SIM for calls only

Hi everybody,
I'm going to Japan next week for 14 nights. My hotel covered with wifi; fair enough for me.

Just need Voice-Only sim for my unlocked iPhone 5S to be in touch with my family at home. I do appreciate your advice in below 2 questions:

1. Where is best place / Co. I can rent economic sim? (expected to call my family approx. 5min./day).

2. Do you think I can easily get nano sim (for my iPhone 5s) or better I take old phone with micro or normal sim?

thanks a lot

I would use Skype while in the hotel room. Or will you need to call them at other times of the day?

If its for regular calls just to check in then I would also recommend using skype or other voip service for your calls as it will be far cheaper than international calls via rental or prepaid sim.

But if you do need to be in contact while on the road then I would recommend getting either a softbank prepaid or rental sim to cover your calling.

Yes, you can easily find nano sim rentals, however you may have more selection if you also look for normal sims. Check here for some of the services available at Narita:
