Verifying phone number

[Frosty]

Heya
I've not been able to find an answer to my question online so I decided to try here.
I've been on AdultWork for about a year now offering both webcam and phone. Now I'm spending some time abroad and want to be able to offer both services but connection charges for being abroad prevent me from being able to use the phone.

Does anyone know if I can use a Skype number? I don't have one but as far as I understand they are landline numbers and cannot receive texts. To verify my phone last time I had to receive a text message and reply to it.

I'd be very grateful for any advice.
Thanks
