Quackr's free numbers are public and shared, and its page says they “get rotated at least every 30 days”. Its paid plans give “your own dedicated anonymous phone number that only you have access to”. Numero eSIM sells a private number you keep, that calls and texts, in 39 countries from $3.99 a month.
The row that decides this comparison is a fact Quackr publishes itself: its free numbers are public. Anyone can open the site and read the messages arriving on them, and the numbers rotate at least every thirty days. For a throwaway signup that is fine and free. For anything attached to an identity, a bank, a wallet, a marketplace account or a recovery number, the code is visible to strangers and the number stops being yours within a month.
Who can read the messages on a Quackr free number?
Anyone, because the free numbers are public and shared. Quackr's paid plans fix that with a dedicated number only you can access. A Numero eSIM number is private from the first day, in all 39 countries, and each country page states whether it receives SMS and is listed for WhatsApp.
Can you send a text or take a call on Quackr?
Quackr is receive-focused. Its page says of sending that “Some providers will let you send messages but this usually incurs a cost”, and calls are not stated. A Numero eSIM number sends SMS, and makes and receives calls, in every one of its 39 countries.
How long is the number yours?
On Quackr's free tier, until it rotates, which happens at least every 30 days. A Numero eSIM number stays yours for as long as you pay for it, with toll-free lines in eight countries and a US area code of your choice if you want one.
Quackr offers free public receive-SMS numbers plus paid dedicated ones. The table compares it across all four Numero eSIM product lines; Quackr competes in part of one of them.

Quackr publishes the safety fact itself: the free numbers are public and rotate monthly. That makes them the wrong tool for anything you might need to recover later, and Quackr's own paid tier exists to solve exactly that. Numero eSIM starts where the paid tier does, with a number only you can see, and adds calls, outbound texts and 39 countries.
A Numero eSIM number receives, sends, rings and stays yours for as long as you pay, with data in 181 countries and a full eSIM in 188 attached to the same account.
Quackr states all of the above, promises a permanent free tier, and sells a paid dedicated anonymous number for people who want privacy without a contract.
