Payments and Account Balance

The availability of Services depends upon your payment in advance of all Charges when they are due. If you fail to make payments when due, the Services will be suspended and/or canceled.

Information on Your Device

Your Device and SIM card may contain sensitive personal information (such as financial, healthcare, government-issued information and identification numbers, credit card numbers, pictures, videos) that you may wish to protect and not disclose to others. Sakura Mobile is not responsible for any of the information on your Device. You must remove any sensitive personal information from your Device before you return, exchange, recycle, or otherwise give up control of your Device.

You further agree to cooperate in the investigation of fraud or theft and to provide us with such requested information and documentation (including any proof of loss and police reports) as we may reasonably request.

Availability of Service and Coverage

Services may be interrupted, delayed, or otherwise limited for a variety of reasons, including environmental conditions, unavailability of radio frequency channels, system capacity and constraints, priority access by National Security and Emergency Preparedness personnel in the event of a disaster or emergency, coordination with other systems, equipment modifications and repairs, and problems with the facilities of interconnecting carriers. We do not guarantee the availability of the wireless network or any Wireless Services. You will not have access to our network outside of our coverage areas. Coverage maps, available from us, show a high-level approximation of wireless coverage and there are gaps in coverage not shown by this approximation; actual coverage may vary and be affected by terrain, weather, foliage, buildings, signal strength, high-usage periods, customer equipment and other factors. We do not guarantee coverage and the maps supplied by the network carriers Sakura Mobile uses do not show actual network coverage or performance.

Voice Services

Voice Services are provided primarily for live dialog between two individuals. If Sakura Mobile determines that you are using our Voice Services for other than live dialog between two individuals, we may terminate your Service.

SMS Services

We automatically applies the 「Reject dangerous SMS」 function to all products with SMS function (Voice+Data SIM & Data Only SIM). 「Reject dangerous SMS」 is a protection that judges and executes by Docomo to rejection SMS from numbers with suspicion of phishing activities. 「Reject dangerous SMS」 function has the following condition. (a) Apply to both Voice+Data SIM card & Data Only SIM card automatically on the contract starting date. (b) The 「Reject dangerous SMS」 function can not be applied simultaneously with 「Individual number reception」 & 「Reject all SMS」 function. If you have applied for either 「Individual number reception」 or 「Reject all SMS」 function, then 「Reject dangerous SMS」 will automatically be canceled.

Airtime Usage

If your Service includes measured voice usage, your airtime is charged in 30-second increments, and actual usage is rounded up to the next 30-second increment at the end of each call. We charge a 30-second of airtime usage for every fraction of the 30-second of airtime used. Airtime begins for outgoing calls when you press SEND (or similar key) and for incoming calls when a signal connection from the caller is established with our facilities. Airtime ends after you press END (or similar key), but not until the disconnect signal is received by our facilities and confirmed. All outgoing calls for which we receive answer supervision or which have at least 30 seconds of airtime, including ring time, will incur a minimum of 30-second airtime charge. Answer supervision is generally received when a call is answered; however, answer supervision may also be generated by voicemail systems, private branch exchanges, and interexchange switching equipment. Airtime may include time for us to recognize that only one party has disconnected from the call, time to clear the channels in use, and ring time. Airtime may also occur from other uses of our facilities, including voicemail deposits and retrievals, and call transfers. Calls that begin in one rate period and end in another rate period may be charged during the period in which the call began. For overseas usage of Sakura Mobile products, airtime usage will be charged in full-minute increments.

Data Services – Permitted Uses

Sakura Mobile provides wireless data and messaging Services, including, but not limited to, features that may be used with data services and wireless content and applications (“Data Services”). Our Data Services are intended to be used for the following permitted activities: (a) web browsing; (b) email; (c) internet access; (d) uploading and downloading ordinary applications and content to and from the Internet; and (e) using applications and content without excessively contributing to network congestion. You agree that Sakura Mobile may engage in any reasonable network management practice and that you will use Sakura Mobile's Data Services only for these permitted activities.

Data Services – Applications and Content

Our Data Services may allow you to access the Internet where you will have access to text, pictures, video, games, graphics, music, email, applications, sound, and other materials primarily from third party content providers unaffiliated with Sakura Mobile (“Data Content”) and where you will have the ability to send, receive and share Data Content. You may also purchase Data Content with your Device from us or from third parties. Sakura Mobile is not a publisher of third party Data Content and is not responsible for any opinions, advice, statements, or other information, services, or goods provided by third parties. Third-party Data Content may among other things be offensive, indecent, violent, pornographic, inappropriate, false and misleading, inaccurate, unreliable, and unsuitable for children and minors – you are solely responsible for any third party Data Content accessed through our Data Services. The accuracy, appropriateness, content, completeness, timeliness, usefulness, security, safety, merchantability, fitness for a particular purpose, transmission, or correct sequencing of any application, information, or downloaded data is not guaranteed or warranted by Sakura Mobile or any content providers or other third party. Neither Sakura Mobile nor its content providers, service providers, or other third parties shall be liable to you for any loss or injury arising out of or caused, in whole or in part, by your use of any information, application or content, or any information, application, or other content acquired through our Data Services. Third-party Data Content may harm your Device and its software, and we are not responsible for any third party Data Content that you download, install, or use with our Data Services.

Data Usage

We measure data usage by the kilobyte or the megabyte or gigabyte, where 1024 kilobytes equals 1 megabyte, and 1024 megabytes equals 1 gigabyte. To determine your data usage, we calculate in full-kilobyte increments, and actual usage is rounded up to the next full kilobyte increment at the end of each data session. Data usage occurs whenever your Device is connected to our network and is engaged in any data transmission. This includes among other things, sending and receiving email, texts, documents, and content; accessing websites; and downloading and using applications and content. Some applications, content, programs, and software that you download or that come pre-loaded on your Device automatically and regularly send and receive data transmissions without any action by you and without your knowledge. For example, applications that provide real-time information and location-based information connect to our network and continuously send and receive updated information. In addition, advertisements or advertiser-related messages or data delivered to your Device, even if delivered to an application, as well as any messages or content initiating a response to an advertisement, will count toward your data usage. Network overhead, software update requests, email notifications, and resend requests caused by network errors can increase data usage. You will be charged for all data usage when your Device is connected to our network, whether you initiate the connection or it runs automatically in the background and whether successful or not.

Rate Plans

Sakura Mobile’s Wireless Service rate plans offer voice calls, SMS, and data service reflected in the contract you signed up for. After your high-speed data access allowance is used (if applicable), your data download speeds will be reduced to a low-speed mode with speeds differing between products for the rest of your billing cycle. For all Sakura Mobile plans, high-speed data access allows download speeds of a maximum of 20 Mbps for compatible 4G LTE devices and 3 Mbps for compatible 4G HSPA+ devices.

Unlimited Data

You agree that “unlimited” means you pay a single monthly flat rate that includes wireless data service regardless of how much data you use in a billing cycle. You further agree that “unlimited” does not mean that you can use Sakura Mobile's wireless data service in any way that you choose or for any prohibited uses and that if you use your unlimited data plan in any manner that is prohibited, Sakura Mobile can limit, interrupt, suspend or cancel your Service. Any unlimited plan we may offer is subject to these Ts&Cs, including the restrictions against prohibited uses and misuse and abuse of our Services and Devices, any reasonable network management practices, and our Acceptable Use Policy. Plans are also subject to network carriers' Fair Usage Policy (FUP), which ensures a stable network for all users by restricting the data transmission of users deemed to be using excessive amounts of data hindering network usage of other users.

Location-Based Services

Sakura Mobile collects information about the approximate location of your Device in relation to our cell towers and the Global Positioning System (“GPS”). We use that information, as well as other usage and performance information also obtained from our network and your Device, to provide you with wireless voice and data services, including services which may be provided by third parties, and to maintain and improve our network and the quality of your wireless experience. We may also use location information to create aggregate data consistent with our Privacy Policy. It is your responsibility to notify users on your account that we may collect and use location information from Devices. Your Device is also capable of using optional content at your request or the request of a user on your account, offered by Sakura Mobile or third parties that make use of your Device location information (“Location-Based Services”). Please review the terms and conditions and Sakura Mobile’s privacy policy for each Location-Based Service to learn how the location information will be used and protected.

Sakura Mobile’s Data Services may not be used with high bandwidth applications, services, and content not optimized to work with Sakura Mobile’s wireless data services and, therefore disproportionately and excessively contribute to network congestion. This includes, but is not limited to, redirecting television signals for viewing on computing devices, web broadcasting, and/or the operation of servers, telemetry devices, or supervisory control and data acquisition devices. You agree not to engage in conduct toward our employees, customers, or others that involves the use of abusive, derogatory, insulting, threatening, vulgar, offensive, or similarly unreasonable language or behavior; engage in conduct that is harmful to, interferes with, damages, or adversely affects our network and infrastructure, property, Services, Devices, operations, customers, reputation, intellectual property rights, or that results in the publication of threatening, offensive or illegal material, or generates spam or other abusive messaging or calling, a security risk, or a violation of privacy; or violate, in any way, these Ts&Cs, the Agreement, or our Policies.
