    Just to follow up on my previous comment, it should be international, but if you can help me find a free gateway here in the philippines, that would be appriciated! thanks!!

    Thanks for your comment.
    And if you are trying to make a professional website then i don’t suggest you to use free api’s.
    I suggest you to use orange free sms gateway, which is listed in 7′th number above. But orange only provides few credits for test and after that you should pay certain amount.
    But remember no free api can give you unlimited sms each day , they will have limit.
    Or you can also use wadja api , listed in 4′th in the article.

    And if you just plan to provide your service to peoples in US or India then you can try and zeepmobile listed in first and second.

    And I haven’t found any api from Philippines but i will search for one and update this article soon.

  8. subash says:

    @ tintincute

    I think the best one for what you are looking is Wadja.

    And I was searching for free sms api for Switzerland but didn’t found any ,
    any way I found this site:
    I just found that and Don’t know if they offer sms api or not, According to their site They give free 30 credits to test their service and some weekly free sms. But I am not sure if we can use SMS api with their service or not. After I get an account with them and test their service I will write about them here.
