How to Get a Second Phone Number Without a SIM Card
Get another phone number for calls and texts without adding a physical SIM card or carrying another device.
Quick answer
A second-number app can give you another number without a physical SIM card. The number works through Wi-Fi or mobile data inside the app. An eSIM also avoids plastic, but it is still a carrier SIM and usually comes with another mobile plan.
People often use “without a SIM” to describe two different setups. A virtual number app does not add another carrier identity to the phone. An eSIM does, even though there is no removable card.
Use an app for a separate calling and texting line
HashPhone lets you choose an available US or Canadian number and use it for one-to-one calls and SMS. Your existing carrier number and SIM remain unchanged.
- Download HashPhone.
- Create your account.
- Choose from the numbers currently available.
- Review the introductory offer and renewal terms.
- Call and text from inside the app.
This is useful when you want a different number for work, online selling, travel arrangements, signups, or new contacts but do not need another data plan.
What the number needs to work
An app-based number needs an internet connection. That can be Wi-Fi or data from your existing mobile plan. Incoming calls also depend on notifications and background permissions being enabled.
It does not replace carrier emergency calling. If you need a complete second mobile service, including independent data and native carrier features, consider an eSIM or another carrier line.
Can a number without a SIM receive verification codes?
HashPhone can receive regular SMS and many verification messages. The service sending the code may identify and reject virtual or VoIP numbers, so test important accounts and keep another recovery method.
App number or eSIM?
Choose an app for quick setup and a focused second identity. Choose an eSIM when you need another carrier subscription, native dialer support, data, or broader compatibility with systems that require a mobile-classified number.
