She spent two decades building the case that the best SIM card is the one you never have to think about. SIMO's patented virtual SIM platform connects to 300+ mobile carriers across 140+ countries - switching networks in milliseconds, invisibly, automatically. No plastic. No contracts. No roaming surprises.
Jing Liu is running SIMO at the moment the world finally caught up to her thesis. The premise she locked into in 2008 - that mobile connectivity should be carrier-agnostic, software-defined, and invisible to the end user - has become the default assumption for enterprise IoT, automotive, and global travel tech. She got there first.
SIMO's AI-powered vSIM (virtual SIM) platform is the connective tissue for an expanding universe of use cases: the Solis Go hotspot that doubles as a power bank, the Solis Hub providing backup connectivity for homes and businesses, IoT devices that switch carriers automatically in milliseconds, and enterprise fleet management that treats coverage like a software API rather than a hardware problem.
The pivot from consumer travel gadget to cloud connectivity infrastructure happened gradually, then all at once. Today, SIMO's platform spans South San Francisco, Berlin, and Shenzhen - three offices that mirror the global nature of the problem Liu set out to solve. She was at CES 2025, talking about the shift toward domestic connectivity backup and AI-driven network selection. The company is not done growing.
The Solis Go connects up to 10 devices simultaneously, switches between T-Mobile, AT&T, and Verizon in real time, and fits in a jacket pocket. It also charges your phone. Jing Liu's product team built the thing she always wanted: invisible, global, just works.
"We believe that our next 100 million users will come from IoT."- Jing Liu, Founder & CEO, SIMO
Jing Liu's first professional chapter was at Levi Strauss & Co., where she worked as a Senior Consultant from 1996 to 1999. Fashion. Consumer goods. Not telecom. The pivot was sharp: she moved into Vice President roles at Asia-Links, building out her understanding of how connectivity worked (and failed) across borders - particularly between Asia and North America.
In 2004, before the iPhone existed and before 4G had a name, Liu founded MINO Wireless. The company built VoIP services for BlackBerry phones targeting large enterprise customers. That experience - watching enterprise clients lose connectivity the moment they left their home country, paying absurd roaming fees, juggling multiple SIM cards - planted the seed for everything that followed.
By 2007, she had shifted to the CTO role at MINO as the company matured, and by April 2008 she was done. MINO was a stepping stone. What Liu actually wanted to build was bigger: a platform that made the question "which SIM do I use?" as irrelevant as "which server should my email hit?" She founded SIMO that same year, in San Francisco, with a thesis that would take another decade to fully prove out.
The vSIM (virtual SIM) technology that SIMO patented is the core of everything. Instead of embedding a physical SIM tied to one carrier, SIMO's devices connect to a cloud platform that maintains live relationships with 300+ mobile carriers across 140+ countries. When a device powers on in Tokyo, or Johannesburg, or rural Montana, the AI selects the best available network in milliseconds - based on real-time signal data, historical performance, and cost optimization.
No physical SIM to swap. No carrier contract to negotiate. No roaming surcharge to dispute with an expense report. The carrier relationship is SIMO's problem, handled at the platform level.
Active carrier integrations across every major market. SIMO's coverage map reads like an airline route network - except the latency is measured in milliseconds.
AI-driven network selection runs in the background, constantly. When signal drops, the platform switches carriers before the user notices a gap.
The "SIM" is software, living on SIMO's cloud platform. No hardware to manage. No slots to open. The device just connects.
vSIM technology is protected by patents in the US and Europe. SIMO successfully defended its IP in a 2019 infringement case, forcing a competitor to change its technology.
For IoT and enterprise customers, SIMO is a SaaS connectivity layer - device provisioning, carrier selection, data management, all via API.
Supports both 5G and 4G LTE networks across the carrier network, with fallback handling built into the platform logic.
The range of SIMO's partners tells the story of the platform's ambition. It's not just traveler gadgets. It's automotive, enterprise chipsets, and global carrier infrastructure.
SIMO's vSIM technology embedded in the Acer TravelMate P4 14 laptop, expanded to eight new markets in 2025. Connectivity built into the chip, not the SIM slot.
SIMO Inside integration in Rivian vehicles. Always-on connectivity for the EV ecosystem, switching carriers based on location - handled by SIMO's cloud platform.
SIMO's vSIM embedded in the MindOne card-sized AI smartphone, enabling always-on connectivity for AI applications without a physical SIM card.
Partnership with one of Europe's largest telecoms, extending SIMO's carrier network depth across European markets.
The Levi's chapter. Before any of the wireless work, Jing Liu was a consultant at Levi Strauss & Co. The brand that invented the 501 jean. She went from denim to data SIMs without a direct route - which is, in retrospect, exactly the kind of non-linear path that leads to non-obvious ideas.
Three names, one thesis. MINO Wireless. Skyroam. SIMO. The company went through brand evolutions, but the underlying bet never changed: connectivity is a software problem. Liu just kept building until the world agreed.
The Indonesia gamble. In 2018, Liu personally navigated the Indonesian government's regulatory process to get vSIM app approval. The country has 200+ million mobile users. Regulatory approval in a market that size isn't a checkbox - it's a campaign.
The Solis Go doubles as a charger. The hotspot product Liu launched at CES 2024 has an 8,000mAh battery built in. It connects up to 10 devices and charges your phone while doing it. The product philosophy in hardware form: do more with less.
The patent war. In 2019, SIMO won a patent infringement verdict that forced a competitor to change its WiFi hotspot technology. This wasn't a side story - it validated the uniqueness of the vSIM architecture that Liu had spent over a decade developing.
CES, every year. Jing Liu and SIMO have been a recurring presence at CES, the annual consumer electronics show in Las Vegas. The 2024 appearance featured the Solis Go launch. The 2025 appearance focused on AI-driven always-on connectivity. She treats the show as a product launch platform, not a networking event.
When Jing Liu says her next 100 million users will come from IoT, she's describing a fundamental shift in who SIMO's platform is for. The original Skyroam customer was a frequent traveler who needed WiFi in 30 countries a year. That customer still exists, but the IoT opportunity is orders of magnitude larger: connected cars, industrial sensors, logistics trackers, smart home devices, medical equipment in the field.
All of those devices need the same thing - reliable, carrier-agnostic connectivity that switches networks when signal drops and doesn't require a human to manage a SIM card. SIMO's platform was built for exactly that. The consumer product line (Solis Go, Solis Hub) generates revenue and brand awareness. The enterprise and IoT layer is where Liu is building for the next decade.
The MediaTek partnership signals the direction: if SIMO's vSIM can be embedded at the chipset level, connectivity becomes infrastructure - invisible in the same way TCP/IP is invisible. That's the end state Jing Liu has been working toward since 2008. The SIM card problem, solved in software, at scale.
