What travellers say
Trusted by thousands of travellers worldwide
"Used VAYO for my trip to Japan and it worked perfectly from the moment I landed at Narita. Setup took about 2 minutes. I will never go back to buying local SIMs at the airport."
"Travelled through 6 European countries over 3 weeks with the EU plan. It switched networks smoothly every time I crossed a border and I never had to touch a setting."
"Checkout was super easy and the QR code arrived in my email within seconds. Had solid 4G in Bangkok, Phuket, and Chiang Mai the whole trip. Really happy with it."
"I travel for work every month and VAYO has completely replaced my old roaming setup. The global plan saves me a lot compared to what my carrier used to charge."
"Used it in Turkey and had fast 4G in Istanbul and even out in Cappadocia. I messaged support with a question and they got back to me within a few minutes. Really impressed."
"Visited the US and Canada on the North America plan. Fast speeds everywhere, including on road trips between cities. I wish I had found this service a lot sooner."
