Your Complete Guide to Smart Mobile Phone Use When Travelling

Whether you're hopping on the Eurostar to Paris for the weekend, catching a long-haul flight to Thailand, or road-tripping through the Scottish Highlands, your mobile phone is probably the single most important item in your bag. It's your map, your translator, your boarding pass, your camera, and your lifeline - all in one pocket-sized device.

But travelling with your phone isn't as simple as just throwing it in your bag and hoping for the best. A few smart decisions before you leave - and a couple of cheap bits of kit - can mean the difference between breezing through your trip and spending your first afternoon abroad desperately searching for a Wi-Fi signal with a dead battery.

Here's everything you need to know.

1. Charge Up (and Bring Backup Power)

Let's start with the most obvious tip that most people ignore until it's too late: bring a portable battery pack.

Your phone's battery doesn't last forever, and when you're travelling, it works harder than usual. You're using GPS constantly, taking photos, streaming music, sending messages, and - let's be honest - doom-scrolling during the airport delay. All of that drains your battery significantly faster than a typical day at home.

A good portable power bank (also called a power bank or battery pack) can charge your phone once or twice from flat, and they're genuinely small enough to slip into a jacket pocket. Here's what to look for:

  • Capacity: A 10,000mAh bank will give most smartphones roughly two full charges. A 20,000mAh bank is better for longer trips or if you're also charging earbuds, a tablet, or a smartwatch.
  • Output ports: Look for USB-C charging so you can top up the bank itself quickly - and check it also has the right port for your phone.
  • Weight: Bigger isn't always better when you're carrying everything on your back. A 10,000mAh bank typically weighs around 200g. Perfectly manageable.
  • Airline rules: Most airlines allow power banks in hand luggage only (not checked bags). The standard limit is 100Wh, which covers most consumer models - but always check with your airline before you fly.

Brands like Anker, Belkin, and Mophie make reliable options for around £20-£40. It's one of the cheapest travel investments you'll ever make.

2. Download Your Maps Before You Go

This one is a game-changer. Even if you have data abroad, mobile signal can be patchy - especially in rural areas, mountain regions, tunnels, or on the underground. And if you're relying on live navigation when signal drops, you'll suddenly find yourself stranded at a roundabout with no idea which exit to take.

The solution is simple: download offline maps before you leave home.

Both Google Maps and Apple Maps support offline downloads, and it takes less than five minutes. Here's exactly how to do it.

How to Download Offline Maps on an iPhone (Apple Maps)

Apple Maps added offline map downloads with iOS 17. Here's how to get yours:

  1. Open Apple Maps on your iPhone.
  2. Tap your profile picture (or initials) in the top right corner.
  3. Select Offline Maps.
  4. Tap Download New Map.
  5. Search for the city, region, or country you're visiting.
  6. Use the pinch/zoom gesture to adjust the area you want to download.
  7. Tap Download.

The map will save to your device and work even when you have no internet connection. You can navigate, search for places, and get directions - all offline.

A few things to note for iPhone users:

  • You'll need iOS 17 or later. If you're not sure which version you're on, go to Settings > General > About.
  • Offline maps expire after 30 days, so download them close to your travel date (or update them if you're going away for longer).
  • Make sure you have enough storage space. A map of a major city takes around 200-500MB; a whole country can be 1-2GB or more.

How to Download Offline Maps on Android (Google Maps)

Google Maps has had offline map support for years, and it works brilliantly.

  1. Open Google Maps on your Android phone.
  2. Search for the city, region, or country you want to download - or simply navigate to that area on the map.
  3. Tap the name or address that appears at the bottom of the screen to open the location card.
  4. Tap the three-dot menu in the top right of the card.
  5. Select Download offline map.
  6. Adjust the area using pinch/zoom to include all the places you need.
  7. Tap Download.

Once downloaded, your map will be available under Menu > Offline maps so you can manage, update, or delete it.

A few things to note for Android users:

  • Google Maps offline works for navigation and basic search, but some features (like live traffic or Street View) require an internet connection.
  • Offline maps expire after 15 days by default, but you can set them to auto-update when you're on Wi-Fi.
  • You can download multiple maps - for example, if you're visiting several countries, download each one separately.

Other Mapping Options Worth Knowing

If you want something more robust for hiking, cycling, or areas with poor map data:

  • Maps.me - A completely free, community-built map app that works entirely offline. Excellent for rural areas and countries where Google Maps data is sparse.
  • OsmAnd - Based on OpenStreetMap, packed with features, great for outdoorsy travellers.
  • HERE WeGo - Another solid offline option, particularly good for driving.

All of them are free to download and use.

3. Keep Your Phone Safe and Accessible

It sounds obvious, but losing your phone abroad isn't just an inconvenience - it can make your whole trip grind to a halt. A few simple precautions go a long way:

  • Use a travel case or belt pouch in busy tourist areas. Pickpockets target phones in back pockets and bags with open tops.
  • Enable Find My (iPhone) or Find My Device (Android) before you travel. If your phone is lost or stolen, you'll be able to locate it, lock it remotely, or wipe it - all from another device.
  • Back up your photos regularly to cloud storage so you don't lose them if your handset goes missing.
  • Take a photo of your IMEI number (dial *#06# to find it) before you travel. If your phone is stolen, you'll need this number to report it to the police and your network.

4. Manage Your Screen Time and Battery Settings

Being abroad doesn't mean being glued to your phone, but when you do use it, you want to make sure the battery lasts. Here are a few settings worth adjusting before you leave:

  • Turn off background app refresh for apps you're not actively using. Both iOS and Android allow this under battery/app settings.
  • Reduce screen brightness - it's one of the biggest battery drains.
  • Turn on Airplane Mode when you don't need connectivity (on a flight, obviously, but also in areas with no signal, since your phone burns battery searching for a network).
  • Disable location services for apps that don't need them. Only your maps app and camera really need GPS most of the time.
  • Use Low Power Mode / Battery Saver when you're below 30% and not near a charger.

5. 1pMobile Customers: You Don't Need a Travel SIM in Europe

Here's the really good news if you're a 1pMobile customer: if you're travelling anywhere in the EU, you don't need to do a thing.

Your 1pMobile SIM works exactly as it does at home across all 46 EU roaming destinations - including popular holiday spots like Spain, France, Greece, Italy, Portugal, Croatia, the Netherlands, and more. Your calls cost the same, your texts cost the same, and your data works from your existing UK allowance.

No travel SIM. No swapping out your SIM card at the airport. No temporary number that your contacts don't recognise. No unexpected bills when you get home.

Just pop your SIM in (or use your eSIM), and go.

The destinations covered include:

Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, and more - 46 destinations in total.

One thing to note: if you're travelling for an extended period and plan to use data heavily - for work, for example - there is a fair-use surcharge of £1 per day if your roaming exceeds 45 days within a 90-day period. This is a standard EU requirement that applies to all UK providers. For a typical holiday, you'll never come close to hitting it.

6. Travelling Outside Europe? Here's How to Keep Data Costs Down

If you're heading further afield - to the USA, Canada, Australia, Thailand, India, or anywhere outside the EU roaming zone - it's worth planning ahead to avoid expensive roaming charges.

Here are your three best options:

Option 1: Buy a Local Data SIM on Arrival

In most countries, you can pick up a pay-as-you-go data SIM at the airport or a local phone shop for a few pounds equivalent. In places like Thailand, India, and the USA, local SIM cards are remarkably cheap - often £5-£15 for a week or two of unlimited data.

The only downside is that you'll temporarily have a different phone number. If that's fine for your trip, it's often the cheapest option. Make sure your phone is unlocked before you travel - 1pMobile handsets are sold unlocked, but if you have a phone from another network, check before you go.

Option 2: Get a Data-Only Travel eSIM

This is increasingly the smart traveller's solution. Travel eSIM providers like Airalo, Holafly, and Ubigi sell data-only eSIMs that you can buy and install on your phone before you even leave home. They work in parallel with your UK SIM - so you keep your UK number for calls and texts, and use the travel eSIM for data.

Benefits:

  • No swapping physical SIMs
  • Install it in minutes from your phone
  • Available for most popular travel destinations
  • Prices are often far lower than standard roaming rates
  • Some offer unlimited data plans for specific countries

If your phone supports eSIM (most modern smartphones do, including all recent iPhones and many Android flagships), this is well worth considering for long-haul trips.

Option 3: Use Wi-Fi Wherever You Can - For Free

It's not always the most convenient option, but free Wi-Fi is more widely available than ever. Hotels, cafés, restaurants, shopping centres, airports, and public transport hubs in most countries offer free guest Wi-Fi.

A few tips for staying safe on public networks:

  • Avoid logging into banking apps or sensitive accounts on public Wi-Fi. Wait until you're back on your mobile data.
  • Consider a basic VPN app (many are free for occasional use) if you're regularly using public networks - it encrypts your traffic and protects your data.
  • Download what you need (podcasts, playlists, articles, documents) while you're on hotel Wi-Fi so you can access them on the go without burning data.

7. A Few More Travel-Savvy Tips

Before we wrap up, here are a handful of extras worth adding to your pre-travel checklist:

  • Enable two-factor authentication on your key accounts before you go, so you can still access them abroad if you're using a temporary number.
  • Screenshot your hotel address and confirmation - saves fumbling for Wi-Fi when you're tired and just want to tell a taxi driver where to go.
  • Set up Google Translate's offline language packs (available under Settings > Languages in the app). Translate text, signs, and menus without needing data.
  • Keep your phone charged to at least 50% when you go through airport security - some airports ask you to power it on to prove it works.
  • Notify your bank before international travel if you're making card payments - though with 1pMobile's 1p/MB data rates in the EU, you'll be browsing fine without worrying about data costs.

Quick Pre-Travel Mobile Checklist

Before you leave, run through this:

  • Phone fully charged - and power bank topped up
  • Offline maps downloaded for your destination
  • Google Translate offline languages installed
  • Find My / Find My Device enabled
  • Photos backed up to cloud
  • IMEI number noted or photographed
  • For EU travel: nothing to do - your 1pMobile SIM works as normal
  • For non-EU travel: research local SIM or travel eSIM options
  • Low Power Mode settings reviewed
  • Background app refresh disabled for non-essential apps

Summary

Your phone can be your best travel companion - or a source of stress, dead batteries, and unexpected bills. The difference really does come down to a bit of preparation.

Download your maps before you go. Bring a power bank. Check your roaming situation before you board.

And if you're travelling in Europe as a 1pMobile customer? Breathe easy. You're already covered. Same rates, same network, same simplicity - wherever in the EU your travels take you.

Happy travels from everyone at 1pMobile.

1pMobile offers the UK's lowest PAYG rates - just 1p per minute, 1p per text, and 1p per MB - on EE's 4G/5G network, with EU roaming included across 46 destinations. No contracts, no hidden charges, no nonsense. Find out more at 1pmobile.com.
