FAQ

How many lines are needed to qualify for a family discount?
Most carriers apply discounts starting from the second line. The definition of 'family' varies — some require the same address, others only require the same account holder or payment method. Check eligibility criteria on the carrier's site.
Can I sign up a child (minor) for a budget SIM?
Minors typically require a parent or guardian as the account holder or a written consent form. Some carriers require in-person verification for minor applications. Check the carrier's minor application policy before choosing.
Are there shared data plans for families?
Some carriers offer shared data pools where a parent line subscribes to a large data plan and distributes it among family members. This can be more economical when usage patterns vary widely among family members.
