I’m trying to buy a roaming package. The link upc.ch/roaming took me to Sunrise roaming packages. I wanted to send a text to 5522 with message “unlimited europe”. I receive a pop-up message that is in the title, the message was not sent even I tried several times. It first warned me that this will result additional charges and I approved that. The messages app now has permission to send premium messages. I can send usual messages e.g. to my wife. How can I buy the sunrise package? Phone is Moto G100.
