Can you help?

Got this personal shopper enquiry in:

I’m looking for international texting. I’m in canada and would be texting to indonesia. i tried smstoindo it worked fine then when i bought more credits, somehow people i’m texting to were unable to receive the messages. I inquired them about it but they just said that it was sent. Anyways i’m looking for another suplier if possible unlimited texting or a cheap provider because i text internationally quite a bit. thank you so much for your time and work and its greatly appreciated.

Can you help or recommend? 🙂
