5 stars: Google carrier services is designed to assist carriers bringing in new features to the messaging app. It allows MMS and newer features to be used by your carrier. It's not spying on you, and it's not breaking your phone. Look it up if you really have to, or get a custom ROM and remove Google apps all together if you really despise them.
3 stars: After reading a bunch of comments below, I began to wonder if this app is why I have to restart my phone every day...at least once... sometimes 2 or 3 times just to get it to operate properly.
4 stars: There's no waiting period before a missing practice can be reported to the important reports. Carrier Reports it immediately and have information they will need on hand.
5 stars: This app is really ahead of its time. With the next few updates, I think this app has the potential to find a vaccine for Corona virus before the rest of the world. Colour me impressed because this app handles my carrier network like no other battery intrusive app on my phone.
5 stars: This application is handy for telling me about the status of my mobile data for the month, it's useful because it will give me up to 2.5 gigs that was unused by my use for the month. If I top up my phone a couple days early I got the extra data that I didn't use. Thanks again for the great service.
5 stars: Absolutely necessary if you want your phone to work correctly. Without it, unlocked phones can have some minor issues with carriers.
