Best eSIMs I Use as a Full-Time Traveller

As a frequent traveler, I used to buy a new SIM card in each country. It was time-consuming, and I would lose access to my main UK number. Now, with eSIMs, I can:

How to Choose the Best eSIM for Your 2025 Trip

Check Device Compatibility
Not all phones support eSIMs. Check if your device is compatible by dialing *#06# or visiting the Yesim website for a list of supported Apple and Android devices.
Match Your Travel Needs
- Short Trips: Yesim, Nomad or Airalo for affordable, small data plans.
- Long Stays: Yesim or Holafly for unlimited data.
- Multi-Country Travel: Yesim or Airalo for global or regional coverage.
- Business Needs: Yesim, Ubigi for hotspot and high-speed data.
Understand Data Plans
- Daily Plans: Great for short visits (e.g., 1GB/day for a weekend in Athens).
- Weekly/Monthly Plans: Ideal for longer trips (e.g., 10GB for a month in Greece).
- Unlimited Plans: Best for heavy users, but check fair usage policies (e.g., Yesim may reduce speed after high data use).
Tips for UK Tourists Using eSIMs in 2025
- Activate Before Travel: Download your eSIM at home to ensure it works.

Why Yesim Stands Out for International Travel

Yesim is a top pick for 2025 due to its global coverage, easy setup, and flexible plans. With 24/7 support (6-minute response time), a free iOS VPN, and Ycoins rewards for referrals, it’s perfect for UK tourists. You can pay for plans using Ycoins, which convert to your currency (e.g., pounds), and extend plans easily via the app. Unlike traditional roaming, Yesim has no contracts and charges only for data used.
