iOS 1.8 is now available · Batch import, trip organization, and staged setup

Manage every trip with eSIM of your choice

Not tied to any single eSIM brand. You can compare and choose a plan that fits your budget and trip, then use eSIMManager to organize multiple cards, activation information, and expiration dates in one place. Complete the first 3 confirmations before departure, and 2 activations and connection confirmations after arrival; the actual settings, installation, and usage are still based on the official information of iOS and the supplier.

Faster importing, clearer trips

Version 1.8 is available on the App Store. Core management remains free. The app includes ads and an optional one-time Remove Ads Forever purchase; it is not a subscription.

Staged pre-departure, arrival, and return checklist

Staged travel checks

Core Commitments

Choose your plan; manage to eSIMManager

No single supplier, no subscription thresholds, to help you organize dispersed travel eSIM information into a safe departure process.

Freedom to choose suppliers

Whether you get an eSIM from a travel platform, carrier, or other trusted outlet, you can organize the available activation information into an app. Offer prices, inventory, and service content will still be based on the vendor page you select.

Centralize multiple eSIMs

Keep the QR Code, LPA activation information, where applicable, expiration date, and memo in one place. Data is stored locally on your device; you can back up, share, or mark a trip as ended as needed.

Core tools stay free

There is no card-count limit. Installation guidance, pre-departure checks, expiry countdowns, and on-device usage estimates remain free. Version 1.8 includes ads and an optional one-time purchase to remove them. iPhone mobile-data and roaming settings must still be confirmed in iOS.

Primary card protection to avoid misuse of roaming data

Make sure your primary card's “Data Roaming” and “Allow Mobile Data Switching” are turned off before you leave the country, reducing the risk of high roaming charges.

  • Master Card Data Roaming: Confirm deactivation in Settings > Mobile Services > Master Card.
  • Mobile data toggle: Confirm to turn off in Settings > Mobile Services > Mobile Data.
  • Will not change automatically: The app only provides onboarding and confirmation, and the setup is still done by the user on the iPhone.

Switching Phone Backup and Restore

You can export a JSON backup and import card records on a new device; when you set a password, the backup is encrypted with AES-GCM.

  • 🔐 Optional password encryption: After setting the password, it is encrypted with AES-256-GCM; backups without a password are not encrypted, please keep it properly.
  • 📁 Flexible storage: Can be sent in the File app, iCloud Drive, or AirDrop.
  • Sensitive information exclusion: The activation code is excluded by default; such backups restore the card history but cannot be used directly for system installation.

Technical Transparency and Functional Disclaimer

In order to protect the user's right to know and to align the system with how it really works, we would like to explain the technical rationale and limitations of this app:

"Traffic is device-side estimation" Technical Instructions

The mobile traffic statistics of this app are collected through the Darwin BSD underlying getifaddrs interface, reading local pdp_ip* The cumulative number of transceiver bytes in the mobile data channel. This isDevice-side network traffic estimation reference: Unable to identify which eSIM is actually being used, traffic from other SIMs, interface resets, data waiver offers, and billing cycles can all cause discrepancies. Estimates are updated when the app returns to the outlook, not the carrier's live bill; actual remaining balance is subject to the carrier's official system.

iOS System Installation Process and Permission Regulations

Due to Apple's iOS system security, third-party apps cannot silently install eSIM directly in the background, nor can they change mobile data lines for users. Clicking “Trigger Installation” will only attempt to open Apple's system eSIM installation process; the process and ability to complete the installation will depend on the iOS version, device, network, credentials, and vendor. The user still needs to manually confirm on the system screen.

Asked Questions

Have questions about using? Take a look here

No. eSIMManager is a management and configuration facilitator that does not issue eSIM and does not restrict which vendor you buy from. As long as the supplier provides valid QR code or LPA activation information, you can organize, install, and configure according to the app and the supplier's instructions. External referral links on the website may include revenue parameters, but transactions, prices, inventory and after-sales service are provided by the supplier.
Due to Apple's iOS system security framework limitations, any third-party apps cannot install eSIM directly in the background. Clicking will only attempt to open Apple's system eSIM installation process; please confirm manually on the iOS system screen. If the process does not occur or the installation fails, please confirm iOS 17.5+, network, active activation information and provider support status, or use the QR code/official app provided by the provider.
Please ensure that the QR code or document contains valid LPA activation information (common content is LPA:1$ Beginning). Image quality, supplier format, or protected PDF may affect identification; use Manual Input instead to paste the complete LPA string provided by the supplier, or request a standard certificate from the supplier.
Normal. This function counts the throughput of the iPhone's mobile data interface, and it is not possible to identify which eSIM is actually used; the amount of other SIMs, interface resets, traffic-free offers, and different billing cycles may cause a gap. Estimates are only updated when the app returns to the outlook and are for travel reference only; the exact balance is subject to the carrier's official system.
Cards are not automatically uploaded to the cloud in this app. JSON can be exported before switching over to Configure ➔ Data Backup; passwords are encrypted. The default backup excludes the activation code, so you can restore the card history, but it may not be possible to reinstall eSIM directly; choose whether to include sensitive information and save the file properly if necessary.
