Frequently Asked Questions

MacSMS is a free service which allows you to receive the most accurate weather updates and bus schedules via text messages. We developed the service exclusively for the McMaster community.
The weather forecasted by other sources can vary up to 8 degrees for McMaster and the surrounding areas. We leverage data from McMaster's very own weather station located on the campus to provide you with the most accurate updates (accuracy of ±0.2C). Also, the data is updated every 15 minutes and you don’t need to be connected to wi-fi to use the service. The bus command helps you save time and money by simply texting to find bus schedules instead of calling.
The service is free to send and receive messages. You can incur regular charges from your cellular provider but only if you go over your messaging limit. You will not be charged if you have unlimited text messaging.
Use the form above to sign up. During registration, select the time you would like to get your daily weather update. After that, you can text keywords such as “weather”, “wind”, “bus” anytime to get the updates. The reminder time can be turned off or changed once you register.
Yes! All your information is safe and encrypted. Your information will not be disclosed to any third-party companies. It will be used strictly for providing you with weather updates. Your trust is more valuable to us than making a couple of bucks.
If you need to change any of your personal information (including number, email, reminder times), please log in through the Settings button. If you have any difficulty, please email us at
Currently you can find out about temperature, wind speed and forecast. You can use text C and F to switch between Celsius and Fahrenheit. Keep in mind that all the commands are case insensitive.
