| App | Highlights | Why It’s Great |
|---|---|---|

Things to Consider Before You Buy a Global Digital SIM
- Compare global vs. regional plans: If you are hopping around continents, a global plan such as Airalo Discover Global could be a time-saving option.
- Watch the validity period: Short trips? Go for 7-day packs. Long-term stays? 30-day or unlimited plans make more sense.
- Unlimited ≠ , truly unlimited: “Fair usage” limits do exist, particularly with Holafly. Always check speed limits.
- Use Wi-Fi when possible: eSIM data is valuable – keep it for maps, rides, and messaging.
- Keep the physical SIM active (if necessary): It helps with OTPs, roaming texts, or local contacts.
