Instead of inserting a plastic SIM card, you download the mobile plan to your phone, with one tap or by scanning a QR code.<\/p>\n

How it works with TraveleSIM<\/h2>\n
    \n
  1. Check your phone.<\/strong> Your phone must support eSIM and be unlocked. Check compatibility<\/a>.<\/li>\n
  2. Choose a plan.<\/strong> Pick your destination, the amount of data and how many days you need in our eSIM store<\/a>.<\/li>\n
  3. Install it before you travel.<\/strong> Your eSIM arrives by email right after payment. Install it while you still have Wi-Fi at home.<\/li>\n
  4. Turn it on when you arrive.<\/strong> Switch your mobile data to the TraveleSIM eSIM and turn on data roaming for it. That is all.<\/li>\n<\/ol>\n

    Why travel with an eSIM?<\/h2>\n
      \n
    • No local SIM card to find, no passport registration at a shop counter.<\/li>\n
    • Your own number stays in the phone, so calls and SMS from home (for example bank codes) still reach you.<\/li>\n
    • Clear prepaid prices, no roaming bills afterwards.<\/li>\n<\/ul>\n

      TraveleSIM.ch is run by ConnectLingua S\u00e0rl, a Swiss company based in Bulle. Everything happens online: there is no shop to visit.<\/p>\n","protected":false},"excerpt":{"rendered":"
