BANGKOK (Reuters) - Shares in Thai telecoms firms skidded on Monday after the auction of two 4G spectrum licenses ended at the weekend amid investor concern at high prices and future costs and competition in the sector.
The country's largest fully integrated telecoms service provider, True Corp, and broadband operator Jasmine International Pcl were the surprise winners on Saturday of a second auction for two 4G spectrum licenses valued at 151.95 billion baht ($4.2 billion).
