I understand that you need to take a unlocked phone to Japan and get a SIM. It seems these are mainly for data useage (internet, email) and if you want phone/text useage, there may be a couple of SIM options available for both phone and data? We want a SIM that does both, so can anyone advise on this please. Also, I read that the SIM thing applies to tablets equally, so do they have to be unlocked and can you use the same SIM (data & voice) for both? We have a lenovo tablet and iphone.
Any help much appreciated. Many Thanks
