The clearest difference is ads: Constella Mobile at none against ProntoSIM's shown. Constella Mobile also leads on monetization model (free vs free with in-app purchases). ProntoSIM's advantage is update cadence (every 9 days vs every 2 months) and iOS requirement (15.1 vs 17.5). On price, rating, review sentiment and ratings volume there is nothing between them.
