Before you head off, we'll explain how you can save on data overseas. There are also some bits worth downloading before your trip, including TV shows from catch-up apps and offline maps so you can explore new areas without a phone signal. It's also worth setting up location tracking on your devices in case you misplace them.
Keep scrolling for a round-up of tech travel tips submitted by our experts.
Tech tips you can trust –1. Don't forget about roaming costs
If you're planning a trip abroad, keep mobile fees in mind. After all, you don't want to be hit with a mammoth phone bill when you get home.
Many providers have now introduced roaming costs, although some will still let you roam in the EU for free. Your provider should send you a text message when you leave the country, reminding you of the potential charges. If you want to be proactive, check your provider's website in advance.
As a general rule, it's best to stick to wi-fi while you're abroad – that way, powering through your inbox or streaming films won't count towards your data allowance. You can also make WhatsApp calls through wi-fi.
If you need to use your mobile data (it might be inevitable if you're on the move), keep track of how much you're using. Some apps are more data-hungry than others, so it can be painfully easy to hit your limit without realising.

Alternatively, you can link a HDMI cable between your laptop and the TV.

4. Don't forget to download maps in advance
If you rely on your smartphone to help you navigate new areas, we suggest you prepare some offline maps before your trip. That way, you'll be able to use Google Maps even if you're in an area without a phone signal.
There are plenty of free map apps that have offline features, including Maps.me and Google Maps. For our walkthrough, we'll go with Google Maps.
To download offline maps on the Google Maps app, follow these steps:

It can be tempting to take some snaps on your phone by the pool or on the beach, but remember that 'water resistant' and 'waterproof' are two different things.
In other words, 'water resistant' phones aren't invincible. You're better off playing it safe, either by limiting your phone's contact with water or investing in a waterproof pouch. They're available on online marketplaces such as Amazon for less than £20, but note that we haven't tested these in our lab.

Your powerbank doesn't need a tan, so keep it out of the sun and don't abandon it on a car dashboard during a sweltering afternoon.
When a powerbank is exposed to heat for too long, it'll induce chemical reactions in the battery and cause the charger to deteriorate.
If you don't own a powerbank just yet, it could be worth picking one up before your next trip. When shopping for the right model, note the claimed capacity:
Small powerbanks (up to 7,500mAh)Medium powerbanks (7,500-14,999mAh) Large powerbanks (more than 15,000mAh)We've been hands-on with a selection of powerbanks to see which ones are worth chucking in your suitcase – explore our guide to the .7. Don't just store your travel documents digitally
Storing travel documents on your phone or tablet is undeniably convenient, but if you don't have physical copies, you're in trouble if your device stops working or if you lose it.
Our product experts recommended creating physical backups just in case. Put together a folder containing must-haves such as hotel details, directions to important locations and flight documents if needed.
8. Don't let sand destroy your camera
Be extra careful when you're taking your camera to a beach. Our product experts suggest changing lenses underneath the cover of a blanket to prevent any accidents. You might also want to invest in a UV filter to protect the lens from scratches.

For peace of mind, we recommend setting up location tracking on your mobile before you head off. If your device goes for a walk without your permission, you'll be able to track it down (or wipe your files) remotely.
The app you need varies depending on the manufacturer. Here are the three main 'find my' services:
Find My iPhoneSettings Name Find MyFind My iPhone SmartThings Find (Samsung) app trayLife FindFind My Device (Android)Settings Security & PrivacyFind My Device
If your phone is stolen, report the theft to the police and tell your network provider so it can cancel your phone Sim. You'll also need to consider your mobile banking accounts (get in touch with your bank, just to be on the safe side) and change critical passwords.
