Messages from magnum

MAGNUM is a company or service that sends SMS messages containing activation codes for an unknown account. The content of the messages does not provide any information about what kind of product, app, website, campaign or service MAGNUM offers. However, based on web search results it can be seen that "Magnum" has multiple meanings such as being used to describe large wine bottles and powerful firearms cartridges. Additionally there are businesses with Magnum in their name including firearm makers and photojournalist cooperatives among others. It's unclear if these definitions have anything to do with the sender of the SMS messages received from "MAGNUM".
