1. Number of users: The number of users of China Unicom is relatively small, while the number of users of China Telecom is relatively large, which may lead to the advantage of China Telecom in package pricing.
2. Patent fee: Telecom may pay a higher patent fee because the technology it uses may involve more patent authorization.
3. Module cost: Telecom can only use the baseband module in Qualcomm, which is expensive, resulting in a relatively high package price.
4. Competitiveness: China Unicom's 3G WCDMA system is widely used in the world, and most mobile phones in the market support this system, so China Unicom has the capital to maintain a high level of package price. 3G CDMA2000 supports relatively few mobile phones, so in order to improve competitiveness, only more preferential packages can be provided.
The above are only possible factors, and the specific situation may be different due to factors such as region, time and market strategy.
