Now Send / Receive and Read SMS in Facebook Messager (FBM)

Recently Facebook Messenger introduced the feature which gives the users an access to their SMS messages without leaving the FBM app.

With this feture Facebook Messenger invading in the domains where WhatsApp and Go SMS Pro are big players, Facebook Messenger needs to learn some fetures from these 2 apps to become the most desired application for messaging.

for example;

1. Spam filters to filterout unwanted messages. Because they are very much annoying for some users like me.
2. Most mobiles are now dual SIM so why not support this feature? Although it receives SMS on both SIMs but reply from the default SIM only.
3. Equal ease of access to SMS on webapplication, I myself love using messaging app like WhatsApp and Messenger on desktop, I also use Airdroid to send and receive SMS. 

If FBM offer these features then in my opinion it will become desired app for the many.
