Key Takeaways

  • Scenario 220 is an away-fixture cancel or pitch flood at 14:20: PE office SIM dies under the parent spike — a spare already paired takes the rest. Not exam-hall moves, PTC, or late-bus.
  • Parents who get silence will idle at the gate with kit bags. The product is the second radio.
  • Do not SMS player names or the coach’s mobile in message 1. Sport, cancel, and pickup rule.
  • Staff portal OTP stays on another device.
  • Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free: 1 device / 300 SMS lifetime / 300 contacts. Developer: 25,000 SMS per year.

Android SMS gateway scenario 220 is a PE office when the away pitch floods at 13:50. The bus is cancelled. Parents need one text before pickup. Hall changes and club leaks are the wrong list.

Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Failover · Developer Center. GSMA.

PE SIM fades. The spare was already paired at lunch.

Fixture off, not a hall

Split squads across two device ids before send. Fail closed if both SIMs reject.

If you find the spare in a kit bag after the first two teams fail, you ran a car-park argument, not a cancel.

Caps: 2 / 5 / 15.

Spare already paired

Health-check both radios at 13:00 on wet days. REST: PHP, C#. MCP wraps REST.

No player names

Sport and pickup only. Identity on inbound if they reply WHICH GATE.

Devices and airtime

Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free: 300 lifetime. Developer: 25,000 SMS per year. Pricing.

14:20 blast

Doze exempt. Doze · Setup.

Fixture SIMs

Log campaign id + device id, not the squad in chat. Rotate keys. Not a CodeCanyon fixtures pack.

Two SIMs or a tannoy

If you will not keep a hot spare on wet fixture days, do not promise SMS cancels.

Checklist

  • Spare paired at lunch.
  • List split before send.
  • No names in templates.
  • Staff OTP elsewhere.
  • Webhook signatures.

FAQ

Frequently asked questions

Direct answers about android sms gateway api scenario 220.

Can we pair the spare after the 14:20 spike starts?

No. Pair it at lunch on any wet-weather fixture day. Mid-blast pairing leaves half the squads on a dead modem.

Does fixture SMS include carrier credit?

No. BYO Android and airtime. We meter devices and platform volume. Paid tiers uncap platform volume; devices still cap.

Failover fields?

Developer Center. REST samples. MCP wraps REST.
