Sometimes, it's not what's inside that counts.

Take the Alcatel A5. You won't find cutting-edge features that promise to change your life. No, the A5 is more concerned about accessorizing. Following the lead of the Moto Z phones, the A5 brings three modular accessories that expand how you can use the phone. There's an audio speaker, a battery pack that doubles its life and a case that will, ahem, light up your life. Snap it on and program the LEDs covering the back to light up when you get a notification, modulate with music, or sync to the sound of your voice. Just be warned that it draws power from your battery so go easy on the sparkle if you need your A5 to last through the day.

The A5's guts make it fancier than Alcatel's other two Mobile World Congress announcements, the A3 and U5. The one exception is that the A3 has the most powerful rear camera. The A5's fingerprint sensor is one of its more notable features, but that won't make it into the US version. See below for the full list of the A5's specs, and those of its siblings.

Alcatel did not announce pricing availability. We'll bring you those details when we get them.
