Introduction The Rise of eSIM Technology

In the last few years, eSIM (embedded SIM) technology has completely transformed how people stay connected across borders. It has simplified the way travelers use mobile networks, eliminating the need to physically purchase and insert SIM cards in each country. Instead of searching for local stores or fumbling with tiny SIM trays, users can now activate a plan within minutes by scanning a QR code a true game-changer for global connectivity.

This digital innovation offers not just ease of use, but also flexibility and speed. For frequent travelers, business professionals, and even digital nomads, eSIMs provide a seamless way to manage multiple networks from one device. However, one common question still arises can you use eSIM for voice calls and SMS? The answer isn’t always straightforward; it depends on your mobile carrier, the specific eSIM plan, and your smartphone’s compatibility.

As international travel becomes increasingly digital, companies like Hubbing eCom are stepping in to make connectivity effortless. Their flexible and affordable eSIM solutions ensure travelers can communicate, navigate, and share experiences without interruption. This guide will help you understand how eSIMs work with voice and SMS, their limitations, and how you can maximize your travel experience with the right plan.

What Exactly Is an eSIM?

An eSIM, or embedded SIM, is a digital replacement for the traditional plastic SIM card. Instead of inserting a removable chip, the eSIM is already built into your device and can be programmed remotely. This means your phone can connect to different mobile networks without requiring a physical SIM swap.

Here’s what makes it unique:

• No physical card: The eSIM is permanently embedded in your device’s hardware, reducing the risk of losing or damaging it.
• Multiple profiles: You can store several mobile operator profiles and switch between them easily, making it ideal for frequent travelers or users managing both work and personal numbers.
• Remote setup: Plans can be activated instantly using a QR code or app no need for store visits or waiting periods.

Most flagship smartphones from Apple, Samsung, and Google already come with eSIM support. For international travelers, this technology offers incredible convenience and adaptability, letting them move between countries while maintaining seamless network access.

Can You Use eSIM for Voice Calls and SMS?

Yes but with some conditions.

Not all eSIM plans come with voice and SMS capabilities. Many are data-only plans, designed primarily for internet browsing, social media, or navigation. Others offer full mobile services data, voice, and SMS just like a traditional SIM card. Whether your eSIM supports calling and texting depends entirely on your carrier and the type of plan you choose.

Many travel eSIM providers focus on data-only connectivity because travelers today rely on internet-based apps such as WhatsApp, Skype, and iMessage for communication. However, if you still depend on standard voice calls or need SMS for receiving OTPs or verification codes, you’ll need a plan that explicitly includes these services.

Typically, local or domestic eSIMs from telecom providers offer complete service (voice, SMS, and data), while international or global travel eSIMs mainly provide data to keep costs low and connectivity fast.

Understanding eSIM Plans Data Only vs. Full Service

Choosing the right eSIM plan depends on how you plan to use your mobile connection. Below is a breakdown of the different types of plans and what they offer:

Type of eSIM Plan	Includes Data?	Includes Voice/SMS?	Best For
Data-only eSIM	Yes	No	Internet browsing, streaming, maps, emails
Voice + SMS eSIM	Yes	Yes	Business travelers, long-term stays
Hybrid/Regional eSIM	Varies	Yes/No Depends on provider	Frequent travelers needing flexible options

Key takeaway:
If you’re a short-term traveler or tourist, a data-only eSIM is usually enough to stay connected online. But if you rely on traditional calls, SMS verifications, or business communication, it’s worth investing in a full-service eSIM that includes both voice and text support.

How to Make Voice Calls with eSIM Data Plans

Even if your eSIM plan doesn’t include voice calling, you can still make calls using Voice over Internet Protocol (VoIP) apps. These platforms rely on your mobile data connection or Wi-Fi, bypassing traditional cellular networks.

Popular VoIP Options

• WhatsApp: Free high-quality voice and video calls with strong global coverage.
• Skype: Excellent for international calling with low rates and business features.
• FaceTime / FaceTime Audio: Perfect for Apple-to-Apple communication.
• Google Voice: Provides a U.S.-based number that supports calls and SMS via the internet.

These methods are extremely cost-effective and convenient, especially for travelers trying to avoid high roaming fees. However, they rely entirely on your data quality poor signal or limited bandwidth can affect call clarity. Additionally, some countries restrict VoIP services, so it’s best to check local regulations before traveling.

With Hubbing eCom’s eSIMs, you can enjoy high-speed data that ensures smooth VoIP performance wherever you are, keeping you connected with loved ones or colleagues without disruptions.

How to Send Text Messages Using eSIM

Traditional SMS functions depend on your mobile carrier’s network, which means data-only eSIMs typically don’t support SMS. Fortunately, several modern alternatives allow you to send and receive messages over data.

1. Internet-Based Messaging Apps

Apps like WhatsApp, Telegram, Signal, and Viber use internet data to send messages instead of relying on mobile networks. These platforms also offer encryption, media sharing, and voice notes, making them ideal replacements for standard SMS.

2. Using iMessage or RCS

Apple’s iMessage and Android’s Rich Communication Services (RCS) let you send texts over Wi-Fi or mobile data, effectively bypassing traditional SMS systems while maintaining a native texting experience.

3. Virtual Numbers

If you require SMS for business, OTPs, or verification codes, consider virtual number apps such as Google Voice, Twilio, or TextNow. These tools assign you a working number that functions online, letting you send and receive messages without a physical SIM card.

This flexibility is why eSIMs have become the preferred choice for modern travelers combining mobility, convenience, and advanced communication solutions.
