You can get a second number with a second SIM or eSIM, a calling app, or a private number you rent. Which is best depends on whether it must receive codes.
| Option | Cost | Receives app codes? | Best for |
|---|---|---|---|
| Second SIM or eSIM | Monthly plan | Yes, reliably | A long-term second line |
| Calling app number | Often free | Often refused (VoIP) | Calls and texts with people |
| Rented non-VoIP number | Per day or per code | Usually | Sign-ups and short projects |
| Free public number | Free | Rarely; anyone can read it | Quick tests only |
Most recent phones hold two lines, one physical SIM and one eSIM, so a second number does not need a second phone.
Note which accounts use which number. When a second number ends, you then know exactly which accounts to update, instead of finding out when a code goes missing.
A second SIM or eSIM, a calling app, or a private number you rent.
Mobile numbers usually can; calling-app numbers are often refused.
Not with a dual SIM or eSIM phone.
