- At the outset, it’s important to note that making an emergency call does not require a SIM card or a roaming agreement between your home network and the networks of the visited country. As long as your mobile device is compatible with the mobile networks in the visited country your phone has been designed such that even if you have no other services or your services have been disconnected by your service provider you’ll still be able to make emergency calls.
- As mobile networks across the globe are shutting down their 2G/3G networks in order to provide a new generation of technology and services, all you need to do is ensure that when you travel, your mobile device is 4G and VoLTE (Voice over a 4G network) compliant. Most mobile handsets manufactured after 2015 are, but it’s always best to check with your provider.
- Although at the time of writing this guidance most networks continue to have their 4G and 5G networks complimented with either a 2G or a 3G network but these are being decommissioned fast across the globe, so it’s always best to ensure your device is already VoLTE ready.
- So that’s sorted, however when it comes to making other voice calls (not emergency calls), there are certain other factors that need to be taken into account.
