The roll out of 5G in India has been more or less unnoticed by the general consumer. There is the icon on your phone, and at times the speed is better, and that’s all there is to it. However, with Airtel’s Priority Postpaid, you get access to network slicing, which is something only 5G can provide, and it is one of the few things that makes it possible.

Imagine a mobile tower to be a highway. All users share the same highway. When there’s nobody else around, it’s yours alone at 2 am. During peak hours, in an overcrowded concert venue or busy market, everyone competes with a hundred other users on the same highway. Everybody goes slower – the tower isn’t broken, it just can’t handle the load, and there’s no solution to this issue in conventional networks.
With network slicing, the common highway becomes several logical highways that run on the same physical infrastructure. Each slice becomes a virtual network with a dedicated bandwidth and priorities, isolated from all the others. Traffic on one slice doesn’t influence traffic on any other.
The crucial thing about network slicing is that it’s not just about radio configuration of the towers. Virtualisation happens all across the network, right down to the antenna. It is done using software-defined networking and network functions virtualisation.

With Non-Standalone 5G, most operators have rolled out 5G radios attached to a 4G core. This makes the network faster than before; however, the core remains that of a 4G. For network slicing, a 5G Standalone system is required, where the operator has to build a new 5G core to create and manage dynamic network slices in real-time.
For this, you will need a 5G SA-compatible device along with the appropriate software, which will enable you to access Priority Postpaid.
Every single prominent slicing deployment thus far has been in the enterprise space, not consumer-focused. Singtel used a special slice for the 2022 Singapore Grand Prix. Vodafone in the United Kingdom streamed the King’s Coronation over a dedicated public 5G slice. Both T-Mobile and Verizon in the US launched slicing solutions for first responders, while AT&T’s “Turbo” solution, although similar in appearance, is a data prioritisation solution, not a slicing one. Meanwhile, Malaysia’s Maxis utilises slicing for its enterprise users via the Singtel Paragon platform: factories, logistics, industrial IoT.
A slicing solution where an individual subscriber enjoys a guaranteed priority tier in his/her monthly subscription is exceptionally rare around the globe. This is precisely the gap that Airtel is aiming to fill.
When a Priority Postpaid subscriber finds himself/herself at a congested site, all of his/her traffic will be channelled into a reserved slice with guaranteed bandwidth. No other subscriber using the same tower is throttled, but neither do they enjoy the same level of assurance. The effect becomes clear only in congested conditions, when the network is stressed.
However, the catch is that the reach of Airtel’s 5G SA network is still increasing. A slice is only as powerful as the number of SA-enabled towers at your disposal. As both Airtel and Jio (which has adopted a SA-first model and has already been experimenting with slicing since 2024) grow, this becomes standard practice. But for now, Priority Postpaid marks the first time 5G has done something in India that 4G was simply unable to do.
