Need Videos for CDMA Devices?

You have 3GP video files from a GSM phone, but your target device uses CDMA technology and requires 3G2 format. This is a common situation when transferring videos between carriers or working with legacy mobile devices.

Both 3GP and 3G2 are mobile video formats designed for 3G phones, but they were created for different cellular standards. Converting ensures your videos play correctly on the intended device without compatibility errors.

How to Convert 3GP to 3G2

  1. Upload your 3GP file - Drag and drop or click to select your mobile video
  2. Confirm 3G2 output - The CDMA-compatible format is selected automatically
  3. Download your video - Ready for playback on CDMA devices

The entire process takes seconds. No software installation, no account creation required.

3GP vs 3G2: Understanding the Difference

Both formats are container formats based on the MPEG-4 standard, but they serve different mobile ecosystems:

  • 3GP (3GPP) - Designed for GSM-based phones using UMTS technology. Common in Europe and many international markets.
  • 3G2 (3GPP2) - Created for CDMA-based phones using CDMA2000 technology. Used by carriers like Verizon in the US and Reliance in India.

In our testing, the visual quality remains identical after conversion since both formats support the same video codecs. The difference is in audio codec support - 3G2 can store EVRC and QCELP audio streams that 3GP cannot, making it better suited for CDMA voice network integration.

When You Need This Conversion

Legacy Device Support

Older CDMA phones from the mid-2000s often only recognize 3G2 files. If you are maintaining content for these devices, conversion is essential.

Carrier-Specific Applications

Some carrier multimedia services and legacy MMS systems expect specific formats. Converting ensures delivery without rejection.

Archive Migration

Moving video archives between different mobile platform ecosystems may require format standardization to 3G2 for CDMA-based libraries.

Technical Specifications Preserved

When converting from 3GP to 3G2, these properties are maintained:

  • Video resolution and frame rate
  • H.263 or H.264 video codec settings
  • AAC or AMR audio quality
  • Metadata and timing information

The 3G2 format actually offers slightly better compression efficiency, potentially resulting in marginally smaller file sizes with identical visual quality.

Alternative Conversions

If you need broader compatibility beyond CDMA devices, consider these alternatives:

  • 3GP to MP4 - For universal playback on any modern device, smartphone, or computer
  • 3G2 to MP4 - After converting to 3G2, you can later convert to MP4 for desktop playback

For most users today, MP4 is the better choice unless you specifically need CDMA device compatibility.

Works in Any Browser

Convert 3GP to 3G2 directly in your web browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • iPhone, iPad, Android devices

No downloads or plugins required. The conversion happens securely and efficiently.

Pro Tip

If your 3GP file contains AMR audio, the conversion to 3G2 preserves it perfectly since both formats support AMR. However, 3G2 can also store EVRC audio which offers better voice quality on CDMA networks.

Common Mistake

Converting to 3G2 when you actually need universal playback. If your goal is playing videos on computers or modern phones, skip 3G2 and convert directly to MP4 instead.

Best For

Legacy CDMA device support, carrier-specific multimedia systems, and maintaining archives originally created for CDMA2000 networks like Verizon or Reliance.

Not Recommended

General video sharing or modern device playback. Both 3GP and 3G2 are legacy mobile formats - use MP4 for anything that does not specifically require CDMA compatibility.

Frequently Asked Questions

3GP was designed for GSM phones (UMTS technology) while 3G2 was created for CDMA phones (CDMA2000 technology). Both are mobile video containers based on MPEG-4, but 3G2 supports additional audio codecs like EVRC and QCELP used in CDMA networks.

No. Both formats support the same video codecs (H.263, H.264). The conversion changes the container format, not the video encoding. Your video quality remains identical after conversion.

3G2 is required for CDMA carrier devices and services. If you are working with Verizon legacy devices, Reliance network content, or CDMA-specific multimedia systems, 3G2 ensures proper playback and compatibility.

Most modern smartphones can play both 3GP and 3G2 files. However, for broader compatibility with desktop computers and web applications, converting to MP4 is recommended unless you specifically need the mobile format.

3G2 offers slightly better compression and supports additional CDMA-specific audio codecs. However, 'better' depends on your use case. For CDMA devices, 3G2 is better. For GSM devices or general use, the difference is negligible.

Conversion typically completes in seconds for standard mobile video files. Since 3GP files are usually small (designed for mobile data limitations), processing is very fast.

Yes. Upload multiple 3GP files and convert them all to 3G2 in a single batch. This is useful when migrating entire video libraries between format standards.

While largely replaced by MP4 on modern smartphones, 3GP and 3G2 remain relevant for legacy device support, carrier multimedia services, and archived mobile content. Some feature phones and older systems still require these formats.

3G2 supports EVRC, EVRC-B, EVRC-WB, 13K (QCELP), SMV, and VMR-WB audio codecs that are specific to CDMA networks. These are not available in the 3GP format, which focuses on GSM-compatible audio codecs.
