Thailand’s largest cellco by subscribers, Advanced Info Service (AIS), announced that it reached 1.2 million 3G 900MHz network subscribers by the end of December 2011, after launching the commercial HSPA-based service in July. AIS’s closest rival operator DTAC claimed this month that its 850MHz HSPA service had attracted 1.1 million subscribers, following a full commercial network launch in August.

AIS’s 3G announcement came alongside its financial results for the year and fourth quarter, in which it reported that twelve-month revenues excluding interconnection rose 12% to THB97.9 billion (USD3.2 billion), driven by mobile internet growth, as non-voice turnover climbed 31% in comparison to an 8% increase in voice revenue. Annual EBITDA reached THB56.6 billion, up by 10%, and net profit jumped 21% to THB26.6 billion. CAPEX was raised by 18% in 2011, as the company expanded 3G and 2G coverage and capacity, and AIS claimed a total of 33.5 million subscribers at the end of December, up by 2.3 million in twelve months.
