Sample 3GP Files — Download Mobile-Phone Test Videos
3GPP mobile video · .3gp · MIME type video/3gpp
Download a sample 3GP file — the format feature phones and early Android devices recorded in, still produced by some low-end handsets and MMS gateways. It is a stripped-down MP4 with low resolutions and bitrates, which makes it a good test for players and thumbnailers that assume HD dimensions.
Our samples use MPEG-4 Part 2 video and AAC audio at CIF (352×288) and 640×360, matching typical device output.

Frequently asked questions
Do modern phones still record 3GP?
Rarely. Android and iOS record MP4/MOV now, but MMS gateways, some budget phones and older apps still emit 3GP, so an upload form that has been live for years will see it occasionally.
Are these 3GP files safe to download?
Yes. Every file is generated by our own open script from scratch — nothing is scraped or user-uploaded — and contains no scripts, macros or executables. The SHA-256 of each file is published on this page so you can verify what you received.
Can I use the sample 3GP files commercially?
Yes. They are free for any purpose, including commercial products, test suites, demos and redistribution, with no attribution required. There is nothing to license and no one to ask.
Can I hotlink these files or use them in CI?
Yes. Every link is a stable direct URL over HTTPS with Access-Control-Allow-Origin: * and long cache headers, so curl, wget, fetch() and test runners can pull them directly. A JSON index of every file is linked from each page (see the command-line section).
