Onyx Mobile Network is recurring mobile service for data, calls, messaging, and connected communication.
Use it as your primary mobile service at home and abroad. Choose a coverage area, select a monthly data plan, add number service when you need calls and SMS, and activate the line on an eSIM-compatible device.
Onyx is not a disposable travel pass. It is mobile service built for people who move between countries, networks, devices, communication needs, and payment needs.
Plans And Coverage
Choose the coverage area that matches where you live, work, or travel.
Regional options are US & Canada, Europe, Asia Pacific, and Middle East & North Africa. Choose Global when you need service across multiple regions or regularly travel outside one regional plan.
Every mobile plan includes data. Bundled plans add number service, voice, and SMS. The app presents the current price, renewal terms, included data, number options, and service details before checkout.
Device Eligibility
Check device eligibility before checkout.
Your phone needs eSIM support, compatible network bands, roaming support when required, and unlocked status when carrier restrictions apply. Dual-SIM phones may require manual line selection after installation.
Using The Service
Use Onyx Mobile Network for browsing, messaging, remote work, hotspot, voice calls, SMS, video calls, and Onyx Chat communication based on your plan and country.
Onyx works across multiple carrier partners in supported countries so your device can stay connected while networks, regions, and signal conditions change.
When you move between regions, your device may briefly reconnect while it registers on a supported network. In some countries, registration can take up to 30 minutes because local carrier conditions and roaming behavior vary.
Coverage does not guarantee identical speeds everywhere. Performance changes between cities, buildings, transit routes, airports, and rural areas because local network infrastructure and congestion change.
Number Service
Add an Onyx number when you need calls, SMS, account recovery, or verification flows.
Number availability depends on country, local telecom regulation, voice support, SMS support, number inventory, and verification requirements.
Some countries support data only. Others support data plus voice, data plus SMS, or local numbers. Onyx shows number choices before checkout.
Activation
Onyx uses eSIM activation on supported devices.
After checkout, install the eSIM profile and activate the Onyx line on your phone. Setup may require scanning a QR code, confirming installation in cellular settings, enabling roaming, selecting the Onyx line for mobile data, or restarting the device.
Most activations complete within a few minutes. Timing can vary by device, local network registration, roaming partner, and connection quality during setup.
Managing Your Service
After activation, use Onyx to manage the mobile service.
Manage usage, renewals, number service, activation state, verification status, wallet and payment access, encrypted communication, connected apps, and permissions.
Usage updates can lag while local carriers report data use or while the device switches between roaming partners.
Device Requirements
Your device must support eSIM, compatible bands, and roaming where required.
Some devices must be unlocked before they can use Onyx service. Different phones handle eSIM installation, roaming transitions, dual-SIM settings, and line selection differently, so device behavior can vary even when the plan and region are supported.
If your phone cannot install an eSIM profile, use the device eligibility guide before buying service.
