Engineered for 4G LTE VoLTE connectivity, rugged durability, and localized Spanish firmware customization.
Navigating network migration, urban safety demands, and compliance requirements in Mexico's high-growth telecommunication ecosystem.
Full hardware integration supporting Telcel and AT&T Mexico 4G LTE Bands B2 (1900 MHz), B4 (AWS), B5 (850 MHz), and B28 (700 MHz Red Compartida) for seamless voice coverage across Greater Mexico City.
We provide full technical dossier preparation, schematics, and sample calibration required for smooth approval by the Instituto Federal de Telecomunicaciones (IFT) and NOM certification bodies.
Complete white-label capability including pre-installed Spanish language packs, custom boot screens, custom packaging, and localized iOS/Android parental control apps hosted on AWS Americas nodes.
Mexico City's ambient background noise level—ranging from busy Metro stations to heavy traffic on Paseo de la Reforma—demands specialized acoustic hardware.
Our OEM audio calling smartwatches integrate Dual-Microphone Environmental Noise Cancellation (ENC). Primary mic captures voice; secondary mic samples background noise, applying digital signal processor (DSP) subtraction for crisp HD VoLTE voice transmission.
Acoustic Echo Cancellation (AEC) prevents feedback loops during hands-free speakerphone mode. Dynamic Gain Control automatically adjusts speaker output volume based on surrounding noise levels up to 88 dB SPL.
Powered by UNISOC W307/8521E and ASR3603 LTE platforms. Optimized RTOS operating systems ensure minimal power draw during active 4G calling sessions, extending daily battery life under heavy operational use.

Deploying wearable technology engineered for real-life urban, safety, and commercial requirements in Central Mexico.
Navigating crowded areas such as Polanco, Coyoacán, or municipal transport hubs requires reliable real-time tracking. Parents in CDMX set customized safe zones (Geofences) via our app. If a child leaves designated boundaries, instant SOS voice alerts and push notifications are triggered to guardian smartphones over Telcel's 4G network.
Mexico's aging demographic relies on wearable health trackers equipped with one-touch emergency voice calling, automatic fall detection, PPG heart rate monitoring, and blood oxygen (SpO2) alerts. Data automatically syncs with private clinics or family care networks without needing complex smartphone setups.
Logistics operators across Naucalpan, Santa Fe, and Vallejo utilize rugged 4G calling watches for motorcycle couriers and warehouse personnel. Push-to-Talk voice calls, hands-free operation, and continuous AGPS location tracking streamline urban distribution while enhancing worker safety.
State-of-the-art production lines, rigorous quality assurance, and end-to-end supply chain transparency.
Clear, authoritative answers addressing technical specifications, order logistics, compliance, and white-label options.
Yes. Our audio calling smartwatches are custom-engineered with multi-band RF front-end modules supporting 4G LTE Bands B2 (1900 MHz), B4 (AWS 1700/2100 MHz), B5 (850 MHz), and B28 (700 MHz). This guarantees seamless VoLTE voice calling and fast data transmission across Telcel, AT&T Mexico, Movistar, and Red Compartida MVNO networks.
We provide comprehensive engineering support for importers pursuing IFT (Instituto Federal de Telecomunicaciones) homologation and NOM-001-SCFI / NOM-208-SCFI certifications. We supply complete RF test reports, circuit schematics, PCB layouts, block diagrams, and golden samples ready for local lab testing in Mexico City.
Our standard Minimum Order Quantity (MOQ) for custom logo printing, packaging, and Spanish firmware pre-installation starts at 500 to 1,000 units per model. For full ODM projects requiring custom structural molds or bespoke PCB engineering, MOQ depends on project scope. Stock units with standard packaging can be ordered starting at 100 units.
Absolutely. We offer complete white-label app customization for both iOS App Store and Google Play Store. We customize the app name, icon, brand color scheme, splash screen, and user interface elements in Spanish. Additionally, backend server APIs can be integrated into your company's localized cloud infrastructure.
We offer flexible shipping terms including FOB Shenzhen/Hong Kong, CIF Manzanillo/Veracruz, or DDP (Delivered Duty Paid) air freight directly to your warehouse in Mexico City. Our logistics team handles export customs clearance, MSDS battery documentation, and UN38.3 transport certifications.
We provide a comprehensive 12-month factory warranty covering manufacturing defects and hardware performance. For bulk orders, we offer 0.5% to 1% spare units or spare parts (screens, batteries, straps, motherboards) free of charge to facilitate rapid local RMA resolution in your service centers.
We offer both standalone 4G LTE cellular smartwatches (equipped with Nano-SIM or eSIM slots) that operate completely independently of a phone, as well as Bluetooth 5.2 calling watches that pair with smartphones. Standalone models allow children or elderly users to call, message, and transmit GPS coordinates without carrying a separate mobile phone.
Parents can set scheduled quiet hours ("Classroom Mode") via the companion application. During active school hours, touchscreen interactions, games, and non-essential calls are locked, while background GPS tracking and emergency SOS button functionality remain fully active for child safety.
