Remindavo delivers automated phone call reminders to Chunghwa Telecom, FarEasTone (including former Taiwan Mobile), and Asia Pacific Telecom numbers across Taiwan. Connect your Google Calendar or Outlook and get a real phone call before every meeting — no notification to swipe away.
Taiwan has three active mobile network operators (MNOs) following the 2023 consolidation of the market from four to three carriers. All three networks are supported by Remindavo.
Taiwan's largest mobile operator and state-owned telecommunications incumbent, operating under the Ministry of Digital Affairs (MODA, 數位部). CHT holds approximately 40–44% of Taiwan's mobile subscriber market. CHT mobile numbers use the 09XX format across multiple prefix ranges including 0909, 0910, 0912, 0920, 0921, 0930, 0932, 0933, 0936, 0937, 0939, 0956, 0957, 0970, and 0972 among others. CHT also operates the HiNet broadband division and provides enterprise and government network services across Taiwan. Enter your CHT number as +886 9XX XXX XXX (drop the leading 0).
Taiwan's second-largest mobile operator following the NCC (National Communications Commission, 國家通訊傳播委員會)-approved merger of FarEasTone and Taiwan Mobile in 2023. The combined entity operates under the FarEasTone brand, covering former FET number ranges (098X) and former Taiwan Mobile number ranges (097X). FET is privately held and is part of the Far Eastern Group (遠東集團). The merger also absorbed Taiwan Star Telecom (台灣之星), which had merged with Taiwan Mobile in 2022. Enter your FarEasTone or former TWM number as +886 97X XXX XXX or +886 98X XXX XXX.
Taiwan's third MNO, operating primarily on 4G LTE with number ranges in the 076X prefix. APT was formed from the merger of Asia Pacific Broadband Wireless (APBW) and VIBO Telecom in 2014 and subsequently acquired the licence of a former WiMAX operator. APT focuses on value-oriented mobile plans and has a smaller but active subscriber base. Enter your APT number as +886 76X XXX XXX.
Taiwan operates on a single, permanent time zone: Taiwan Standard Time (TST), UTC+8. Taiwan has not observed daylight saving time since 1980, making the offset constant year-round at UTC+8.
This places Taiwan in the same time zone as:
Time gap to common meeting partners: Taiwan (UTC+8) is 8 hours ahead of London GMT (Oct–Mar) and 7 hours ahead of London BST (Mar–Oct). It is 13–16 hours ahead of US time zones (EST to PST) depending on US DST. Taiwan is 1 hour behind Tokyo/Seoul (JST/KST, UTC+9) and 1 hour ahead of Bangkok/Jakarta (UTC+7). Since Taiwan has no DST, the gap to London and North America changes seasonally while the gap to Japan, Singapore, and ASEAN stays constant.
All Taiwan mobile numbers follow the format 09XX XXX XXX — 10 digits starting with 09. To enter your Taiwan number in Remindavo, convert to international format by replacing the leading 0 with +886:
Remindavo places an immediate test call to your number when you add it, so you can confirm delivery on your specific carrier and prefix before any reminders are scheduled.
Remindavo connects to Google Calendar and Microsoft Outlook — both widely used by professionals across Taiwan's technology sector (TSMC, ASUS, Acer, MediaTek, HTC, GIGABYTE, MSI), financial services (Taipei Exchange, CTBC, Fubon, Cathay), semiconductor supply chain, and global-facing businesses in Taipei, Hsinchu, Taichung, and Kaohsiung.
Setup takes under 60 seconds:
Because Taiwan uses a fixed UTC+8 offset with no DST, Remindavo never needs to adjust for seasonal clock changes. A meeting scheduled for 14:00 TST in February and an identical meeting in August both receive their reminder calls at exactly the correct local time.
Taiwan's Personal Data Protection Act (個人資料保護法, PDPA), originally enacted in 2012 and substantively amended in 2023, governs the collection, processing, and use of personal data in Taiwan. The 2023 amendments strengthened data subject rights, introduced stricter consent requirements, and established the Personal Data Protection Commission (個人資料保護委員會, PDPC) as an independent supervisory authority under the Executive Yuan — replacing the previous fragmented sectoral enforcement model.
Remindavo's data practices are built around minimisation: the service collects only your name, email address, mobile number, and calendar event metadata (times and titles). Remindavo does not record call audio, does not sell personal data to third parties, and does not retain calendar data beyond what is necessary to schedule and deliver reminders. Subscribers may request deletion of their data by contacting [email protected].
Taiwan is one of Asia's most connected technology economies. TSMC (Taiwan Semiconductor Manufacturing Company) alone accounts for a significant share of global semiconductor fabrication capacity, and its operations directly involve daily cross-timezone calls with design partners in the US, Europe, Japan, and South Korea. MediaTek, one of the world's largest chip designers, coordinates regular meetings with US and European OEM partners across the 7–8 hour time gap. ASUS, Acer, MSI, and GIGABYTE manage global supply chains with continuous video calls and follow-up calls with hardware integrators worldwide.
For professionals in this ecosystem — engineers, product managers, procurement leads, account executives — missing a cross-timezone meeting start is a costly signal. A phone call reminder before every calendar event ensures that a TST meeting at 09:00 (which may correspond to a 17:00 or 18:00 call for US West Coast partners the previous day) is never missed because a notification was dismissed during a focus session.
Beyond the tech sector, Taiwan's financial professionals (wealth managers, fund analysts, compliance officers at banks in Taipei's financial district), legal professionals, healthcare administrators, and startup founders across Taipei, Hsinchu Science Park, and the Southern Taiwan Science Park all benefit from the same core Remindavo workflow: connect your calendar, add your number, never miss a scheduled call.
Yes. Remindavo delivers phone call reminders to Chunghwa Telecom (中華電信, CHT) mobile numbers across all CHT prefix ranges. CHT is Taiwan's largest MNO with approximately 40–44% market share. Enter your CHT number as +886 followed by your 9-digit number without the leading zero. Remindavo places an immediate test call to confirm delivery before any reminders are scheduled.
Yes. Remindavo supports FarEasTone (FET, 遠傳電信) numbers across both former FET ranges (098X) and former Taiwan Mobile ranges (097X), following their 2023 merger. The combined entity is now Taiwan's second-largest MNO under the FarEasTone brand. Enter your number as +886 97X XXX XXX or +886 98X XXX XXX.
Taiwan uses Taiwan Standard Time (TST), UTC+8, year-round with no daylight saving time. Remindavo automatically converts your calendar event times to the correct local time. Since TST has no seasonal changes, there is no risk of a missed adjustment — a meeting at 14:00 TST in January and in July both receive their reminder calls at the same correct local time.
Taiwan mobile numbers start with 09 (10 digits total). For Remindavo, replace the leading 0 with +886: 0912 345 678 becomes +886 912 345 678. All CHT, FarEasTone/TWM, and APT mobile numbers use this same format.
Yes. Google Calendar operates without restriction in Taiwan and is widely used in the tech, finance, and professional services sectors. Connect your Google Calendar to Remindavo and all events on your calendar generate a phone call reminder at your chosen lead time before each one starts.
Remindavo is built with data minimisation as a core principle. The service collects only what is needed to deliver call reminders: name, email, mobile number, and calendar event metadata. Remindavo does not record calls, does not sell personal data, and does not retain calendar data beyond scheduling requirements. Data deletion requests are handled at [email protected].
Set up in 60 seconds. Remindavo calls your Chunghwa Telecom, FarEasTone, or APT number before every calendar event — no notification to swipe away.
