  • “Theo was amazing, he really put the effort to figure out what was the issue with my connectivity, and while doing so he secured that I have temporary card. I am the regional head of CX team in IKEA, and I know when professional support customer experience has been offered. Thank you once again!”

  • “I used it while traveling in Egypt. The internet was very fast without any slowdowns, and the setup guide was easy to follow. Thank you!”
    SNSerhii N.1 week in Egypt★★★★★
  • “Used it twice this year in Canada - first time when my parents came to Canada for a few weeks - they only needed internet, so it's much cheaper and easier to setup (it was like 3-4 minutes with Apple Pay) than buying something from a local carrier...”
