Birthdays are coming up and my eldest wants a walkie talkie to chat with her sister in the weekend.
But since they are 60km apart during the week I'm thinking of a dedicated PTT device that connects them over the internet (wifi connection).
No smartphone since the youngest isn´t always allowed t have her phone in the dorm room.

So, tips welcome.
