- A
Check if the date and time are set correctly on the iPhone.
Why wrong: Incorrect date/time can cause SSL errors, but this would typically affect Safari and email as well, which are working.
- B
Verify that the Apple ID is signed in and has no payment issues.
App Store downloads require a valid Apple ID; if the account has an outstanding balance or is not signed in, downloads will fail.
- C
Reset the iPhone's network settings.
Why wrong: Network settings reset would affect Wi-Fi and other connectivity, but internet is already working for other apps.
- D
Check if the iPhone is in Low Power Mode.
Why wrong: Low Power Mode does not block App Store downloads; it only reduces background activity.
Question 642 of 1,020
iPhone Cannot Install or Update Apps from App Store
This 220-1201 practice question tests your understanding of mobile device application support. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 troubleshooting an iPhone that cannot install or update any apps from the App Store. The device is connected to Wi-Fi, and other internet services (Safari, email) work. What should the technician check first?

Quick Answer
The answer is to verify that the Apple ID is signed in and has no payment issues. This is the correct first step because when an iPhone cannot install or update apps from the App Store, yet other internet services like Safari and email work fine, the problem is isolated to the App Store’s authentication layer rather than network connectivity. The App Store requires a valid, signed-in Apple ID with no outstanding payment holds or billing problems to authorize downloads, even for free apps. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests advanced mobile device troubleshooting, specifically distinguishing between network-level and account-level failures. A common trap is to immediately check Wi-Fi settings or date/time, but since other internet services function, the issue must be account or restriction-based. Remember the mnemonic “APP Store” — Account, Payment, Permissions — to recall the first three things to verify when downloads fail despite a working internet connection.
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
✓
Verify that the Apple ID is signed in and has no payment issues.
Option B is correct because the most common cause for an iPhone being unable to install or update apps while other internet services work is an issue with the Apple ID, such as a payment method that has expired or a billing problem. The App Store requires a valid payment method on file even for free apps, and the device will block downloads until the account is resolved. Since Safari and email function normally, the network connectivity is fine, narrowing the issue to account authentication or authorization.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The 220-1201 exam often tests the misconception that network connectivity issues are the root cause when only one service fails, but the trap here is that candidates overlook account-level restrictions that are specific to the App Store's authentication and payment validation process.
Detailed technical explanation
How to think about this question
The App Store uses Apple's iTunes Store authentication service, which validates the Apple ID's payment method via a token exchange with Apple's servers. Even for free apps, the system performs a zero-amount authorization to ensure the account is in good standing; if the payment method is expired or has a billing issue, the server returns a 'payment required' error that the device interprets as a download failure. This is distinct from general network connectivity, which relies on HTTP/HTTPS and DNS resolution—both of which work here.
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 junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
