With international travel now open and the traffic light system in effect, you might be planning a much-needed getaway.
But while video calling friends and family may have become second nature, you'll need to be careful when using your phone in some green travel destinations abroad, to avoid racking up a huge fee.
We take a look at how to save on roaming costs in EU and non-EU destinations.
If you're staying in the EU and travelling the current green list destinations Iceland or Gibraltar, things are clear cut.
Despite the UK officially leaving the EU, most providers still have no plans to stop offering 'roam like at home' (which allows you to use your UK allowance abroad). So for the time being at least, you can use the minutes, messages and data included in your monthly bundle at no extra cost.
Most providers do have a fair usage policy if you have a high data package, so make sure you check what that is before travelling. Also bear in mind that you could end up paying out of bundle charges if you use it all up.
Roaming outside the EU can be expensive, and with popular locations such as Singapore, Australia and New Zealand currently on the list you'll need to be careful if you're travelling further afield - assuming, of course, you're allowed in.
Three tends to be one of the better networks when it comes to non-EU roaming. Go Roam is available on all packages above 4GB, although other providers such as O2 and Vodafone also offer inclusive roaming with selected high data deals.
Roaming costs can vary a lot between providers and countries so it is vitally important you check the costs wherever you are going.
If you are planning to make a trip this summer, there are some tactics you can employ to cut your data roaming costs.
Some providers have a roaming passport add-on in certain popular destinations, where you can either access a fixed allowance or your UK allowance for a daily fee.
For example, Vodafone charges £6 a day to access your UK allowance of data, minutes and texts in 104 destinations, whereas O2 charges £4.99 for 120 mins and texts as well as unlimited data (although O2 reserves the right to apply traffic management and speed restrictions).
All these add-ons have different clauses and restrictions such as what counts as a daily charging period and how much data you get.
Bear in mind that some add-ons can be automatically triggered by any data used by your device, including background data for updating social media feeds and similar activities. So turn off mobile data until you are ready to use it. Check out the roaming options on your provider's website to see which could be good to enable before you travel.
As per regulations, all providers that charge you for data you've used have to place a data roaming cap to avoid customers getting excessive roaming charges. This cap is set at around £43 (there is a small variation among providers) which, as we've explained above, can be reached very easily if you're not careful.
You can request that your provider removes this cap, but this is risky territory, and could leave you racking up potentially hundreds of pounds with ease.
Ultimately, make sure you check your provider's roaming charges and T&Cs before you travel.
A little data can go a long way if you know how to set up your phone correctly, and do a little preparation in advance. Changing data settings can ensure you don't end up paying roaming fees without realising. Downloading important apps, documents or media in advance, and using wi-fi where available can also be a big help.
Some providers offer better deals than others when it comes to roaming, even to the same destination.
At Which? Switch Mobile, you can find a wide range of deals on low-cost roaming providers, including one-month contract deals that can be ideal as a temporary solution to save money when on your holidays.
