【电信定制机与移动定制机的区别】Telecom custom phones usually support both GSM and CDMA networks, but only have CDMA 1x and CDMA EV-D0 capabilities. Mobile custom phones, on the other hand, do not consider the issue of supporting CDMA and GPRS in 3G networks. Therefore, if you want to use a telecom custom phone with a mobile network, it won't work due to compatibility issues. However, if you need to use a mobile custom phone, you should consider using a Telecom CDMA card instead, which is supported by the mobile network.
【电信和移动网络的区别】The main difference between telecom, mobile, and联通 networks lies in their 2G and 3G standards:
Mobile has a 2G network based on GPRS (General Packet Radio Service) and a 3G network based on TD-SCDMA (Time Division-Synchronous Code Division Multiple Access).
Telecom has a 2G network based on CDMA 1x and a 3G network based on CDMA EV-D0.
Unicom has a 2G network based on GPRS and a 3G network based on WCDMA (Wideband Code Division Multiple Access).
So, it's important to note that mobile custom phones cannot be used with telecom CDMA cards, while telecom CDMA cards can be used with mobile custom phones.
