Which of the following cellular technologies should the administrator look for in the phone?

GSM

D.

B.

When a mobile phone needs to make and receive calls in multiple countries outside of North America, the network administrator should look for a phone with the GSM (Global System for Mobile Communications) cellular technology.

GSM is a standard cellular technology used by most mobile carriers worldwide, and it is compatible with most international cellular networks. It operates using a SIM (Subscriber Identity Module) card, which stores the user's phone number and account information.

CDMA (Code Division Multiple Access), TDMA (Time Division Multiple Access), and CSMA (Carrier Sense Multiple Access) are all cellular technologies that were primarily used in North America and are not as commonly used internationally. While some international carriers may support these technologies, it is much more likely that they will use GSM or a newer technology such as 4G or 5G.

Therefore, for a mobile phone that needs to work in multiple countries outside of North America, the administrator should choose a phone with GSM technology to ensure compatibility with most international cellular networks.
