Direct eSIM Installation

No QR Codes. No Manual Configurations.

Many travel eSIM apps send you an email with a QR code that you have to scan from another device, or copy-paste long SM-DP+ codes into your phone settings. Unisimcard integrates directly with your iOS or Android device settings. Once you purchase your plan, just tap **Install eSIM** inside the app, and the eSIM will automatically mount on your device in seconds.

Integrated Calling Dialer

Stay Reachable Worldwide.

Most travel eSIMs are data-only, meaning you lose the ability to place phone calls or receive SMS authentication codes. Unisimcard provides a dual data-and-voice capability. Using the app's integrated dialer, you can make VoIP calls to landlines or mobile numbers anywhere in the world, and receive incoming verification SMS directly on your Unisimcard number.

Frequently Asked Questions

Do I need to scan a QR code to install the eSIM?

No! Unlike other eSIM providers, the Unisimcard app supports automatic 1-click direct installation. Once you buy a plan or activate a line, simply tap the installation button inside our mobile app, and the eSIM will configure itself directly in your phone settings.

Does my phone need to be unlocked?

Yes. To use any travel eSIM, your device must be carrier-unlocked. If your phone is locked to a specific carrier (e.g. AT&T, T-Mobile, Verizon), you must contact them to unlock your device before installing a travel eSIM.

Can I make phone calls with Unisimcard?

Yes, absolutely! While most travel eSIM apps are data-only, Unisimcard has a built-in VoIP dialer on the app home screen. You can make international calls and receive SMS/OTP verification codes directly through your wallet credit balance.

Does my wallet balance expire?

No. Your Unisimcard cash wallet balance has no expiration date. If you do not use all of your loaded credit on a trip, it remains safely in your wallet and is ready to be used on your next travel adventure.
