Push notifications and in-app messages:
If you're using either of our iOS or Android apps you will receive in-app messages or push notifications. These are delivered to the GroupMe app using your data plan.
If you choose to receive SMS, messages will be delivered as text messages and will count towards your text plan in the same way as normal SMS messages. SMS is currently supported within the United States only.
If you have a smart phone, we recommend using the app. We've worked really hard at making our apps an awesome experience, and lots of features we've recently implemented just aren't available with SMS. Using SMS, you're missing out on sharing pictures, videos, our custom emoji, gifs, and so much more.
