The best thing is that it has all of my contacts in one place, so I don't have to search for them every time! It's also helpful being able to use this app when working with other carriers such as Verizon or T-Mobile since you can just switch between networks without having your phone call drop out due too lack service from another carrier network provider (which happens often).
Sometimes there are issues connecting back into certain apps like Facebook which causes me problems at times because sometimes calls will not connect properly even though they look fine online but everything else seems okay? There really isn’t anything bad about using Cdma services; however if an issue arises where something goes wrong then we contact customer support who usually gets us connected again quickly enough unless its late hours/early morning during their work days..
