G100 vs Sonetel: which cheap virtual number is better in 2026?

If you're shopping for a cheap virtual number, two very different products keep coming up. Sonetel is an established international provider that has been renting virtual numbers across a long list of countries for years. G100 is a newer, narrower US-registered app built around one job: a WhatsApp-ready US or Canada number at a flat monthly price. Both can give you a second line for calls, but they solve slightly different problems.

I looked at them from the angle of a specific buyer — someone who wants an affordable number mainly for WhatsApp and calls, and doesn't want to overthink it. Here's how they actually stack up, and where each one deserves credit.

The short version

If you need a number in a particular country that isn't the US or Canada, or you want the reassurance of a provider with a long operating history and a free-plan option to test the water, Sonetel is the more flexible choice and a genuinely credible one. If your goal is a cheap, predictable, WhatsApp-ready number and you don't want to think about credit balances or country selection, G100 is the more direct fit — with one gap I'll be upfront about.

Sonetel — where it's strong

Sonetel's biggest advantage is reach. It's an established international virtual-number provider offering numbers in many countries, which is exactly what you want if your business or contacts sit somewhere specific — a local landline-style number in a European city, say, or a number that reads as domestic to customers in a particular market. That breadth is hard for a US/Canada-only service to match.

It's also been around long enough to have a track record, and it runs on a credit-and-subscription model with a free-plan option that lets you try the service before committing money. For a cautious first-timer, being able to start without a card down is a real plus, and the multi-country catalog means Sonetel can cover situations G100 simply can't reach.

Because Sonetel's pricing depends on the country and plan you choose and I can't verify exact current figures, I won't quote numbers here — but the honest summary is that it's a configurable service where your bill tracks your choices. That flexibility is the point, and it's a fair reason to pick it.

G100 — where it's strong

G100 is the newer and smaller product, and it doesn't pretend otherwise. What it does is narrow the choices down to one clear offer: a dedicated US or Canada number that's WhatsApp-ready, sold to buyers anywhere in the world with no KYC, at a flat $1.95/month. Calls, incoming SMS and WhatsApp live in a single dashboard, in the browser or the mobile app. Calls run $0.03/min, it receives SMS and OTP codes, and there's an optional official WhatsApp Business Cloud API add-on for $10/month.

The flat price is the headline. There's no credit balance to top up and watch drain — you pay $1.95 a month and add pay-as-you-go usage in USD through Stripe. For someone who just wants a US number that WhatsApp will accept, that simplicity is the whole appeal, and buyers can purchase from anywhere with no identity paperwork.

The honest gap: outbound SMS sending isn't live yet. You can receive texts and codes, make and take calls, and run WhatsApp — but you can't send a plain SMS today. For WhatsApp, OTP capture and calling that's fine; if you specifically need to text people over SMS, it's a real limitation to weigh.

The comparison that matters

Rather than line up every feature, here are the four axes that decide this for a cheap-number buyer.

Who should pick what

Pick Sonetel if the country of the number matters to you and it's not the US or Canada, or if you want an established provider with a longer history and a free way to test before you pay. Its multi-country catalog and credit-based flexibility are real strengths, and for buyers who need a specific local number it's the more capable option.

Pick G100 if you want a cheap, predictable number whose main job is WhatsApp and calls, and you'd rather not manage credits or wade through country choices. The flat $1.95/month, the WhatsApp-ready US/Canada number, the buy-from-anywhere-no-KYC access, and the single dashboard for calls, WhatsApp and incoming SMS make it the shorter path — as long as you don't need outbound SMS yet.

Neither is the wrong answer. Sonetel is the broader, more flexible international tool; G100 is the simpler, cheaper, WhatsApp-first one. Decide on two questions: does the number's country matter to you, and is WhatsApp the reason you want it? Those two point you straight at the right pick.

FAQ

Which is cheaper, G100 or Sonetel?
G100 is a flat $1.95/month, pay-as-you-go in USD via Stripe, with calls at $0.03/min. Sonetel is credit and subscription based, so what you pay depends on the country, plan and how much you call. G100 is easier to predict because the monthly figure is fixed; Sonetel can be competitive but you need to price your specific country and usage.

Is a G100 or Sonetel number ready for WhatsApp?
G100 sells a dedicated US or Canada number that is WhatsApp-ready and can receive the Meta verification code, and it offers the official WhatsApp Business Cloud API for $10/month if you need it. Sonetel is a general virtual-number provider; whether a specific Sonetel number will accept a WhatsApp registration depends on the number and country, so confirm before you rely on it.

Which is simpler for a first-time buyer?
G100 keeps it to one product: a US or Canada number at a flat price, bought from anywhere with no KYC, with calls, incoming SMS and WhatsApp in a single dashboard. Sonetel is more configurable with numbers in many countries, which is powerful but means more choices to make up front. If you just want a cheap number that works with WhatsApp, G100 is the shorter path.

Can I send SMS from G100?
Not yet. G100 receives SMS and OTP codes and handles calls and WhatsApp today, but outbound SMS sending is not live. If sending plain text messages is essential, weigh that gap against G100's flat price and its WhatsApp-ready number.
