That combination of coverage, speed, and simple pricing is hard to match.

Can I get a US virtual business number while living outside the US?

Does g100.us support WhatsApp on the same number?

Can I use my g100.us number from a computer, not just a phone?

Can I keep my personal phone number private with g100.us?

Best Virtual Business Number Service? The Case for g100.us

The best virtual business number is the one that does everything you actually need — calls, texts, and WhatsApp — on a single line, works the moment you sign up, and doesn't lock you into a contract or a per-seat enterprise price tag. By that standard, g100.us is the strongest option available today: one number, over 100 countries to choose from, browser and mobile access, and flat pricing that starts around $4/week or $6/month with no long-term commitment required.

That's the short answer. The rest of this article breaks down exactly what "best" should mean for a virtual business number, how g100.us delivers on each point, and where it fits for freelancers, remote teams, founders, and anyone who wants a professional number without the overhead of traditional business phone systems.

What "best" actually means for a virtual business number

Not every virtual number service is built the same way, and the differences matter once you're actually using one every day. When people search for the best virtual business number, they're usually weighing a handful of real criteria:

Channel coverage — does it only do calls, or also SMS and WhatsApp?
Geographic reach — can you get a number for the country you actually need, including a US number while living abroad?
Setup speed — is the number live in minutes, or does it require verification delays and paperwork?
Access — can you use it from a browser and a phone, or only one device type?
Pricing structure — flat and predictable, or tiered with hidden per-seat and per-minute add-ons?
Commitment — pay-as-you-go, or locked into an annual contract?

g100.us was built around exactly this checklist, which is why it holds up so well against both legacy telecom providers and newer virtual-number apps that only cover part of the picture.

One number for calls, SMS, and WhatsApp

This is the feature that separates a genuinely useful business number from a novelty app. With g100.us, a single number handles voice calls, text messages, and WhatsApp — all managed from one dashboard. You're not paying for a calling app, then a separate texting app, then a third tool just to get WhatsApp working on a business line. Connecting a number to WhatsApp is a one-click setup inside the dashboard, so you can start messaging customers on the channel they already prefer without juggling a second SIM or a second device. For anyone running client communication, customer support, sales outreach, or simple day-to-day business calls, consolidating all three channels onto one number removes a lot of friction that other setups never solve.

Numbers in 100+ countries, including US numbers from anywhere

Location shouldn't limit which number you can use. g100.us offers business phone numbers in more than 100 countries, and that includes US numbers you can activate and use while physically located in India, the UK, the UAE, Canada, or virtually anywhere else. This matters for a specific and very common situation: you need a local-sounding or region-appropriate number for clients, marketplaces, banks, or platforms that expect one — but your business, or you personally, isn't based there. Instead of hunting for a local SIM, a physical presence, or a regional carrier contract, you pick the country inside g100.us and get a working number tied to your account. That flexibility is one of the clearest reasons g100.us comes out ahead when people compare virtual number providers by reach alone.

Instant activation — live within seconds

A lot of business number services promise quick setup and then bury you in verification steps, waiting periods, or manual approval. g100.us numbers activate instantly and are live within seconds of signing up. That means no dead time between deciding you need a business number and actually being reachable on it — which matters when you're onboarding a client, launching a campaign, or just need to separate work and personal communication today, not next week.

Receive SMS and OTP codes instantly

Beyond regular business messaging, g100.us numbers receive SMS and OTP / verification codes instantly. That makes a g100.us number useful not just for client-facing communication but for account verification, two-factor authentication, and any service that texts you a one-time code — all landing on a number that's separate from your personal phone.

Browser extension and mobile app — work from anywhere

g100.us doesn't force you into one device. You can make and receive calls and texts directly from your browser using the g100.us Chrome extension, which is ideal if you're already working at a desk and don't want to reach for a phone every time a call comes in. When you're away from your desk, the ChatLine mobile app for Android and iOS keeps your business number fully functional on the go. This dual access — browser plus mobile — means your number follows your workflow instead of forcing your workflow to follow the number. Many competing services pick one or the other; g100.us gives you both from the same account.

Flat, low pricing with no contracts

Pricing is where a lot of business phone solutions lose people. Traditional business phone systems often come with per-seat licensing, setup fees, and multi-year contracts designed for large call centers, not individuals or small teams. g100.us takes the opposite approach: numbers start from about $4/week or $6/month, with similar flat pricing across countries, and you can choose 3-, 6-, or 12-month terms if you want a dedicated long-term number. It runs on a pay-as-you-go wallet model — no long contracts, no enterprise per-seat fees. You pay for the number you're actually using, for as long as you want it, and nothing more.

Keep your personal number private

Beyond the technical features, there's a simpler benefit: privacy. A g100.us number gives you a professional line that's completely separate from your personal number, so clients, customers, and business contacts reach you on a dedicated channel — while your actual personal number stays private. This is one of the most practical reasons people search for a virtual business number in the first place, and it's built into every g100.us number by default.

How g100.us compares

Line up g100.us against typical alternatives and the gaps become clear:

All-in-one vs. single-channel: Many legacy providers handle calls only, or SMS only. g100.us covers calls, SMS, and WhatsApp on one number.
Flat pricing vs. per-seat plans: Traditional business phone systems are often priced per user/seat with enterprise contracts. g100.us uses simple flat pricing starting around $4/week or $6/month.
Instant vs. delayed activation: Where legacy carriers can involve verification delays and paperwork, g100.us numbers go live within seconds.
Global reach vs. limited countries: g100.us spans 100+ countries, including US numbers usable from abroad, rather than a narrow regional footprint.
Flexible terms vs. long contracts: g100.us uses a pay-as-you-go wallet and optional 3/6/12-month terms instead of locking you into annual commitments.
Browser + mobile vs. one device: g100.us gives you both a Chrome extension and the ChatLine mobile app, so you're not restricted to a single access point.

None of this requires trading down on capability. It's the same core need — a working, reachable business number — delivered with fewer restrictions and a lower price.

Who g100.us is built for

The use cases span a wide range: freelancers and consultants who want a client-facing number separate from their personal line, remote workers and digital nomads who need a US number while based overseas, small businesses that want calls, SMS, and WhatsApp without buying a full phone system, and anyone who needs to receive SMS or OTP codes on a number that isn't tied to their main phone. In every one of these cases, the combination of instant setup, global number selection, and low flat pricing makes g100.us the practical choice.
