SMS alert – Mi Heart rate - be fit Review

I bought the Mi band 2 for many reasons but one was for the alarms. The one alert I wanted the most will not work on the mi fit app. It’s funny my wife has a iPhone 4s and her sms works but not email. I have a iPhone 8 with iOS 11.3 and mine works the opposite way. I see with the mi heart rate app you can only turn on sms alert if I buy it. So how can I be sure it will work if it doesn’t on other app? I would buy your app if I no for sure it will work. Can you help me fix this issue of no sms alerts? Thank you Dave
