What the title says
I saw a lot of people in this subreddit recommend Ahamo. Can I get Ahamo right after getting my residence card in the airport or do I need to go to the city hall (which isn't tokyo) to register my address and then I would be able to get the card?
If its the latter case (I can't get Ahamo at the airport) What is a cheap (prepaid or not) sim to get until I change it to Ahamo? Esims are also an option.
