How to Choose the Right Virtual Number for Your Use Case

A practical guide to picking the right number type, country, rental period, and platform compatibility — so you don't waste money on a number that doesn't fit.

All virtual numbers fall into three functional categories. This guide walks you through every decision you need to make before purchasing.

Number Types

SMS-only vs Voice-enabled Numbers

Understanding the three main categories will save you from buying a number that doesn't support what you need.

📞
Calls only — typically local numbers or a virtual equivalent of a landline. A good fit if you need voice communication without SMS.
💬
SMS only — exclusively mobile numbers with no VoIP telephony connected. These come in two important subtypes: local and international
📱
SMS and Calls — fully featured numbers for those who need both SMS and voice calling. Most of these are mobile numbers. In the US, Canada, and Puerto Rico, local numbers are also available — and they work the same way as mobile numbers, with full SMS and calling support.

SMS-only number subtypes

Local numbers

Work only with numbers from the same country. For example, an Italian number (+39) can only send and receive SMS to and from other Italian numbers. International messages will be blocked at the carrier level. Always check this before purchasing.

International numbers

No restrictions: send and receive SMS to and from any number in any country.

Important: it's not possible to add voice calls to an SMS-only number — this is a carrier-level limitation that cannot be bypassed.

Duration

Short-term Rentals vs Long-term Numbers

The minimum rental period is 1 month, the maximum is 1 year. Once the year is up, you can keep using the number by renewing it monthly through the auto-renewal feature.

Why we recommend long-term rental

🔒
Reliability — the number is yours for an extended period, and you won't risk losing access to it.
⏱️
Convenience — no need to track expiration dates or remember to renew.
💰
Savings — discounts of 10 to 20% depending on the rental period you choose.

Short-term rental only makes sense in one scenario: you need to receive a one-time SMS or call and have no further use for the number after that.

Compatibility

Choosing Numbers by Country and Platform

By country

The majority of our numbers are international, meaning they work the same way across all countries and platforms with no restrictions. That said, it's worth thinking through your use case before purchasing.

For international services — WhatsApp, Telegram, Instagram, etc.

Affordable mobile numbers from the UK, Poland, Australia, and similar countries will work just fine.

For local services — Country-specific platforms

Some platforms only accept numbers from a specific country. For example, certain Swiss classifieds sites will reject any foreign number. In these cases, you need a local number — check availability on our platform before buying.

For outbound calls to customers — Building trust with local presence

A local number builds more trust. People are far more likely to pick up when they recognize the country or area code.

By platform

Most services accept any number, but there are a few things to watch out for.

Major platforms — WhatsApp, Telegram, PayPal, Google, and similar — deal with large volumes of fraud and fake account creation. As a result, they have sophisticated systems for detecting virtual numbers, and only a limited set of numbers will work with them.

You can find an up-to-date list of supported platforms at our Platforms page. It covers several dozen of the most popular services and is updated regularly. If a service you need isn't listed, just reach out to our support team — they'll check it for you.

Tip: a single number can be used across multiple platforms. If the list shows that a Finnish number works with both Wise and Revolut, you only need to buy one number to use it for both.

Use Cases

Business vs Personal Use

Any number available on our site can be used for personal or business purposes — whether that's a corporate phone line or a work account on a third-party service.

Beyond the numbers listed in our main catalog, we also work with a range of countries not publicly available on the site: Germany, Austria, Belgium, France, and others. These numbers are available exclusively for business clients and require supporting documentation — proof of company registration and other paperwork (contact support for the full list of requirements).

Business clients can also request a test number before committing to a purchase — a good way to verify compatibility with your target platform or service.

Before You Buy

Checklist Before Purchasing a Virtual Number

Before placing your order, run through these points — it takes just a few minutes and can save you from unnecessary costs and frustration.

✓Decide on the functionality you need — SMS, calls, or both?
✓Check the number type — if you only need SMS, make sure the number is international rather than local (especially if you'll be messaging contacts in other countries).
✓Verify platform compatibility — particularly if you plan to use WhatsApp, Telegram, PayPal, Google, or other major services.
✓Choose the right country — do you need a local number for a specific service or region, or will any international number do?
✓Decide on the rental period — if you need the number long-term, locking in a multi-month plan with a discount is the smarter move.
✓If you're a business client — check whether your target country is available in our extended catalog, and request a test number before purchasing.
