AI Phone

What is AI Phone?

AI Phone is a mobile app that translates live phone, voice and video calls, so two people without a shared language can hold a normal conversation. You speak in your own language, the other caller hears your words in theirs, and both sides see bilingual subtitles.

The app works as a go-between on the call. It listens to each speaker, converts the speech to text, translates it and plays the result as synthetic speech, which adds a short pause between turns. The other person does not need the app, because AI Phone sends them an invitation link that opens the translated call. Beyond calls, the app also covers face-to-face conversations, camera translation of printed text, live audio stream translation and short AI summaries after a call.

Second Phone Number Inc publishes AI Phone on the App Store and Google Play. It launched in 2024 as a second US number with English transcription, which is how several directories still describe it, and later shifted its focus to speech-to-speech translation. The iPhone listing shows a 4.7 rating from about 82,000 reviews and a September 2026 update that improved accent handling and video call voice capture.

Key Features

Two-way call translation and link-based invitations let you phone someone abroad through AI Phone without asking them to install anything.

• Live call translation: AI Phone translates both sides of a phone call in close to real time, across more than 150 languages and accents. Each turn is spoken back in the listener’s language, and a transcript builds up on screen as the conversation goes on.
• Video and app calls: The app adds translation to voice and video calls on WhatsApp, WeChat, Telegram and, according to its App Store listing, more than 20 apps in total. This means you can keep using whichever messenger your contact already prefers.
• Bilingual subtitles: Each spoken line appears in both the original language and the translation. Reading the two versions side by side helps you spot a mistranslated name, date or price before the call moves on.
• Conversation mode: A split-screen mode translates in-person chats on a single phone placed between two speakers. It suits a pharmacy counter, a taxi or a hotel desk where there is no call to join.
• Camera and document translation: The camera tool translates text in photos of signs, menus, letters and forms. The latest version notes describe wider document and photo recognition, which helps with official paperwork in an unfamiliar language.
• Summaries and AI number: After a call, the app can produce an AI summary and file it in a searchable call history. Paid subscriptions are still branded as AI Phone Number plans, so they include a virtual number alongside translation.

Pros

Only you need the app, so a single AI Phone install covers calls with landlords, clinics and suppliers in many countries.

• Wide language coverage: AI Phone lists more than 150 languages and accents, well beyond many phone-based translators. Speakers of less common languages are therefore more likely to find their pair supported.
• Nothing for the other side to install: The invited caller simply opens a link and talks. This matters most for older relatives, busy offices and one-off calls where asking someone to download an app is unrealistic.
• Strong user ratings: The iPhone app averages 4.7 out of 5 from roughly 82,000 ratings. Review analysis by Kimola also records a Net Promoter Score of 70, which points to broadly satisfied regular users.
• Several tools in one app: Call, voice, conversation, camera and audio stream translation sit in the same app and share one subscription. Travellers can therefore drop two or three single-purpose translators from their phone.
• Frequent updates: The developer ships regular releases, with version 3.43.3 in September 2026 improving accent accuracy and video call voice capture. Active development suggests problems reported in reviews do get attention.

Cons

Frequent callers pay heavily for AI Phone, since the weekly plan alone works out at well over $400 a year.

• Translation lag: Every turn needs a short pause while speech is recognised, translated and played back. Quick back-and-forth exchanges can feel stilted, so short sentences and patient turn-taking work best.
• Subscription cost: Weekly, monthly and annual plans plus credit packs can add up quickly. The annual plan at $59.99 is far cheaper per week, so occasional users should avoid the weekly option.
• Data collection: The App Store privacy label lists audio, messages, contact details and device identifiers as data linked to you. It also states that identifiers may be used for tracking, which matters for sensitive calls.
• Virtual number limits: Reviews summarised by Kimola report that the AI number cannot receive SMS verification codes or take calls forwarded from a physical number. Do not plan to use it as a full replacement line.
• Billing and support complaints: Some users report unexpected charges after the trial and slow replies from support. Cancelling through your App Store or Google Play subscriptions page before the trial ends avoids most of these problems.

Who is Using AI Phone?

AI Phone is mainly used by people who must phone someone in a language they do not speak well, from immigrants to small exporters.

• Immigrants and expatriates: Newcomers use it for calls with landlords, schools, banks and doctors’ surgeries. The link invitation helps when the office on the other end will not install anything.
• Travellers: Tourists book hotels, taxis and restaurants abroad and use conversation mode at reception desks. The camera tool covers menus, timetables and street signs.
• Small business staff: Buyers and sales staff talk to overseas suppliers and clients without hiring an interpreter. Bilingual subtitles let them check prices, quantities and delivery dates as they are said.
• Multilingual families: Families keep in touch with grandparents and relatives who speak a different language. Video call translation on WhatsApp or WeChat keeps those calls on the apps they already use.

Pricing

AI Phone is free to try, then US App Store plans cost $8.99 a week to $59.99 a year (App Store listing, checked October 2026).

An app design teardown reports that the trial lasts three days and is attached to the weekly plan, while one directory still quotes $9.99 a month from the older version.

Store prices vary by country and can change between app versions, so check the figure shown in your own store before you subscribe.

What Makes AI Phone Unique?

Two-way speech translation inside the call apps people already use is the key difference. Most rivals, such as built-in phone translators or conversation apps, need both people on the same device brand or the same app, while AI Phone sends a link so the other caller can stay on WhatsApp or a normal line.

The breadth of the toolkit adds to that. Few call translators also include camera translation, audio stream translation and post-call summaries, so AI Phone works as a general travel and relocation translator rather than a single-purpose calling tool.

Compatibilities and Integrations

AI Phone runs only on iPhone and Android phones, and it connects to regular calls plus the main messaging apps.

• Platforms: iOS 15.5 or later and Android; the iPhone download is about 225 MB.
• Call apps: Phone calls, WhatsApp, WeChat, Telegram and, per the App Store listing, more than 20 apps in total.
• Languages: More than 150 languages and accents for translation; the app interface is offered in 16 languages.
• Web access: No web or desktop version, so calls must start from the phone.

AI Phone Tutorials

A first translated call takes about five minutes to set up from a fresh install.

1. Install the app, create an account and allow microphone access.
2. Choose your language and the other caller’s language.
3. Start a phone call, or send the invitation link through WhatsApp, WeChat or Telegram.
4. Speak in short sentences and check the bilingual subtitles after each turn.
5. Open the call history afterwards to read the AI summary.
6. Pick a plan, or cancel in your store settings, before the trial ends.

How We Rated It

AI Phone scores 3.7 out of 5 overall, earning high marks for ease of use and features but losing ground on privacy, support and translation lag.

Summary

AI Phone suits immigrants, travellers and small firms that need to phone across a language gap without asking the other side to install anything. Its call, conversation and camera tools cover most everyday situations abroad in one app. Cost is the main drawback for frequent callers, and the privacy label is worth reading before sensitive calls. The virtual number is not a full replacement line either. Try it on a real call during the trial, then choose the annual plan if you will keep using it.
