EspañolCan You Use WhatsApp Without a SIM Card?
Yes, you can use WhatsApp without a SIM card in your phone: WhatsApp needs a phone number that can receive the one-time setup code by SMS or call, but that number never has to sit on a SIM inside the device you use.
Any supported number you own that receives the code works, and once verification is done the app runs over Wi-Fi or mobile data without that SIM.
What WhatsApp's own help pages say
WhatsApp's help center says you must register an active phone number and be able to receive the 6-digit code by SMS or phone call.
It also asks you to enter the number in full international format and says you can only register a number you own.
What it never asks for is a SIM card inside the phone running WhatsApp.
The code goes to the number, wherever that number lives: a second phone, a different line, or a number bought just for this sign-up.
So the honest answer to "WhatsApp without a number" is no: every account is tied to a phone number.
The answer to "WhatsApp without a SIM card" is yes, as long as the number can receive the code.
What kind of number actually works
Based on WhatsApp's list of supported and unsupported numbers.
| Number type | WhatsApp (regular app) | WhatsApp Business |
|---|---|---|
| Mobile number on a SIM in this phone | ✅ Works | ✅ Works |
| Mobile-range number that receives SMS, with no SIM in this phone | ✅ Works (keep the SMS option) | ✅ Works (keep the SMS option) |
| Landline | ❌ Not supported | ✅ Supported, with the call option |
| VoIP number | ❌ Not supported | ❌ Not supported |
| 0800, premium-rate or universal access number | ❌ Not supported | ❌ Not supported |
WhatsApp and WhatsApp Business each need their own number: one number can't run both apps.
How to register WhatsApp with a different number
- 1
Get a number that receives SMS
Use a second line you own, or a number for WhatsApp verification from SMS Falcon, paid by card or crypto.
The number shows up in your SMS Falcon account right after payment. - 2
Install WhatsApp on the device
Phone or tablet, with or without a SIM.
Connect to Wi-Fi or mobile data. - 3
Enter the number in international format
Pick the number's country in WhatsApp's list, then paste the digits exactly as they're shown.
- 4
Keep the SMS option
SMS Falcon numbers receive text messages only, so don't choose the call option.
Wait for the progress bar before retrying. - 5
Type the 6-digit code
The text appears in your SMS Falcon account.
Enter it in WhatsApp and set up your profile. - 6
Protect the account right away
Turn on two-step verification and add an email address in WhatsApp's settings, so you can sign in again later without a new SMS.
After verification: do you need to keep the SIM?
No.
Once the code is accepted, WhatsApp runs over the internet.
The SIM, or the second phone that received the code, doesn't have to stay in the device.
What matters later is re-verification.
WhatsApp can ask for a new code when you reinstall the app or move to a new phone.
A number bought for one verification stays active for about 20 minutes, so after that you won't receive another code on it.
That's why step 6 matters: with two-step verification and an email on the account, you depend much less on that number.
If you want to keep the same number for longer, see renting a number.
If the code never arrives at all, the verification code checklist covers the usual causes.
On SMS Falcon, a number that never receives its code is refunded automatically.
