FAQ

Can I use both video streaming and tethering on 10GB?
Yes, with careful management. Limiting video to 30 minutes per day (around 2–3GB/month) and tethering to 2–3 sessions per week at one hour each (roughly 3–4GB/month) keeps total usage within 5–7GB. However, using both at full capacity can push you beyond 10GB, so monitoring your usage mid-month is advisable.
Is 10GB enough for remote work?
For text-based remote work — email, chat, document viewing — 10GB is often sufficient. However, daily HD video calls on Zoom or Google Meet consume roughly 1.5GB per hour. At full-time remote work pace, five days a week, you could exceed 20GB per month. If you have frequent video calls, consider a 20GB or unlimited plan.
Which offers better value: 10GB or 20GB?
If your monthly usage consistently stays below 7–8GB, the 10GB plan is more cost-effective. Paying for 20GB you never use is wasteful. On the other hand, if you regularly run out near the end of the month or use tethering frequently, the 20GB plan delivers better practical value despite the higher price.
