Sweden is actually quite immature at times and often enjoys pranks. One time, he dyed all of Norway’s clothes pink, (blamed it on Denmark) drew on Iceland’s face, (blamed it on Denmark) and hid Denmark’s axe. (Once again, blamed it on Denmark, who actually believed him.)
Denmark always answers his phone, and when it’s one of the other Nordic nations he answers it freakishly fast as if he’d been waiting all day for them to call. He’s up for texting too, especially during meetings and when drunk. No one has showed him how to text pictures from his new phone yet so he doesn’t send out naked pictures of himself when drunk anymore.
Norway almost never answers his phone. Occasionally he’ll pick up for Iceland after three rings, Sweden after four. Finland he makes leave messages because they’re always really awkward (secretly the make him laugh) and Denmark he lets keep leaving messages because they become more panicked with each one (secretly he adores that). His text responses are often cryptic and sent six hours late, just because.
Sweden has customized voice mailbox messages for different people, and he doesn’t answer when he’s out in his workshop or when Finland or Sealand are home. When people dial him as a wrong number they often think they’re speaking with a machine, his voice is so flat, monotone, and forced. No one is allowed to scroll through his phone because he doesn’t want anyone to see the texts he sends out to Finland when he’s drunk. Secretly he’s proud of those texts.
Finland loves to answer the phone in a cheery voice though he finds himself completely thrown when he gets a voice mailbox, leaving rambling messages. He’s not really a big texter because he has a tendency of slipping into using Finnish words when typing, so only really texts Sweden who can understand it. He keeps every text Sweden sends him.
Iceland never answers his phone, only ever texts. He makes everyone wait a while before responding to texts with the exception of his brother, in the hopes that maybe Norway will text him back immediately. So far that plan has yet to work out.
