The quick answer: which one are you?
Conclusions first. If in doubt, check your data usage over the last three months โ that decides it.
| Your profile | Pick | Why |
|---|---|---|
| 30 GB+/month, heavy tethering | Rakuten Mobile | The only unlimited plan at this price |
| 20โ30 GB, signal first | ahamo | Docomo network peace of mind |
| Heavy caller (30+ min/day) | Rakuten Mobile | Completely free via Rakuten Link |
| 3+ overseas trips a year | ahamo | Your 30 GB works abroad as-is |
| Heavy Rakuten Ichiba shopper | Rakuten Mobile | Boosts your SPU point multiplier |
Plans side by side
Don't compare sticker prices alone โ include calling options and what happens in low-usage months.
- Usage varies month to month? Rakuten's tiered pricing wastes nothing
- Consistently 20โ30 GB? The flat-rate ahamo costs about the same
| Item | Rakuten Mobile | ahamo |
|---|---|---|
| Monthly (tax incl.) | ยฅ1,078โ3,278 (tiered) | ยฅ2,970 (flat) |
| Data | Unlimited | 30 GB (110 GB with Omori, ยฅ4,950) |
| Domestic calls | Free via Rakuten Link | 5-min calls included (then ยฅ22/30s) |
| Network | Rakuten + partner roaming | Docomo |
| Admin/cancel fees | None | None |
| Light months | Auto-drops to ยฅ1,078 under 3 GB | Stays ยฅ2,970 |
Measured speeds: same place, same hour
We carried both SIMs and measured simultaneously. Both are plenty above ground; basements and big buildings showed a gap. (Template figures โ replace with your own.)
- Above ground, the difference is barely noticeable
- Deep indoors and underground, ahamo's Docomo network stays ahead
- Rakuten keeps improving with its platinum-band rollout โ check your own area
| Location | Rakuten Mobile | ahamo |
|---|---|---|
| Home (residential) | 48 Mbps | 52 Mbps |
| Station (lunch hour) | 40 Mbps | 45 Mbps |
| Subway platform | 8 Mbps | 25 Mbps |
| Large shopping complex | 12 Mbps | 30 Mbps |
Calls, overseas use and points
- Calls: Rakuten is completely free via the Rakuten Link app; ahamo bundles 5-minute calls, then ยฅ22/30s
- Call quality: Rakuten Link is VoIP, so in weak-signal spots ahamo's native calling wins
- Overseas: ahamo's 30 GB works in 91 countries/regions as-is; Rakuten includes 2 GB of free roaming monthly (see our overseas-use note)
- Points: a Rakuten Mobile contract raises your Rakuten Ichiba SPU multiplier โ ecosystem users close the price gap further
Switching (MNP): steps and gotchas
Both sign-ups are fully online, and one-stop MNP means no reservation number. Here's what we actually did.
- Prepare an ID document and a credit card (or bank account)
- If your current carrier supports one-stop MNP, just choose to keep your number during sign-up
- eSIM activates same-day on both (Rakuten claims as fast as 3 minutes)
- Switching late in the month? Check pro-rating โ ahamo bills the full month
- Still torn? Run both lines for a month (zero cancellation fees on both)
Mga Kalamangan (nagustuhan namin)
- Rakuten: ยฅ3,278 unlimited is unmatched; light months get cheaper automatically
- Rakuten: calls drop to ยฅ0 via Rakuten Link
- ahamo: Docomo network stays solid underground and indoors
- ahamo: 30 GB of free international roaming
- Both: no admin or cancellation fees โ switching is low-risk
Mga Kahinaan (dapat bantayan)
- Rakuten: speed dips in basements and large buildings
- Rakuten: Link call quality depends on signal
- ahamo: capped at 30 GB (110 GB with Omori) โ no unlimited
- ahamo: online-only support, no voicemail

Mga madalas itanong
Which is cheaper, Rakuten Mobile or ahamo?
Under 3 GB/month, Rakuten Mobile (ยฅ1,078) wins by a mile. In the 20โ30 GB band it's roughly even (ยฅ2,178โ3,278 vs ยฅ2,970). Above 30 GB, Rakuten's unlimited tier is the only option.
Which has better coverage?
In our tests the two felt identical above ground, but ahamo's Docomo network was consistently stronger in subways and large buildings. Rakuten is improving with its platinum band โ test in your own area if possible.
Can I try both at once?
Yes. Neither charges sign-up nor cancellation fees, so running both lines for a month and keeping the winner is the lowest-risk approach โ it's exactly how we tested.
Which is better for heavy callers?
Rakuten Mobile, since Rakuten Link makes domestic calls completely free. If rock-solid voice quality matters more than cost, ahamo's native 5-minute calling is the safer bet.
Which is better overseas?
ahamo for frequent travelers โ its full 30 GB works in 91 countries and regions at no extra cost. Rakuten Mobile includes 2 GB of free roaming per month, enough for light use.
