Tons of Carrier Options
While devices like the Galaxy Note 4 are stuck on select carriers, the Galaxy S5 is available on big name carriers and smaller pre-paid and regional carriers. Having this kind of choice is something we love about this phone.
Picking the right carrier is extremely important as each offers pros and cons. Some will offer better network coverage in the areas you frequent most. Some have excellent customer service, some don't. Some have data plans that fit your needs perfect, some won't.
Major carriers are where you should look first but they're not always your best option. So make sure you poke around before you make a commitment. Even if you wind up on a major carrier, you'll appreciate that you had options.
