How Silent.Link Solves SIM-Swap Risks and Roaming Hassles for Traveling Bitcoiners
Silent Link, a Bitcoin native SMS and mobile data company, has quietly grown into an international service provider for privacy-oriented users worldwide, at competitive rates. But how can a young company compete with the mobile data giants?
Born from the Bitcoin industry, the brainchild of cypherpunk thought leaders like Matt Odell, Silent Link is a modern mobile data and SMS company that challenges the complicated and mediocre customer service of phone service providers around the world.
A founding member of Silent Link, who asked not to be named, and thus we will call Bob, told Bitcoin Magazine in an exclusive interview the genesis story of this company that’s solving one of the most common pain points of the international and travel-savvy Bitcoiner, getting data and SMS authentication messages anywhere in the world. The company offers eSIM-only services globally, with no physical sim card support, making it an entirely digital business. Its Bitcoin native design shows up on its pricing, which Bob says has only gone down over time, already dropping 20% in 2026.
Bitcoin Native and Privacy Focused
Born during the 2020 COVID lockdowns, Bob recalled that he went on a Matt Odell podcast marathon during which he was inspired to run his own BTCPay Server instance. He figured if he could come up with a digital business that earned Bitcoin, he would have a solid way stack sats directly to self-custody.
After setting up the basic payments suite common to many Bitcoin companies, made up of BTCPay servers, an open source stack with Lightning support, full invoicing and accounting back end, Bob realised he now needed a product. It was not long before him, and his growing team realised that providing a modern data and SMS service might just be the perfect product.
Today, Silent Link offers users worldwide data rates competitive with phone service giants, as well as incoming SMS texts often needed for authentication to legacy companies like banks, and many online web platforms. The company does not offer outgoing texts, nor does it support normal phone calls. Bob explained that these are terrible protocols, fully surveilled by governments throughout the world, and his target audience uses more secure and sophisticated messaging apps anyway.
As such, Silent Link is a privacy-first Bitcoin company. Instead of connecting your phone services to your personal information, which in many countries ends up deeply integrated with the financial system, even showing up in credit scores, Silent Link provides essential services in the digital age, while collecting no personal information from its users. Bob added that “not even the local data carrier knows your phone number”.
Silent Link eSIMS can be purchased even without giving the company an email. Bob explained that if you have no user information, there’s nothing to hack and there’s no honey pot to go after, adding that so far they have received “zero requests for user information” from governments. Furthermore, it aligns incentives between the company and its users, rather than turning the user’s data into a product to be sold to third parties. According to Bob, the company is also entirely self-funded and profitable, another critical decision that he feels aligns incentives with its users, adding that “you can not serve two masters”.
Users get a special link when they purchase an eSIM, a code that they can back up in a similar way as they would store the 12 words to their Bitcoin wallet, and this simple secret information serves as their key and authentication to their eSIM service. Bob added that this model of authentication nullifies the infamous “sim card swap” attacks, which have led to multi-million dollar hacks in the industry throughout the years.
Roaming and Travel Automated
Further polishing the user experience, clearly designed to serve an audience that travels often and is sensitive to cybersecurity risks, Silent Linkautomates and hides roaming-related decisions when users move from one country to another, be it for travel or otherwise. Bob says users can expect the same phone number to work in most countries, without having to worry about getting a local temporary sim card, having to buy roaming access, getting overcharged, or having to talk to customer service to make a special purchase at all. Silent Linksimply connects to data providers in the local network and draws from the balance on the user accounts, minimising friction and staying competitive on price.
According to Bob, Silent Link can get around state firewalls, including the Chinese firewall, and users report they can use WhatsApp from Dubai, which has restrictions on Voice over IP (VoIP) protocols. The eSIM model actually has a lot to do with this censorship resistance quality unlocked by Silent Link.
Data sharing hotspot features are not throttled either, essential for perpetual travellers and those Bitcoiners hopping from conference to conference around the globe as they work online.
