Daily / total data plans
- After the high-speed data allowance is used, speeds will be reduced to up to 128 Kbps, which can still support basic text messaging.
- Mobile hotspot sharing is supported. Connection speed and stability after sharing depend on the number of connected devices, phone performance and the local network environment; network quality on other devices cannot be guaranteed. For a more stable experience, we recommend using a separate data plan for each device.
Plan validity is calculated according to the provider’s rules, either in 24-hour periods after activation or by calendar day in a specified time zone.
Unlimited plans
- Total data is unlimited during the plan’s validity period and may be used for video meetings, streaming, social messaging and online gaming.
- Mobile hotspot sharing is supported. Connection speed and stability after sharing depend on the number of connected devices, phone performance and the local network environment; network quality on other devices cannot be guaranteed. For a more stable experience, we recommend using a separate data plan for each device.
- Actual connection speed, 5G/4G availability and signal quality remain subject to location, network coverage, peak periods, device specifications and the carrier’s network-management policies.
