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.

Verdict

The call

The clearest difference is in-app purchases: Pi, your personal AI at none against KeepCalling International's 15. Pi, your personal AI also leads on ads (none vs shown) and update cadence (every 2 days vs every 3 weeks). KeepCalling International's advantage is rating (4.6 vs 4.4) and ratings volume (19K vs 2.5K). On price, device support and iOS requirement there is nothing between them.

Both are free to download. KeepCalling International sells 14 one-off in-app purchases. Pi, your personal AI asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

KeepCalling International holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: KeepCalling International has 19K ratings behind it against 2.5K, so its average is the more settled of the two. Written reviews complicate that: 39% of KeepCalling International's written reviews are positive against 60% of Pi, your personal AI'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, Pi, your personal AI every 2 days. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
