# Mobile OTP Authenticator vs SIM Card Status Checker

The clearest difference is rating: SIM Card Status Checker at 4.7 against Mobile OTP Authenticator's 3.5. SIM Card Status Checker also leads on update cadence (monthly vs every 8 months) and ratings volume (881 vs 2). Mobile OTP Authenticator's advantage is in-app purchases (none vs 18) and ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. SIM Card Status Checker sells 18 one-off in-app purchases. Mobile OTP Authenticator asks for nothing beyond the download.

SIM Card Status Checker holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: SIM Card Status Checker has 881 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Mobile OTP Authenticator's written reviews are positive against 81% of SIM Card Status Checker's, so the app with the better star average is not the one people write more warmly about.
