How to Have a Second WhatsApp Account (Without a Second SIM)

Three ways to run two WhatsApp accounts on one phone. One is free and easy but limited. One is newer and buggy. One works fully but costs a couple of euros. Here's when to use each.

Why people want two accounts

The reasons I hear most often, in order:

• Business + personal. Freelancers, small shop owners, real-estate agents — anyone whose customers found their personal number and won't stop messaging at 11pm.
• Marketplace listing. Selling on Vinted, Facebook Marketplace, or OLX and not wanting strangers to have your real WhatsApp for the next five years.
• Two SIMs, one phone. People with a work SIM and a personal SIM who want to use both on WhatsApp simultaneously.
• Privacy separation. A public identity for online friends and a private one for family.

Each reason maps to a different method. Below are the three that actually work in 2026.

Method 1: WhatsApp Business app (dual-app method)

WhatsApp lets you install two separate apps on the same phone: the regular WhatsApp and WhatsApp Business. Both work independently, each has its own account, each tied to a different phone number. This is the built-in supported way — no hacks, no risk of a ban.

Steps:

1. Keep your existing WhatsApp installed with your main number.
2. Install WhatsApp Business from Google Play or the App Store.
3. Open it, agree to terms, and when it asks for a phone number, enter the second one.
4. Verify with the SMS code that arrives on that second number.
5. Set a business name (this can be anything — "Personal 2" is fine).

The catch: you need a second phone number for the Business app. If you don't have one, that's where a virtual number comes in — buy a WhatsApp number for €0.40, receive the SMS, verify, done. Total cost: less than a coffee.

Limits: WhatsApp Business is designed for shops and freelancers, so it shows a "business" label and has extra fields (business hours, catalog). If you don't want a business look, this method feels awkward but functions perfectly. There's also no way to install a third WhatsApp officially — you can only have one regular and one Business.

Method 2: Companion Mode (linked device)

WhatsApp introduced Companion Mode a few years ago. It lets a single WhatsApp account run on up to four devices, all linked to one phone number. This is not two accounts — it's one account on multiple devices, which is what most people googling "second WhatsApp" actually want when they say "I want WhatsApp on my tablet too."

Steps:

1. On the second phone or tablet, install WhatsApp.
2. Open it and choose "Link to existing account" (instead of entering a phone number).
3. A QR code appears.
4. On your main phone, open WhatsApp → Settings → Linked Devices → "Link a device."
5. Scan the QR code shown on the second device.

The catch: both devices show the same conversations, the same contacts, the same everything. This is useful if you want WhatsApp Web on a work laptop or WhatsApp on your tablet, but it's not what you want if you're trying to separate two identities. It's also flaky — I've seen linked devices drop the connection every few days and need re-pairing.

Method 3: Virtual number (full independence)

The cleanest way to run a truly separate second WhatsApp identity is to sign up for a new WhatsApp account using a virtual number. This account has its own contacts, its own chats, its own profile — completely independent of your real number.

Steps:

1. Go to sms.1mail.lt/service/whatsapp/ and buy a WhatsApp number (~€0.40). Pick one of the recommended countries — UK, Netherlands, Lithuania, Ireland all have high delivery.
2. Install WhatsApp Business on your phone (so it can coexist with your main WhatsApp — see Method 1).
3. In WhatsApp Business signup, enter the virtual number from our order page in E.164 format (starts with +).
4. WhatsApp sends an SMS code to the virtual number. It arrives on our page within 30–60 seconds. Copy it into WhatsApp.
5. Complete the profile. Immediately go to Settings → Account → Two-Step Verification and set a PIN. This is critical — see below.

Why the two-step PIN is non-negotiable: virtual numbers return to the pool after use. If someone else buys the same number weeks later and tries to register WhatsApp on it, WhatsApp will send them a code — and if they use it, they take over the account. Setting a two-step PIN blocks that: they'd need your PIN to complete the re-registration.

Limits: WhatsApp is one of the strictest apps for virtual numbers. First-attempt success is ~75–85% on recommended countries — occasionally the number gets rejected and you need to retry with a different country. Our provider auto-refunds every rejection, so it's a cost of time, not money. We wrote more about why this happens in Why virtual numbers get rejected.

Pitfalls to avoid

• Don't install unofficial "dual WhatsApp" mods. GBWhatsApp, WhatsApp Plus, YoWhatsApp — these are all against WhatsApp's terms and will get your account banned. WhatsApp Business is the only official second-app option.
• Don't use free public tempsms sites for WhatsApp. WhatsApp aggressively blocks numbers from free tempsms services because they're overused. And even if it worked, anyone else on the tempsms site can see your code and log in first.
• Don't skip the two-step PIN. Without it, whoever gets the virtual number after you can steal the account.
• Don't reuse the same virtual number for another service. Once the number's associated with WhatsApp, using it for Telegram or Instagram gives all three services a data-broker join key. Fresh number per service.

FAQ

Will my contacts see the difference between WhatsApp and WhatsApp Business?

The messages look identical. The only signal is that Business accounts can have a business profile (hours, catalog). If you leave those blank, it looks like a normal WhatsApp to your contacts.

Can I run both accounts at the same time?

Yes — that's the whole point of Method 1 or Method 3. Both apps run independently, both show notifications, you can switch between them like any other pair of apps.

What if the virtual number gets recycled — do I lose the account?

Only if you didn't set the two-step PIN. With the PIN set, the account is bound to that PIN as well as the number, so a reassigned number alone isn't enough to take over. Just set the PIN in the first 5 minutes after signup.

Can I move an existing WhatsApp to a virtual number?

Technically yes — WhatsApp lets you change the number attached to an existing account (Settings → Account → Change Number). But you'll then depend on that virtual number long-term, which is fragile. Better to keep your existing account on your real number and create a new second account on the virtual one.
