Extend Acceptable/Fair Use Policy

This Acceptable / Fair Use Policy (“AFUP”) governs your use of Tango Networks Communications Service(s). By activating, using, or paying for any Tango Networks Communications Service(s), or a third-party service based on Tango Networks’ Communications Service(s), you are accepting and agreeing to be bound by this Policy Agreement.

The Communications Service(s) is a shared resource which is managed for the benefit of all customers. You may use the Communications Service(s) for mobile voice, messaging, and data access in accordance with the allowances set forth in your subscription plan. Tango Networks reserves the right to deny or restrict your Communications Service(s) if in Tango Networks’ sole discretion your usage:

1. Compromises network security or capacity, degrades network performance, uses malicious software or “malware”, hinders other customers’ access to the network, or otherwise adversely impacts network service levels or legitimate data flows;
2. Uses applications which consume unreasonable amounts of available network capacity;
3. Uses applications which are designed for unattended use, automatic data feeds, automated machine-to-machine connections, or applications that are used in a way that degrades network capacity or functionality;
4. The Communications Services may not be used for Application-to-Person (“A2P”) messaging, including but not limited to bulk messaging, automated notifications, one-time passwords (OTPs), marketing messages, or transactional messaging, unless expressly authorized in writing by Tango Networks.
5. Misuses the Service, including “spamming” or sending abusive, unsolicited, or other mass automated communications;
6. Accesses the accounts of others without authority;
7. Resells the Service, either alone or as part of any other good or service;
8. Operates as a forwarding service
9. Tampers with, reprograms, alters, or otherwise modifies the eSIM/SIM or Device to circumvent any of our policies or violate anyone’s intellectual property rights;
10. Causes harm or adversely affects us, the network, our customers, employees, business, or any other person;
11. Conflicts with applicable law;
12. Attempts or assists or facilitates anyone else in any of the above activities.

Smartphone Subscription Plan Usage

• Usage in any one Home Away Country is limited to 90-days in any 365-day period.
• All plans are for use only in conjunction with end user mobile devices such as phones, smartphones, and tablets (subject to device compatibility restrictions)

Fixed Wireless Device Subscription Plan Usage

• Usage is limited to Home Countries only.
• All plans are for use in conjunction with fixed wireless devices such as deskphones, Analog Telephone Adapters (ATAs), and hotspots.

Data Usage

You agree that the term ‘unlimited data’ when used to describe a Tango Networks subscription plan indicates that the amount of data you can consume is not subject to a fixed data cap; however, the speed at which data may be consumed is not guaranteed and may be limited.

Data Speeds; 4G / 5G Availability

Data speeds may be limited by:

• Attached Mobile Network: Tango Networks utilizes the Radio Access Networks (RANs) of partner mobile network operators in each country in which we provide service. The data speeds you experience will depend on the partner mobile network operator you are attached to. See our Global Availability web page for data speed information per country/operator.

In addition to the attached mobile network, actual data performance may also be affected by factors including, but not limited to, device capability, radio technology, signal strength, location, network congestion, service configuration, roaming status, Tango Networks’ core network and interconnections, and applicable network management practices.

References to 4G, LTE, or 5G describe access to those radio technologies where available and supported and do not constitute a guarantee of minimum data rates, throughput, latency, or quality of service. Tango Networks does not warrant that users will achieve maximum theoretical speeds or performance levels advertised by any underlying mobile network operator.

• Network Congestion: The cell tower you are attached to and/or the data networks it relies on may become congested and limit your data speed.

• Fair Use: Tango Networks reserves the right to manage data usage, including limiting speeds, where usage materially impacts network performance, violates this AFUP, or adversely affects other users.

WiFi Calling

WiFi Calling allows you to make and receive calls over a WiFi network when a cellular signal is weak or unavailable, subject to device compatibility and network conditions. WiFi calling may be available in certain locations and environments and is subject to technical, regulatory, and network-operator limitations. Availability is not guaranteed in all countries or locations. Where available, WiFi Calling does not itself incur roaming charges; however, outbound calls placed using WiFi Calling will be charged applicable call termination fees as if the call were placed from the user’s Home Country (for example, a call to Country X will be charged the same whether placed from the Home Country or via Wi-Fi Calling while located in Country X). TTY devices are not supported with WiFi Calling due to technical limitations.

VoLTE (Voice over LTE)

VoLTE (Voice over LTE) enables voice calls to be carried over LTE data networks to improve call setup times and voice quality where supported. VoLTE availability depends on multiple factors, including device capability, software configuration, mobile network operator support, roaming agreements, and network conditions. VoLTE is not available in all countries, on all networks, or for all devices, and may not function while roaming or in areas with limited LTE coverage. Tango Networks makes no warranty or guarantee that VoLTE will be available, uninterrupted, or supported in any particular location or on any particular network. Where VoLTE is unavailable, voice calls may fall back to alternative voice technologies or may not be supported, depending on network conditions and device configuration.

Emergency Calling

When placing a call to an emergency number (e.g. 911, 112, 999, etc.), your device will either automatically attempt to use a cellular connection or prompt you to make a selection between cellular and WiFi Calling. If prompted, you should choose to use a cellular connection. This maximizes the chance your emergency call will be routed to the Public Safety Answering Point (PSAP) closest to your location, both domestically and while roaming internationally.  If no cellular signal is available or you choose to use WiFi Calling, your device will place the emergency call via WiFi Calling if connected. Emergency calls placed via WiFi Calling are only supported in your home country. All WiFi Calling calls, including those to emergency numbers, will drop if you lose internet connectivity. 

Emergency calls will be routed to a PSAP based on automatic location information provided by your device. If such information is unavailable, your call will be routed to a default PSAP in which case you must provide the PSAP operator with your current location. Emergency services may be delayed if automatic location information is not available. By accepting this agreement, you acknowledge and agree that Tango Networks may use automatic location information as your temporarily updated emergency calling address.
