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.

What comes after travel data? Numero is betting on the global telecom account
Ibrahim Rayyan talks subscriptions, virtual numbers, customer retention and why Numero eSIM wants to build a telecom relationship that survives the trip. With around 65% of its revenue coming from subscription-based services, Numero’s bigger bet may not be travel data at all.

Good digital telecom should hide complexity, not responsibility.

The Cow, the Credit Card and the Satellite
A Brazilian cow, a credit card and a satellite are unlikely telecom business partners. Yet Acceleronix, iBOI and Quectel are bringing eSIM to cattle tracking, Wise is adding custom connectivity plans, and FLOLIVE and Skylo are expanding cellular-satellite IoT. Add Air India entering travel eSIM and Holafly bundling healthcare, and one question stands out: who captures the value when connectivity serves so many different businesses?
