It used to be a handle for consumers to change a mobile carrier because we were forced to purchase a new mobile which can cost about JPY 80,000 (USD 800) for a smartphone.
However, recently, the government requested mobile companies to unlock SIM.
(Hummm, the government finally has done something good for citizens.)
From the latest iPhone 6S and iPad Mini 4, we can request a mobile carrier to unlock SIM if a mobile or tablet is registered for more than 6 months.
Last week, I roamed and I know it costed me unfortune.
I’m planning to unlock my iPad to allow using overseas’ SIM or inexpensive data SIM to save cost for roaming.
