What is the best unlimited prepaid wireless service?

What is the best starhub prepaid service for roaming and for someone in the Philippines?

• I'm in the Philippines for a 3-month job that has connections with the company that i work with in Singapore. I want to continue using a Singaporean number because for my girlfriend it'd be rather expensive to text me if I got a number in the Philippines. SGD 0.50 a text to be exact. Anyway which prepaid service is best for roaming? Can I text to Singapore with the same rates as I would in Singapore because we would like to take advantage of using the Web SMS service so she wouldn't have to spend so much. What are the rates and tariffs? Thanks :]

• Answer:

  You are so considerate, wanting to save you girlfriend the S$0.50 per text while you pay more than S$0.50 per text received AND sent. My experience with WebSMS is that they will charge you according to a normal text rate. e.g. if you are roaming in Philippines and send a WebSMS, it is at the same rate as sending it from your handphone while roaming. So your idea will not save you any money. But I cannot remember the rates and tariffs anymore.
