Write a friend that I'm not available how?

Have agreed with my girlfriend that she calls me later after the sport. But my cellphone is lost somehow and I have my laptop with me, which I can call you via Skype. However, she can't call back.

How do I write her a short mail, playful and ambiguous, that I have no cell phone she should write me a mail that I can call.

What are these problems? Just write, I'm not available on the phone. Only via mail. Finished. The world will continue to turn.

Thank you. How do I write that I can call you on the laptop when she writes me a mail

You really have problems. MAKE it easy!

You really make me speechless…
