Verdict

The call

The clearest difference is rating: Call.com at 4.6 against Blacktel's 2.4. Call.com also leads on update cadence (every 2 weeks vs every 2 months) and monetization model (free vs free with in-app purchases). Blacktel's advantage is iOS requirement (12.0 vs 16.4). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Blacktel sells 9 in-app purchases, starting at $16.49 per month and Call.com sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
