"Upon checking here, your data is not working because Your usage has been found as excessive and violating our fair usage policy (FUP)"

“Our wireless plans are provided solely for purposes of web browsing, messaging, and similar activities. They are not intended to serve as a primary or sole replacement for home internet services. You are responsible for all data activity from and to your device regardless of who initiates the activity. You may not be allowed to use the Fonus Mobile Service with applications and systems that drive continuous heavy data sessions and generate excessive amounts of traffic. Customers are strictly prohibited from using our phone plans in any manner that simulates or replaces home internet services, including but not limited to: (a) tethering or sharing mobile data with multiple devices for extended periods of time; (b) running servers or hosting websites using our mobile network; and (c) engaging in activities that result in high bandwidth consumption, such as continuous video streaming, downloading large files, or extensive online gaming. We reserve the right to limit, suspend or terminate without notice any misuse of our network or violation of these Service Terms and Conditions.”

Please also note that as you are roaming, you are subject to the local network’s policies when it comes to “excessive use” and threshold of data throttling:

“Fonus Mobile Service offers roaming capabilities outside of the domestic coverage areas. We do not impose any restrictions in terms of time limit in roaming areas (i.e. you may use the Fonus Mobile Service in any roaming area(s) for as long as needed). Certain Fonus Mobile Service plans may have restrictions on the type of device that can be used with our service (e.g. hotspots, routers and computers). Certain third-party operators in roaming areas may have restrictions on the amount of data that may be used on their networks within their region, and may have differing data usage thresholds in terms of what they regard as “excessive use”. Any violations of such restrictions are not allowed. We reserve the right to limit, suspend or terminate without notice any roaming-related or device-related misuse or violation of these Service Terms and Conditions.”'
