cacombos.com is positioned as a “4G/5G Bands & Combos” database, showing the band-combination capabilities of mobile devices and modems for 4G LTE carrier aggregation (CA) and 5G NSA dual connectivity (EN-DC). Its value lies in filling the gaps left by manufacturer spec sheets: many vendors only list the LTE Category and individual supported bands, without disclosing the actual CA combinations. In addition, available combinations may vary by network due to carrier policy restrictions.
The site primarily builds its data from modem logs submitted by contributors. It supports formats such as UE Capability Information, Network Signal Guru, Wireshark, Cellular Pro, hexdump, as well as Qualcomm 0xB0CD/0xB826 and Mediatek PRE_CA_COMB_INFO. It also explains combolist categories such as hardware, default, region, country, and provider, helping users understand why the same device may enable different combinations in different countries or on different carriers.
The scraped text does not disclose any pricing model, payment methods, API/SDK, open-source license, or self-hosting option. As such, it is better viewed as a public reference site rather than a standardized developer platform that can be embedded into enterprise workflows. If you need bulk lookups, automated integration, or an SLA, the currently available information is insufficient to confirm feasibility.
Its main strength is its highly focused niche: it addresses the pain point in telecom testing where manufacturers do not list CA combinations. The FAQ is fairly transparent about data sources, contribution methods, and terminology, and corrections can be submitted by email. The downsides are that the data depends on community-provided logs, so coverage and accuracy may vary by device; the content is highly technical and has a steep learning curve for general users; and there is no clearly documented interface or explanation of commercial support.
It is suitable for mobile network engineers, device testing staff, telecom enthusiasts, and anyone who needs to confirm band aggregation capabilities before buying a phone or modem. The main text does not state whether it is accessible from mainland China, so this is unknown. Alternative or supplementary sources include 3GPP standards, ShareTechnote, Network Signal Guru, Samsung Service Mode, and manufacturer specification pages.
