1. Check with your mobile provider. Some mobile providers offer Spotify Premium as a free add-on to their plans. If you're not sure if your provider offers this, contact their customer service department.
2. Sign up for a free trial. Spotify offers a 30-day free trial of Spotify Premium. This is a great way to try out the service and see if you like it before committing to a paid subscription.
3. Look for promotional offers. Spotify sometimes runs promotional offers that include free invite codes. These offers can be found on Spotify's website, social media pages, and in email newsletters.
4. Ask a friend who has Spotify. If you know someone who has Spotify, they may be able to give you an invite code.
Once you have an invite code, you can redeem it by following the instructions on Spotify's website.
