I lost my phone

I am sad because today I was late to work so I forgot my phone in the bus, was not an iphone or any of those nice phones, but I had personal information and photos. I hope anybody response and take it back to me.

I feel sad today because running late for work caused me to leave my phone behind on the bus. It wasn't an iphone or any of those nice phones, but it contained personal information and photos. I hope a responsible person finds it and returns it to me.

I hope so too.

Hola Mario

"late to work" is ok, you could also say "late for work", or "late getting to work".

"so I forgot my phone in the bus" is understandable, you could also say "I accidentally left my phone on the bus".  Saying "on the bus" probably sounds odd to you, but it works!

For "but I had personal information and photos" you could use "but it contained personal information and photos"

Es bueno Mario.  Most of the corrections are not grammatical, they are more of style.
