The National Broadcasting and Telecommunications Commission has decided to impose a cap on the number of SIM cards that each individual subscriber can buy.

NBTC secretary-general Takorn Tanthasit said that under the new measure endorsed by the regulator, each individual subscriber can buy a maximum of five SIM cards from each of the mobile phone service providers.

If the subscriber wants to buy more than five SIM cards, he or she must buy the additional cards at the service centres of the service providers who will be required to report the purchases to the NBTC office.

The new measure also calls for a condition to be put in the contract between mobile phone service providers and their sale agents mandating the service providers to be liable to civil litigation toward their subscribers for the actions undertaken by their sale agents.
