Temporary virtual number vs TextNow
TextNow is one of the best-known ways to get a free second number in the United States and Canada, so it is often the first thing people try when a sign-up asks for a phone. It works well for texting friends, but verification is a different story: TextNow numbers are VoIP, and plenty of apps block VoIP. This page compares TextNow with a Noir SMS temporary number on acceptance, cost, how long the number lasts and what each one is actually for, so you can choose sensibly for your own accounts.
Quick answer
TextNow is a free, ad-supported app that gives you a US or Canadian VoIP number for calls and texts, and the number can be reclaimed if you stop using it. Because it is VoIP, many apps refuse it at sign-up. A Noir SMS temporary number is a carrier mobile number rented for one verification, refunded automatically if no SMS arrives. Use TextNow as a casual second line; use a temporary number when an app blocks TextNow.
Side by side
Why TextNow numbers fail verification
Sign-up systems often check whether a number belongs to a mobile carrier or a VoIP provider. TextNow numbers come back as VoIP, and services that care about fake accounts frequently block them. You may see an error, or the code may simply never arrive.
TextNow numbers are also handed out again after other users let them go, so a number you receive may already be linked to an account on the app you are trying to join.
Inactivity and number reclaim
Free TextNow numbers can be reclaimed if you do not use them for a while; the exact window is set by TextNow and has changed over time. TextNow sells an option to keep your number. If you rely on a TextNow number for account recovery and it is reclaimed, you can lose access to that account.
Where a temporary number fits
Noir SMS gives you a mobile number for one verification on one service. You see the code in the dashboard, and you can request another SMS on the same number while it is still active. If nothing arrives within 20 minutes, the charge is refunded to your balance.
It is not a phone line: no calls, no outgoing texts, and the number is recycled later. It is meant to get you through a verification step for your own legitimate account, not to replace a number you keep.
Verdict
Pick TextNow if you want a free second number in the US or Canada for everyday calls and texts and you do not mind ads or checking in regularly so the number is not reclaimed. Pick a Noir SMS temporary number when an app rejects your TextNow number, when you need a UK or other country number, or when you only need a single code. Neither is ideal as a recovery number for an account you keep for years; your own SIM or an authenticator app is safer for that.
Frequently asked questions
Is TextNow really free?
Yes, the basic service is free and supported by ads. TextNow also sells paid options, such as removing ads or keeping your number. Prices and plans change, so check TextNow directly.
Why won't WhatsApp or other apps accept my TextNow number?
Many apps block VoIP numbers to reduce fake accounts, and TextNow numbers are VoIP. The block may show as an error or as a code that never arrives. A mobile number is usually needed instead.
Can I lose my TextNow number?
Yes. Free TextNow numbers can be reclaimed after a period of inactivity. Any account that relies on that number for codes could become hard to recover.
Does Noir SMS let me text back or call?
No. Noir SMS numbers only receive SMS. They are for verification codes, not conversations.
Can I keep a Noir SMS number like a TextNow number?
No. Each number is for one verification and is recycled by the provider later. For an account you plan to keep, add your own number, email or authenticator app after you sign up.
