Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Enable airplane mode and then turn on Wi-Fi.

  Why it's wrong here

  Enabling airplane mode disconnects the cellular radio, preventing any mobile-network roaming charges, but the user still needs mobile data when away from Wi-Fi. This fails the scenario because the user requires data connectivity outside Wi-Fi zones, and airplane mode blocks all cellular data. It is tempting because it is the correct method to eliminate roaming charges entirely when the user can rely solely on Wi-Fi, such as in a hotel or office with consistent coverage.

• ✓

  Disable cellular data in the mobile network settings.

  Why this is correct

  Disabling cellular data in the mobile network settings is the precise solution because it completely prevents the device from using the cellular network for internet access, thereby eliminating the possibility of incurring data roaming charges. This setting allows the smartphone to continue connecting to Wi-Fi networks for data, ensuring the user maintains internet connectivity when available, without any risk of unexpected costs from mobile carriers when outside their home network. This configuration effectively manages data usage by restricting it to Wi-Fi only, satisfying the requirement to avoid roaming fees.

• ✗

  Enable data roaming.

  Why it's wrong here

  Enabling data roaming explicitly permits the smartphone to connect to cellular networks operated by partner carriers in foreign regions, which is precisely where high roaming charges are incurred. This setting is designed to provide cellular data connectivity when outside the home network, but it comes with significant per-megabyte costs that the user is trying to avoid. Therefore, activating this feature would directly contradict the objective of preventing unexpected mobile expenses.

• ✗

  Set the device to 2G only.

  Why it's wrong here

  Setting the device to 2G only merely restricts the cellular radio to the slowest available generation of mobile network technology, such as GPRS or EDGE. While this might reduce the *amount* of data consumed due to slower speeds, it does not disable cellular data connectivity altogether. Consequently, the device would still actively use the cellular network for data, making it susceptible to incurring roaming charges, albeit potentially at a slower rate, which fails to meet the user's primary goal of preventing such fees.
