YOUR MOBILE · YOUR NUMBER · YOUR CHOICE OF AI

Let your mobile answer SMS with AI.Choose ChatGPT or Claude.

A customer texts your real mobile number. SMSMobileAPI passes the eligible message and its conversation context to the AI mode you selected for that phone. Review the proposed reply or let your connected Android mobile send it automatically through its own SIM.

A PRACTICAL ASSISTANT FOR REAL SMS

Respond sooner, keep your number and stay in control.

Use AI for the repeatable part of an SMS conversation while your connected Android phone remains the sending and receiving endpoint.

01

Be present when you are busy

Answer common questions, collect missing details and acknowledge requests without leaving every sender waiting.

02

Keep conversations consistent

Give each mobile its own role, tone, hours, excluded contacts and signature. The right context follows each conversation.

03

Move at your own pace

Start with human approval. Review real drafts and only enable automatic sending when your instructions work as intended.

ONE MOBILE PLATFORM. TWO AI PROVIDERS.

Choose the AI you want behind your SMS replies.

The same mobile controls, approval queue and conversation history are available with either provider. Choose one for each reply mode, then assign that mode to a phone.

OpenAI models

ChatGPT

Connect ChatGPT to your mobile SMS.

Use the managed SMSMobileAPI AI connection or configure your own OpenAI API key. Choose a supported model, define the reply mode and decide how every draft is handled.

Anthropic models

Claude

Connect Claude to your mobile SMS.

Add your own Anthropic API key privately in the dashboard, choose a supported Claude model and give it the same per-mobile rules and human approval options.

Your own Anthropic API key is required
Discover Claude replies

Both providers use your connected Android mobile for SMS. Claude currently needs your own Anthropic API key; a managed Claude connection is not available.

FROM THE FIRST SMS TO THE NEXT USEFUL ANSWER

Four steps to connect AI to your real mobile.

  1. 01

    Connect your Android mobile

    Install SMSMobileAPI and explicitly enable received-SMS synchronization in the app. Keep the phone connected for incoming messages and outgoing replies.

  2. 02

    Choose the AI provider

    Select ChatGPT or Claude, choose a supported model and configure the provider connection that applies to your choice.

  3. 03

    Create a reply mode

    Describe what the assistant may say, its tone, working hours, signature, excluded numbers and when a human must take over.

  4. 04

    Assign, test and activate

    Assign the mode to a connected phone. Start with approval, test a full SMS exchange and then decide whether automatic sending is appropriate.

AUTOMATION THAT FOLLOWS YOUR RULES

Every reply mode has its own limits and history.

The account owner decides when AI may answer, which numbers are excluded and whether a person must approve a draft.

One mode per mobile

A sales mobile and a support mobile can follow different instructions from the same account.

Separate conversation memory

Context stays tied to the correspondent’s number, receiving mobile and assigned mode.

Human approval

Approve, archive or refuse a proposed reply before it reaches the customer.

Schedule and exclusions

Choose active days and hours, exclude named numbers and avoid replies to short numbers.

Sending and cost history

See generated drafts, decisions, sending status and the customer-visible amount charged.

START SIMPLE. EXPAND WHEN YOU ARE READY.

Useful replies for the conversations you already receive.

01

After-hours enquiries

A customer asks when you are open. The mobile answers with the hours in your instructions or prepares a draft for review.

02

Lead qualification

A new prospect gets a first reply and the next useful question while a salesperson is unavailable.

03

Bookings

Collect a preferred date and missing details while leaving final confirmation to a person when needed.

04

Customer support

Answer familiar questions and hand uncertain or sensitive situations to your team.

CLEAR COSTS

See the charge for every generated reply.

The base SMSMobileAPI platform charge is $0.005 per generated reply. Your AI provider may bill model usage separately when you use your own key. SMS sent by your mobile remain subject to your operator’s plan.

PRACTICAL QUESTIONS

Know what happens before the first automatic reply.

Begin with human approval and a test contact. Your Android phone must remain connected, with received-SMS synchronization enabled in the mobile app.

Does the SMS come from my own number?

Yes. Approved or automatic replies are queued to the connected Android phone and sent through its SIM and mobile number.

Can I use a different AI provider for each mobile?

Yes. Create separate reply modes and assign the appropriate ChatGPT or Claude mode to each connected mobile.

Can I approve every answer before it is sent?

Yes. Choose human approval for a mode and approve, archive or refuse each generated draft in the dashboard.

Do I need an API key?

Claude currently requires your own valid Anthropic API key. For ChatGPT, you can use the managed SMSMobileAPI connection or configure your own OpenAI API key.

How are AI replies billed?

The base SMSMobileAPI platform charge is $0.005 per generated reply. Provider usage may be billed separately when you use your own key. Your mobile operator may charge for sent SMS under your plan.

Will AI always answer correctly?

No. AI can misunderstand or produce an unsuitable answer. Start with human approval, give precise instructions and keep a person responsible for important decisions.

YOUR NUMBER. YOUR RULES. YOUR AI PROVIDER.

Give your mobile a useful way to answer.

Choose ChatGPT or Claude, set the instructions and begin with a controlled SMS exchange.
