Open Market Handsets (OMH) is a CDG industry initiative focused on expanding access to a variety of CDMA handsets through open handset distribution. This open access is achieved through independence of OMH devices from operator-specific provisioning.
- An OMH device operates seamlessly on any CDMA OMH operator network, including full subscription portability for voice, SMS, 1x data, EV-DO data, WAP, MMS, BREW, Java, and Location Based Services.
- An OMH device exhibits proven quality, performance, and interoperability. One-time standards-based testing provides device certification for all OMH operators and markets.
Many Qualcomm chipsets support Open Market Handset features.
Open Business Model
The OMH mobile device manufacturer has access to the worldwide open CDMA market where it can sell mobile devices directly to consumers and retailers, in addition to selling to network operators. Manufacturers also have the ability to partner in local markets with distributors and brands. Go to Markets
When an open CDMA device is termed OMHTM it means the device is always unlocked for all networks and the device is usually promoted with one or more operators. A device manufacturer can easily add a MIN-lock or SIM-lock function on an OMH device that will be distributed as an operator procured device.

Compliance to CDG
OMH is an industry initiative led by CDG. It is important for the device manufacturer to understand and follow CDG development and testing specifications, before designing and developing an OMH product.

Testing
One-time test results from a lab that is qualified to execute the required testing coverage can be used across all OMH markets.

Parent-Variant Concept
Device variants are new OMH devices based on a "parent” device that was previously accepted by the TAG. Variants have only minor modifications relative to the previously accepted parent device and therefore do not need to be re-tested except for the minor differences in functionality. An example of a modification that would not qualify as a variant would be a device with a different PCB.
Once a device manufacturer has gone through the full OMH process for a parent device, it may continue to design and develop variant devices based on the parent, per the following criteria:
Multi-mode Devices
Maximize your investment for an OMH device across CDMA/UMTS/GSM by offering a multi-mode device. A multi-mode device should be compatible with OMH CDMA on 800/1900, GSM 900/1800, and UMTS/HSPA 2100.
The following steps outline the high-level process for creating OMH-compliant mobile devices. To obtain Qualcomm support, visit this page.
TAG = Test requirements and Acceptance Group
- Defines and manages OMH testing requirements
- Accepts OMH devices and networks
- Maintains an ecosystem website of accepted OMH devices and networks
