Create free accountHow it works

Conceptual interface. Not a live service screenshot.

Your HarmanCell account

Browse numbers, manage your lines and keep their histories separate. Communication features depend on the number and account.

By feature

Multiple numbers

Hold more than one additional number in a single customer account, so work and life stay on different lines.

By feature

Separate histories

Each number keeps its own conversation and call history.

Communication and account controls

By feature

Calls

Receive calls on numbers that support calling. Placing a call is an extra feature, opened only where that number allows it.

By feature

Messages

Receive SMS and verification messages where supported. Sending a message is an extra feature, opened only where that number allows it.

Account security

Secure account

Verified sign-in, session inventory and device revocation already exist in the product foundation.

Later work

Business-ready foundation

Individual and business account types exist. Shared team administration is later work.

Getting started

How it works

Create an account, confirm your email and browse current offers in the Number Store.

  1. Getting started · 1

    Create your HarmanCell account

    You will sign in with an email address you control. The account is yours, not anonymous.

  2. Getting started · 2

    Choose an available number

    Search the Number Store for current UK mobile offers. Some countries and number types will need identity or address evidence first.

  3. Getting started · 3

    Receive SMS and calls where supported

    You receive SMS and calls on numbers that support them. Sending a message or placing a call opens later, and only where that number allows it.

  4. Getting started · 4

    Manage communication from HarmanCell

    Keep work and personal conversations on the number they belong to. Review renewal details and number-release controls in your account. A number is a service, not property you own.

Read the full path

Personal and work, on different numbers

Manage additional personal and work numbers in the same account.

Personal

A number for everyday life that does not have to be the mobile in your pocket.

Work

A dedicated line for clients and colleagues, without buying a second handset.

Account security

These are verified account controls, not certificates, partner logos or customer counts.

Verified customer accounts

Access starts with an account the customer can prove they control. It is not a walk-up anonymous kiosk.

Connection secrets stay server-side

Connection credentials never ship to apps or browsers. Customers manage numbers in HarmanCell.

Auditability

Security-sensitive account actions are recorded so a later review can see what happened, not guess.
