Our verdict

NTT Docomo runs its own network and sells sim only plans in Japan, each on a rolling monthly term. That suits people who want a short commitment with the option of a much bigger allowance, and docomo mini starts at ¥2,750 a month.

Pros and cons

Pros

  • Plans last 1 month and roll over, so there is no long minimum term to sit through.
  • Sim only pricing starts at ¥2,750 a month on docomo mini, a low way into the range for a line you keep month to month.
  • An eSIM is available, so a new line can be set up without waiting for a card to arrive in the post.
  • Roaming covers 200 countries on fair use terms, so travel abroad does not need a separate line.
  • A multi line discount is available, which lowers the cost of extra lines on the same account.

Cons

  • The plans run in Japan, so they do not serve readers based outside Japan.
  • The unlimited plan costs ¥8,448 a month against an entry price of ¥2,750, so heavy users pay a multiple of the light user bill.
  • Support runs on phone and help centre only, a narrower set of routes than readers may expect from a large operator.
  • Billing is on contract only, while GETESA, Lonestar Cell MTN and yesss! all also list prepaid.

Who it suits

  • People in Japan who want a sim only plan on a rolling monthly term, with an eSIM and a small entry allowance.
  • Households running several lines, since a multi line discount is offered on the account.
  • Travellers leaving Japan, who can keep the same line with roaming across 200 countries.

Who should look elsewhere

  • yesss!, which lists prepaid and a rolling term on contract, rolling and prepaid, if you would rather not sit on a contract basis.
  • GETESA, which offers prepaid billing alongside contract on prepaid and contract, for anyone who wants to top up rather than commit.
  • Anyone living permanently outside Japan, since the plans run in JP only.

Pricing

NTT Docomo lists reference plans at a small allowance, a mid-size allowance and an unlimited option. docomo mini sits at the entry point with ¥2,750 a month, and ahamo covers the middle of the range. The unlimited route is docomo MAX Unlimited at ¥8,448 a month. That is a large step up from the entry price rather than a small one, so light users and heavy users sit in very different bands here. Every reference plan renews on a rolling monthly basis, so the rate at renewal matches the rate at entry and there is no introductory discount to wait out.

What it does well

These are sim only plans, so the monthly price covers the line rather than a handset. An eSIM is supported, so a new line can be set up without waiting for a card in the post. Hotspot sharing is included, so the same connection can serve a laptop or tablet when a fixed line is not to hand. A multi line discount is offered, which lowers the cost of the extra lines on an account. Roaming reaches 200 countries, so a trip away from home is covered by the same plan.

Where it sits among rivals

Entry price is the weak spot. On price from, NTT Docomo sits at 221 out of 258 brands compared, which places it well down the field. The unlimited ranking is friendlier, at 166 out of 173 brands. Overall the brand scores 8.6, with the offer part at 9 and the cost part at 8.2. The practical read is that the strength sits at the top of the range rather than the entry point, so a buyer shopping purely on the cheapest headline number will find cheaper options elsewhere.

Frequently asked questions

What is the cheapest NTT Docomo plan?+

The cheapest listed option is docomo mini at ¥2,750 a month. It is a sim only plan, so the price covers the line rather than a handset, and the data allowance on this tier is small. The plan renews on a rolling monthly basis, so the same figure applies at renewal as at sign-up.

How much does the unlimited data plan cost?+

docomo MAX Unlimited is priced at ¥8,448 a month. That sits at the top end of the NTT Docomo range and runs at a multiple of the entry price, so it is a deliberate step up rather than a default choice. It is sold on the same rolling monthly basis as the smaller plans, with no long minimum term attached.

Is it a sim only plan and can I get an eSIM?+

Yes on both counts. NTT Docomo sells sim only plans, so no handset is bundled with the monthly price, and an eSIM is supported for anyone who wants to start a line without a physical card. Sim only is the standard across this range, which keeps the monthly figure as the real cost of the line.

How long is the contract?+

Plans last 1 month and roll over, and billing is set up on a contract basis. So the line continues on its own each cycle instead of tying you into a long minimum period. For a household whose data use rises and falls, that short term makes it easier to move between the smaller allowance and the unlimited plan without serving notice on a long agreement.

Can I use NTT Docomo outside Japan?+

The plans run in JP and roaming covers 200 countries. Travellers heading out of Japan can keep the same line, though roaming is on fair use terms rather than unlimited abroad. Anyone living permanently outside Japan should look elsewhere, because the plans are sold for use in Japan.

Can I share my data with a laptop or tablet?+

Hotspot sharing is supported on these plans, so the phone connection can be shared with other devices when a fixed line is not available. It is a standard inclusion rather than an add-on, so nothing extra is added to the monthly price. That makes the small entry allowance easier to stretch across more than one gadget.

Is there a discount for running several lines?+

A multi line discount is offered for customers running several lines on the same account. That makes the additional SIMs cheaper than paying for each at the full monthly rate, which suits a family or a small business on a single bill. The discount sits on top of whichever plan each individual line uses.

How do I get help from support?+

Support runs on phone and help centre. Phone is the quickest route for anything urgent, and the help centre handles written questions for anyone who would rather not call. Both sit with the network operator, so billing and coverage questions go to the same place rather than being passed around.
