Recommended plan by trip type
Frequently asked questions
3 GB enough for a week abroad?
3 GB is enough if you use maps sparingly, stick to WhatsApp, and have Wi-Fi at your accommodation. If you plan to stream videos or use social media heavily, go for at least 5–8 GB.
Does downloading maps use data?
Downloading offline maps uses data once (typically 200–500 MB for a city). After that, navigation uses almost no data. Highly recommended for long trips.
Will I run out of data if I forget to limit usage?
Most BleSIM plans switch to limited speed when the data allowance runs out instead of charging extra. You can always top up or switch to a new plan digitally.
Does my hotel/hostel Wi-Fi affect how much I need?
Yes significantly. If you can rely on good Wi-Fi at night for streaming and video calls, you can reduce your mobile data plan by 30–50%.
