Why eSIMs Are the Smart Choice for International Travel
With many UK networks scrapping free EU roaming and charging hefty fees for worldwide data, using your regular SIM abroad can lead to shockingly expensive bills. An eSIM (digital SIM) offers a smarter, cheaper alternative—here’s how they work and how much you could save.
Key Benefits of Using an eSIM Abroad
✅ Avoid expensive roaming charges
✅ Connect to local networks for cheaper data
✅ No need to swap physical SIM cards
✅ Pre-purchase before travel & activate instantly
✅ Use multiple eSIMs for multi-country trips
eSIM vs Physical SIM: Which Is Better for Travel?
| Feature | eSIM | Physical Travel SIM |
|---|---|---|
| Setup | Digital (no SIM tray needed) | Requires physical swap |
| Convenience | Buy & install before travel | Must find & buy abroad |
| Flexibility | Multiple eSIMs stored | One SIM at a time |
| Risk | No lost/damaged SIM | Risk of losing original SIM |
| Phone Compatibility | Most newer smartphones | Works on all unlocked phones |
Downside? eSIMs can’t be transferred between devices if your phone dies.
Where to Buy eSIMs & How Much They Cost
Popular eSIM providers include:
-
Maya (Budget-friendly, data-only)
-
Holafly (Unlimited data, pricier)
-
eTravelSIM (Includes phone number)
Cost Comparison: eSIM vs UK Network Roaming (Europe)
| Provider | Cost for 1 Week in EU | Data Allowance |
|---|---|---|
| O2 | £0 (25GB fair usage) | 25GB |
| EE | £15/week | UK allowance |
| Vodafone | £15/8 days | 25GB |
| Three | £14/week | 12GB |
| eSIM (3GB) | £6/week | 3GB |
💡 Most people use ~8GB/month (Ofcom), so 3GB is plenty for a short trip.
