eSIM NAVI vs KeepSim

eSIM NAVI is a free guide app that helps you set up an eSIM you've already purchased on your iPhone — in just a few taps. KEY FEATURES QR scan auto-launches iPhone's eSIM setup Just scan the QR code from your purchase email. No typing activation codes, no jumping between apps — your iPhone's "Add eSIM" screen opens for you. 18 illustrated setup guides Step-by-step guides for iPhone and Android (multiple manufacturers), plus common troubleshooting and error-message references — all written for non-technical users. Japanese & English Choose your language at first launch or switch anytime. Built for travelers and international users. Built-in chat support Stuck on a step? The in-app assistant answers your questions instantly. Fallback for older devices On older iOS versions or custom Android devices where auto-launch isn't available, the app shows a manual setup screen with copy-ready codes. This app does NOT sell or issue eSIM plans. It is a setup-assistance tool for users who have already received a QR code or activation code (typically by email after purchasing an eSIM from another service). REQUIREMENTS - iOS 15.1 or later - An eSIM-capable iPhone (iPhone XR / XS or newer) - iOS 17.4+ for full auto-launch support CONTACT support@esimnavi.info

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.
