Tips for Attending the Biggest Music Festivals

Once you’ve chosen a festival, let’s discuss how to maximise your experience.

  1. Book your tickets ASAP: If you intend to go to any major musical events like the ones on our list, it’s best to book your tickets early and before they’re sold out.
  2. Take care of your accommodations: Depending on your budget, see if it best suits you to go with budget-friendly camping, high-end luxury hotels, or something in between.
  3. Pack smart: You don’t need to take everything with you—just focus on the essentials. Think comfortable shoes, hydration packs, and festival must-haves from your what to pack list.

How to Stay Connected at Festivals Without High Roaming Fees

While attending such festivals, you’ll be relying a lot on your phone and data, which could make your phone bill skyrocket. Especially if you’re travelling abroad and want to avoid high roaming charges, you’ll need a sustainable option to assist with navigation, contactless payments, and sharing experiences without incurring significant costs.

One of these options is to use eSIMs. They’ll save you from the hassle of having to physically swap out SIM cards. Plus, they’re much more cost-effective. All you need to do is find the best eSIM plans for festival travellers and stay connected with affordable mobile data.
