I usually sign in to Skype in my cell phone not in my PC.

Hello everybody,
Thank you for your helpful forum.

I have a problem with the red prepositions. I don't know which preposition should be used in this context. These are self-made. Which one is correct?

1. I usually sign in to Skype in my cell phone not in my PC.
2. I usually sign in to Skype via my cell phone not via my PC.
3. I usually sign in to Skype on my cell phone not on my PC.
4. I usually sign in to Skype with my cell phone not with my PC.

Thank you.

My first choice is 'on'; my second choice is 'via'.

I would not use the others.

I would do the same as Rover, but 4) doesn't sound wrong to me. 1) sounds unnatural to me.

I agree with Tdol. You could also say "using my cellphone".

Note that in BrE, we say "mobile phone" or "mobile". If we use "cellphone", we write it as one word, not two.
