# MobiSIM vs One Sim

The clearest difference is rating: One Sim at 4.9 against MobiSIM's 4.0. MobiSIM's advantage is review sentiment (100% vs 81%). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

One Sim holds the better App Store score, 4.9 against 4.0. Both are backed by a comparable volume of ratings — 4 and 10 respectively. Written reviews complicate that: 100% of MobiSIM's written reviews are positive against 81% of One Sim's, so the app with the better star average is not the one people write more warmly about.

MobiSIM ships an update every 2 weeks, One Sim weekly. The most recent releases landed on November 5, 2026 and November 6, 2026 respectively.
