It happens many times we face weak signals or “Network Not Available” errors in our mobile phone, and specially when you’re connecting an important phone call, this problem irritates a lot.

For a last few days I was not able to send SMS from my Android smartphone to any mobile number. This shocked me a lot as I had sufficient balance in my SIM card but still messages was being failed again and again.

I seen many users asking how to delete their Skype chat history while using it on Android mobile. Most of the readers of All Useful Info asked the same question, and even I seen this issue unsolved on many forums.
