If you've ever needed to make a call abroad — whether to a government office, a bank, or even a friend — and didn’t want your real number to be revealed, you’re not alone. People around the world look for ways to protect their privacy while staying connected.
Maybe you’re calling from a borrowed device. Maybe you’re traveling and don’t want to expose your home SIM. Or maybe you just don’t want your personal number tied to a call you're placing internationally.
So the big question is: Can you make a secure international call from your browser — without revealing your real number?
Yes. You can.
And in this guide, we’ll show you exactly how it works.
Why Would You Want to Hide Your Real Number?
There are several perfectly valid reasons someone might want to mask their caller ID or use a different number when making a call:
- Privacy: You don’t want strangers, businesses, or agencies storing your personal number
- Travel: You’re overseas and using a temporary SIM or no SIM at all
- Verification: You're calling a service that only responds to recognized (regional) numbers
- Security: You want to avoid callbacks, harassment, or exposure to spam
Whatever your motivation, the key is finding a method that is secure, legal, and functional — especially when calling mobile or landline numbers internationally.
The Old-School Workarounds (and Why They Suck)
Most users try a few common tricks:
- Using Google Voice or Skype — but these often don't support proper spoofing or don’t work in every country
- Dialing with carrier features like
*67— which only works in limited regions and not internationally - Buying burner phones or SIM cards — expensive and clunky
- Using messaging apps — which don’t help if the other side doesn’t use the same app
These aren’t reliable, private, or scalable. What you need is a browser-based solution that lets you call anyone, anywhere — and control what number appears on their screen.
Enter Dialvia: Browser-Based Calling with Verified Caller ID Spoofing
Dialvia is a browser-based international calling platform that lets you:
- Call any mobile or landline number in 150+ countries
- Mask or spoof your real number — using a verified one of your choice
- Do it all securely, right from your browser — with no app or download required
It’s built for expats, travelers, remote workers, and privacy-conscious people who still need to make calls that connect clearly and instantly.
How Number Masking Works on Dialvia
When you create a free account on dialvia.com, you’re automatically given a public “Dialvia” number to call from. But you can add and verify your own number and set it as the Caller ID shown to whoever you're calling.
For example:
- You’re calling a UK bank from abroad
- You verify your UK number in Dialvia
- You place the call using your browser
- The bank sees your UK number — and accepts the call
The recipient won’t see your local SIM, your IP address, or your personal line — just the verified number you’ve chosen.
The Process Step-by-Step
- Sign up for a free account at Dialvia
- Verify your email and get free call credit
- Go to the Dialer, select the country and number you want to call
- Click “Call from” and either use the default public number or add your own
- Verify your number via code, then set it as your Caller ID
- Make the call — your verified number will appear to the recipient
This is called legal spoofing, and it’s 100% compliant because the number you use must be verified through your device.
What About Security?
Dialvia uses encrypted VoIP channels, browser-level mic permissions, and doesn’t track or store unnecessary data. Your calls are private, protected, and never routed through your SIM or mobile network.
You don’t need a new app. You don’t even need a SIM card. As long as you have Wi-Fi, you can call anyone in the world — with full control over what number appears on the screen.
