FAQ
Are there voice SIM plans available under ¥1,000/month?
Occasionally yes, particularly during promotional periods. These plans typically offer limited data (around 1GB) and charge per-minute rates for calls. Comparing against plans in the ¥1,000–¥1,500 range with a call add-on may yield better overall value.
What is the cheapest plan for under 1GB of monthly data?
Data-only plans start around ¥500/month from several carriers. Exact prices change frequently — check SimFinder's live comparison for current pricing. Note that data-only SIMs do not include a phone number.
Are there initial setup fees when switching to a budget SIM?
Most budget carriers charge an initial registration fee of approximately ¥3,300 and sometimes a SIM issuance fee of ¥220–¥440. Many waive these during campaigns. Factor in the initial cost when calculating break-even time.
