NTT network min 5GB data contract sim only

Hi,

what is the cheapest option for a NTT network sim card only contract with minimum 5GB data and optionally phone flat. Additional access to NTT public wifi would be the optimum.
Talking about permanent contract not a temporary tourist card or pocket wifi.

Thanks!

probably, only NTTdocomo.

As Ken has suggested - only NTT Docomo offers NTT Docomo plans. Look at their website - but note that contracts can be difficult to get if you don't have a work visa.

Thank you for your input.
There's really no NTT contractors? That's a pity :/
I hope NTT offers sim only contracts.
I always used NTT networks when travelling with tourist data cards and the quality was always superb.
My friend has a Softbank contract and well...not so much.

Also thanks for the tip, I have a working visa :)

NTT OCN DOCOMO all same company

MVNO provider such as Sakura, IIJmio, Bmobile, OCN, LINE, MINEO and quite a few other all use/lease NTT Docomo network SIM . Some of them even offer AU or Softbank network SIM.

You can sign-up with anyone of them based on the plan you want.
You can checkout some of the MVNO provider info here. Go to their respective homepage for more detail plan.

Ah thanks, that's a nice page!

I ended up using DMM. They don't have english support. But you can easily navigate their website and the registration process using Google Translate. They allow you to use foreign credit cards too.

What do you get on Speedtest with DMM? My sources tell me it's not too great.

You can check above site for daily realtime speeds on most MVNO.

I didn't have speed problems so far.
It works acceptable in the middle of the 32st floor toilet of my office.
So that must be a difficult spot.

On the contrary my gf has Softbank and that never works well...

What site should I test the speed?
