TawagPinas works great. Currently it has the options for 300, 500 and 1000 peso loads for Smart and Globe that I've used. The do have 3 other options including Sun. The only reason why it's a 4 star rating and not 5 stars is I believe they should have a 50, 100 and 200 peso options too. Double check with you recipient that they got the load.

I can highly recommended to all my filipino friends using Tawag pinas network.because it's much cheaper and the signal is absolutely brilliant there is no nonsense drop calls or any signal interruption...this network is the best among the network I've used before!! Thank you so much for your marvellous network!

Better than phone cards! Clear conversation every time. Very low price per minute! Highly recommended for Philippine overseas calls!!!
