Guys Im new on android always had the normal mobiles, I always had pay as you go and did not need more than £5 a mounth because when I am at home I send sms on my computer (esemes.co.uk) for free. I would like to know if there is an app that can send sms for free to any mobiles not just android (Whatsapp). Im going to top up £5 monthly and get 500mb.
Thank you.

Go with Google Voice for free sms =). Then you can chat from phone and computer all from same number easily (and free calling)

Whatsapp - free sms, photo...

Viber and Tango work too
