Welcome To The King Sims Experience
Step 1: It All Starts With The King's Travel eSIM
Convenience is King 👑
The King has worked tirelessly to bring you an easy & smooth travel experience. With a click of a button, and a scan of an easy QR Code. You can say “Goodbye” 👋 to waiting for a SIM Card before leaving to China 🇨🇳 Hong Kong 🇭🇰 or Macau 🇲🇴. You don’t even need to search for a SIM card at the Airport… say hello to a new way of traveling like a King 🤴 & 👸 Queen.
Step 2: *Ding* You’ve got an email! It looks like it’s from the King 👑
Don't Keep The King Waiting…
Open it up… Do you like what you see? It may not be as exciting as our physical King SIMs, but this neat little QR code has HUGE benefits. Save it and don’t forget to open your email or King Sims app with this QR code when you land overseas. Trust us, you’ll need it.
Step 3: Land Overseas… Scan & Play 🤳 Be On Your Way!
"TOUCH DOWN!" 🛬
When the plane lands, connect to the free airport Wi-Fi. Open your email with your King Sims eSIM and scan the QR code. Go to your "Mobile Data Roaming" settings and turn your "data roaming" to 'ON' Before you even leave the Airport, your eSIM should be up and running, and your phone buzzing 📲 from all the missed notifications on your flight ✈️
Step 4: Walk out of the Airport Like a King & Queen
You've Earned Your Crown, Now Wear It! 👑
