Detailed Breakdown
Free Wi-Fi ($0)
Available: Hotels, cafes, airports, malls Reality check: You're offline between hotspots. No maps, no ride-hailing, no real-time communication. Security risks on public networks. Not a viable primary solution for active travellers.
Best for: Supplementing another data source, not replacing one.
Local SIM Cards ($0.50-8/day)
Cheapest in: India ($0.10-0.30/day), Thailand ($0.70-2/day), Indonesia ($0.50-1.50/day), Vietnam ($0.50-1/day) Most expensive in: Japan ($3-6/day), Switzerland ($4-8/day), Scandinavia ($3-6/day)
Hidden costs:
- Time to find and visit a store (30-60+ minutes)
- Registration (passport, photos, sometimes biometrics)
- Activation delays (24-72 hours in India)
- Premium airport pricing (30-100% markup)
eSIM Plans ($2-10/day)
The sweet spot of cost vs convenience for most travellers. eSIM plans from providers like Roamaly offer:
- Transparent pricing — know exactly what you'll pay before you buy
- No hidden costs — no taxi to a SIM store, no registration fees
- Instant activation — no time wasted
- Multi-country coverage — one plan for multi-stop trips
| Destination | eSIM (1GB/day, 7 days) | eSIM (2GB/day, 7 days) |
|---|---|---|
| Japan | $14-21 | $20-28 |
| Thailand | $10-14 | $14-20 |
| USA | $14-21 | $20-28 |
| Europe (multi) | $20-28 | $25-35 |
| Australia | $14-21 | $20-28 |
Pocket WiFi ($8-15/day)
Once popular, now largely obsolete for solo travellers. The only use case is connecting 5+ devices simultaneously. Add a security deposit ($50-200) and potential replacement fees.
Carrier Roaming ($5-50/day)
The most expensive option. Even with travel passes ($5-15/day), carrier roaming costs 2-5x more than equivalent eSIM plans. Without a pass, charges can be astronomical.
The Best Value Strategy
For most international trips, the optimal approach is:
- Buy an eSIM for primary mobile data (navigation, messaging, ride-hailing)
- Use hotel/cafe Wi-Fi for heavy data tasks (streaming, video calls, backups)
- Download offline content before your trip (maps, music, translation packs)
Money-Saving Tips
- Buy exactly what you need — Roamaly's Day Pass model prevents data waste
- Download offline maps — Google Maps offline uses zero mobile data
- Disable auto-sync — turn off photo backup and app updates over cellular
- Use messaging over calls — WhatsApp messages use a fraction of the data of voice calls
- Connect to Wi-Fi at hotels — save your eSIM data for when you're out exploring
- Monitor usage — check your phone's data usage stats daily
