I am seeking for a prepaid or rent a sim card with voice & data plan or only data plan, i.e. short-term service without contract and no rental phone attached.
From what I understood; Docomo, Softbank, EMOBILE & bmobile do not offer short-term data packages to non-residents without an Alien Registration Card.
Any experciences / recommendations on this subject?
