- A
Enable airplane mode and then turn on Wi-Fi.
Why wrong: While this works, it is a two-step process that the user might forget. Disabling cellular data is a simpler, more direct setting.
- B
Disable cellular data in the mobile network settings.
This stops all cellular data usage while allowing Wi-Fi to remain active, preventing roaming charges when connected to Wi-Fi.
- C
Enable data roaming.
Why wrong: Enabling data roaming would actually increase the risk of high roaming charges, contrary to the user's goal.
- D
Set the device to 2G only.
Why wrong: This reduces data speed but still uses cellular data, which could incur roaming charges.
Question 63 of 1,020
How to Use Wi-Fi Only While Traveling Internationally
This 220-1201 practice question tests your understanding of mobile device network connectivity. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is configuring a smartphone for a user who frequently travels internationally. The user wants to avoid high roaming charges but still use data when connected to local Wi-Fi. What should the technician do?
Quick Answer
The answer is to disable cellular data in the mobile network settings. This is the correct choice because it physically cuts the smartphone’s connection to the mobile carrier’s network, forcing all data traffic to pass exclusively through Wi-Fi. When traveling internationally, leaving cellular data active can trigger expensive roaming charges the moment the device connects to a foreign tower, even if the user intends to rely solely on local Wi-Fi. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of mobile network configurations and data cost management—a common trap is confusing Airplane Mode with disabling cellular data, since Airplane Mode also kills Wi-Fi and Bluetooth, which the user still needs. A reliable memory tip is to think “Cut the cell, keep the Wi-Fi spell”—disabling cellular data is like turning off the mobile faucet while leaving the Wi-Fi pipe open, ensuring you avoid roaming charges without losing internet access.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Disable cellular data in the mobile network settings.
Option B is correct because disabling cellular data in the mobile network settings prevents the device from using the carrier's mobile data network, thereby avoiding roaming charges. The user can still connect to local Wi-Fi networks for data access, as Wi-Fi operates independently of the cellular data radio. This approach ensures that no data is transmitted over the cellular network while traveling internationally.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
This reduces data speed but still uses cellular data, which could incur roaming charges.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse disabling cellular data with enabling airplane mode, not realizing that airplane mode also disables Wi-Fi and voice services, whereas disabling cellular data specifically targets data connectivity while preserving other functions.
Detailed technical explanation
How to think about this question
Under the hood, disabling cellular data in the mobile network settings sets a software flag that prevents the device's modem from establishing a Packet Data Protocol (PDP) context for data services, while keeping the voice and SMS radios active. This is distinct from airplane mode, which disables all radio frequency (RF) transceivers. In real-world scenarios, a user might need to receive calls or SMS for two-factor authentication while abroad, making this option preferable to airplane mode.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
