FAQ
What do I need to use 5G on a budget SIM?
You need a 5G-capable device (SIM-unlocked or SIM-free) and a 5G-enabled plan. Check your phone's specs page to confirm 5G support. Also verify that the carrier's 5G network covers your area using the coverage map on their official website.
Do 5G plans cost more than 4G plans on budget carriers?
Most budget carriers in Japan offer 5G access at the same price as their 4G plans. If you own a 5G device, there is typically no additional cost to use 5G. A small number of carriers require a paid add-on — check plan details before signing up.
Which carrier network do budget 5G SIMs use?
Budget carriers (MVNOs) lease network capacity from one of the three major carriers: NTT Docomo, au (KDDI), or SoftBank. A 5G MVNO plan gives you access to whichever major carrier's 5G network they use. Coverage quality varies by region, so compare coverage maps for your area.
