MTX Connect eSIM funktioniert nicht

"For my first time in Europe — where public Wi-Fi isn't as widespread as I'm used to back home — it was so helpful to have a stable 3G connection I could use to get hold of maps, find places to eat on Instagram or Foursquare, and keep in touch with my host on Airbnb.  MTX Connect is Europe's mobile internet carrier, with a fast and secure network worldwide (3G/LTE).  "With MTX Connect, everything is simple — there's no headache which comes from searching for a mobile phone shop, find the best deal, or sign a contract.  There's a fixed rate, you can “share” your data allowance by swapping the SIM card to different phones, and the card itself connects to the 3G network of the country you're in.  Receive 350 Mb at maximum speed, then get unlimited online access at 64Kb / s. 24 hours unlimited access to our top-speed internet, wherever you are.  With an MTX Connect SIM Card or eSIM, you're always online – without the hassle of roaming charges.  Enjoy even more data in any country covered by MTX Connect for two weeks.  Use our app to monitor data use in real-time, top-up your balance, and access our support services.  "MTX Connect SIM cards are specifically designed for traveling and working throughout Europe.  You can activate SMS Subscription through your Personal Account page or MTX Connect app.  Choose one of the fixed tariffs to suit your needs, then play, chat, surf and watch videos across the globe.  With MTX SMS Number Subscription you can choose UK or Luxembourg phone number and get SMS from people, banks or web-services with 2FA anywhere around the world.  Finding an open network used to take up a lot of precious time, and checking that everything worked and loaded properly was an adventure in itself.  A special thank you to the team at MTX Connect!  "Before I found out about MTX Connect, I only ever used Wi-Fi.  Now I have the internet at my fingertips everywhere I need it". —© Denis Mamin, Instagram @ the.
