Here's how the text messages you send and receive might look if you were going to catch a RIBS4 bus at Fountain Drive at Cameron Avenue (which stops at stop ID 1971). The bus stop sign at the stop will say to: "Text FFX 1971 to 41411 for estimated arrival times."
NOTE: When you use BusTracker via text for the first time, the system asks you to confirm your request - just respond with "Y" to confirm.
This example response says that, as of 2:25 PM, at stop 1971 (at Fountain Drive at Baron Cameron Avenue), BusTracker estimates that a RIBS4 bus to North Point and Wiehle Metro is due to arrive in 7 minutes, and then another one should arrive in about 48 minutes.
You can also reply to this message with "S" to get any service bulletins that may affect your trip, or "R" to get the latest, most updated result for the same stop.
If your stop has multiple routes serving it, your results may not fit in one text message. In that case, you can also reply with "N" to see the next result for the stop you requested.
If you have subscribed to receive text messages for service alerts or arrivals at scheduled times from the Fairfax Connector BusTracker website, you can always reply with (or send a new text with) "STOP" to unsubscribe.
