eSIM — The Modern Option
An eSIM is built into your phone. You load a plan via QR code, no hardware required. You can do it from home before you fly.
- ✅ No physical card to lose or swap
- ✅ Activate instantly from anywhere
- ✅ Keep your UK number active at the same time (dual SIM)
- ✅ Buy and install in minutes online
- ❌ Requires a compatible device (most post-2019 flagships)
- ❌ No calls/SMS on most travel eSIM plans (data-only)
Physical SIM — The Reliable Fallback
A physical SIM card — bought locally at the airport or from a service like Drimsim — works in any unlocked phone regardless of age.
- ✅ Works on any unlocked phone
- ✅ Drimsim's global SIM covers 197 countries
- ✅ Usually includes calls and SMS
- ❌ You need to physically swap SIM cards
- ❌ Lose your UK number access while the travel SIM is in
- ❌ Can't pre-install before travel — need to swap on arrival
Which Should You Choose?
| Your Situation | Best Choice |
|---|---|
| Modern phone, data-only needed | eSIM (Airalo or Saily) |
| Need calls + data abroad | eSIM with number (Yesim) or physical (Drimsim) |
| Older phone, no eSIM support | Physical SIM (Drimsim) |
| Multi-country trip | Regional eSIM or Drimsim global SIM |
| Long-term travel (months) | Drimsim global physical SIM |
Drimsim Does Both: Drimsim is unique in offering both a physical SIM and an eSIM on the same account, covering 197 countries. If you're not sure which option your trip needs, Drimsim is the most flexible choice.
