Connectivity Insights
Trusted news, guides and tools for travelers, enterprises and the global connectivity industry.
Travel connectivity is changing quickly
For travelers
That is where Alertify comes in. We help travelers understand what is actually worth their attention, from eSIM plans and roaming options to travel technology, connected devices and services that can make a journey easier. The focus is practical: clearer choices, fewer surprises and better ways to stay connected wherever the trip leads.
For businesses
For businesses, the challenge is different. The market can shift before a trend has even become obvious. New distribution models appear, customer expectations change, connectivity moves into products that once had nothing to do with telecom, and partnerships can suddenly create entirely new revenue opportunities. Alertify follows those changes early, connects the dots and looks at what they could mean in practice.
Where the markets meet
We cover the space where telecom, travel and technology increasingly overlap: eSIM and roaming, embedded connectivity, mobility, travel tech, digital services and the business models behind them. The aim is not simply to report what happened, but to make the market easier to understand while there is still time to act.
From decisions to opportunity
For travelers, that means making smarter decisions with more confidence. For businesses, it means recognizing important shifts sooner, understanding where the real opportunities are and deciding how to respond before the market moves on.

The race to the bottom won’t build the next travel connectivity leader
Nomad eSIM’s Louis Sim talks price pressure, network control, loyalty and why Nomad is increasingly comfortable becoming the invisible connectivity layer behind airlines, banks and travel platforms. The bigger question is whether the next eSIM winner owns the traveller — or powers the brand that already does.

Travel eSIM Opened the Door. Now Everyone Wants In.
Opera is turning the browser into a connectivity storefront, Lidl is bringing retail economics into mobile, and Network APIs are reaching their next challenge: distribution. eSIM changed more than roaming — it changed who gets to package, surface and sell connectivity.
