4G bands in India

India will auction some new 4G bands at the start of 2021. While purchasing a new mobile, please ensure that the following 4G-bands are supported:

• Band 28 - 700MHz
• Band 20 - 800MHz
• Band 5 - 850MHz
• Band 8 - 900MHz
• Band 3 - 1800MHz
• Band 1 - 2100MHz
• Band 40 - 2300MHz
• Band 41 - 2500MHz

If your phone doesn't support any of the above 4G bands, then to that extent, its network coverage will suffer.
