Travelling to new countries can be an exciting adventure, but staying connected is always a challenge. Roaming charges can become costly, and Wi-Fi networks could be unreliable. Some areas may not have Wi-Fi networks at all.
eSIM technology has become a popular way for travellers to stay connected while on the go, and removes the hassle of switching SIM cards. Let’s find out what they are, how they work and how to choose the right one for your next international trip.
What Are eSIMs?
An eSIM, the ‘e’ stands for embedded’, is a digital SIM card. It is integrated into devices such as a smartphone or tablet. They are built into a device’s hardware and can connect to a mobile network when programmed remotely.
Unlike physical SIM cards that have been traditionally used, eSIMs are managed digitally. They don’t need to be physically swapped out when changing network carriers as physical ones do.
How Are eSIMs Different To Physical SIMs?
Both SIMs are used to connect devices to a mobile network, but they differ greatly when it comes to their technology and usage.
Physical Vs Digital
Traditional SIM cards are removable chips that are slotted into a device. They usually come in different sizes, standard, micro or nano depending on the device requirements. An eSIM is a digital SIM that is embedded directly into the hardware of a device, and isn’t a physical card.
Activating The Card
In order to set up a physical SIM, a card needs to be bought from a store. The card is then inserted into the device and prompts can be followed to activate it. If you want to change the phone number or carrier, a new card is usually required in most cases.
eSIMs are activated remotely, without needing a card. Most carriers have an app that can be downloaded with a QR code to be scanned. It’s more convenient when changing carriers or plans, as this can be done digitally on the device’s settings.
Dual SIM Functionality
Dual SIM functionality means that a device can support two cards at the same time. However not all devices have two slots for physical SIMS, so this can be tricky when using traditional SIM cards.
Modern smartphones support dual SIM where one physical SIM is used and the other is the digital eSIM. This comes in handy for those who want to keep their original number active while using a local data plan when overseas.
Security Features
It’s easy for physical SIM cards to be removed, taken or lost. This can become a security risk if your SIM card is stolen and there is sensitive information on your device. eSIMs offer more security because there is no physical card to take. Activating it is controlled through your device, which provides an additional layer of security.
Compatibility Of SIMs and eSIMs
Traditional SIM cards are widely available in most countries and on any mobile device that has a SIM card slot. eSIMs are only supported by newer devices as it is a relatively modern technology. It is recommended to check if carriers in the countries you are travelling to support them beforehand.
Choosing The Right eSIM
If you have decided to use an eSIM on your upcoming travels, there are a few factors to keep in mind to get the most out of your eSIM experience.
Check Your Destination’s Coverage
Some eSIM providers have global plans which means that you can use your eSIM in multiple countries if you are visiting more than one destination or have a few stops along the way.
Data Usage
Estimate ahead of time how much data you think you may use. Video-streaming, using maps or working remotely will require more data. There are some eSIM providers that offer unlimited data plans, or different plans according to usage.
Price Of Plans
Different eSIM providers will have different costs for activation fees and data rates. Some will have pay-as-you-go options or prepaid packages. Researching providers beforehand will give you a better idea of which one will suit your needs and budget, so that you don’t spend unnecessarily.
Find Easy To Use Apps
It’s recommended to choose an eSIM provider that has an easy-to-navigate app or website for the purchase and management of your chosen plan. Travelling has its own set of challenges, and if you need customer support for your eSIM to guide you through the process, it will be one less thing to worry about.
