Key Takeaways
- Clinic SMS should identify the practice, give a time window, and tell the patient how to change — not what is wrong with them.
- Default to GSM-7. A Unicode dash or emoji is how a one-segment reminder becomes two SMS and a truncated time.
- Portal OTP templates stay on a dedicated SIM and a dedicated body. Do not reuse reminder copy.
- A clinical lead signs templates. Reception improvising “your results are abnormal” in SMS is an incident.
- You bring the phone and operator credit. Each part meters platform volume and airtime.
Companion to the clinics playbook. Intent: android sms gateway for clinics — specifically the bodies you put on the wire. Patients will screenshot them. Operators will store them. Roommates will read them.
You send through your SIM. Pricing is devices plus send volume; operator airtime is yours. Scheduled SMS for cadence; privacy policy for the product’s own handling.
Pass · GSM-7
Riverside Clinic: Thu 10:00. Reply C to change. Do not reply with medical details.
Rules before a single character
- If you would not announce it at reception, it is not an SMS.
- Prefer “results ready in the portal” over any value.
- One job per template: reminder, prep, delay, OTP — never a mashup.
- Include how to opt out of optional programs; reminder exceptions go through counsel.
The template is the control. The gateway will not refuse a well-meaning paste. Training will.
Template bank
| Job | Example shape (not legal copy) | Avoid |
|---|---|---|
| Booking confirm | Clinic name, weekday, time, change path | Reason for visit, clinician full notes |
| 24h reminder | Same + “arrive 10 min early” if needed | Fasting + diagnosis in one novel |
| Prep | Generic prep (“no food after 10pm”) signed by nursing | Drug names the patient did not already have in a portal |
| Running late | “Delay ~20 min. Stay or reply C.” | Other patients’ names, incident detail |
| Results ready | Portal nudge only | Numbers, “positive,” attachments |
| Portal OTP | Brand + digits + expiry; dedicated SIM | Reminder language, links, emoji |
Industry SMS tone: messaging best practices. Health privacy is stricter; this table is a floor.
Segment budget
GSM-7: 160 characters (153 once concatenated). UCS-2: 70. Clinic names in local script, fancy hyphens, and emoji flip the encoding. Count the rendered patient name, not {name}. Free-plan canaries may append www.sms-gateway.app — budget it or the time falls off the end.
Tokens that blow UCS-2
Long Unicode surnames, curly quotes from Word, a single emoji “for warmth.” Warmth is a phone call. Keep variables boring: date, time, location code. Canary the longest name on a real handset.
OTP is not a clinic reminder
Different SIM, different template, different owner. OTP template how-to and OTP use case. Never put the code in a reminder body “while we have them.”
Who signs the copy
Medical lead for clinical-adjacent prep. Front desk for logistics. Engineering for OTP. Change control: a Slack edit is how PHI lands in production. After OEM or app updates, re-canary. Real handsets.
Live substitution fields: Developer Center.
