How it works

Go to https://microesim.com and select your travel destination or region.

Browse the available plans based on your destination country, trip duration, and data needs (500MB, 1GB, 5GB, 10GB, unlimited, etc.).

Select your preferred payment method (Visa, Mastercard, PayPal, Apple Pay, Google Pay, or Alipay) and complete the transaction securely.

Within 12 seconds of your purchase, you will receive an email containing your QR code and installation instructions.

On your eSIM-compatible phone, go to Settings > Mobile Data > Add Mobile Plan, then scan the QR code received by email.

Follow the confirmation steps and assign a name to your MicroEsim eSIM profile for easy management (e.g., 'MicroEsim France').

Upon arrival in the target country, go to Settings, select MicroEsim as the default operator for mobile data, and enable roaming if necessary.

⚠️ If it fails

✅ Check that your phone is eSIM compatible. Ensure a good Wi-Fi connection during installation. If the QR code appears invalid, contact MicroEsim immediately by email at [email protected] for a resend or refund.

✅ Toggle airplane mode off and on, verify that MicroEsim is selected for mobile data and that international roaming is enabled. Restart your phone. If the issue persists, contact MicroEsim support.

✅ Move away from crowded areas, check that you have credit/data available, and try switching 4G/5G networks. Some countries have better coverage than others; contact support to confirm local coverage.

✅ Check your data balance via the MicroEsim website. If you have an unlimited plan with a speed limit after a certain volume, this is expected behavior. Purchase an additional plan if necessary.
