, I thought I’d go with one of the big service providers. I eventually wanted to buy an iPhone so I thought I’d go ahead and go with AT&T who is the exclusive service provider for the iPhone. I wasn’t quite ready to buy the iPhone so I asked if I could use my old Kyocera. They said that it must be unlocked first. Cricket said that they “do not unlock” phones. There are websites that advertise unlocking codes, but I found nothing for my Kyocera Dorado. Since I was going to have to buy a new phone I decided to go ahead and buy an iPhone.
