China: 4G and 5G bands, and what works for IoT

4 networks · Checked 2026-09-30 · next check by 2026-12-31

China has four operators: China Mobile, China Telecom, China Unicom and China Broadnet. China Mobile’s 4G is mostly TDD (B34/B38/B39/B40), with only B3 and B8 on FDD; China Telecom and China Unicom run mainly FDD B1 and B3, plus B5 (Telecom) and B8 (Unicom); China Broadnet uses B28 for 4G. For 5G, China Mobile uses n41 and n28, Telecom and Unicom share n78 and n1, and Broadnet shares n28 with China Mobile. China Mobile, China Telecom and China Unicom all run commercial 5G SA and RedCap. 2G and 3G are being switched off.

Huawei E5576-320：One of the most common travel pocket Wi-Fi units; no North American B2, B4, B12, B66 or B71, and no 2G.

TP-Link M7350：No B28: in countries that rely on 700 MHz for coverage (Australia, much of Latin America) the rural signal will be weak.

Quectel RM520N-GL：Full 5G (eMBB, NSA and SA), not RedCap; B29, B32 and n29, n75, n76 are downlink only.

Quectel BG77：LTE-M and NB-IoT are assessed together: B14, B26 and B27 are LTE-M only, B71 and B85 are NB-IoT only.

Quectel BG770A-GL：LTE-M and NB-IoT are assessed together: B26 and B27 are LTE-M only, B17 is NB-IoT only.

Quectel BG95-M3：LTE-M and NB-IoT are assessed together: its LTE-M also has B26 and B27, its NB-IoT also has B71.

u-blox SARA-R510M8S：LTE-M and NB-IoT are assessed together: B25 is LTE-M only, B66, B71 and B85 are NB-IoT only, and the “00” versions do not support NB-IoT.

Nordic nRF9160：Bands are those Nordic lists as certified so far; LTE-M and NB-IoT are assessed together.

Quectel EC25-E：The EC25-E has no B28; where B28 is needed (Australia, New Zealand, Israel and others), choose the EC25-EU or EC25-EUX from the same family.

Quectel EC200U-EU：In the same family, the EC200U-AU adds B2, B4 and B66, and the EC200U-CN is for China.

SIMCom A7670E：The A7670E has no B28 and no Americas bands; where they are needed, choose the A7670SA from the same family (B1/2/3/4/5/7/8/28/66).

SIMCom SIM7080G：LTE-M and NB-IoT are assessed together: B14 and B27 are LTE-M only, B71 is NB-IoT only, and the SIM7080G-M supports LTE-M only.

Quectel BG96：LTE-M and NB-IoT are assessed together: B39 is LTE-M only, B25 needs release R1.2 or later, and the BG96-M supports LTE-M only.

Quectel EG21-G：The same 4G bands as the EG25-G at Cat 1 speed (up to 10 Mbit/s), suited to low-data, cost-sensitive devices.

u-blox LARA-R6001D：The D version is data only; for North America, the LARA-R6401 in the same family adds B14, B66 and B71.

Telit ME910C1-WW：LTE-M and NB-IoT are assessed together; the newer ME910G1 family adds North American bands such as B25, B66 and B85, and its versions differ, so check before choosing.

Quectel RG255C-GL：The specification is a preliminary release; the module is certified on T-Mobile. 5G needs 5G SA with RedCap on the network; elsewhere it falls back to LTE Cat 4.

Teltonika TRB140 (0*****)：Listed by the maker as B28A, the lower half of 700 MHz; the few operators using only the upper half of B28 may not work. For the Americas, choose another version.

Teltonika TRB140 (1*****)：No B20 (the 800 MHz coverage layer in Europe): it works in European cities, but suburban and indoor coverage will be weaker; and no B12, B13, B66 or B71, so not for the United States.

Teltonika RUTX12 (0*****)：The maker also lists B32 (1500 MHz), receive-only and only as a secondary carrier in aggregation, so it is not counted as a band that can carry a connection alone. Excludes Japan and China Mobile; no 2G.

Teltonika RUTX12 (1*****)：The maker also lists B29 (700 MHz), receive-only and only as a secondary carrier, so it is not counted. No B71 (T-Mobile 600 MHz); no 2G.

Teltonika FMC130-ME3：Built on the MeiG SLM320-E2 module, LTE Cat 1 with 2G fallback; no 3G. For the Americas, choose the FMC130-MCIB0.

Teltonika FMC130-MCIB0：Built on the MeiG SLM320-LA module, LTE Cat 1 with 2G fallback; no 3G. No B12, B13, B66 or B71: not for the United States.

Quectel EC25-AF：The North American version for Verizon, AT&T, T-Mobile, U.S. Cellular, Rogers and Telus; no B1, B3, B7 or B20, so not for Europe or Asia.

Quectel EC25-EUX：Adds B28 over the EC25-E (listed as B28A, the lower half of 700 MHz) but has no B5.

Quectel EC25-MX：Designed for Mexico: B4, B7 and B66 for Telcel, and B28, the only band Altán uses.

Quectel EC25-AU：The maker notes that B2 on the EC25-AU has no receive diversity, so performance drops in weak signal. No B20, B12 or B13: not for Europe or the United States.

Huawei E3372h-320：Per its GCF certification record: LTE B1, B3, B7, B8, B20 and B28, no TDD. Some listings quote the bands of the E3372h-153 (without B28), so check the suffix when buying.

USR IOT USR-G771-E：LTE Cat 1 for the mainstream European bands, with 2G fallback; no B5, so not for the Americas. The Chinese USR-G771 has different bands; do not mix them up.

USR IOT USR-DR154-E：LTE Cat 1, tiny and DIN-rail mountable; the Chinese USR-DR154 has only B1, B3, B5 and B8, so pick the -E version for deployments abroad.

Good: the main bands and the coverage layer are all supported. Limited: it connects, but some main or coverage bands are missing, so signal is weaker in some areas or indoors. Not usable: no band in common.

Certification details come from Hyper Nexus product data.70

Network access: long-term roaming

Many globally deployed IoT devices use multi-network roaming SIMs that can attach to several networks in a country, but some countries restrict long-term roaming by foreign SIMs. A local SIM roaming domestically is not affected.

⚠ Long-term roaming by foreign SIMs is not allowed: Long-term use of foreign SIMs is not allowed; a domestic operator’s SIM is required.717273

Questions

Why do many foreign modules struggle on China Mobile?

China Mobile’s 4G is mostly on TDD bands B34/B38/B39/B40, with only B3 and B8 on FDD. An FDD-only module can use just B3/B8 there, so coverage and capacity are limited.

Which Chinese operators run 5G RedCap?

China Mobile, China Telecom and China Unicom have all launched it (per GSA). RedCap devices need the operator’s 5G SA network.

Do 2G and 3G still work in China?

They are being switched off: China Mobile’s 2G licence for 900/1800 MHz ended on 31 December 2025; China Unicom is closing 3G province by province (Zhejiang on 15 June 2026); China Telecom has been closing CDMA since 2020. Design new devices for 4G, 5G or NB-IoT.
