Network coverage for OneCard smart cards

The OneCard chip operates on two cellular LPWAN standards — NB-IoT and LTE-M. Below is current country and operator data as of August 2026: where each standard works, who the operators are, and where the gaps are.

132NB-IoT operators worldwide (GSA)

50+countries with LTE-M networks

2major NB-IoT shutdowns: AT&T, Docomo

3technologies in the chip: NB-IoT + LTE-M + NTN/LoRa

NB-IoT · PRIMARY STANDARD

NB-IoT coverage by country

Europe, China, South Korea, Australia, Brazil, MENA, South Africa — operator by operator: Deutsche Telekom, China Unicom, KT, Vodacom, stc and more. Statuses, trends, sources.

LTE-M (Cat-M1) coverage by country

North & South America, Japan, South Korea, Europe: AT&T, Verizon, NTT Docomo (99.8% population), SK Telecom, Vivo. Plus an LTE-M vs NB-IoT comparison for OneCard scenarios.

Why two standards. NB-IoT is more energy-efficient and penetrates buildings deeper — ideal for static cards. LTE-M supports handover and higher speeds — it works where NB-IoT does not (especially in the Americas) and remains primary for operators winding down NB-IoT (AT&T — Q1 2025, NTT Docomo — 2020). NB-IoT roaming is limited, which makes the multi-technology chip a strategic choice. Satellite NTN and LoRa mesh cover the zones beyond cellular reach.
