It is a cost reducing app for dualsim users. While making phone calls, it automatically chooses the most cost effective sim depending on the sim, active package of the caller, time, operator of the dialed user and makes call directly from that particular sim.

2. Introduction
●“Dual SIM Cost Management” is an automated cost
reducing application for dual SIM users.
●When a call is made, the app will select the cheapest rate for
the call between two SIMs and made the call through that.

3. Our primary development plan involved using Tab
layout to implement keypad, setting menu and
instructions.
The keypad should receive the number the user
wants to call and pass the call automatically through
the cheapest option.
The setting menu should receive the package
information and FnF numbers from user. It should
also receive phone set type.
Plan

4. Introduction
●No other people in the world have yet thought about this
idea as far as we know.
●This app will bring revolution in the app industry.
●People will be greatly benefited by using this app as it will
save their money and time.
●There is no similar app like this one.

5. Introduction
●All classes of people including local and global can use this
app.
●As it will be built globally, supported language will be
English
(we can also provide a special version for local users that
support Bengali language.)

6. Implemented feature
The keypad tab uses android built-in keyboard
to receive user input.
The settings tab performs four kinds of
operations including:
-Receiving FnF numbers for SIM 1
-Receiving FnF numbers for SIM 2
-SIM packages selection
-Phone Set Selection

7. Implemented feature
After all selections are made, the app is ready to
take numbers and make the calls automatically.
The instruction Tab tells the user how to use the app
effectively.

8. Business Scope
●As our main target is to help all classes of people, the app
will be available with one time pay.
●When the user is online, we can advertise for additional
income.
● This app might be very attractive to mobile companies
because it will promote their sale. So they will be highly
interested in buying this app(like WhatsApp ).

9. Socio-economic Development
●As a cost reducing app, this app will save money for
customers.
●Imagine a user saving .25 TK/minute. Then 4 TK will be
saved after 10 minutes. So 10 million users will save 40
million TK.

10. Design
●This app will require android 4.0.4 (ice cream sandwich) or
higher to run on the device.
●The UX design will be somewhat like this.
keypad logs contacts Update packages
Here keypad , contacts number etc will
Show.

11. Design
●The user will select his preferable options from the
app and input his FNF numbers, special offers and so
on and the records will be saved in the phone memory
using SQLite.
●The app can be updated when any mobile operators
introduce new packages. Some highly used packages
are given default in the app.
●This app will need user message inbox access (for
FNF numbers) and SIM selection.

12. Development Plan
●Application development work will be equally distributed to
team members.
●Android platform will be used.
●The user will select the SIMs he has been using from
selection menu and put FNF numbers for each of them.
●For special offers, there will be options for default SIM
selection for certain period of time.
●User input data will be stored in the phone memory using
SQLite.

13. Future Plan
●We want to make it available for our country people
so that people can use it easily.
