Quick Top Picks
What Is an eSIM?
An eSIM (embedded SIM) is a digital SIM card built into your phone that lets you activate a cellular plan without a physical SIM card. Instead of buying a local SIM at the airport or paying expensive roaming fees, you can purchase and activate an eSIM plan online before you travel.
eSIM vs Physical SIM vs Roaming:
- eSIM: Digital, instant activation, no physical card needed, keep your home number active
- Physical SIM: Requires airport purchase, swapping cards, risk of losing your home SIM
- Roaming: Convenient but extremely expensive ($10-15/day typical)
For most travelers, eSIMs offer the best balance of convenience, cost, and reliability. Learn more about staying safe while traveling in our travel safety guide.

How to Set Up Your eSIM Before Flying
Follow these steps to ensure you have internet the moment you land:
Choose Your Destination Plan
Select the country or region you're visiting. For multi-country trips, choose a regional plan (like Europe or Asia) to avoid buying multiple eSIMs.
Purchase and Install Before Departure
Buy your eSIM at least 24 hours before your flight. Install it via QR code or app while you still have WiFi at home. This ensures everything is ready before you travel.
Keep Your Home Number Active
Your eSIM works alongside your regular SIM. You can still receive calls and texts on your home number while using the eSIM for data. Perfect for keeping WhatsApp and iMessage working.
Activate When You Land
Turn on your eSIM data when you arrive. Most eSIMs activate automatically when they detect the local network. You'll have internet within minutes of landing.
Pro Tip: Add your eSIM to your travel packing checklist so you don't forget to install it before departure. Installing at the airport with spotty WiFi is frustrating!
Common eSIM Mistakes to Avoid
❌ Buying Airport SIM Cards
Airport SIM cards are notoriously overpriced and often come with hidden fees. You'll pay 3-5x more than an eSIM for worse coverage. Plus, you risk losing your home SIM card when swapping.
❌ Waiting Until You Land to Activate
Install your eSIM before you fly. Airport WiFi is often slow or unreliable, making installation frustrating. Having your eSIM ready means you'll have internet the moment you land.
❌ Assuming "Unlimited" Means Unlimited
Some providers advertise "unlimited" but have daily caps or throttling after certain usage. Read the fine print. Holafly is one of the few with truly unlimited data.
❌ Not Checking Phone Compatibility
Not all phones support eSIM. Check your phone's compatibility before purchasing. Most iPhones from XS onwards and recent Android flagships support eSIM. Learn more in our travel safety guide.
