For unlimited data and minutes it costs £28 per month with an upfront charge of £19, but the first six months are half-price. This same deal is available with 4GB of data, at £20 per month wth six months half-price.
Alternatively, for 30GB of data you'll pay £27 per month, and for 12GB £23 per month, both with the £19 upfront fee.
The Redmi Note 9 Pro, meanwhile, is available in 6GB/64GB (£249) and 6GB/128GB (£269) models, both available on Amazon or at the Mi UK Store.
Value has been synonymous with Xiaomi during its 10-year lifetime, but never at the expense of quality. In recognition of its rapport with consumers the phone maker is now the world's third largest.
The new Redmi Note 9 series brings to the table incredible battery life - the Redmi Note 9S is unbeaten by any other in our lab tests - along with a premium design and features, including a quad-lens camera assembly.
Our testing of Redmi Note 9 suggests its MediaTek chip is not up to quite the same performance, though it still has much to offer.
We'll explore the specifications and differences between the line-up in more detail in the table below.

All three phones in the Redmi Note 9 series support a high-capacity 5,020mAh battery, but only the Pro boosts the 18W wired charging speed to 30W. It also adds NFC support (which is available only in selected markets in the other models), and upgrades both primary and selfie cameras.
The entry Redmi Note 9 keeps the price low with a slightly smaller screen, a MediaTek processor with a lower memory option of 3GB, a rear-mounted fingerprint sensor and a plastic body.
All three are sold with MIUI 11, a custom version of Android 10, but Xiaomi has confirmed that they will receive an update to MIUI 12.
