Key Takeaways
- Retail use cases for an Android phone as SMS/MMS gateway: order updates, pickup ready, appointment nudges, and occasional product photos — on your SIM.
- Consent separates transactional updates from promo blasts.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Operator SMS/MMS charges are yours.
- Free 300 SMS lifetime is a canary, not Black Friday.
- Isolate OTP/login from marketing SIMs.
- Pace blasts; OEM and carrier fair-use still apply.

Retail SMS and MMS lanes
Keep pickup/order texts short. Use MMS when a photo/PDF helps (alterations, custom orders). Confirm send shapes in Developer Center.
