I used way 2 sms for two months and I without using any sms pack in my airtel no. Was able to send messages through the app , in those two months I observed a lot of con of that app
The ist thing , the design and layout of the app are not good at all , now as learned from my friends they have improved it to a great extent
In addition they show the news , some quotes and jokes , apart from the news , all other things they show are old fashioned , new personality sayings should have been a great task
Once you reach a limited no. Of charCters of one messagge you cant add anymore characters as application will not allow you . If by chance message have much more text then you can send it in 3 or 4 parts which is too bad on the part of user
The no. Of messagges one can send in a day is limited , so one has to take care of it one can send only 100 messages a day
App takes longer time than many other sms apps e, g JSTsms in opening
Also it takes more time in delivering the the text more than 3 minutes which is annoying part of app
If u are planning to install an sms app I will suggest you to go for alternatives available of way 2 sms some of the fast sms apps are jstsms free text msgs etc
