At $15-20 per month, you're getting into premium MVNO territory. Plans at this price typically include 300-800GB of data, 5G access, and solid roaming packages.

This is also where you'll find promotional pricing on the main telcos' SIM-only plans.

What to Expect at $15-20

Data: 300-800GB, often with 5G included. Some plans offer 1TB at the top of this range during promotions.

Roaming: Expect 10-30GB across APAC destinations, plus a few GB for international use. Some plans include 600GB+ Malaysia data valid for a year.

Calls: Unlimited local calls are common at this price.

Network: You can get plans on any of the four networks at this price point.

Who Should Pay This Much?

Consider a $15-20 plan if you:

  • Want 5G access
  • Use significant mobile data (streaming, hotspot use)
  • Travel frequently in the region
  • Want a buffer so you never worry about running out of data

FAQ

Should I just get an unlimited plan instead? Truly unlimited plans start around $25-35. If you're hitting 500GB+ regularly, it might be worth the jump. But most people don't use anywhere near that much, so a 300-500GB plan at $15-18 is often better value.

Are 5G plans worth it at this price? If your phone supports 5G and you spend time in areas with 5G coverage, yes. But if you're mostly on WiFi or your phone is 4G-only, save the money.
