Savvy travellers can use Yesim as a smart connectivity option for their holidays abroadAn eSIM offers a great solution to manage your travel connectivity (Image: Yesim)Brits traditionally plan a holiday down to the last penny: flights, hotel and transfers are paid for weeks before departure. But the moment you land in Tokyo, Bangkok or Istanbul, mobile connectivity and roaming costs become far harder to keep under control. Making sense of mobile tariffs can be difficult, so the cost of staying connected abroad isn't always obvious before you travel. Using your smartphone less isn't always practical, especially when you rely on it for maps, banking apps, messaging, and booking transport. So to help manage connectivity costs, many travellers are choosing a travel eSIM. It lets users plan mobile data usage before they travel, with costs and data allowances shown in advance. One provider offering travel eSIM services is the Swiss company Yesim, which has been developing international eSIM services since 2019.
eSIMs can usually be set up before travelling and are supported by most modern smartphones

How roaming can affect holiday spending These days, our smartphones are central to travelling, from boarding passes and navigation to mobile payments. As a result, many people connect to a local network as soon as they land without giving much thought to how roaming charges work. Depending on your mobile plan and destination, this can lead to unexpected costs. Background app updates, cloud syncing and other automatic processes may also use data while abroad. Daily roaming passes Daily roaming passes are designed to make charges more predictable, but costs can still add up depending on where you travel and how long you stay. Understanding how charges apply before travelling can help avoid unexpected bills, which is one reason some travellers are considering alternatives such as travel eSIMs. Travel eSIM: plan before you fly How an eSIM works An eSIM is a chip built into many modern smartphones and other devices that allows mobile network profiles to be downloaded remotely. Travel eSIM providers build on this technology by offering apps where users can choose a destination, purchase a data package and install it before travelling. Once they arrive, compatible devices can connect using the new profile without needing to buy a physical SIM card. Predictable pricing One benefit of a travel eSIM is that the cost of a data package is known before you travel. Convenience Travel eSIMs also allow travellers to arrange mobile data before departure. If additional data is needed during the trip, users can usually purchase another package through the app. Many smartphones support using both a primary SIM and an eSIM simultaneously, allowing users to keep their UK number for calls and texts while using a separate data plan abroad.
