Yes, you can pay for Spotify using Airtel in certain regions. Specifically, Airtel subscribers in Bangladesh can subscribe to Spotify Premium by using their mobile balance. The process involves selecting the "Pay by mobile" option during the subscription process, which allows the charge to be added directly to your Airtel bill.
However, for Airtel customers in other regions, including Nigeria, the Spotify payment via Airtel is not possible. It's recommended to check the specific payment methods available in your country by visiting the Spotify Premium page and selecting a plan. This will display all the payment options applicable to your location, including whether mobile payments are supported.
