An eSIM is the technology that has evolved from the traditional physical SIM cards you had to insert into your smartphone to have an internet connection and an active line. The main difference between the two types of cards is that an eSIM is integrated into your device at the hardware level, and there's no need to handle any physical card for it to work, as it's activated by scanning a QR code.
For frequent travelers, the arrival of eSIMs on the market has been key in terms of security and convenience. The reason is that if you choose a specialized eSIM provider for traveling, you completely eliminate the cost of roaming charges. You also enjoy other benefits, such as instant activation and the possibility of enjoying much more competitive rates. In this article, we compare two of the main eSIM providers: Ubigi and Airalo.

As mentioned above, it offers coverage in more than 180 countries worldwide with excellent stability. The plans offered vary by region, and you can choose between plans for a one-time trip, perfect for travelers, or annual plans, which are recommended for those who travel frequently and are especially designed for the work environment.
