お客さまの声
They were very helpful, from initial setup to data transfer.
thank you very much.
If you switch from a major carrier to J:COM Mobile,
I saved about 10,000 yen.
It's very reasonable and the line speed is one of the faster among low-cost SIMs.
I feel that there are many benefits to switching over.
