Verdict
The clearest difference is ads: Umi at none against eSIMify's shown. Umi also leads on monetization model (free vs free with in-app purchases). eSIMify's advantage is update cadence (every 2 days vs every 2 weeks). On price, review sentiment, in-app purchases and device support there is nothing between them.
