Want to learn more about Galaxy A51?

See more of the world.

It’s all about squeezing more screen onto your mobile. There aren’t many that do it better than Samsung Galaxy A51, with a large 6.5-inch Infinity-U display that covers the front from edge-to-edge, bringing your games, videos and TV shows to life with a clear Full HD+ resolution.

Simple yet elegant design.

Sometimes the simplest solution can be the most elegant one. Samsung Galaxy A51 flaunts a simple and streamlined form, only interrupted by the camera lenses. There’s no other button front or back, not even a fingerprint scanner - that’s integrated onto the screen itself.

Impressive camera setup.

You don’t need to spend a lot to get a lot, seeing as Samsung Galaxy A51 comes wielding a quad camera setup for a wide range of professional-looking photos. The Ultra-Wide Camera has a 123-degree field of vision (like the human eye). The 48-megapixel camera takes bright and clear photos. Then the 5-megapixel Depth Camera allows you to adjust the depth of field for jazzy results. And last but not least, the 5MP macro camera is on hand for your close-ups.

Long lasting battery life.

A big and powerful mobile phone like Samsung A51 needs a battery to match. The 4000mAh unit built into it gives you all the juice you need to for streaming, gaming, messaging and more. Plus, it supports 15W Fast Charging for quickly refuelling when you need it in a hurry.

All pay monthly offers subject to security and credit check. Charges will apply for paper billing. Charges may also apply for non-Direct Debit payment, unless on the EE network. Promo codes cannot be used in conjunction with any other offer. Full Legals.
