5. TOT Plc is spending 50 million baht to improve its pay telephones to accommodate new coins. The state enterprise expects to modify 40,000 telephones across the country by early next year and 200,000 by year-end next year. TOT president Varuth Suvakorn said the improvements became necessary after the Treasury Department minted new one-, two-, five- and 10-baht coins, changed the metal used in the one- and two-baht coins and changed the weight and density of the five-baht coin. The new coins were released in August, and some TOT pay phones were unable to accommodate them.
