FAQ
Can I use a data-only SIM in an iPad or tablet?
Yes, for SIM-slot-equipped tablets. iPad Wi-Fi + Cellular models have a SIM slot; Android tablets vary. Check whether your device uses nano-SIM, micro-SIM, or eSIM and select the appropriate SIM type. Many recent iPads also support eSIM.
Can I make calls on a data-only SIM?
Traditional phone number-based calls are not possible. However, VoIP apps such as LINE, WhatsApp, Skype, and FaceTime all work over data. Note that emergency calls (110, 119) cannot be made from data-only SIMs.
How much cheaper is a data-only SIM compared to a voice SIM?
For the same data allowance, data-only SIMs are typically ¥200–¥500 cheaper per month. For example, a 3GB voice SIM might cost ¥1,078/month while the equivalent data-only SIM costs around ¥550. If you have no need for voice calls, data-only is the most cost-efficient choice.
