- Local telecom pricing

4. Real-World Cost Comparison: Airalo vs Physical SIM

📌 Scenario A: Short Trip (1 Week, Multi-Country)
- Airalo Regional eSIM: Suppose you pick a Europe/Asia plan; eSIM might cost, say, $25 for a few GB across several countries. (Based on typical eSIM pricing.) bettersim.com+1
- Physical SIM: Buying a separate local SIM in each country is costly (local SIMs + multiple activations) or you buy tourist SIMs, which might also be expensive. According to BetterSIM, for a 3-day trip in Europe, eSIM wins for convenience and cost. bettersim.com
Verdict: In multi-country short trips, eSIM (Airalo) often saves money and hassle.

- Physical Local SIM: As per Dial91’s data for India, a 2-week tourist SIM plus airport markup cost $14.50 for 3 GB. dial91.com
Verdict: Physical SIM might be slightly cheaper for high data users, but depends heavily on how much data you consume.
📌 Scenario C: Long Stay (1 Month+)

- Physical SIM: Local SIM with a long validity plan often offers far better rates. For example, in India, a long-term SIM plan may cost significantly less per GB than eSIM plans. dial91.com
