What is a professional second number?

A professional second number is a dedicated phone number you use only for work, clients, or business — separate from your personal line. It lets you keep your private number hidden while still being reachable for calls, texts, and messaging apps. With g100.us, this second number also handles WhatsApp and SMS from the same dashboard, so you get one professional identity instead of juggling multiple contact points.

How fast can I get a professional second number with g100.us?

Numbers on g100.us activate instantly — typically live within seconds of completing signup. There's no waiting for SIM delivery, no porting delay, and no manual approval process. You choose a country and number, activate it, and you can start making calls, sending texts, or connecting WhatsApp right away through app.g100.us.

Can I get a US number even if I'm not in the US?

Yes. g100.us offers numbers in 100+ countries, including US numbers you can use from anywhere in the world — India, the UK, the UAE, Canada, and beyond. This is useful for freelancers and remote workers who need a US-facing business presence without being physically located there.

Does one g100.us number really handle calls, SMS, and WhatsApp together?

Yes. A single g100.us number covers all three channels from one dashboard: you can make and receive calls, send and receive SMS (including OTPs and verification codes), and connect the number to WhatsApp with one-click setup. There's no need for separate apps or services for each channel.

How much does a g100.us professional second number cost?

Pricing is flat and low, starting from about $4/week or $6/month, with similar pricing across most countries. You can also choose 3-, 6-, or 12-month terms for a dedicated long-term number. Everything runs on a pay-as-you-go wallet, so there are no long contracts or per-seat enterprise fees.

Can I use my g100.us number from my laptop?

Yes. g100.us offers a Chrome extension that lets you make and receive calls and texts directly from your browser while you work at your desk, with no separate phone hardware required.

g100.us supports one-click WhatsApp setup — you connect your number to WhatsApp directly from the dashboard without complex configuration. Once connected, customers and clients can reach you on WhatsApp using the same professional number you use for calls and SMS.

Do I need a contract to use g100.us?

Who should get a professional second number from g100.us?

Freelancers, consultants, remote workers, small business owners, and anyone who currently uses their personal number for work. It's especially useful if you want to keep business calls and texts separate from personal ones, need a US or international number without relocating, or want calls, SMS, and WhatsApp unified in one place.

Can I manage multiple g100.us numbers for different projects?

Yes. The app.g100.us dashboard lets you add additional numbers for different projects, clients, or businesses, each with its own calls, SMS, and WhatsApp activity, while still managing top-ups and usage from a single account.

Professional Second Number: A Step-by-Step g100.us Guide

You don't need a second phone, a new SIM card, or an enterprise phone system to separate your work life from your personal life. You need a professional second number — one that handles calls, texts, and WhatsApp from a single app, works from any device, and activates in seconds. g100.us gives you exactly that, starting at around $4/week, with no contracts and no hardware. Below is the step-by-step walkthrough for setting one up and putting it to work.

Why your personal number isn't built for professional use

Most people start freelancing, running a side business, or job-hunting using the same number they've had since college. It works for a while — until a client texts you at 11pm, a customer calls during a family dinner, or you have to give your home number to a stranger on a marketplace app. Your personal number was never designed to be a business front door.

A dedicated professional second number fixes this instantly. It creates a clean line between "you" and "your business," so you can turn work notifications off at night without missing anything important, and you can hand your number to customers, clients, or platforms without exposing the line your family and friends use.

Step-by-step: Getting your professional second number with g100.us

Step 1: Pick your country and number

Head to g100.us and choose the country your number should represent. g100.us offers numbers in 100+ countries, including US numbers you can use from anywhere in the world — so if you're based in India, the UK, the UAE, Canada, or elsewhere but need a local-looking US presence (or vice versa), you can get one without relocating or holding a local SIM.

Step 2: Sign up and activate — it's instant

Create your account, select your number, and choose a plan. There's no waiting period, no paperwork, and no installation appointment. Numbers on g100.us go live within seconds of signing up, so you can start using your professional second number the same minute you decide you need one.

Step 3: Connect the channels you actually use

This is where a g100.us number earns its keep. Instead of juggling separate apps or services for phone calls, SMS, and WhatsApp, one number on g100.us handles all three:

Calls — make and receive them from your browser or your phone.
SMS — send and receive texts, including OTPs and verification codes, instantly.
WhatsApp — connect your number to WhatsApp with one-click setup, so clients and customers can message you where they already are.

There's no need to stitch together a VOIP app, a separate texting service, and a WhatsApp Business line. It's one number, one inbox, one dashboard.

Step 4: Choose how you work — browser or mobile

At your desk, install the g100.us Chrome extension and take calls and texts right from your browser while you work. Away from your laptop, switch to the ChatLine mobile app on Android or iOS and keep the same number, same conversation history, and same contacts in your pocket. You never lose context moving between the two.

Step 5: Manage everything from one dashboard

Every call, text, and WhatsApp conversation flows into the same app.g100.us dashboard. You can top up your wallet, check usage, switch numbers, or add another line for a different project — all without calling a support line or signing a new contract.

What you actually get with a g100.us number

Strip away the marketing and here's the practical value:

One number, three channels — calls, SMS, and WhatsApp unified, so you stop giving out three different contact methods.
100+ countries — including US numbers usable from anywhere, useful for remote workers, freelancers serving US clients, and international teams.
Browser + mobile access — work from the g100.us Chrome extension at your desk or the ChatLine app when you're mobile.
Instant OTP and verification code receipt — useful for account setups, two-factor authentication, and platform verifications without touching your personal SIM.
Instant activation — live within seconds, not days.
Privacy — your personal number stays behind a professional line you fully control.

Pricing that matches how you actually work

Traditional business phone lines are usually priced for teams and departments — per-seat licenses, minimum contracts, and setup fees. g100.us flips that. Numbers start from about $4/week or $6/month, with similar flat pricing across most countries. You can also lock in a 3-, 6-, or 12-month term if you want a dedicated long-term number for a growing business.

Everything runs on a simple pay-as-you-go wallet. Top up what you need, use it across calls, SMS, and WhatsApp, and top up again when you're ready. There's no long contract holding you in, and no enterprise sales call required to get started — just g100.us and a few minutes.

How g100.us compares

If you've shopped for a business number before, you've likely run into one of these patterns with legacy providers:

Per-seat or per-user pricing that makes sense for a call center but not for a solo founder or a two-person team.
Multi-year contracts that lock you in before you even know if the number fits your workflow.
Fragmented channels — a separate VOIP app for calls, a different tool for SMS, and no native WhatsApp support, meaning you're managing three logins instead of one.
Slow provisioning — days of setup, verification, and porting before a number is usable.

g100.us was built to remove all four friction points at once: no per-seat fees, no long contracts, calls + SMS + WhatsApp in a single dashboard, and activation in seconds rather than days. For anyone who wants a professional second number without the enterprise overhead, that combination is hard to match.

Who actually needs this

A professional second number from g100.us makes the most sense if you're:

A freelancer or consultant who wants a dedicated client-facing number separate from your personal line.
A remote worker or digital nomad who needs a stable number — often a US number — regardless of which country you're currently in.
A small business owner who wants calls, texts, and WhatsApp support in one place without buying a PBX system.
Someone who regularly needs to receive OTPs or verification codes for new accounts without exposing their main number.
A job seeker or side-hustler who wants a professional contact number that doesn't ring your personal phone all day.

Making the switch

You don't need to replace your personal number to get a professional one — you just need to add a second line built for the job. With g100.us, that line is live within seconds, works across calls, SMS, and WhatsApp, follows you between your browser and your phone, and costs a fraction of what traditional business phone systems charge. Visit g100.us, pick your number, and start using it today.
