Verdict
The clearest difference is rating: Yabb ESIM at 4.3 against 1SIM eSIM's 3.2. Yabb ESIM also leads on review sentiment (94% vs 67%) and update cadence (fortnightly vs every 3 months). 1SIM eSIM's advantage is in-app purchases (none vs 10) and iOS requirement (13.0 vs 16.0). On price, ads and device support there is nothing between them.
