Travel, Hospitality & Logistics

Airlines, hotel groups, online travel agencies, cruise lines, freight forwarders and last-mile delivery networks share a common problem: their customers and assets are constantly moving across borders, time zones and mobile networks. A gate change has to reach a passenger on a foreign SIM in seconds. A guest wants to call the hotel on a local number. A container needs to report its position from a port on another continent. Dollu is built for exactly this kind of multi-country operation, with numbers in 110+ countries, SMS connections into 800+ operators and IoT connectivity that roams without bilateral contracts.

For customer communications we deliver booking confirmations, itinerary changes, check-in reminders and delivery updates over direct international SMS routes, WhatsApp and RCS, with automatic fallback so the message arrives even when a traveller has switched to a local SIM. Local, toll-free and mobile numbers give every property, hub and market a familiar caller ID, and a cloud contact centre routes calls to whichever team is awake, with IVR and conversational AI in the languages your guests speak.

For assets and operations we supply IoT eSIMs and multi-network SIMs for trucks, containers, trailers, vending and kiosk equipment, a fleet and asset tracking platform with geofencing and telemetry, and SD-WAN and managed Wi-Fi for hotels, depots and airport lounges. All of it is monitored from a 24×7 NOC and covered by one agreement, one portal and one account manager, so a business operating in thirty countries deals with one telecom provider rather than thirty.
