Tourist SIM and eSIM: maximum validity from activation
This is why a long-stay resident cannot simply keep the line they arrived on. The tourist product expires on its own schedule regardless of how long the person stays, which forces a move to a registration-card line — and anyone who registered the temporary number with a bank, a school or an employer has to change it everywhere at the same time.
- Applies to

Counted from first activation. Other carriers and resellers set their own limits, so confirm the product you actually buy. The practical consequence is the same everywhere: the arrival line is temporary by design.
