The tone is OK, but there are quite a few mistakes. Dear sir. I hope my words find you well. I would like you to note that I haven't turned off my mobile. My number is ************** and I'm looking forward to receiving a call from you soon sincerely My Name 'sinisterly' was what we call a 'freudian slip' - a mistake that has a very different meaning! 'I would like' is less direct than 'I want' - I think that is more polite.

I would just add to Gary's reply that you it does seem a little 'wordy', which means you could say the same thing much more simply. I would also note the capital letters and the spaces (although I'm not sure that this is really important as you were focusing on the language corrections). My suggestion is: Dear Sir, I hope you are well. Please note that my mobile is not turned off. My number is ************** and I look forward to hearing from you. Sincerely, My Name

In formality, this would be my version: Dear Sir (if you know the person's name, it is best to address Mr. ##### for example) I hope this day finds you well. I am still available on my mobile phone and please feel free to contact me at ########### , at your earliest convenience I look forward to speaking with you. Regards, Islam ( last name as well )
