Their 5G plans are more expensive but offer higher data limits. MVNOs like Mobi Taiwan using their network provide low cost prepaid options.

4. Taiwan Star

As the newest 4G-only operator, Taiwan Star has the lowest population coverage so far. But it offers the lowest rates to compensate starting from just NT$499 per month. Their prepaid SIM packs come with free data too.

But network speeds and reliability are weaker compared to the top 3 operators. Customer service is limited too with no English support. Retail network is small with stores mainly in Taipei.
