Most (if not all) cellular phone carriers do not offer the full caller ID service that exists for landline phones.

This tool may only be used to research phone numbers that called you or contacted you via social media. All use must comply with applicable international, federal, and local laws.

Verdict
The clearest difference is review sentiment: Viva VPN at 88% against Caller's 42%. Viva VPN also leads on rating (4.5 vs 3.7) and update cadence (every 9 days vs every 5 weeks). Caller's advantage is ads (none vs shown) and iOS requirement (8.0 vs 15.0). On price, ratings volume, in-app purchases and monetization model there is nothing between them.
