Travelling is all about the sights, the food, and of course flexing on social media that you’re on a holiday. But when it comes to staying online, the options can be a bit overwhelming. 

​​It might seem like a no-brainer to save money with public Wi-Fi or a cheap travel eSIM, but here’s the catch: their reliability and security can be hit-or-miss when you’re overseas.

That’s why more travellers are choosing to add roaming to their mobile plan as the safest option. Providers like Singtel even offer tools that automatically block scam links and unsafe networks while you're roaming and on the go

In this article, we’re breaking down the options and costs so you can make a smarter choice for staying connected on your next trip. 

 

Public Wi-Fi and alternative eSIMs = Cheap, but not always safe or reliable

Travellers often start with free public Wi-Fi or cheap third-party eSIMs because they seem like the quickest, most affordable ways to get online abroad. But both options come with trade-offs that aren’t always obvious upfront.

Setup process

  • Public Wi-Fi: Easy to join—tap, connect, done.
  • Third-party eSIMs: Also convenient, but may require manual setup, QR codes, and troubleshooting. If your phone dies or gets damaged, you’ll need to buy and activate a new one.

Considerations to keep in mind

  • Public Wi-Fi networks are usually unsecured, which makes it easy for scammers to intercept your data. 
  • Third-party eSIMs can have inconsistent coverage, restricted app compatibility, or network throttling. And because you don’t always know which network you’re connected to overseas, speeds and stability can vary when you need it most.

Estimated costs

  • Wi-Fi: $0 upfront, but potential losses from scams or identity theft can reach $500–$3,000.
  • eSIMs:
    • $5–$10 for basic data packs, with top-ups adding another $25–$40
    • Hidden costs include time wasted fixing poor connections or activation issues

Takeaway

Wi-Fi and third-party eSIMs may look like great bargains, but the trade-offs like security risks, unstable connections, and hidden costs can outweigh the savings. For travellers who prioritise safety, consistency, and peace of mind, roaming plans with built-in scam protection (like Singtel’s Mobile Protect) are becoming a far more dependable choice.

 

Roaming = The safest and most reliable option

For travellers who value convenience and consistency, roaming is one of the safest ways to stay connected abroad. No hunting for Wi-Fi passwords, no fiddling with QR codes, and no waiting or risking an unreliable SIM card purchase. Everything is managed through your existing mobile plan, simple, seamless, and stress-free.

Setup process:

  • Effortless setup: Once activated, your phone automatically connects to trusted partner networks the moment you land. With Singtel Roaming, you know your connection will work before you even fly.
  • In contrast, alternative eSIMs only reveal their network quality after you arrive.  If something goes wrong, support is often limited or non-existent. Singtel Roaming gives you peace of mind with reliable coverage and dependable assistance.

Considerations to keep in mind:

  • Singtel Roaming stands out because it gives you access to multiple trusted partner networks in the same country, not just one or two random ones. This creates a more stable, seamless experience, even when you move between cities or crowded areas.
  • On top of that, Singtel now includes built-in security as standard in their mobile plans.
    • Mobile Protect is already included for all Singtel 5G+ Priority customers.
    • With UnlimitedRoam and ReadyRoam Monthly, Mobile Protect is free for all users—both locally and overseas. This trial automatically drops after 60 days.
    • That means scam sites, fake links, and malicious QR codes get blocked before they reach you, giving you an extra layer of protection that Wi-Fi and third-party eSIMs simply can’t offer.

Key benefits of Singtel roaming:

  • Auto-connect to trusted networks and widest coverage: Singtel Roaming auto connects you to multiple trusted partner networks in each country, so you don’t need to keep switching or topping up mid-trip. You simply stay connected everywhere you go.
  • Mobile Protect blocks scams: Your roaming traffic routes back through Singtel’s secured network in Singapore, so scam links, phishing sites and malicious servers are automatically detected and blocked in real-time. This keeps you protected locally and overseas.
  • No VPN needed for apps: Some countries may have local restrictions, but with Singtel Roaming you can continue using your usual online services without setting up a VPN. Everything just works the moment you land, so you stay connected to your messages, social platforms, maps, search, and daily digital life like normal.
  • Multi-destination coverage: Singtel has both single destination and multi-country roaming plans, so you can travel across different regions without needing to buy separate data packs each time.
  • No bill shock: Stay protected from unexpected charges with Singtel Roaming.
    • 1. UnlimitedRoam: One fixed price for 14 days of unlimited data
      • Skip the guesswork. Pay a single upfront fee and enjoy unlimited data for 14 days—no hidden costs, no nasty surprises. Use your phone freely wherever you go.
    • 2. ReadyRoam: Auto-renews so you stay connected at the same high-speed rate
      • Prefer a flexible option? ReadyRoam kicks in as soon as you touch down or run low on data. It renews automatically, so you always stay connected at the same affordable high-speed rate. No unexpected pay-per-use charges.
