NAKED offers an eSIM option for compatible devices, and the provided page states that users can activate the eSIM in under three minutes. This can be convenient because an eSIM does not require a physical SIM card to be inserted into the phone. NAKED also provides a step-by-step How-It-Works section covering the downloading and activation process. When signing up, users can either keep their existing phone number or get a new one. The activation is presented as costing ¤0, which fits the company's broader approach of keeping the mobile service transparent. Users can find more information about the eSIM and other NAKED services athttps://naked.net/. The service also lists additional features such as LTE/5G, D-Netz connectivity, WiFi-Calling, and EU roaming. Of course, the phone must support eSIM technology for this option to work. It is therefore worth checking device compatibility before registering. For someone with a compatible smartphone, the stated activation time of under three minutes makes the setup process relatively straightforward. The eSIM is part of the wider NAKED model rather than a separate prepaid product.
