How can I activate it easily?

The standard procedure requires the user to have an active internet connection via Wi-Fi to download the information from their contracted service provider.

The customer receives a printed or digital QR code containing the encrypted parameters necessary to validate the new profile.

The process is simple, although it crucially depends on the stability of your local network at the time of pairing.

Access the network settings menu of your mobile operating system and select the indicated option to add a new cellular plan.

Point your device's camera at the code you received and wait for the automatic data processing, which takes a few seconds.

The process is intuitive, eliminating the need for human technical support for tasks that should be purely automated.

Some phone companies already offer the direct provisioning process through their official apps, eliminating the need for validation images.

If you switch devices, simply remove the digital profile from the old device before scanning it on the new smartphone.

Losing your old phone without backing it up requires a bureaucratic visit to the service provider, a technical detail overlooked by many.

++ Technologies that help you sleep better: what really works?

Which smartphones already support this technology?

The transition to a purely digital ecosystem began with premium models, but is rapidly advancing towards the most popular mid-range devices on the market today.
