Zeronet Mobile: 3G, 4G, 5G

The Generations of Mobile

• 2G: The basics – calls and texts.
• 3G: Introduced mobile internet, giving smartphones their smarts.
• 4G: Faster speeds, smooth browsing, and HD streaming—even when you’re on the move.
• 5G: Super-fast downloads, lower lag, and more reliable performance, even in busy areas.

Important Update: 3G Shutdown ⚠️

• Our 3G network access will be switched off from January 2026 to focus on faster, more reliable 4G and 5G services.
• Older devices that only support 3G will no longer be able to make calls, send texts, or use mobile data after the shutdown. If you are a vulnerable caller under the 111-code, please contact your home phone service provider to ensure you are provided for in an emergency.
• To continue enjoying seamless service, ensure you have a 4G or 5G capable device. Most smartphones released since 2015 support 4G. You can check your device’s compatibility on the manufacturer’s website or contact our Care team.
• If you currently use a 3G-only device, we recommend upgrading before the shutdown to avoid service interruptions.
• We’ll send reminders closer to the shutdown date, and our Care team will help with any questions or device upgrades.
