The difference between promotional period and SIM validity period
Have you ever wondered about that question? Many customers use 3G SIMs but do not distinguish between these two terms. Perhaps there is no clear concept of SIM usage period and promotional period. To explain this question, we can simply explain it as follows:

Promotional period:
is the time customers enjoy the promotion of the SIM from the date the customer activates the SIM package. It is usually 12 months. After 12 months, the customer's SIM will return to its normal state and will not enjoy the initial package promotion. Charges will be calculated according to the network operator's charges.
