Calling cards have been around for decades and work by giving you prepaid credit that you can use from any phone. You dial an access number, enter a PIN, and then dial your international number.

• ✅ Rates can be very competitive for specific routes like US to Mexico or UK to India.
• ✅ You do not need an internet connection since calls go through regular phone lines.
• ⚠️ Watch out for hidden fees including connection charges, weekly maintenance fees, and rounding that bills partial minutes as full minutes.
• ⚠️ Unused balance often expires after 30 to 90 days of inactivity.

An eSIM is a digital SIM card that you can activate on your phone to get mobile data in foreign countries without visiting a store or swapping physical cards. Once you have data, you can use VoIP services or messaging apps to make calls.

• ✅ You can purchase and activate an eSIM before you travel so you have data the moment you land.
• ✅ There is no need to find a local shop or deal with tiny SIM card trays.
• ⚠️ eSIM plans provide data only, so you will still need a separate calling solution like HelloAirDial or WhatsApp.
• ⚠️ Not all phones support eSIM, so check your device compatibility first.

Most mobile carriers like AT&T, Verizon, and T-Mobile offer international calling add-ons that give you reduced rates or a bundle of minutes for a monthly fee. These plans let you dial international numbers directly from your regular phone app.

• ✅ Convenient if you frequently call the same country and want everything on one bill.
• ✅ You can dial from your contacts list without switching apps or opening a browser.
• ⚠️ Per-minute rates are typically higher than VoIP services even with the add-on.
• ⚠️ You need to activate the plan before traveling, and forgetting to do so can result in expensive roaming charges.

Apps like WhatsApp, Viber, and Skype let you make voice calls over WiFi or mobile data. These work well when both you and the person you are calling have the same app installed.

• ✅ Calls between app users are completely free, no matter where you are in the world.
• ✅ Most people already have WhatsApp or similar apps on their phone.
• ⚠️ Call quality depends heavily on both parties having a stable internet connection.

Traditional international calls travel through multiple telephone carriers, each taking a cut along the way. A call from the US to India might pass through three or four carriers before reaching its destination, with each one adding to the final cost.

VoIP services bypass most of this infrastructure. Your voice converts to data packets using WebRTC technology, travels over the internet to a gateway near your destination, and only then enters the local phone network. This shorter path through the traditional system translates directly to lower prices.

The difference in pricing is substantial. Calling India from a US carrier typically costs $1.00 to $3.00 per minute without an international plan. The same call through HelloAirDial costs around 2 to 3 cents per minute. A 30-minute call drops from $60 or more to under $1.

Rates vary by destination. Calls to Canada, UK, and Western Europe are generally the cheapest, often around 1 to 2 cents per minute. Calls to mobile phones in developing countries tend to cost more than calls to landlines in the same country, due to how local carriers structure their fees. You can check exact rates for any destination on the rates page before you call.

Modern VoIP services use the Opus audio codec, which adapts to your connection quality in real time. If your internet speed drops, the codec reduces audio quality slightly to maintain a stable connection rather than dropping the call entirely. On a decent WiFi or 4G connection, call quality matches or exceeds traditional phone calls.

The key requirement is a stable internet connection with at least 100 kbps of bandwidth in each direction. Public WiFi can work, though a personal hotspot or home connection will give more consistent results for important calls.

• ✈️ Travelers — Contact your bank, insurance, or government offices back home. Toll-free numbers do not work overseas, but VoIP lets you call at cents per minute instead of carrier roaming rates. See our guides for calling from India or the Philippines.
• 👨‍👩‍👧 Family overseas — Reach elderly parents or grandparents on their landline. They do not need WhatsApp or a smartphone. Their phone rings like any normal call.
• 💼 Sales and recruitment — Call international prospects, candidates, or partners at affordable rates. Works from any laptop browser without installing software.
• 🏨 Travel agencies — Coordinate with hotels, tour operators, and local vendors in any country without racking up phone bills.
• 🚨 Non-emergency support — Reach embassies, insurance hotlines, or local services while abroad. Note: VoIP cannot dial 911, 999, or 112.

• 🏠 Why landlines matter — Banks, government offices, and elderly family members often only have landline numbers. Messaging apps cannot reach them.
• 💰 Often cheaper — Landline rates are typically lower than mobile rates because termination fees are smaller in most countries.
• 📞 Dialing format — Use + followed by country code, area code, and number. Example: +44 20 7946 0958 for a London landline. Drop the leading zero from the local format.
• 🔧 VoIP handles formatting — Select the country, enter the number as it appears locally, and the system adds the correct codes automatically.
