KeepSim helps you keep every important SIM, eSIM, and virtual phone number alive — a local-first tracker for numbers you can't afford to lose. Some numbers matter long after you stop using them daily — a 2FA SIM, a prepaid travel line, a backup work number, a virtual line you can't lose. Miss the keep-alive window once and reactivation becomes a multi-step headache. KeepSim puts every number in one panel so you see what needs attention before it's gone. HOW KEEPSIM HELPS YOU KEEP EVERY SIM ALIVE > One-tap actions you set up once Pre-configure SMS, call, or web actions per number. When a renewal window opens, launch from detail or a widget — iOS confirms before anything sends. > Home Screen + Lock Screen widgets, every size Home Screen small / medium / large, plus Lock Screen rectangular / circular / inline. Top-N at-risk numbers visible at a glance; tap to jump straight to that number — no "open the app first" step. Widgets refresh after every keep-alive. > The app icon itself changes (Pro) 5 dynamic app icon styles (Poker, Calendar, Solari, LCD, Classic SIM). The KeepSim icon on your Home Screen — not a widget — shows days left for your most urgent number. Glance and you know whether to act. > Mark a keep-alive complete in one tap After the SMS sends or the call ends, mark it done. KeepSim recalculates the next due date and refreshes widgets and app icon. > Masked display across every surface Numbers display partially masked across the list, detail, and widgets. Check status in public without exposing the full number. > Local-first, no number reselling, no auto-messaging Your data lives on your device, or in your own private iCloud account if you enable Pro sync. Every communication action goes through iOS so you confirm before sending. KeepSim never auto-sends SMS or auto-dials. BUILT FOR MULTI-NUMBER USERS • Track every SIM, eSIM, prepaid line, and virtual number in one panel • Set keep-alive cycles, due dates, and reminder timing • Sort by risk — the most urgent number is always on top • Interface in English, Chinese, Japanese, Korean, and more; light and dark mode WHAT YOU GET FREE Download and use, no sign-up, no contact list access: • Up to 2 numbers • Default Kairo SIM Objects theme (light / dark / Dynamic Type) • Reminder 3 days before due • 1 basic action per number (SMS / call / web) • All Home Screen + Lock Screen widget sizes • Masked display and local storage KEEPSIM PRO — ONE-TIME UNLOCK If you manage more than a couple of numbers, Pro covers the real workload: • Unlimited numbers — track as many as you carry • Multi-stage reminders — 7 days, 3 days, and 1 day before due • All themes — Mission Timer Cards, Aero Operations Ledger, Telecom Command Console, and more, syncing across app and widgets • 5 dynamic app icons — Poker, Calendar, Solari, LCD, Classic SIM. The KeepSim icon shows days left for your most urgent number, refreshing after each keep-alive • iCloud sync — keep your numbers consistent across iPhones and iPads via your own iCloud; KeepSim's servers never see your data One-time purchase. Restore Purchases works on new devices. No subscription, no auto-renewal. WHAT KEEPSIM DOESN'T DO Clear boundaries, no surprises: • We don't sell or trade phone numbers • We don't provide carrier service or manage your carrier account • We don't auto-send SMS or auto-dial — every action requires your confirmation through iOS • We don't upload your numbers to our servers; data lives on your device or your private iCloud • We don't track you, we don't include ad SDKs, we don't read your contacts WHO KEEPSIM IS FOR • Students abroad and people working across borders • People holding on to a home-country SIM, a travel eSIM, or a prepaid line they can't afford to lose • Multi-line workers juggling work, backup, and virtual numbers • Anyone with a 2FA-only number that must stay alive Keep every number alive before it slips off your radar.
