How to Set Up Your Phone for International Travel

June 10, 2025 by Jeremy Lindy

Traveling to another country is exciting, but using your phone abroad can be tricky if you're not prepared. From high roaming charges to no signal at all, the last thing you want is to feel disconnected when you need your phone the most.

 The good news? With a few simple steps, you can set up your phone to stay connected, save money, and avoid stress during your trip. This blog will walk you through exactly what to do before you leave, so your phone is ready the moment you land. Let’s make your travel smarter and more connected from day one.

1. Make Sure Your Phone Is Unlocked and Ready

Before you start using your phone abroad, it’s important to ensure it’s unlocked and fully compatible with your destination’s networks to avoid connectivity issues.

Check Unlock Status

Before you can use a local SIM card or eSIM abroad, your phone must be unlocked. Contact your mobile carrier to confirm. If it’s locked, most carriers will unlock it for free once your contract ends or the device is fully paid off.

Verify Network Compatibility

Different countries use different network bands. Research which frequencies are supported in your destination and check that your phone is compatible. GSM-compatible phones are ideal for international use.

2. Pick the Best SIM or eSIM Option

Choosing the right SIM or eSIM option can make a big difference in your travel experience, helping you stay connected without overspending or facing unnecessary hassles.

Use a Local SIM Card

A local SIM card is usually the most cost-effective choice. These are available at airports, convenience stores, and mobile kiosks. Once installed, you'll get a local number and access to affordable data and call rates.

Activate an eSIM Before You Fly

If your phone supports eSIM, consider activating one before you depart. eSIMs let you install digital plans without switching physical cards. They offer flexibility and convenience, especially for short trips or multi-country travel. The best esim providers plans that suit their destination, data needs, and length of stay, ensuring consistent access to data and communication throughout the trip.

Use an International Roaming Plan

Some carriers offer international roaming packages with daily or monthly rates. They are convenient and easy to activate, but they tend to be more expensive than local or eSIM options.

3. Adjust Key Settings to Prevent Extra Charges

Adjusting these key settings not only helps you avoid surprise charges but also ensures your phone runs efficiently, keeping you connected and in control throughout your trip.

Disable Data Roaming

Turning off data roaming before departure ensures you won't incur unexpected charges. You can enable it again after installing a local SIM or eSIM with a data plan.

Turn Off Background Data

Apps running in the background can eat up your data. Limit background app activity in your phone settings to reduce usage and extend your plan.

Update Apps and Download Offline Content

Update important travel apps before leaving home. Download offline maps, translation packs, music, and videos so you can access them without using mobile data.

4. Secure Your Phone and Personal Data

Protecting your phone and personal data is crucial when traveling internationally. Taking these security steps helps keep your information safe and your device secure wherever you go.

Enable Strong Security Features

Use biometric locks, strong passwords, and PINs to protect your phone. Consider a password manager for added security while accessing online accounts abroad.

Activate Find My Device

Both iPhones and Androids have location tracking and remote wipe features. Ensure these are enabled so you can locate or erase your phone if it's lost or stolen.

Use a VPN for Public Wi-Fi

Public Wi-Fi networks in airports, hotels, and cafés are often unsecured. Use a VPN to encrypt your connection and protect your data when accessing sensitive apps or sites.

5. Track and Control Data Usage

Tracking and controlling your data usage is key to avoiding unexpected charges and staying connected smoothly throughout your international trip. Here’s how to manage it effectively.

Monitor Your Data Regularly

Most smartphones offer tools to track data use. Set alerts or limits to avoid using more than your plan allows, especially when you’re not on Wi-Fi.

Use Offline Features

Many apps support offline modes. Google Maps, translation apps, and streaming platforms all offer downloadable content, perfect for staying connected without burning through data.

Connect to Wi-Fi Smartly

Use free Wi-Fi in hotels, cafés, and public spaces, but always ensure the network is secure. Disable auto-connect to unknown networks to avoid accidental use.

6. Prepare for Communication on the Go

Preparing your phone for communication abroad ensures you stay connected effortlessly. Let’s explore key tips to make calling and messaging simple while traveling internationally.

Learn International Dialing Codes

International dialing requires using the correct country codes. Save important numbers in international format (for example, +1 for USA, +61 for Australia) so they work no matter where you are.

Use Wi-Fi-Based Messaging

Messaging apps like WhatsApp, Telegram, and Viber use Wi-Fi or mobile data instead of SMS. These are ideal for staying in touch without extra fees, especially when you're using hotel Wi-Fi.

7. Pack the Right Phone Accessories

Having the right accessories can make all the difference in keeping your phone charged, safe, and ready to use throughout your international journey.

Bring a Universal Adapter

Power outlets differ across countries. A universal travel adapter ensures you can plug in and charge anywhere. Choose one with USB ports for added convenience.

Carry a Power Bank

Flights, bus rides, and sightseeing can drain your battery. A high-capacity power bank lets you charge on the go and keeps you connected all day.

Protect Your Device

Use a rugged phone case and screen protector. If you're visiting beaches, lakes, or rainforests, a waterproof pouch is a smart addition to your gear.

8. Install Essential Travel Apps

To make your trip smoother and more enjoyable, installing the right travel apps can help you navigate, communicate, and manage your budget with ease while abroad.

Navigation Tools

Install apps like Google Maps or your destination’s local transit app. Download maps in advance to navigate offline, which saves data and ensures accuracy in spotty coverage areas.

Language Helpers

Google Translate and similar apps allow you to translate menus, signs, and conversations. Download offline language packs before you go.

Currency and Budget Trackers

Install apps for real-time currency conversion and expense tracking. They help you stay within budget and avoid conversion confusion.

Conclusion

Getting your phone ready for international travel does not have to be complicated. With a little planning, such as unlocking your device, choosing the right SIM or eSIM, updating settings, and packing smart, you can avoid surprises and stay connected from day one.

Think of your phone as your travel assistant: navigation, communication, budgeting, and safety all in one place. So before you zip up your suitcase, double-check these tips and give yourself peace of mind. A few minutes now can save you hours of hassle later. Safe travels and happy connecting!

FAQs

1. What should I do before I go travelling abroad if I want a mobile phone?

To avoid costly bill shock, I suggest that you switch off data roaming for your overseas travel, turn on Airplane mode, and only turn Wi-Fi back on in a Wi-Fi hotspot.  You can also use a local SIM or eSIM while you are travelling for lower rates for calls and data. 

2. What do I have to do to set my mobile phone for international travel?

First, confirm your features, unlock your phone for a local SIM or eSIM plan purchase, disable data roaming, update applications, and download your offline content ahead of time so that you do not incur any data charges while you are traveling overseas.

3. What needs to be done to set my phone for international travel? 

Make sure you unlock your phone, check for network compatibility, back-up data, and download the travel apps too. Remember to switch off data roaming, download and review local offline maps, and ensure you take your travel accessories with you too- chargers and plug/adapters.
