Most people want to pick the coolest phone they can find and then choose
a service plan. However, that course often does not work well, since not
every phone works with every wireless network.
First-time Buyers and General Users
For a first-time user, it is better to choose your plan first, then the
phone. Because choosing the wrong plan can cost you extra money each month,
while the phone is a one-time decision. In addition, most carriers offer
a full range of phones for each service plan, from inexpensive to full-featured.
Unless you have your heart set on a specific, hot new phone, go for the
plan first.
Wireless systems in the USA (unlike Europe and Asia) are not compatible
with one another. This means that a Sprint PCS phone, for example, won't
be compatible with VoiceStream Wireless or AT&T Wireless service.
Even if you just want to switch carriers, you will probably need to buy
a new phone.
Experienced Users
For experienced users and high-tech junkies, you can start from chooing
your favorite cellular phone. Based on your phone, you may choose you
applicable rate plans, but first-time buyers may find this harder.
