FAQ
Is 3GB enough for daily commuting use?
For typical commute use — checking social media, streaming music, and using maps — 3GB is generally sufficient. Assuming a 30-minute commute each way on weekdays with text-heavy apps, you should stay within the limit. However, if you watch videos every day on the train, consider upgrading to a 5GB plan.
Can I use video streaming services on a 3GB plan?
Yes, services like Netflix and Amazon Prime Video are usable, but you will need to limit on-the-go streaming. Standard quality video gives you roughly 10–12 hours per month. Using the offline download feature to pre-download content over Wi-Fi can significantly reduce your mobile data usage.
Does unused data roll over to the next month on a 3GB plan?
Rollover availability depends on the provider. Many MVNOs such as IIJmio offer rollover features. Choosing a plan with rollover means unused data from quieter months carries forward, improving overall value. Check the rollover column in SimFinder's comparison table for up-to-date details.
