silent.link sells anonymous data eSIMs that work in “160+ countries” and a US +1 number on its US.PLUS plan. Its own page states that voice is not available and that outbound SMS is not allowed, so the number receives texts and does nothing else. Numero eSIM's numbers place calls, answer calls and send texts, in 39 countries against silent.link's one, from $3.99 a month.
silent.link states its limits plainly, and they are severe. Its US number receives inbound texts and nothing else: the page states that voice is not available, that legacy mobile voice call services are not provided, and that outbound SMS is not allowed to prevent spam and abuse. That makes it a verification receiver attached to a data plan. The trade is explicit on its own site: you give up calling and outbound texting.
What can the silent.link number do?
Receive inbound SMS. It cannot place or take a call, and it cannot send a text. A Numero eSIM number does all three in every one of its 39 countries, and each country page states whether it receives SMS and is listed for WhatsApp.
How many countries can the number be from?
One: a US +1 number on the US.PLUS plan, whose price is not shown on the page. Numero eSIM sells numbers in 39 countries with published prices, toll-free lines in eight and a choice of US area code.
What is the trade-off?
silent.link's positioning is anonymity and its data pricing is sharp. Numero eSIM sells the other side of that trade: a working line, with a full eSIM in 188 countries that carries data, minutes and a number together, and a data eSIM in 181.
silent.link is a privacy-first, anonymous eSIM provider. The table compares it across all four Numero eSIM product lines; silent.link competes in two of them.
