After Unicom sells CDMA, what network will Unicom's 2G mobile phone use?

1 and 2G are divided into GSM and CDMA networks, both of which are patents of large foreign companies. Among them, CDMA is the core patent of Qualcomm, while GSM is held by many European companies.

2. It is not that Unicom wants to sell CDMA to telecom, but the decision of the National Development and Reform Commission and the Ministry of Telecommunications, which is beyond Unicom's control.

3.GSM has the largest network in the world, and almost all countries have this network.

4. Now Unicom's 2G network is GSM, 3G network is WCDMA, mobile 2G network is GSM and 3G network is TDSCDMA.

I don't know if you are satisfied! !
