Cheap-SIM & Phone Switching Point Activity 2026 — High Reward Plus Lower Monthly Bills

SIM switching is "a high reward + lower monthly bills"

Switching cheap SIMs / phones (MNP) earns you 5,000–15,000 yen via a point site and cuts your monthly bill by a few thousand yen versus major carriers — one of the best cost-performance offers in point activity. You capture "a one-time high-value offer + permanent fixed-cost savings" at once. This article covers the reward, the recommended approach, and MNP cautions. Pair it with the fixed-cost-cuts chapter.

3 benefits of switching

• High-value reward via a point site: 5,000–15,000 yen for MNP / a new contract. A device set can add more.
• Lower monthly bills: a few thousand yen less per month versus major carriers — tens of thousands a year.
• You collect economy points: Rakuten Mobile (Rakuten), povo/UQ (au/Ponta), Y!mobile (PayPay), and others tie into your economy.

Switching steps

1. Compare cashback on point sitesOn Pointnavi, check each SIM offer's value and conditions (activation, usage period).
2. Get an MNP reservation numberIssue an MNP number with your current carrier (keep your number). Lately a one-stop process may make this unnecessary.
3. Apply via the highest siteHave your ID documents ready. It completes online.
4. Reward confirms after activation + a usage periodRewards usually post after activation. Don't cancel during the condition period.

Cautions

• The reward comes after activation/usage: the condition is often activation + X months of use, not just the application.
• MNP transfer-out and contract fees: these are increasingly free, but check for remaining device debt or cancellation fees.
• Signal quality and coverage: cheap SIMs can slow at peak times. Confirm it fits how you use it.
• Short-term cancellation risks blacklisting: repeatedly cancelling right away for rewards can get your contracts refused.
