Verdict
The clearest difference is rating: SIMPlus at 3.6 against IKOS SMS's 1.0. SIMPlus also leads on review sentiment (41% vs 0%) and update cadence (fortnightly vs every 5 months). IKOS SMS's advantage is in-app purchases (none vs 10). On price, ads, device support and iOS requirement there is nothing between them.
