Yes, but you have to make sure that all phone numbers are saved in international format: country code + phone number. 2. How much data does the app use for an online call? On average, the app uses approximately 1MB/min for making a voice call. In order to benefit from the highest quality available, we advise you to use the application with a WiFi network. Any costs resulting from using the application with mobile data networks when you call internationally are not covered by us. 3. Which countries & operators support mobile top-ups? You can send top-ups to 160+ countries and mobile operators around the world. Simply browse through the list of available destinations; once you select your desired country, the available operators will be displayed. 4. What is a travel eSIM and how does it work? A travel eSIM is a digital SIM card that allows you to access mobile data in other countries without needing a physical SIM. Instead of inserting a plastic card, you download a profile to your phone. It works by connecting your device to local mobile networks in your destination country, providing you with affordable data at more cost-effective rates than traditional international roaming.

ReceptionRating · Positive reviews · Number of ratings

KeepCalling International holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: KeepCalling International has 19K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 39% of KeepCalling International's written reviews are positive against 83% of Ask Those Who Know's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

KeepCalling International ships an update every 3 weeks, Ask Those Who Know every 6 weeks. The most recent releases landed on November 3, 2026 and November 2, 2026 respectively.
