Send & Receive SMS

I would like to send and receive sms with my Arduino Project. I have an A6 SIM900A GSM Module with me which is from Chinese. However, it won’t work and accept any AT commands.

So, I have decided to buy a new one. I need a suggestion which is the simplest GSM Module or maybe more references I can refer to on Internet

I just got the “Too many requests” ban on Stack Exchange, which lasts about 5 minutes. I’m still trying to avoid the ban again, but I do still worry the next time I receive the ban, it would last a little longer.

I can not receive files from my phone by bluetooth

I can not send files by bluetooth from my cell phone to the computer, they always give an error and do not send (I do not get it on the computer that is trying to get a file to accept it or deny it)

The funny thing is that from the computer files can be sent correctly to that mobile by bluetooth.

I have looked at all the possible configuration options, I have tried the blueman also and nothing at all, I do not know what to do …
