Telecommunications or more specifically telecommunications for a messenger is not found in list, however on the other hand, "Technology & Programming" is there and "Messaging" is actually more precisely expressed by: "Chat Apps / Messengers" is not, however part of communication, Communication Apps would be in Social & Community as well Telecommunications can be said to be included under the broad category of technology

Based on the provided information, we can infer that the category "Technology & Programming" is most relevant to this. However, since the category is not specified in the list, it could be sub-categorized within or combined with: "Mobile Phones" or "Smart Phones", we would need a word describing the phone more detailed or specifically it could be a category like "Telecommunications" or "Electronics" however, the most fitting possible with supplied 'IND' to the name to this is 'Technology & Programming', other match closely could be "Telecommunications"

Technology & Programming This category fits as the topic is related to virtual SIM, which can be categorized under technology (specifically telecommunications technology) and programming (as it often involves coding and setup).
