Add a phone to Steam Guard with a rented number
Creating a Steam account needs an email and nothing else, so this page is not about registering. It is about the phone Steam asks for afterwards: without the Steam Guard mobile authenticator every trade and every Market listing sits on a 15-day hold, and the authenticator will not turn on without a number. Steam refuses VoIP numbers, which is the one thing worth checking before you buy anywhere.

How it works
Rent a real carrier line
Steam rejects VoIP numbers outright. Every line in this catalogue is a real operator subscriber rather than a software number, which is the part Steam checks. Choose on price otherwise — Indonesia and Myanmar are the lowest monthly.
Add the number in the Steam app
Steam Guard lives in the mobile app, not the desktop client. In the app, open Steam Guard and add the phone in international format without the leading zero.
Read the code on the order page
Steam sends the confirmation SMS to the line. It appears in your order page. No SIM, no device.
Wait seven days before you count on it
The authenticator only clears trade holds once it has been attached for seven days. Trades made inside that week still carry up to the full 15-day hold, so turn it on before you need it, not on the day of a sale.

What can go wrong
Steam says the number cannot be used
Almost always a VoIP line. Steam checks what kind of number it is, not who owns it, and refuses software numbers. A real carrier subscriber passes.
The SMS never arrives
Check the country code first. If it is right, Steam has rate-limited repeated attempts — wait, then request once more rather than pressing again.
Trades are still held after adding the authenticator
That is the seven-day rule, not a fault. Holds clear once the authenticator has been on the account for a week.
Frequently asked questions
Do I need a phone number to create a Steam account?
No. An email address is enough to sign up and to buy games. The phone is for Steam Guard, for trading and the Market, and for a few games that ask for one to play online.
Does Steam accept a rented number?
Steam checks whether a number is a real carrier line, not whether you own it. It refuses VoIP. The lines here are carrier subscribers.
What happens if I stop renewing?
The authenticator keeps working on the device it is installed on, but you lose the number for recovery. Before the rental lapses, save your recovery code or move Steam Guard to a number you keep.
Would a one-time number do?
It gets the authenticator switched on. It will not be there when Steam asks to confirm a device change or a recovery, which is exactly when losing access hurts.
One number, how many Steam accounts?
One. Steam binds the phone to a single account.
