Most travel calls are short but happen at the worst possible rates: your home carrier's international roaming, or a hotel phone at a marked-up per-minute price. And a foreign local SIM often can't easily call yet another country. Hyallo needs only the Wi-Fi that's usually already free.
No local SIM required — any internet connection is enough to place a call.
Hotels, tour desks, airlines and consulates almost always use a regular landline or mobile — Hyallo dials exactly that.
Pay-as-you-go with no subscription — sign up before the trip, use it a handful of times, and stop without cancelling anything.
Just an email — takes a minute at home on a good connection.
Hotel, airline, tour operator, your embassy — add them to Hyallo's contacts before you go.
Airport, hotel, café — connect and dial straight from your browser.
A traveler's calls tend to cluster in one stressful day: confirming the hotel can still take a late check-in, calling the tour operator when the pickup point changed, ringing the airline about a delayed connection, and — worst case — getting your embassy or a local emergency line on the phone. Every one of those is a normal phone number, and every one of them is reachable the same way: open Hyallo on the airport or hotel Wi-Fi, dial, and pay only for the minutes actually used.
Real per-minute rates, in your currency — no plans, no bundles.
No — Hyallo only needs an internet connection, so hotel or airport Wi-Fi is enough. A local SIM only helps if you need mobile data away from Wi-Fi too.
Yes — an embassy uses a normal phone number in that country, which Hyallo can dial like any other.
Yes, up to one minute, for destinations priced at 25¢/min or less, with no credit card required — enough to test call quality before you travel.
