i use circles.life, good budget option and i’ve had no troubles in terms of interruptions or speed. quite pleased with it actually.
i signed up using my partner’s taiwanese card, and used a referral code (pick any at random there are heaps of them on PTT, or if you’d like you can use my referral code and I get money 
), so it saves 100NTD a month for 6 months i believe.
so yeah like @boaz25 said, it was 200NTD to activate, but i only pay 450NTD a month for unlimited cause the referral system.
