$100 Airtime Question | Technical service details | Consumer forum

If you buy four $25 airtime (total $100) & get the free Nokia 1600 phone. Will you be able to spread out the four $25 airtime voucher for 4 yrs? Is there an expiry date that the airtime voucher needs to be used or loaded?

Bec I'm not a heavy phone user. So, refilling the air time each year for $25.

Let me know...thanks in advance.
