TextNow gives you a free US number with talk and text on its own nationwide network, and cheap calls to 230+ countries; the number, the plans and the 5G data are all US products. Numero eSIM sells the number itself in 39 countries from $3.99 a month, with travel data in 181 countries and a full eSIM with a number in 188.
A free number that makes real calls and sends real texts is a strong offer, and TextNow has built a large business on it. The boundary is national. If you live in the US and want a second US line for nothing, TextNow is the obvious choice. If you need a line that exists outside the US, or a number people in another country can call back, it has no product for that, and that is the gap Numero eSIM fills.
Can you use TextNow outside the US?
TextNow's number, its talk and text, and its 5G data are US products on a US network; its own wording is “Call and text from anywhere in the US, plus call Canada for free”. Outside the US, the offer is outbound calling to 230+ countries, not a number in any of them. Numero eSIM sells numbers in 39 countries, so a UK, Brazilian or Australian line that people can call you back on is something you can buy.
Does a TextNow number work for WhatsApp?
TextNow's site does not say. Numero eSIM publishes the answer per country: WhatsApp is listed on 11 of its 12 mobile-number countries, every one except Nicaragua, and on the Denmark and Colombia toll-free lines. The WhatsApp number pages say which before you pay.
What does a paid number buy that a free one does not?
TextNow is free. $3.99 a month with Numero eSIM buys a number in 39 countries instead of one, toll-free lines in eight, a data eSIM in 181 countries, and a full eSIM in 188 that carries data, minutes and a real number at once. TextNow answers “I want a second US number for free.” Numero eSIM answers “I need to be reachable in another country.”
TextNow is a free, ad-supported US phone service. The table compares it across all four Numero eSIM product lines; TextNow competes in one of them, virtual numbers, and touches international calling.

TextNow's international story is outbound calling to 230+ countries; it sells no number outside the US. Numero eSIM sells the number itself in 39 countries, and the difference shows up the first time someone abroad needs to call you back. On the US side the two overlap: both give you a US line that receives SMS, TextNow for free and Numero eSIM with a choice of area code across nine cities from $3.49 a month.
TextNow sells one thing well. Numero eSIM puts the number next to travel data in 181 countries and 7 regions from €3.50, unlimited plans in 14 countries plus Europe, a full eSIM with a number in 188 countries from €16.00, and 17 local and 2 international calling plans. If you travel, the same account covers the trip.
For a US-based user who wants a second line at zero cost, TextNow is difficult to argue with. Numero eSIM is a paid product and should be judged on what the money buys: reach outside the US, and connectivity on the same account.
Aircall, Dialpad and RingCentral sell phone systems per seat, with licence minimums and paid add-ons. Numero eSIM sells one number to one person from $3.99 a month.
Free numbers that are public, shared and rotated at least every 30 days; paid plans add a dedicated line. Numero eSIM sells a private number in 39 countries.
A free US number for individuals, and only in the US. Numero eSIM sells a number in 39 countries from $3.99 a month, with travel data and a full eSIM on the same account.
