Mobile connectivity has come a long way, but even with nationwide 5G coverage, there are moments when your cellular signal isn’t strong enough—such as in steel-frame office buildings, rural areas, or while traveling abroad. Wi-Fi calling bridges that gap by letting your phone use any available Wi-Fi connection to place and receive calls. With Trump℠Mobile, Wi-Fi calling is included at no extra cost and optimized for seamless performance.
How Wi-Fi Calling Works
From a technical standpoint, Wi-Fi calling uses Voice over Wi-Fi (VoWiFi), an extension of Voice over LTE (VoLTE) technology. Here’s how it functions:
VoIP Foundation: Wi-Fi calling uses the same protocols as Voice over Internet Protocol (VoIP) services but integrates directly with your phone’s native dialer.
Seamless Authentication: When enabled, your phone authenticates over an encrypted internet connection using your SIM credentials, ensuring your identity is tied to your carrier account.
Call Routing: Instead of routing calls through the nearest cell tower, your voice data packets are tunneled through the internet to Trump℠Mobile’s network core, where they connect to the Public Switched Telephone Network (PSTN) or to other mobile networks.
Handover Technology: Many modern devices support seamless handoff between Wi-Fi and cellular networks. If your Wi-Fi signal weakens, your call can continue on 4G/5G without dropping.
Technical Benefits of Wi-Fi Calling
Improved Call Quality (HD Voice)
Wi-Fi calling supports Wideband Audio (AMR-WB codecs), which deliver clearer voice quality and reduced background noise compared to traditional narrowband calls.
Coverage Extension
Because it uses IP-based routing, Wi-Fi calling provides service in locations where cellular coverage is minimal—such as basements, rural homes, or international airports.
Encrypted Connections
All Wi-Fi calls are encrypted using IPSec tunnels, ensuring the same level of privacy and security as standard cellular calls.
Bandwidth Efficiency
Voice calls use a minimal amount of bandwidth—around 1 MB per minute—meaning even modest home or café Wi-Fi networks can support crystal-clear calls without interruptions.
Requirements for Wi-Fi Calling
To take advantage of Wi-Fi calling, you’ll need:
Compatible Device: Most modern iOS and Android devices support VoWiFi. The Trump℠Mobile T1™ Phone comes with Wi-Fi calling–ready out of the box.
Stable Wi-Fi Network: A minimum of 1 Mbps upload/download is recommended for best quality, though most home and business networks exceed this easily.
Carrier Support: Trumpâ„ Mobile includes Wi-Fi calling at no additional charge.
How to Enable Wi-Fi Calling
Enabling Wi-Fi calling is quick and built directly into your phone’s operating system:
iPhone: Settings > Phone > Wi-Fi Calling > Enable Wi-Fi Calling on This iPhone.
Android (general path): Settings > Connections > Mobile Network > Wi-Fi Calling.
Emergency Address Setup: You’ll be prompted to enter or confirm an E911 address, ensuring emergency services can locate you when calling from Wi-Fi.
Once enabled, your phone will intelligently prioritize Wi-Fi calling whenever a strong Wi-Fi signal is available, automatically falling back to cellular if needed.
