Ok basically all I want to do is transfer my SMS messages to my PC because my phone is getting very slow from the amount of space being used up by text messages.

I've read about how you can install an app that does this, via Google or something, but I just can't dot that because for some stupid reason my phone hasn't come with an Andriod market app or a Google Play app, so when I go on the browser it tells me I can't install that app because I haven't signed into Google Play on my phone before, and like I said, I just can't.

I've also tried backing the SMS files along with other files up on my phone, which makes them accessible to me via my PC when using the file manager from PC Companion, and this is an sbf file which I have been told cannot be opened on a PC.

Is there any other way I could do this?

Thanks in advance
