Activation is a core skill every device repair specialist should master.

This step unlocks the phone’s ability to make calls, send texts, and use data over cellular networks.

This typically occurs when the device is powered on for the first time or after a factory reset.

Don’t confuse activation with unlocking; they serve entirely different purposes.

The system will direct the user to a setup screen to authenticate with the carrier.

The carrier verifies the IMEI against its database to validate ownership and اکتیو دانگل eligibility.

Clear guidance can prevent unnecessary returns and customer frustration.

Having troubleshooting steps documented improves efficiency and service quality.

Avoid assuming a broken component just because the device won’t activate.
