Mobile Networks 4.0.1

For Minecraft 1.21.1 / NeoForge, requiring Simple Voice Chat.

New And Improved

• Independent four-bar reception. Signal bars now depend on distance within each technology band, rather than being fixed by the connection type. Enjoy full H+ reception or weak one-bar 5G. 5G+ and 5G share their bar range and may fluctuate at the weakest reception without adding or losing bars.
• Call mini-panel status. The translucent call preview now shows the in-world time, four reception bars, the current technology and roaming status. It stays centred on the left at a fixed size across GUI scales, and reuses existing status updates without extra server queries or network traffic.
• E+ migration. E+ is now E. Existing antenna, network, plan and roaming settings migrate automatically without deleting networks or shrinking the maximum antenna range.
• Unlimited linked Gram accounts. The old five-account cap is gone. The account dropdown loads bounded pages and supports mouse-wheel navigation forwards and backwards.
• More wheel navigation. Scroll network lists, server administration, operator plans, beneficiaries, player permissions, roaming settings, included players, carrier plans and Gallery with the mouse wheel.
• Optional vanilla text chat. Disabled by default. Singleplayer settings include an English/Spanish roleplay warning before enabling it. Dedicated servers control it through config/mobilenetworks-gameplay.toml. Server policy wins; differing local preferences do not block joining.
• Underwater reception loss. A shallow dive sharply weakens reception; a few blocks deeper mean no service even beside an antenna. Calls, data and automatic network selection all respect this restriction.

Fixes Retained From The First 4.0.1 Build

• Antennas and server blocks drop their item with stone-tier or better pickaxes. Better pickaxes mine faster.
• Persistent automatic network selection below Scan for networks, with permitted-network fallback and existing roaming/plan limits.
• Lightweight background coverage monitoring and unavailable-network notices without opening the phone.

Compatibility

• Update both the server and every client to this revised 4.0.1 build. The networking protocol changed from the first 4.0.1 build. Previous JARs are kept separately; this four-bar correction keeps protocol 13.
• Existing worlds, subscriptions, phone numbers and Gram accounts are preserved.
• English and Spanish remain supported, including automatic language selection.
• Original call sounds and textures are unchanged. Voice still uses its existing UDP port, normally 24454.
• Coverage queries remain cached, bounded and restricted to already-loaded chunks. Gram accounts are paged to avoid oversized packets.
