Fonable

Fonable is a browser-based international calling service that helps users call real landline and mobile phone numbers abroad without a SIM card, native app, or monthly phone-system subscription. Fonable is designed for individuals, professionals, and small teams that need outbound international calling from a web browser. Users sign in, add pay-as-you-go credits, enter an international number, and place calls over their internet connection. The product focuses on calling real phone numbers rather than app-to-app voice or video calls. Fonable is used by travelers, expats, immigration professionals, recruiters, consultants, real estate agents, travel agents, agencies, and globally active small businesses. Common use cases include calling airlines, banks, embassies, government offices, hotels, customer support lines, international clients, overseas candidates, and service providers that require a phone call. Main features include: - Browser-based calling: users can place calls from a supported web browser without installing a desktop or mobile calling app. - International outbound calls: Fonable supports calls to landlines and mobile numbers in 180+ countries. - Pay-as-you-go pricing: users add credits and pay by the minute instead of buying a monthly calling plan. - No SIM requirement: calls are placed through the browser session and internet connection, not a mobile carrier SIM. - Simple account setup: users sign in, add credits, and dial supported international numbers from the web dialer. Fonable is not a full contact center or enterprise PBX. It is better suited for users who mainly need straightforward outbound international calling without extensions, desk phones, long-term contracts, or complex phone-system setup. For occasional international calls, customer-service calls, and cross-border professional communication, Fonable provides a focused web softphone for calling real phone numbers from the browser.

GigTel

GigTel is a cloud communications provider delivering Unified Communications as a Service (UCaaS) and Contact Center as a Service (CCaaS) solutions built for small and mid-sized businesses. Backed by parent company Endeavor Communications' 70+ years of telecommunications experience, GigTel combines enterprise-grade reliability with the simplicity, affordability, and hands-on support that growing businesses need from a business phone system provider. At the core of GigTel's platform is cloud-hosted VoIP (Voice over Internet Protocol), giving businesses a modern alternative to legacy on-premises PBX systems. Rather than juggling separate tools for calling, video conferencing, messaging, and faxing, GigTel unifies these capabilities into a single cloud-based communications platform — reducing cost, complexity, and IT overhead. Core features include a multi-tiered Auto Attendant virtual receptionist with unlimited call routing, HD video conferencing and screen sharing for up to 25 participants, advanced voicemail with speech-to-text transcription, and a full-featured mobile app for iOS and Android that lets employees call, message, and manage settings from anywhere. GigTel's Inclusive License Model bundles most features standard rather than charging for add-ons, and businesses can choose between Standard and Advanced seats — mixing and matching across their organization as needs change. For businesses looking to modernize existing infrastructure without a full platform migration, GigTel also offers affordable SIP Trunking. Compliance is a key differentiator: GigTel's UCaaS and CCaaS platform has been third-party audited for HIPAA compliance, and GigTel will sign a Business Associate Agreement (BAA) — making it a strong fit for healthcare practices, dental and mental health providers, legal offices, and any business that discusses sensitive information by phone. Number porting is handled in-house, typically completed in 2–4 weeks, and every customer is backed by unlimited 24/7 U.S.-based support. Beyond direct customers, GigTel partners with Managed Service Providers (MSPs), telecom resellers, and technology brokers through its Channel Partner Program, and with voice and broadband providers through its White Label Program — allowing partners to offer GigTel's UCaaS and CCaaS platform under their own brand. An additional Referral Partner Program lets individuals earn ongoing residual income by connecting businesses with GigTel, with no telecom background required. Whether you're a growing business replacing an outdated phone system, a healthcare organization needing HIPAA-compliant communications, or a service provider looking to white-label a reliable cloud communications platform, GigTel delivers the flexibility, compliance support, and dedicated service to scale with you.
