ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Mobile OTP Authenticator ships an update every 8 months, SIM Card Status Checker monthly. The most recent releases landed on October 17, 2026 and October 19, 2026 respectively.
