Generically, Roamaphobia is exemplified by 4 Roamaphobia types:

Wi-Fi Hunter: Those who turns their holidays into a jungle hunt for free Wi-Fi
Café Dweller: Those who linger at a café forever just to use free Wi-Fi
SIM Swapper: Those who bring many overseas local SIM cards on holiday trips just to save a few bucks
Latergrammer: Those who only upload all the holiday photos as #latergram onto social media and flood their friends once they get back to hotel (with free wi-fi/back home)
