Quackr offers phone numbers for verification, both free public ones and private ones you keep for a while. If you are weighing alternatives, what matters is usually whether the number is shared, how long you need it and how you pay. Here is what Quackr states on its own homepage, read on 31 October 2026, next to what SMS For U does.
Before you switch
- Decide if you need one code or a number to keep.
- Check that the service you sign up to is listed for your country.
- Read the refund sentence word for word.
- Test one number before you switch for good.
What Quackr says about itself, 31 October 2026
The site is in nine languages, among them Portuguese, Arabic, Japanese and Hindi.
It links to a Quackr app in the App Store and on Google Play.
It lists free temporary numbers in the USA, the UK and 30 other countries, and updates them every month.
It sells a private non-VoIP number for a week, a month, six months or a year, and says that every plan receives unlimited verifications.
It takes card, PayPal or crypto, offers bulk discounts and an API, and says more than 3 million people use it.
All of this is from the Quackr homepage, read on 31 October 2026. It is a description, not a review.
Where Quackr can suit you better
You want to keep one number for weeks or months and use it for several sign-ups. Quackr sells exactly that, and SMS For U does not: our number is for one verification.
You want to look at public numbers without paying, or to pay with crypto or through an API. Quackr lists those, and SMS For U does not offer them.
Where SMS For U differs
One number for one verification, not a plan that runs for a week or longer.
The number is reserved for you. Nothing is shown on a public page, so your code is not visible to others.
Purchases run through Apple in the iPhone app and through Google Play in the Android app, and a single purchase needs no SMS For U account.
If no code arrives, you do not pay. The app shows how to cancel the number.
No prices, no success rates
Prices and success rates: both depend on service and country and change by the hour. Ours are shown in the app before you confirm.
Common questions
Does SMS For U have free numbers?
No. Free public numbers show every message to everyone who opens the page. Ours are private and you pay for one verification.
Can I keep the number?
No. Our number is for one verification. If you need a number for months, a rental plan fits better.
Does SMS For U guarantee a code?
No. Nobody can promise that a service accepts a given number. What we do promise: if no code arrives, you do not pay.
