eSIM 20 GB for 30 days in Portugal

An eSIM is a digital SIM card that has no physical form. It is embedded into a mobile device (such as a smartphone or tablet) that supports this technology and serves as a modern alternative to the traditional plastic SIM card. To use an eSIM, you need to connect to a mobile network operator.

Most modern mobile devices support eSIM technology, including models from both premium and budget segments. To check whether your smartphone is compatible with eSIM, refer to the official website of the device manufacturer.

Yes, this allows you to use one for personal needs and another for work, for example. It’s also convenient when traveling across multiple countries. However, the number of eSIMs that can be stored and used simultaneously depends on the specific device. You can find this information on the manufacturer’s website or by contacting technical support.

Just like a regular physical SIM card, eSIM allows you to connect to a mobile operator’s network, access the internet, use email, apps, online games, and popular messengers for quick messaging or calls. It is a full-fledged replacement for traditional SIM cards. However, it’s important to note that travel eSIMs work a bit differently: they don’t have their own phone number and provide mobile internet only. This means you can freely use messengers — make calls, send messages, and share files as usual. However, regular phone calls and SMS via the mobile network will not be available, since these plans are designed exclusively for internet access.
