Free allowance: No storage quota is stated on the Media subresource page: Twilio retains stored media until the Media subresource instance is deleted.
Verdict: paidno free allowance; listed for its price
Cost: no price stated
Identity: any-phone?placeholder, not evidence; card unknown, phone unknown
Binding limit: per-object-cap5 MB total media per message, up to 10 media files
Evidence: documented9 sources; a first-party page was read and the sentence quoted
Freshness: stale on 2026-12-05checked 2026-11-04 (live); stale on 2026-12-05

Free tier	No storage quota is stated on the Media subresource page: Twilio retains stored media until the Media subresource instance is deleted. Media arrives through billed messages: MMS outbound $0.022 and inbound $0.0165 per message on a long code. unit unlimited; metered on stored-bytes
Price	none stated
Limits	per-object-cap (binding) 5 MB total media per message, up to 10 media files source 5 MB TOTAL across up to 10 files per message; 'Twilio rejects messages with over 5MB of media'. Paid per message ($ per MMS segment), not a free tier. Carrier-grade resizing mangles images.
Binding	per-object-cap 5 MB of media per message, and every message is billed, so capacity is paid for per message
Identity	any-phone (placeholder) trial sign-up verifies an email address and a personal phone number and needs no credit card; the identity needed for a paid account that sends MMS is unverified
Egress	Authenticated only, and Twilio says so outright: 'If you need to embed media in web applications without exposing your credentials, download the media files and serve them from your own server or cloud storage service.' No public URL, ever.
Per-object cap	5 MB total across up to 10 media files per message; Twilio rejects messages with over 5MB of media
Retention	No quota — media is retained indefinitely
Interface	rest rest
Tooling	twilio-python / twilio-node; .media.list() and .media(sid).fetch(). Clean API, but nothing removes the auth requirement.
Composes with	5 MB per message is the wall. To reach 1 TB you need ~200,000 MMS, each billed per message — this is the opposite of a free tier. Retention is excellent and completely unusable at this scale.
Reliability	The best retention semantics in the slot (never expires unless you delete) ruined by a 5 MB message cap and per-message billing. Interesting only as proof that indefinite retention is commercially possible.
Notes	No quota — media is retained indefinitely. The docs say Twilio 'retains the stored media until you delete the related Media subresource instance', i.e. retention is customer-controlled and unbounded in time.
Evidence note	documented read 2026-11-03: https://www.twilio.com/docs/messaging/api/media-resource (5MB and 10 files per message; retention until deletion), https://www.twilio.com/en-us/sms/pricing/us (long-code MMS prices) and https://www.twilio.com/docs/usage/tutorials/how-to-use-your-free-trial-account (trial phone verification, no card), all vendor pages; paid-account identity not read.
