eSIM is short for embedded SIM<\/strong>, a programmable SIM card<\/strong> that is permanently installed in the device. Instead of inserting a regular plastic SIM card, with eSIM a digital SIM profile (\u201cprofile\u201d) is loaded onto an eUICC chip in the smartphone\/tablet\/smartwatch. This profile contains exactly the same information as a standard SIM card (e.g., IMSI, authentication key), only it all works digitally.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

In our experience, an eSIM is one of the most practical and affordable ways to stay connected while traveling, without high roaming charges, complicated SIM card changes, or complicated activations. It makes international travel much easier, more flexible, and often more sustainable.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

No expensive roaming charges<\/strong><\/p>

With a travel eSIM, you can use local data plans instead of roaming on your regular cell phone contract.<\/p>

This means you don’t have to worry about high roaming charges and have full control over your costs. You only pay for what you actually use and are not tied to a long-term contract.<\/p>

Instant online access with mobile data<\/strong><\/p>

You can purchase and activate your eSIM before you leave or install it right after you land. If you install your card before your trip, you’ll save yourself the hassle of waiting in line at the airport shop, changing cards, and the risk of losing your card.<\/p>

With an eSIM, you can store multiple profiles on your smartphone<\/strong>.<\/p>

You can<\/span>:<\/p>

keep your home number (for text messages or calls)
and activate a local eSIM for data.<\/p>

This way, you can still be reached on your normal cell phone number, but use affordable data packages.\u00a0<\/p>

Faster, more stable internet access worldwide<\/strong><\/p>

Saily works with the largest local mobile networks, which usually have very well-developed networks, such as Claro, Vodafone, Movistar, or AT&T. Saily usually chooses the best covered and fastest network.<\/p>

Greater security when traveling<\/strong><\/p>

An eSIM cannot be stolen or lost because it is permanently installed in the device.<\/p>

Furthermore, Saily uses integrated security features such as ad blockers, VPN, and phishing protection.<\/p>

Sustainable & environmentally friendly<\/strong><\/p>

Since no physical card is sent or produced, there is no plastic waste and the cards do not have to be transported.
This saves resources, especially for frequent travelers who would otherwise regularly buy new local SIM cards.<\/p>

Easy management via apps<\/strong><\/p>

Travel eSIMs can be managed in just a few minutes directly via an app:<\/p>

Check data volume,
extend or change your plan,
activate automatic top-up,
get support via chat.<\/p>

Flexible data plans for any length of trip<\/strong><\/p>

Whether it’s a weekend getaway, a business trip, or a trip around the world, Saily offers eSIMs with<\/p>
