Do you keep yourself connected while travelling overseas?

Ensuring seamless connectivity during international travel is a crucial consideration, especially on business trips. While obtaining a roaming package from your service provider is a common solution, you might face exorbitant bills upon returning home.

The question arises: How can one stay connected without the risk of huge bills?

There are few options:

If you travel overseas a lot, it may be worth considering owning a dual-SIM phone. This is highly recommended due to its cost-effectiveness, easy management, and enhanced security.

Take the popular iPhone as an example, which offers an eSIM and a physical SIM slot. You can convert your primary mobile number to an eSIM and keep the physical SIM slot for your travel SIMs.

  • ✅ Travel SIMs are usually data-only, cheap, and easy to acquire
  • ✅ Travel SIMs can be pre-purchased weeks before you go – it is only activated once you connect it to the network
  • ✅ Your mobile number is still active when overseas (with your eSIM) and the data usage stays with the travel SIMs

Note: Sometimes it is better to use a eSIM travel app e.g. You can buy data and use it in 165 countries without changing SIM cards.

2. Portable 4G Router

Invest in a device, insert the local travel SIM, and share the Wi-Fi with multiple users and devices.

  • ✅ This option proves cost-effective, preserves your phone's battery life and is perfect for single-SIM phones
  • ❌ You will need to carry an extra device
  • ❌ You may miss out on free Wi-Fi – the router is connected by Wi-Fi so you cannot connect to others, for example, hotels

3. Roaming package

Rely on your current roaming service, for example, Telstra charges $10 per day for 1 GB of data and $10 per extra GB. Some other carriers may offer more competitive packages.

  • ✅ This method is straightforward, with no additional purchases, and a pay-as-you-go structure
  • ❌ This can be expensive and occasionally poor internet connectivity


Each option has its pros and cons, allowing you to tailor your connectivity strategy based on your preferences and specific travel needs.

Travel SIMs usually offers better user experience if you spend more data.

  • ✅ Travel SIMs are usually much cheaper than roaming packages
  • ✅ They are prepaid and disposable
  • ✅ It can be a perfect combination with your roaming service to have enough cheap data to use and make calls from your roaming service. Of course, you will have your regular mobile connected as well, so you won’t miss the important calls and text messages
  • ❌ Often limited to data only and will expire after a certain period

❌ Bad example - Exorbitant Telstra bills upon returning home due to roaming data usage of 120 GB

✅ Good example - Paying $129 AUD for 200 GB of data on a travel SIM to Europe

Tip: Travelling to China can be different due to the Great Firewall, which prevents you from accessing Google, Facebook, Teams etc.

It may require a VPN to access these services from a local network. But the travel SIMs purchased outside of China or roaming mobile data packages have no restrictions because your IP is where the SIMs are registered.
