TD-LTE 4G licences issued by the government favored China Mobile, since TD-LTE technology was compatible only with the market leader's homegrown 3G standard unlike China Unicom and China Telecom, whose 3G networks were based on the internationally accepted WCDMA standard. This allowed China Mobile to race past rivals in 3G/4G subscriber adds in the first quarter this year, adding over 36 million new high speed users (3G & 4G) compared to about 10 million and 1 million adds for China Unicom and China Telecom, respectively. However, it is evident from this data that despite China Mobile's first mover and network compatibility advantage, China Unicom made substantial progress in improving its high speed subscriber base. It should also be noted that its performance in terms of user additions was far better than its smaller rival China Telecom.
