Block Calls from Overseas? Yes, Here’s How
Yes, you can block calls from overseas, and the most effective method depends on your phone type and carrier. This article explains the different ways to stop unwanted international calls on both iPhone and Android, including built-in settings, carrier services, and third-party apps.
Why You Receive Overseas Calls
Unwanted international calls usually come from robocallers and scammers who use spoofed numbers to make it look like the call is coming from a foreign country. They often target numbers randomly, hoping to find someone who will answer and fall for a scam, such as a fake tech support call or a “grandparent scam.” Some legitimate businesses also call from overseas, but the vast majority of international calls to personal numbers are spam.
How to Block Overseas Calls on iPhone
iOS offers a simple way to silence unknown international callers, but it blocks all unknown numbers, not just overseas ones.
- Open Settings and tap Phone.
- Tap Silence Unknown Callers.
- Toggle the switch to On.
This sends calls from numbers not in your Contacts, Mail, or Messages to voicemail. It also silences calls from numbers you’ve never interacted with, so be aware that some legitimate calls may be missed.
How to Block Overseas Calls on Android
Android phones do not have a single “block all international” button, but you can block specific international numbers or use a third-party app.
- Block a specific number: Open the Phone app, tap the recent call from the international number, then tap Block/report spam.
- Use a third-party app: Apps like Truecaller or Hiya can identify and block spam calls, including international ones, based on community reports.
Carrier-Level Blocking
Many mobile carriers offer services that block international calls or spam calls at the network level. For example, AT&T has “AT&T Call Protect,” Verizon has “Call Filter,” and T-Mobile has “Scam Shield.” These services often include a free basic version that blocks spam and a paid premium version that adds features like caller ID and spam risk alerts. Contact your carrier to see what options are available.
Using Third-Party Call Blocking Apps
Third-party apps can be more flexible than built-in settings because they let you block entire country codes or use a community-based spam list. Popular apps include:
- Truecaller: Identifies unknown numbers and blocks spam calls.
- Hiya: Offers spam detection and blocking.
- RoboKiller: Uses audio responses to waste scammers’ time.
These apps typically require access to your call log and contacts, so review their privacy policies before installing.
Common Problems and Misconceptions
One common misconception is that blocking a single international number will stop all overseas calls. In reality, scammers use spoofing to change their number constantly, so blocking one number is ineffective. Another issue is that some legitimate international calls, such as from a bank or a relative abroad, may be blocked by aggressive filters. To avoid missing important calls, consider whitelisting contacts you know.
How to Choose the Best Method
Consider your needs when choosing a blocking method:
- If you rarely get international calls: Blocking individual numbers as they appear is sufficient.
- If you get many spam calls: Use a carrier service or third-party app.
- If you want to block all unknown callers: Use the iPhone’s Silence Unknown Callers feature.
Safety and Privacy Considerations
When using third-party apps, be aware that they may collect your call data. Always read the app’s privacy policy and only grant permissions that are necessary. Additionally, never give personal information to unknown callers, even if they claim to be from a legitimate company. Hang up and call the official number to verify.
Frequently Asked Questions
Will blocking overseas calls also block legitimate calls from abroad?
Yes, if you use a method that blocks all international numbers, you will also block legitimate calls from friends, family, or businesses outside your country. To avoid this, you can whitelist specific contacts or use an app that allows you to block only certain country codes.
Can I block calls from a specific country code?
Some third-party apps allow you to block calls from specific country codes. For example, you can block all numbers starting with +44 (UK) or +91 (India). Built-in phone settings do not offer this level of control.
Do carrier services cost money?
Most carriers offer a free basic spam-blocking service. Premium features, such as advanced caller ID and spam risk alerts, may require a monthly fee. Check your carrier’s website or app for details.
Will blocking overseas calls stop all spam calls?
No, because scammers can also use local numbers or VoIP to make calls that appear domestic. Blocking overseas calls reduces the volume but does not eliminate all spam.
Is it safe to answer an overseas call?
It is generally safe to answer, but do not provide any personal information. If the caller claims to be from a company, hang up and call the official customer service number to verify. Never share passwords, PINs, or financial details over the phone.
