You may want to speak to a Sales Associate at a retailer that
sells phones so they can qualify you on which phone best suits
your needs and qualifies as a dependable phone for you. The
phone that best suits your needs will be based on which
features on the phone are features that you want and on how
you are looking to use the phone such as internet access,
Bluetooth connectivity, apps, storage capacity, built-in camera,
and a variety of other features that you deem necessary.
Knowing that will help them to recommend which phone will be
the most dependable and best phone for you
