The push two talking service that the S! simultaneous talking (I obtain it and do it!simultaneous talking) is provided by SoftBank 3G of SoftBank Mobile. The old name "circle talking."
By the point of the transceiver, up to 11 people can participate in a conversation. An application for "S! friend situation" (210 yen including a monthly basis tax) is necessary for the use. The charge for a call is demanded for a packet communication fee, but an application of the packet flat-rate service is possible. Because it was sound packet transmission, I was able to use it at the time of the Great East Japan Earthquake outbreak at a connection rate at the same level as an email. On September 30, 2011, I give a service and am finished [1].

In this item, I explain 900MHz zone service of SoftBank. Please see "a platinum band" about the overall service around the 800MHz zone about the frequency band around the 800MHz zone in "an 800MHz zone".
In the 2.1GHz obi which SoftBank uses in SoftBank 3G and SoftBank 4G LTE and the 1.5GHz zone, going straight characteristics of the electric wave are stronger than an 800MHz Zone used with NTT DOCOMO and au. Therefore the electric wave situation in a building shadow or the mountains is bad. It is the communication service using the 900MHz obi which an electric wave turns around, and is easy to be crowded to improve this.
A lot of whom "an area is small" complaints, "I was easy to cut communication" were put to SoftBank, and the first place of the reason to cancel service included electric wave product poor quality of the company [1]. However, I anticipate that these electric wave situation is improved by the frequency acquisition of the 900MHz zone and announce, "it is docomo providing a platinum band than before and au and electric wave quality of the same class degree".
After a service start of July, 2012, in the place that became able to use the communication of the 900MHz zone, an offer range spreads out with progress of area maintenance such as a base station or the equipment installation [2].
According to the schedule that SoftBank Mobile (current SoftBank) announced, the service area starts at the time of a start of July 25, 2012 in the base station of several hundred stations. Is spread sequentially afterward, and build more it in approximately 41,000 stations by the end of population cover rate 90%, 2016 in 15,600 stations (22.2% of population cover rates), 2014 at several thousand stations, the end of 2012 before 2012, and plan it when do a population cover rate to 99.9% [3]; [4] [5].
5MHz width *2 that is available than July 25, 2012 provides data communication and a call by the HSPA+ (outbound 21Mbps, upbound 5.7Mbps) [6], and high speed communication by the HSPA+ is available to the third generation models of iPad with the platinum band support model as of March, 2012 [7]. In addition, about 10MHz width *2 of the remainder, it is a plan to provide LTE communication service from summer of 2014 that this becomes able to take advantage of.
A support model to mention later to use platinum band service is necessary. If it is a support model, the change of a 2.1GHz zone and the 900MHz zone is automatically carried out on the terminal side, and there is the merit that an electric wave improves if service and the rate available use a correspondence terminal for the user for equivalence.
In addition, because an electric wave obi of existing 2.1GHz increases a band of 900MHz, according to the announcement of SoftBank, anticipating it is relaxed puts up the congestion of the 2.1GHz Zone [8], and an offer starts FDD-LTE service (SoftBank 4G LTE) using 5MHz width *2 of the 2.1GHz Zone that it was in this way possible for in a line room from September 21, 2012 [9]; [10].

I it about a name
The 800MHz zone was given Japan mobile communication and Daini Denden (it merges later in those days together current KDDI) of the chief editor with a license in the frequency for the cell-phone in Japan Toyota Motor Corporation where I entered by NTT Co. (current NTT) which started in 1979, communication liberalization of 1985. On the other hand, in the 1.5GHz Zone that was reported when you should free him for cell-phone use for the purpose of competition promotion in a council for electric wave of 1990, JR pro-Japan Telecom and Nissan Motor are entries. I started service as digital phone, Tu-Ka Phone KANSAI, digital on the same wavelength, Tu-Ka Cellular Tokyo, Tokai (at the time of each). Of these, a digital phone and the digital understanding each other perfectly are complicated and become J-Phone and reach present SoftBank via Vodafone, SoftBank Mobile, but SoftBank does not possess an 800MHz Zone from such a process.
The electric wave has a long outreach so that frequency is low. When SoftBank Mobile which did not last was a process of the frequency reorganization of the 800MHz zone, and only 1.5GHz and a 2.1GHz obi appealed saying it "is unfair I broke only the company, and not to have a hope", a meaning that utility value was high said an 800MHz Zone with "a gold frequency band". SoftBank Mobile (current SoftBank) which aimed at the acquisition ahead of a 700/900MHz Zone license grant of 2012 came to refer a 700-900MHz obi to "a platinum band" afterwards when I insisted, "you should assign it equally with NTT DOCOMO, KDDI". And, in February, 2012, allocation to SoftBank Mobile of the 900MHz zone is decided. After a press release of March 1, the following day, I came to call myself "a platinum electric wave" this time. However, it became the notation called "a platinum band" again at the new model presentation of May 29, the same year, and "the platinum electric wave" was not used. "Only the platinum band" is used now. In addition, the company performs a trademark application of "the platinum LTE" in the Patent Office in June, 2013 and may call planned LTE to start use from the frequency that SoftBank has in a 900MHz Zone with "platinum LTE".
But it is confirmed to name the LTE service of the 1.7GHz zone of EMOBILE Ltd. (current Y!mobile) which purchases eAccess Ltd. (including WILLCOM OKINAWA, Inc. of the current Y mobile, subsidiary), and started "a platinum band of the LTE" with some promotion documents, and the definition of the platinum band becomes vague.
Support model
Because the 900MHz obi which the platinum band uses is a frequency band used for cell-phones except the North America of the world as an international band switched by GSM, but is not used any place other than SoftBank Mobile in Japan;, in the original correspondence terminal, leading a global terminal. In addition, terminal made in Apple which has been released on (March 1, 2012) at the point of service announcement of the platinum band and product made in HTC terminal after X04HT, PANTONE 4 (105SH) terminal made in Sharp are support models [11].
In addition, the sound terminal (I include a smartphone) after the summer of 2012 model supports all models. But MVNO (there is part of non-compliant terminal in a released model from Y!mobile) of the WILLCOM (present.of SoftBank
It is the list of models announced that the following supports a platinum belt at the time of service in of July 25, 2012 or I am going to cope [12].

In addition, the use enables a platinum band in form of the SoftBank roaming, and 302HW which it released in Y mobile lets the platinum band cope even with others, the EMOBILE 4G-S terminal of the eAccess Ltd. times and the terminal for the "telephone service" (type 1) of the Y!mobile brand of the succession contract at all terminals. In addition, 302HW which is a type 2 (is going to go off the air on January 31, 2018) terminal becomes the form of the SoftBank Mobile roaming, but the call that used a platinum band area is enabled.

As for this article, update is required. The information of this article is not updated for a long time, and old information is placed. Let an article reflect new information in the case of editing. After reflection, please remove this tag. (March, 2015)
Outbound up to 110Mbps, high-speed communication of upbound up to 10Mbps are selling, and it is the first commercial data communication service that adopted TD-LTE and AXGP with the compatibility with value of standard. To 76Mbps outbound in the terminal provided in service in of February 24, 2012 came to support it, but exceed indoor descent up to 75Mbps of Xi which NTT DOCOMO provides 1Mbps in value of standard, and go down it, and declare industry fastest を of the transmission rate.
The service area is limited to the extremely small range to become the construction from zero, but aims at population cover rate 99% in ordinance-designated cities of the whole country at the end of March, 2013. When I develop a base station of AXGP, I exchange it with an omni antenna new machine of the PHS common use using existing Willcom base station. [1]
I include a word 4G, but am not close 4G standard to satisfy a demand of IMT-Advanced which ITU prescribes [1].
When SoftBank Mobile becomes the MVNO of AXGP, there is the biggest characteristic in "SoftBank 4G" of outbound up to 110Mbps and "ULTRA WiFi 4G" which goes down it, and put "ULTRA SPEED "of up to 42Mbps together. Because the ULTRA SPEED area of the company network is available if it is a contract and the terminal corresponding to this, I can try connection in wide ULTRA SPEED of the service area in the AXGP outside.
I start service for smartphones on October 10, 2012 (as for the correspondence first issue machine SoftBank 201HW). The outbound maximum speed for smartphones became 76Mbps, but, for a reason that battery consumption was intense, I went down and did not seem to do it with fastest 110Mbps. In addition, テザリング became the start from December 15, 2012.
On October 19, 2012, I started the service with the data terminal of outbound fastest 110Mbps.
The terminal which the LTE area of eAccess Ltd. can cover is released for the purpose of the supplement of the AXGP area from August 9, 2013.
I added it to the AXGP area from December, 2013, and the terminal which the SoftBank 4G LTE area could cover was released as "Hybrid 4G LTE".

In addition, the smartphone will choose it among a plan for SoftBank 4G LTE.
After October, 2012, as for the case beyond 7GB, it is set a limit transmission and reception quantity of communication per month together by 128kbps. I can cancel traffic calming by paying an additional charge of 2,500 yen every 2GB when it is set a limit. In addition, a case, transmission rate beyond 1GB may be limited quantity of packet transmission of most recent three days. I cannot cancel the latter traffic calming by an additional charge. In addition, this regulation is the same as a communication limit of Xi, PREMIUM 4G which NTT DOCOMO provides and the au 4G LTE that KDDI provides.
Correspondence terminal
In the following terminals, most of correspond to ULTRA SPEED except Hybrid 4G terminal for LTE. I refer to the following identification marks for other special mention services.
The service for public using AXGP which Wireless City Planning provides is in a condition only of SoftBank Mobile and TOKAI communications two as of February, 2013, and the offer by Wireless City Planning oneself is not planned, too (as for the Y mobile an offer for the sublet from SoftBank Mobile).
In addition, it is demanded that I fix the condition that MVNO except SoftBank Mobile is easy to enter because AXGP using a band for BWA and entry promotion of the MVNO become the condition of the license.
An offer of SoftBank Air using the router (Air terminal) to install in the homes begins in December, 2014 using AXGP (as for the business main constituent SoftBank BB → SoftBank Mobile).

By service offered in the SoftBank 4G LTE that SoftBank provides with SoftBank brand, I add it to an LTE network of SoftBank (the band which SoftBank Mobile Co., Ltd. before merging Y mobile Co., Ltd. exactly provides), and, with the double LTE (double L tea E), an LTE network of the former Y mobile (old eAccess Ltd.) is service becoming available.

Summary
It was started for the purpose of congestion cancellation of LTE Band 1 (2.1GHz zone) used in SoftBank 4G LTE on March 21, 2013 [1].
Because it comes true by adding identifier signal (PLMN=440-20) of SoftBank Mobile to electric wave (PLMN=440-00) which a base station of EMOBILE Ltd. fires, if it is a model corresponding to LTE Band 3 (1,800MHz zone), I propose it, and it is unnecessary and is available, and the rate does not occur separately, too.
In addition, according to the announcement of SoftBank Mobile, it is designed so that it is connected to the line that it is not crowded with precedence and is that it becomes hard to occur to have said that it is different in a congestion degree every line.
I speed up "double LTE" more on September 20, 2013, and each becomes outbound up to 75Mbps, and it is the double speed double LTE that ultraspeed communication is possible.
The LTE service by the 900MHz zone of SoftBank Mobile is started in July, 2014, and it is "the triple LTE" that added this 900MHz Zone to a 2GHz zone and the 1,800MHz zone, but does not perform the special announcement.
Support model
The service start original correspondence terminal was a model of the apple product for LTE, and a support model increased the Hybrid 4G terminal (it supports AXGP) of Android for LTE later, too. In addition, I can use this service at the SIM-free terminals if it is the model supporting 1 and 3 (8 increases in the case of triple LTE) of the LTE band number.
By the way, EM01L of the Y mobile supports a double LTE net, too (the terminal specifications top supports triple LTE). In addition, it becomes the complicated form called MVMO handling (so-called sublet) from SoftBank Mobile while using some company line.
