Key Takeaways
- In Android SMS gateway context, MMS is multimedia over the operator path — not the same as a short GSM-7 SMS.
- Needs data/APN, size limits, and a separate canary from text SMS.
- You bring the Android, SMS credit, and any MMS data plan. Platform pricing is devices plus send volume.
- Confirm attachment fields in Developer Center.
- Keep login OTP on short SMS; use MMS for rich transactional or promo lanes.

MMS vs SMS on a phone gateway
SMS is short text on the SMSC path. MMS carries media and usually needs mobile data and carrier MMS settings. Recipients still see your SIM’s number when the path is your handset.
A perfect SMS canary does not prove MMS. If you sell “picture receipts,” run an attachment canary or do not promise it.
