Can an eSIM Make Calls While Traveling Abroad?

When traveling internationally, an eSIM can be an excellent way to save money on international roaming fees and portable Wi-Fi hotspot data charges.

However, eSIM may not be the ideal option if privacy is at the forefront of your mind as thieves cannot physically remove the SIM and hijack your phone number like they can with physical cards.

How to make a call with an eSIM

eSIMs provide an effective means of staying connected while traveling abroad, using data connections instead of cell phones in order to make calls over the internet instead of paying expensive roaming charges. Please keep in mind, however, that calling over the internet consumes significant data usage so please plan accordingly when making phone calls via this method.

To activate an eSIM on your phone, head into its settings and navigate to SIMs. Here you’ll see your current cell number as well as an option to add an eSIM card – tap this option and enter your carrier code!

Once activated, your device will use its eSIM automatically when traveling abroad to avoid international roaming fees while remaining in touch with friends and family. Apps like WhatsApp or Skype allow for calls over the internet which are much cheaper than traditional telephone calls.

Wi-Fi calling

Wi-Fi calling is a feature available on many eSIM compatible smartphones that enables you to make calls over the Internet rather than via your carrier’s network connection, similar to how VoIP apps like Skype, WhatsApp and Messenger operate – only this time it’s built directly into the phone dialer itself.

Using a portable Wi-Fi hotspot

Mobile Wi-Fi hotspots make it possible to connect multiple devices simultaneously to Internet access. By creating a WiFi network through your cellular data plan, they create an instant network which is ideal for remote areas with weak cell signals or in areas without an available signal. Some smartphones even come equipped with built-in hotspots; alternatively portable Wi-Fi hotspots are widely available from electronics retailers and online vendors.

Most hotspots connect to cellular networks, so a compatible SIM card will be required for them. With various plans such as pay-as-you-go and unlimited options available, these devices are also great for travelers to save on international phone and data charges.

Note that electronic SIMs (eSIMs) may not be as secure or private as traditional SIM cards and that there can be privacy concerns associated with them. Some eSIM providers have even been accused of tracking users through websites and apps which could compromise your privacy and lead to unwanted marketing offers.

Using a local SIM card

If you wish to use your own mobile phone in another country, there are a variety of solutions. One is purchasing a local SIM card for data and voice calling; this option may be best for travelers needing to stay in contact with loved ones back home. Alternatively, portable WiFi hotspots (also referred to as pocket WI-Fi, MiFIs or mobile Wi-Fi hotspots) provide wireless router connectivity through tiny gadgets you simply plug your SIM card into. They are inexpensive devices which can either be purchased or rented.

While eSIMs may be convenient, they’re far from ideal. Switching carriers when traveling frequently is more cumbersome and apps may track your usage to deliver targeted ads or improve product offerings. However, some companies are working on tools to make the process simpler – for instance WorldSIM provides iOS app that lets users add roaming eSIM while keeping access to their number and iMessages.
