Frequently Asked Questions

Common questions about unlisted device activation

What makes a device "unlisted" or "unsupported"?

Devices are often labeled as unsupported due to manufacturer restrictions, regional limitations, firmware versions, or simply because they haven't been officially tested. Our technology bypasses these limitations.

How do you activate eSIM on unsupported devices?

We use proprietary activation methods including IMEI-based provisioning, custom configuration profiles, and direct carrier integration that works independently of manufacturer support.

Is it safe to activate eSIM on my unlisted device?

Yes, our activation process is completely safe and doesn't modify your device's firmware or void warranties. We only configure network settings through standard protocols.

What if my device still doesn't work after activation?

Our success rate is 99%, but if activation fails, we provide full support including alternative methods, manual configuration, and if needed, a full refund of any costs.

Do you support custom ROMs and modified devices?

Yes, we support devices with custom ROMs, rooted/jailbroken devices, and modified firmware. Our activation methods are designed to work with various system configurations.
