Can You Use eSIM for International Voice Calls?

In today’s interconnected world, international travel has become a common occurrence. Whether for business or leisure, staying connected to friends, family, or colleagues abroad is essential. Traditionally, travelers have relied on physical SIM cards or international roaming services for voice calls. However, with the advent of eSIM technology, the way we connect is changing.

But can you use eSIM for international voice calls? The simple answer is: Yes, you can. However, the full picture is more nuanced, as there are several factors to consider when it comes to international calling with an eSIM.

This comprehensive guide will explore everything you need to know about using eSIM for international voice calls, including the benefits, limitations, and how to set up your device for the best experience.

What is an eSIM?

Before diving into how eSIM works for international voice calls, let’s first understand what an eSIM is.

An eSIM (Embedded SIM) is a digital SIM that allows you to activate a cellular plan without using a physical SIM card. It’s embedded into your device and can be programmed remotely by a carrier, which makes it different from traditional SIM cards. Most modern smartphones, smartwatches, and tablets now support eSIM technology.

The key advantage of eSIM is its convenience. You can switch between mobile operators and even use multiple plans simultaneously without having to swap physical SIM cards. This makes it an attractive option for frequent travelers and those looking for flexibility in choosing carriers.

Can You Use eSIM for International Voice Calls?

Now that we know what eSIM is, the question remains: Can you use eSIM for international voice calls? The answer is yes, but with some caveats.

In general, eSIM technology functions the same as a traditional SIM card when it comes to making voice calls. The eSIM is designed to work with the cellular network just like a physical SIM, so you can use it for making local and international voice calls. However, the success and cost-effectiveness of using eSIM for international calls will depend on several factors:

1. Carrier Support for International Calling

Not all carriers support international voice calls on eSIM. While most carriers now offer eSIM for data and local calls, international calling may not be supported by every eSIM provider. Before using your eSIM for international calls, it’s essential to check with your carrier to ensure that international calling is included in your plan or if it requires an additional service or feature.

Some eSIM providers, such as Airalo, Truphone, and GigSky, offer international data plans that can be used in multiple countries, but voice calls may not always be included, or they may come at an extra cost.

2. International Roaming Charges

One of the primary considerations when using eSIM for international voice calls is roaming charges. International roaming can be expensive, and this applies whether you are using a physical SIM card or an eSIM.

When you use an eSIM, your international roaming charges depend on the carrier’s policies. For example, if you're using an eSIM plan that includes international data, voice calls might still incur additional fees, especially if you are using a different country’s network. Some carriers may provide special international plans, while others may charge high fees for international calls.

To avoid unexpected high costs, consider the following options:

• International calling plans: Many carriers offer discounted international calling plans that you can activate for a specific period. These plans can significantly lower the cost of international calls.
• eSIM data-only plans with VoIP: Some eSIM plans only offer data, but you can use this data for VoIP (Voice over Internet Protocol) services like Skype, WhatsApp, or Google Voice. These services offer a way to make voice calls over the internet, bypassing traditional cellular networks and avoiding high international calling charges.

3. Using VoIP for International Calls with eSIM

As mentioned above, using data-based VoIP services is a viable option for international voice calls while traveling with eSIM. VoIP services enable users to make calls over the internet rather than using the traditional cellular network, which often comes with expensive international calling rates.

Some of the most popular VoIP apps that you can use with your eSIM plan include:

• WhatsApp
• Skype
• Google Voice
• Zoom
• Viber

These apps allow you to make calls between countries at lower or no additional cost, provided you have an internet connection (either Wi-Fi or mobile data). If you're using an eSIM plan that includes international data or if you have access to Wi-Fi, this can be an excellent option for making international calls while avoiding roaming charges.

Benefits of Using eSIM for International Voice Calls

Using eSIM technology for international voice calls comes with several notable benefits, especially for frequent travelers:

1. Seamless Network Switching

One of the biggest advantages of eSIM is that it allows you to switch between different mobile carriers without the need to physically change SIM cards. This is especially useful when you’re traveling internationally. Rather than worrying about finding a local SIM card or trying to get a new physical SIM for every destination, you can easily switch to a local carrier or a global eSIM provider with coverage in multiple countries.

This flexibility can also help you avoid expensive international roaming fees, as you can select an eSIM plan that offers competitive international rates.

2. Dual SIM Capability

Another great feature of eSIM-enabled devices is dual SIM support, which allows you to use two different plans simultaneously. For example, you could have one eSIM plan for local calls in your home country and another eSIM plan for international roaming or data when traveling abroad. This is a major advantage over traditional physical SIM cards, which typically only support one SIM at a time.

Dual SIM capability is especially beneficial for business travelers, who may want to keep their work and personal phone numbers separate while traveling internationally.

3. No Need for Physical SIM Cards

Using an eSIM eliminates the need for physical SIM cards, which is convenient and can save you time. Instead of having to hunt for a SIM card store when you land in a new country, you can instantly activate a new plan directly from your phone. For travelers who visit multiple countries, this makes it easier to stay connected without constantly swapping SIM cards.

4. Global Coverage with Global eSIM Providers

Many eSIM providers, like Airalo, Truphone, and GigSky, offer global eSIM plans that provide coverage in numerous countries. This is ideal for frequent travelers who don’t want to deal with the hassle of buying new SIM cards for each destination. Some of these global plans even include international voice calls as part of the package, allowing you to make voice calls without worrying about expensive roaming fees.

Limitations of Using eSIM for International Voice Calls

While eSIM technology offers many advantages, there are also a few limitations when it comes to international voice calls:

1. Limited Carrier Support

Despite the growing adoption of eSIM technology, not all carriers support eSIM, particularly for international calling. In some cases, you may need to opt for an additional international calling plan or a third-party service to make international calls.

2. High Roaming Charges

If you rely on traditional roaming services with your eSIM, you may still encounter high international calling rates. While some eSIM providers offer affordable international data plans, you may have to pay extra for voice calls or texts.

3. Dependence on Internet Access for VoIP

While VoIP services provide an affordable alternative to international voice calls, they require a stable internet connection. If you're traveling in areas with poor connectivity or no Wi-Fi, you may have trouble making calls using apps like WhatsApp or Skype.

4. Compatibility Issues with Some Devices

Although most modern smartphones support eSIM, not all devices are compatible with this technology. Be sure to check your phone’s specifications to ensure it supports eSIM before planning to use it for international voice calls.

How to Set Up eSIM for International Voice Calls

Setting up eSIM for international voice calls is simple, but the process may vary slightly depending on your device and carrier. Here’s a general guide on how to set it up:

1. Check eSIM Compatibility: Ensure your phone supports eSIM technology. Most newer iPhones, Samsung Galaxy phones, and Google Pixels support eSIM.

2. Contact Your Carrier: Make sure your carrier offers eSIM and supports international voice calls or has an international roaming plan.

3. Activate eSIM: Follow your carrier’s instructions to activate eSIM on your phone. This typically involves scanning a QR code or entering a code provided by your carrier.

4. Select Your International Plan: If your carrier offers international voice calling, choose the plan that suits your needs. Alternatively, you can opt for an international data plan and use VoIP apps for calls.

5. Test the Setup: After activating your eSIM, test it by making a local call or an international call to ensure everything works as expected.

Conclusion

Yes, you can use eSIM for international voice calls, but it’s important to understand the nuances involved. The key factors include carrier support for international calling, potential roaming charges, and the availability of VoIP services for more affordable calls. By selecting the right eSIM plan and utilizing VoIP apps, you can enjoy seamless international communication without the hassle of physical SIM cards or exorbitant roaming fees.

As eSIM technology continues to grow, it will likely become an even more attractive option for international travelers looking to stay connected while saving on costs.
