# About Shared SMS Inbox

> Shared SMS Inbox is built by Marathon Digital Pte Ltd in Singapore for teams that need a company number for login codes and account messages.

Shared SMS Inbox is built by Marathon Digital Pte Ltd in Singapore for teams that need one company number their colleagues can read together.

- [Get your number](https://app.sharedsmsinbox.com)

_No credit card required. Pay only when you choose your number._

## Built by Marathon Digital Pte Ltd

The product exists for one narrow job: stop company account messages from depending on one employee phone.

Marathon Digital Pte Ltd builds Shared SMS Inbox for teams that share access to company accounts, supplier portals, booking tools, finance software and advertising platforms.

Those services often send a text message before anyone can sign in or confirm a change. If the number belongs to one person, the whole team waits for that person. If the number belongs to the company, approved teammates can read the message themselves.

The inbox is intentionally small. It receives text messages for the accounts your company uses, shows them only to people you approve, and keeps a record of the account activity around that access.

## Plain claims, no guesswork

This website is written to be clear before somebody creates an account. The pages say what the product is for, what it is not for, what it costs, and which parts are still being confirmed.

- **Company ownership matters.** The number should stay with the team when people change roles or leave.
- **Access should be named.** Each teammate signs in as themselves, and access is granted number by number.
- **Limits should be visible.** The product is not a campaign tool, not a bulk sender, and not a customer messaging desk.
- **Open questions should stay open.** If a legal, privacy or delivery detail has not been settled, the site should say so plainly.

## Questions and support

For product questions, billing questions, or support with your account, email [support@sharedsmsinbox.com](mailto:support@sharedsmsinbox.com).

If your question is about whether a particular service will accept a number, test the number on that service before you rely on it. The service sending the message decides whether it accepts the number.

## Look around first

Create an account, inspect the product, and activate a number only when it fits the account you want to move.
