Long Battery Life
You can enjoy up to 7 hours of talk time or almost 12 days on standby, eliminating any concerns about running out of battery while traveling. The provided USB-C quick charger ensures that you can quickly recharge and be ready to go again in a short period.

Compact Phone, Big Screen
TU550 is conveniently smaller than many phones. Yet its large 2.8 inch colour screen's intuitive icons, and central tactile menu key, allow quick access to essential features like text and camera.

Handy Camera
If you'd like to take a quick snapshot, just capture a photo using TU550's integrated camera. You can even share these pictures by including them in text messages.

Clear Voice Calls
The TU550 provides excellent call quality in busy environments, thanks to the advanced VoLTE technology enabled by 4G.

Emergency Call Button
If you find yourself in an unfamiliar place, it's reassuring to have support. The one-touch emergency-call button on the back of TU550 is there for you. It even activates handsfree calling as an extra precaution.

Handsfree Calling
Being able to take notes when on a call, or perhaps to share it with someone else is essential. TU550's built-in loudspeaker and special microphone make this possible.

LED Torch
The presence of illuminated keys enables effortless dialing, while a conveniently operated built-in LED torch illuminates your path.

Shock Resistant
Due to its sturdy design, the mobile phone remains safeguarded even when accidentally dropped.

Hearing Aid
The TU550 is specially designed to be compatible with hearing aids and offers independent volume control features, both aimed at improving your phone call experience by enhancing your hearing ability.
