# CallOn vs eSIM Internet Data

The clearest difference is rating: CallOn at 5.0 against eSIM Internet Data's 4.1. CallOn also leads on review sentiment (100% vs 73%) and update cadence (every 11 days vs every 2 months). eSIM Internet Data's advantage is ratings volume (32 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. CallOn sells 6 one-off in-app purchases and eSIM Internet Data sells 7 in-app purchases, starting at $2.49 per month. Whichever you choose, the download price is not the number that matters.

CallOn holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: eSIM Internet Data has 32 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of CallOn's written reviews are positive against 73% of eSIM Internet Data's.
