Mozillion’s SIM-only plan sits in the “big data, low commitment” end of the market, competing with other MVNOs that bundle generous allowances without tying you to a handset. If you’ve already got a decent phone and just want a predictable monthly bill, 100GB of 5G data with unlimited minutes and texts is aimed at heavy scrollers, commuters and hotspot users who don’t want to babysit their usage.
Who is 100GB actually for?
It’s overkill for light users on Wi‑Fi, but it starts to make sense if you stream video on the move, use your phone for work calls, or share data with a laptop. 5G access helps in busy areas where 4G can feel congested, though real-world speeds will still depend on local coverage. EU roaming is useful for short trips, but it’s worth checking any fair-use limits and which countries are included before you rely on it.
- 100GB 5G data — enough for regular streaming and tethering without constant top-ups
- Unlimited minutes & texts — removes the need to track call/SMS usage
- EU roaming — convenient for travel, subject to policy and allowances
