Set up carefully. Test locally.

Never use Groupyid for emergencies. Carrier messages can be delayed, filtered, duplicated, reformatted, or undelivered.

Safe setup checklist

  1. Use a dedicated compatible Android gateway and an authorized mobile line.
  2. Install the trusted APK, make Groupyid the default SMS app, and grant only the requested SMS, phone, notification, and battery-reliability access.
  3. Select and verify the exact gateway SIM and number.
  4. Add each member only after consent; start with a small test group.
  5. Use Dry Run to inspect routing, batching, commands, limits, and suppression.
  6. Enable Live locally only after carrier permission and physical tests are complete.

Background reliability

Android may stop background work to save battery. Groupyid explains missing access at startup and links to Android’s battery-optimization screen. Keep notifications enabled so the active relay and queue are visible. Recheck these settings after an OS update or device migration.

Flip-phone members and SMS administrators

Flip phones text the dedicated gateway number and need no app. Members can use HELP, STATUS, GROUP, MUTE, UNMUTE, LEAVE, STOP, and START. An administrator may be separately allowed to manage ordinary members using the private, confirmed GY command flow. Malformed or unconfirmed management commands are never broadcast.

Reaction roundup

When enabled, a burst of short reactions can be collected into one summary instead of sending every “Mazel tov” separately. The administrator chooses the window, can arm only the next announcement, and can release a pending roundup early. Ordinary messages outside the narrow reaction rules continue normally.

Messages do not relay

Confirm the app is the default SMS handler, the exact gateway SIM is selected, required permissions and notifications remain granted, the relay is not paused, the sender is enrolled or safely linked, consent and STOP state permit delivery, and the queue is below its configured limits. Do not repeatedly resend until the original delivery state is known.

Text-only MMS Beta

The Beta is off by default and sends a separate text-only MMS to each verified recipient only when an eligible transcript would otherwise require multiple SMS parts. Carrier support, APN/mobile-data behavior, costs, callbacks, and flip-phone rendering vary. Test each recipient and carrier plan before relying on it.
