Sending credit to another phone via SMS ~ LB-69

I recall some people talking about being able to send phone credit to another phone via SMS and the advance is subtracted from your own credit or added to your bill.

I have Googled it but not found what I'm looking for. There is a service at www.aryty.com but it seems exclusively for the Philippines.

Have any of you guys heard about this or know of a service to 'top-up' your Thai friends' phones?

Question

Not exactly what I was looking for, but I found this, which may be of interest to some:

Was wondering about that myself i have a thai one to call sim card i need topping up up in uk dosent work how keep topping up so u dont lose u number ?

There's another thread about this gareth.

You don't lose the number, only the credit if the SIM goes unused.

so even if i not top and in 6 months time i can still use ?just top up when i there ?

hi dixon,

it used to be free off o2 mobiles but they stopped 0844 to many using it i expect but can still use off landline at 2p a min from uk to mobiles and landline in thailand.
