Why This Matters
Many apps and websites ask for a phone number—even when it’s not really needed. But using your main number can lead to:
Spam calls and texts
Privacy leaks
Account lockouts if your number is flagged or reused
A second number helps you stay private, organized, and safe.
The 3 Main Types of Second Numbers
1. 
App-Based Numbers (Easy to Get, Sometimes Blocked)
These are free or cheap apps that give you a phone number inside the app.
| App |  Good For |
 Not Great For |
|---|---|---|
| Google Voice | Long-term calls/texts (US only) | Bank OTPs, abroad access |
| TextNow | Temporary signups | WhatsApp, 2FA logins |
| TextMe | App signups | Uber, secure platforms |
| Hushed | Travel use, throwaway use | Google, Facebook |
| Talkatone | Basic second line | Sensitive apps |
| MySudo | Multiple profiles, privacy | Services that detect VOIP |
Heads Up:
Many apps and banks block VOIP numbers. These might work at first, then stop.
2. Real SIM or eSIM Numbers (Fully Trusted Everywhere)
These use real mobile networks—just like your regular SIM.
| Service | Highlights |
|---|---|
| Tello (US) | Starts at $7/mo, supports eSIM + Wi-Fi calling |
| RedPocket (US) | Works outside US with Wi-Fi |
| Three HK (Global) | $35/year, includes Hong Kong number, works worldwide |
7-Eleven SpeakOut  |
$25/year, receive texts free, long validity |
| Chatr / Telus |
Good 1-year plans, trusted by banks and apps |
Use dual SIM phones or load eSIMs to carry multiple numbers.

DIY / Custom Setup (Advanced Users)
For people with technical skills who want full control.
- Use Termux + Python + Ngrok on Android to create your own SMS server
- Insert a SIM in a 24/7 phone and use API to forward messages
- Use VOIP.ms + SIP App (like Groundwire) to receive calls/texts via internet
Not beginner-friendly. Only worth it if full customization is needed.

- eSIM: A digital SIM you can load into your phone without needing a plastic card
- 2FA: Two-Factor Authentication (e.g., SMS code to verify login)
- Burner: Temporary number used for short-term signups or anonymity

No need to overthink it—just pick what fits your goal and set it up.
