Firsty
点击星星评分
Firsty operates as a pay-per-day eSIM service with 61 data plans specifically built for China, letting you activate only the days you actually spend in the country. Unused data from past trips rolls into your account, so you can apply it to future visits without starting from zero. The platform backs this with 24/7 multilingual support covering 80 languages.
This works well for casual travelers who take multiple short trips to China and want to avoid the waste of fixed-term plans. The granular daily pricing model also suits business travelers on unpredictable schedules where a month-long subscription would go partially unused.
