SimTap: SIM & Number Manager

Give every phone number a little peace of mind.

SimTap keeps your mobile and virtual numbers in one place, with personal reminders for the actions that help you maintain them. Whether you keep a spare SIM, travel with several numbers, or manage a number abroad, you can see what needs attention and when.

A CLEAR HOME FOR YOUR NUMBERS
Save the number, country or region, provider, nickname and notes. Search your list, focus on upcoming tasks, and archive numbers you no longer use without losing their history.

REMINDERS THAT FIT EACH NUMBER
Create separate top-up, SMS and call schedules. Repeat by calendar days or months, choose a first due date, and receive local notifications before a task is due. Reminder dates keep the time zone in which the schedule was created.

RECORD IT, THEN MOVE ON
Complete an action in your preferred app, then record the date and an optional note in SimTap. The next due date updates from that activity. Review your history or undo a record when needed.

UNDERSTAND YOUR PLAN COSTS
Save plan details, currency, price and billing cycle. Compare estimated monthly and annual costs for monthly, yearly or custom schedules. Amounts stay in their original currency; estimates are not bills and do not include currency conversion.

USEFUL SHORTCUTS
Open your saved top-up page, the system message composer, a phone call, or Google Voice where available. You stay in control of the sending number, message and payment.

YOUR DATA, YOUR CONTROL
Use your saved numbers and history offline. Export and import a JSON backup, and choose whether phone numbers appear in notifications. No app account, advertising, analytics SDK or subscription. SimTap is free to download; Unlimited Numbers, an optional one-time in-app purchase, unlocks unlimited numbers.

Made for iPhone and iPad, with English and Simplified Chinese, Dark Mode and Dynamic Type.

SimTap provides personal reminders, not carrier guarantees. Check your provider's current rules and account notices. The app does not automatically send messages, make calls or top up your balance. Carrier and third-party service charges may apply. Notification permissions, Focus settings and system limits can affect reminders; open the app regularly to refresh them. Backups contain your saved data as plain text and should be kept private.
