FAQ

Should I choose a 50GB plan or an unlimited plan?
If your monthly usage consistently stays below 30–40GB, a 50GB fixed-capacity plan often provides better value. Unlimited plans cost more upfront but become economical at very high usage volumes. However, many unlimited plans apply fair use throttling after a certain threshold, so verify actual speed limits before committing.
Can I watch 4K video on a 50GB plan?
4K content on services like Netflix consumes roughly 5GB per hour. With 50GB dedicated entirely to 4K, you would have about 10 hours. In a typical mixed-use scenario — FHD during commutes, occasional 4K at home — 50GB handles it comfortably. Also confirm that your plan delivers at least 15–25Mbps consistently.
Is a 50GB plan suitable for freelancers working on tethered laptops?
Yes, 50GB is well suited for freelancers who rely on tethering. Assuming two hours of laptop work at a cafe for 20 days per month, tethering would consume roughly 20–30GB, leaving 20–30GB for video and social media. Always check the tethering policy carefully before signing up.
