What It Is

Hiatti is a secure mobile communications app from Hiatti LLC. Its core value is giving individual users a second phone number, helping them avoid exposing their real mobile number when buying a car, making appointments, signing up for events, dating, or registering for services. It supports SMS, MMS, calls, and encrypted app-to-app messaging, and emphasizes giving users a clear boundary between trusted and untrusted contacts.

Core Capabilities and Channels

Based on the available content, Hiatti covers SMS/MMS, voice calls, and encrypted in-app messaging. It is not a traditional email platform, nor is it an enterprise SMS API platform. It offers contact management, message history, bulk inbox deletion, multi-factor authentication login, and related features. Its login security description is relatively specific, claiming that MFA avoids sending passwords over the network. In-app contacts can also be distinguished from other contacts, helping users make better communication decisions.

Coverage, Performance, and Pricing

Coverage information is limited. The terms mention being “located in the United States” and Wyoming law, but do not clearly state which countries its numbers cover, whether international SMS is supported, or whether Chinese numbers are supported. On performance, it only states that users can receive encrypted SMS “reliably and privately,” without providing delivery rates, latency, an SLA, or any availability commitment. The terms also state that uninterrupted or error-free operation is not guaranteed. Pricing is free for basic features, while premium features are available via in-app purchases or subscriptions with automatic renewal. Specific plans, monthly number fees, SMS pricing, and calling rates are not disclosed.

Compliance and Restrictions

Hiatti includes a fairly extensive set of compliance terms. Users must follow its Messaging Policy, obtain recipient consent before sending messages, and avoid illegal, fraudulent, infringing, offensive, or otherwise prohibited uses. Violations may result in numbers and accounts being suspended. It also mentions A2P messages for verification codes, security alerts, service updates, and billing notifications. Users can opt out of non-essential marketing messages, but transactional or legally required messages cannot be disabled. The content also covers authorization for CPNI management and states that phone numbers will not be sold or shared for third-party marketing.

Pros, Cons, and Who It’s For

The main advantages are its clear privacy positioning and the practical combination of a personal second number, calls, SMS, and encrypted messaging. The drawbacks are its lack of commercial transparency: there is no mention of APIs, webhooks, SDKs, or enterprise integrations, and there is no delivery-rate or coverage data. As a result, Hiatti is better suited to personal privacy protection than to business notifications, marketing blasts, or developer communications integrations.

Access from China and Alternatives

The available content does not provide information on accessibility from mainland China, app store availability, or payment support, so its China access status is unknown. If using it domestically, users should specifically verify network connectivity, number availability, in-app subscription payments, and SMS receiving scenarios. Comparable alternatives include Google Voice, Burner, Hushed, and TextNow, or local options such as secondary numbers from Chinese carriers and Ali Xiaohao.
