- A
Enable Airplane Mode and turn on Wi-Fi.
Why wrong: Airplane Mode disables all cellular radios, preventing calls and texts, which is not what the user wants.
- B
Disable Mobile Data entirely.
Why wrong: Disabling Mobile Data stops all data usage, but the user may still want MMS or other data services; the question specifies only data roaming.
- C
Turn off Data Roaming in the mobile network settings.
Data Roaming specifically controls cellular data while roaming; turning it off prevents data charges while voice and SMS still work.
- D
Set the network mode to 2G only.
Why wrong: Setting to 2G only limits network speed but does not disable data roaming; data could still be used and incur charges.
Question 307 of 750
Configuring Android to Avoid Data Roaming Charges Abroad
This 220-1202 practice question tests your understanding of mobile os features and tools. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 an Android phone for a user who frequently travels internationally. The user wants to ensure that data roaming is disabled to avoid high charges, but still wants to receive calls and texts while abroad. Which setting should the technician configure?
Quick Answer
The answer is to disable Data Roaming in the mobile network settings while leaving voice roaming enabled. This configuration is correct because Android separates data roaming from voice and SMS roaming; turning off only the data toggle prevents the phone from using cellular data on foreign networks, which is the primary source of high charges, while still allowing calls and texts over partner networks. On the CompTIA A+ Core 2 220-1202 exam, this question tests your understanding of Android connectivity settings and the common trap is confusing "Roaming" (which covers all services) with "Data Roaming" (which covers only mobile data). A useful memory tip is to think of it as "Data off, voice on"—you want to keep the phone connected for basic communication but block the expensive data pipe.
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
✓
Turn off Data Roaming in the mobile network settings.
Option C is correct because disabling Data Roaming in the mobile network settings prevents the device from using cellular data on foreign networks, which avoids expensive roaming charges, while still allowing voice calls and SMS (which use the cellular voice and signaling channels, not the data channel). This setting is specific to roaming scenarios and does not affect the phone's ability to connect to a visited network for non-data services.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
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 turn on Wi-Fi.
Why it's wrong here
Airplane Mode disables all cellular radios, preventing calls and texts, which is not what the user wants.
- ✗
Disable Mobile Data entirely.
Why it's wrong here
Disabling Mobile Data stops all data usage, but the user may still want MMS or other data services; the question specifies only data roaming.
- ✓
Turn off Data Roaming in the mobile network settings.
Why this is correct
Data Roaming specifically controls cellular data while roaming; turning it off prevents data charges while voice and SMS still work.

Read the scenario before looking for a memorised answer.
- ✗
Set the network mode to 2G only.
Why it's wrong here
Setting to 2G only limits network speed but does not disable data roaming; data could still be used and incur charges.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between disabling Mobile Data entirely (which kills all data, even at home) and disabling Data Roaming (which only blocks data while on a foreign network), leading candidates to mistakenly choose Option B.
Detailed technical explanation
How to think about this question
Data roaming is controlled by the 'roaming' flag in the device's APN (Access Point Name) settings and the mobile network stack; when disabled, the device's modem will not establish a PDP (Packet Data Protocol) context on a visited network, but the device still registers on the foreign network's MSC (Mobile Switching Center) for voice and SMS via SS7 signaling. In real-world scenarios, some carriers automatically enable data roaming on postpaid plans, so manually toggling this setting is critical to avoid bill shock, especially in countries where data rates can exceed $20 per MB.
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 220-1202 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.
