Not all eSIMs are created equal. The functionality you get depends entirely on the type of eSIM plan you purchase. Here’s a detailed comparison:

Key takeaway: If you need voice calling and SMS, make sure to choose an eSIM plan that explicitly states support for these features.

Some mobile operators and select eSIM providers offer full-featured eSIMs with calling and SMS enabled. These work just like traditional SIMs — you can dial numbers, receive calls, and use your device’s regular calling features.

These eSIMs are perfect for:

• Staying reachable with a local number
• Making local and international calls
• Business communication while traveling

Most global eSIM providers (such as Airalo, Nomad, or Holafly) offer data-only plans, which do not support traditional voice calls. However, you can still make calls through apps such as:

• WhatsApp
• Telegram
• Skype
• Zoom
• Signal
• Google Voice
• FaceTime Audio

These calls use your data connection (VoIP) instead of your mobile number.

Pro Tip:
If your device supports dual SIM (physical + eSIM), you can keep your original SIM active for calling and pair it with a data-only eSIM for cheaper internet while abroad.

Just like voice calls, sending and receiving SMS messages (the traditional text message format) requires a mobile number that supports SMS functionality.

✅ SMS-Capable eSIMs

To send and receive SMS messages, your eSIM must:

• Include SMS services in the plan
• Assign you a valid mobile number (MSISDN)
• Be from a carrier that supports two-way messaging

These are typically postpaid or full prepaid eSIMs from national carriers or a select few global providers.

You cannot send or receive SMS through a data-only eSIM. However, messaging apps that work over data include:

• iMessage
• WhatsApp
• Facebook Messenger
• Viber
• Instagram
• Telegram

These use internet data to send messages and are not tied to your phone number.

Important: OTP & 2FA

If you need to receive bank codes, one-time passwords (OTP), or verification messages, keep your primary SIM active via dual SIM setup.

Most travel eSIM brands are data-only, but some providers — including traditional mobile operators and niche global carriers — offer full-featured plans. Here’s a comparison:

If you want to use mobile data from an eSIM and still keep your regular number active for calls and SMS, the best approach is to use a dual SIM configuration:

Benefits of Dual SIM with eSIM:

• Keep your home SIM active to receive OTPs, messages, and calls

• Easily manage business and personal numbers

• Compatible with most modern smartphones:

  • iPhone XS and newer

  • Google Pixel 4+

  • Samsung Galaxy S20+

How it works:

• Slot 1: Your physical SIM (with voice/SMS)
• eSIM: Your travel data plan
• Toggle data usage and default line easily in your phone settings

Before purchasing any eSIM, it’s crucial to verify whether it includes calling and texting. Here’s what to look for:

✅ What Indicates Voice/SMS Support:

• A mobile number is assigned (starts with +1, +44, etc.)
• Terms like “Voice + Data Plan” or “Full-service eSIM”
• Carrier mentions “includes local number”
• Inbound and outbound SMS supported
• Availability of call minutes or text quotas

❌ Red Flags:

• “Data-only” mentioned in plan details
• No mention of SMS or voice
• Focus on internet access only
• Extremely cheap price (usually no voice/text)

When in doubt, always check the FAQs or ask customer support.

An eSIM (embedded SIM) is a digital SIM that’s built directly into your phone, tablet, or laptop. Unlike physical SIM cards, eSIMs do not require a slot, and you don’t need to swap cards when traveling or switching networks.

Here’s how eSIM works:

• You download a data plan digitally via a QR code or app.
• Your device connects to a local or global mobile network using remote provisioning.
• You can store multiple eSIM profiles and switch between them based on your location or usage.

Benefits of using an eSIM:

• No need to visit stores or buy physical SIMs abroad.
• Activate or change plans instantly through an app.
• Store multiple profiles (home, travel, business).
• Perfect for travelers, digital nomads, and remote workers.

Yes—but only if the eSIM plan includes multiple countries in its coverage.

Some eSIMs are meant only for single-country use (e.g. France, Japan), while others are designed for international use across dozens of destinations. These are often categorized as Local, Regional, or Global eSIMs.

If your travel involves crossing borders or visiting multiple countries in a short period of time, a multi-country eSIM is the most convenient option.

Common use cases include:

✈️ Frequent Travelers

Stay connected from one airport to the next without relying on roaming or airport Wi-Fi.

Live and work abroad with one eSIM profile that keeps you connected globally.

Choosing the right eSIM for international use can save you both money and frustration. Here are the most important factors to consider:

1. Coverage

Ensure the eSIM covers all the countries on your itinerary. Global eSIMs can cover 100+ countries, while regional plans focus on a specific zone like Europe, Asia, or Latin America.

2. Validity Period

Look for flexible validity periods. Some eSIMs offer 7-day or 30-day passes, while others let you top up or pause your data over a longer period (even up to 1 year).

3. Network Speed & Quality

Make sure the eSIM connects to top-tier local networks (like Vodafone, Orange, or AT&T) in each country for better speed and coverage.

4. Plan Type

Most travel eSIMs are data-only, which works fine for most users (with WhatsApp, Zoom, Google Maps, etc.). Some providers offer plans with calls and SMS, which may be useful for business or banking verifications.

5. Flexibility

Choose eSIMs that allow easy reactivation, switching between profiles, or pausing your plan during low-usage periods.

Several top eSIM providers offer reliable multi-country plans with global and regional options. Here are some of the most recommended:

To get the most out of your eSIM when traveling between countries, follow these simple tips:

3. Consider a Dual SIM Adapter

For specific phone models, physical adapters exist to simulate dual-SIM functionality, but they don’t replace eSIM convenience.

An eSIM, or embedded SIM, is a digital version of the traditional SIM card. It’s built directly into your smartphone, tablet, smartwatch, or laptop, eliminating the need for a physical SIM card tray.

Unlike a traditional SIM, which requires you to physically swap cards to change networks or phone numbers, an eSIM lets you:

• Activate a mobile plan instantly by scanning a QR code or using an app.
• Switch between carriers or plans without needing a new SIM card.
• Manage multiple plans on the same device, often without needing a dual-SIM tray.

eSIMs are especially useful for international travelers, business users, and anyone who values flexibility and convenience in their mobile connectivity.

Yes, most modern smartphones and devices allow you to store and use multiple eSIM profiles. However, you can only activate a certain number of them at the same time, depending on the hardware and software of your phone.

How It Works:

• You can store multiple eSIM profiles on your device (usually between 5 and 10).

• Only one or two profiles can be active at the same time.

• Devices that support Dual SIM Dual Standby (DSDS) can connect to two networks simultaneously, such as:

  • 2 eSIMs active together (common in newer iPhones).

  • 1 eSIM + 1 physical SIM (common in many Android devices).

So, while you can’t use all stored eSIMs at once, you can switch between them easily and activate the ones you need when you need them.

Not all smartphones are created equal when it comes to eSIM support. Some can only use one eSIM at a time, while newer models allow for dual eSIM functionality—letting you use two eSIMs simultaneously without a physical SIM card at all.

Examples of Popular Devices:

Pro Tip: Always check the manufacturer specs and local carrier support before relying on dual eSIM functionality abroad.

There are several practical and strategic reasons why users benefit from storing and activating multiple eSIMs:

• Label your eSIMs clearly for quick access and switching on the go.
• Check your roaming and data settings to ensure you don’t exceed usage limits.

An eSIM (embedded SIM) is a digital version of the traditional SIM card. Unlike the physical SIM card that you insert into your phone, an eSIM is already embedded into your device’s motherboard and can be programmed remotely by downloading different network profiles.

This means you don’t need to visit a store to purchase a SIM card or wait for one to be shipped. Instead, you can scan a QR code or use an app from an eSIM provider and instantly activate a mobile plan—whether you’re in your home country or halfway across the world.

Most newer smartphones, tablets, and smartwatches now support eSIM. Apple, Google, Samsung, and other major manufacturers have embraced this technology across many models.

One of the biggest benefits of eSIM for travelers is how easy it is to get connected. Instead of standing in line at an airport kiosk or hunting for a SIM card shop in a foreign city, you can buy and activate a data plan from your phone—before you even leave your home country.

Many eSIM providers allow you to purchase and download a plan instantly, sometimes within minutes. This is incredibly helpful if you land in a new country late at night or during a holiday when stores are closed.

With eSIM, there’s no need to remove your existing SIM card, which means your primary phone number and contacts stay safe and active. Most smartphones with eSIM support dual SIM functionality, so you can use your home SIM for voice or text (if needed) and your travel eSIM for mobile data.

This is especially beneficial for:

• Business travelers who still need to receive calls on their home number.
• WhatsApp users who want to keep their account linked to their original number.
• Travelers who want to avoid losing or damaging their primary SIM.

International roaming fees can be extremely expensive. eSIMs provide a cost-effective alternative by offering local or global data plans that are prepaid and transparent.

You can choose from:

• Local eSIMs (cheapest, country-specific).
• Regional eSIMs (like Europe, Asia, North America).
• Global eSIMs (covering 80+ countries for frequent flyers).

This allows you to choose a plan that fits your needs and budget, without surprise fees or long-term contracts.

If you’re traveling to multiple countries on a single trip, switching SIM cards for each country is a hassle. Some eSIM providers offer regional or multi-country plans that work across several destinations.

For example:

• A European eSIM plan may work across 30+ EU countries.
• A global eSIM can provide coverage in over 100 countries without switching plans.

This is perfect for backpackers, digital nomads, cruise passengers, or international business travelers.

eSIMs are inherently more secure than traditional SIM cards. There’s no physical chip to lose, damage, or steal. Plus, they reduce the plastic waste associated with disposable SIM cards and packaging.

Because they are remotely managed, many eSIMs also allow you to:

• Pause or resume your plan easily.
• Switch between plans in seconds.
• Keep backups of your profiles in certain apps.

Although eSIM technology is rapidly expanding, not all devices support it yet. Many newer smartphones do, but budget models or older phones may not have eSIM capability.

Make sure to:

• Check your device’s specifications for eSIM support.
• Ensure that your device is unlocked, as some carrier-locked phones don’t allow eSIM activation with other networks.

Most international eSIM plans are data-only, meaning they don’t include traditional voice calls or SMS. This could be a drawback if you rely on regular phone calls or need to receive text messages for banking or 2FA (two-factor authentication).

However, voice communication over apps like WhatsApp, FaceTime, Zoom, Skype, Telegram, or Google Voice works flawlessly over mobile data, making this issue minimal for most travelers.

Many eSIM providers operate 100% online, which can mean limited live support or slower response times if you run into issues. Always:

• Read reviews before choosing a provider.
• Choose companies with reliable customer service or apps with in-app support and troubleshooting.

eSIM is especially useful in the following travel situations:

• Short-Term Tourists: Avoid expensive roaming fees and enjoy instant connectivity with a prepaid plan.

An eSIM (embedded SIM) is a programmable chip embedded directly into your smartphone, tablet, smartwatch, or even laptop. It performs the same functions as a traditional SIM card: it stores your subscriber profile and allows your device to connect to a mobile network. But unlike a physical SIM card, an eSIM is rewritable and remotely activated.

This means you don’t need to go to a mobile store or wait for a SIM card to arrive by mail. Instead, you can scan a QR code, download a mobile profile, and activate your service instantly—no hardware required.

In simple terms, eSIM makes switching mobile carriers and plans as easy as downloading an app.

The process behind eSIM technology might sound complex, but it’s designed to make your life easier. Here’s a step-by-step look at how it works:

1. Activation: When you purchase an eSIM plan from a provider, you receive an activation code, usually in the form of a QR code or via a digital link.

2. Remote Profile Download: You scan the code with your device, which then securely downloads the SIM profile from the carrier’s server. This includes your mobile number, network access settings, and data plan.

3. Instant Network Connection: Once the profile is downloaded and activated, your device automatically connects to the carrier’s mobile network.

4. Seamless Switching: You can store multiple profiles and switch between them without physically changing anything. Perfect for switching between home and travel data plans.

Behind the scenes, eSIMs use GSMA-compliant protocols to ensure secure communication and interoperability with carriers around the world.
