Cheap and connected
A safe smartphone

I like J:COM MOBILE. Although the price is low, the connection is stable.

20s/female
I signed a contract for my child.

By subscribing to J:COM NET's Wi-Fi, I can enjoy the internet and games in the comfort of my home. Also, last month I signed up for a new smartphone for my child, and it's cheap so it's safe for my family budget. I am also considering switching to a carrier line for my family.

40s/Female
I'm glad the data capacity has increased.

The amount of data you can use on your smartphone (GB) has been increased for free starting from February. I'm very happy because I've been able to save on communication usage up until now.

70s/female
Leave the troublesome initial settings to J:COM

I switched my smartphone to J:COM and the charges are now half the price. J:COM came to my house and took care of all the data migration operations.

60s/male
The line is stable and comfortable

I am using my smartphone at J:COM. There are no slow connections during the day or evening, and I am very satisfied with the service.

50s/Male
Music and videos on the go

The great thing about J:COM MOBILE is that you can use J:COM Music and J:COM STREAM from anywhere without incurring communication charges.
