China Telecom and mobile phone manufacturers will launch more than 80 dual-card "Full Netcom" mobile phones nationwide, which are compatible with the networks of China Telecom, China Mobile and China Unicom, and can be inserted into any number cards of China Telecom and other two operators at the same time. Both number cards can make phone calls and surf the Internet. China Telecom made the three operators "converge" on the mobile phone through this mobile phone.
For a long time, it is not uncommon for a person to have multiple mobile phone numbers with two mobile phones due to the differences of carrier networks. However, the "two-gun general" makes people feel very inconvenient.
In order to solve the problem that one person has two or even three mobile phones, China Telecom has launched a full range of all-netcom mobile phones with different price segments and different configurations. With such a full netcom mobile phone, you can not only use Tianyi network for online entertainment, but also truly realize the "integration of the three operators" on the mobile phone.
As we all know, Qualcomm is the most well-known mobile phone chip manufacturer, but in fact it is also a "patent tycoon". Among them, the 2G CDMA system used for telephone calls involves the patent of Qualcomm, while China Mobile Unicom adopts GSM system, and the standard of GSM system is not from Qualcomm.
Therefore, every time a mobile phone manufacturer sells a mobile phone that supports telecommunications, it needs to pay a patent fee to Qualcomm. In view of the fact that there are not many users who need to use two telecom cards at the same time, and the manufacturer pays less for a telecom baseband patent fee due to various considerations such as cost, the current mobile phone cannot support the simultaneous use of two telecom cards, even full netcom.
People's Network-Telecom's whole netcom mobile phone dual card dual standby can make calls and surf the Internet.
