My "Wife to be" is having problems sending international texts as she

says DTAC have prevented this, I had a similar problem in UK with vodafone

but sorted now.

Is anyone aware of this, and will she have to change to another service provider?

Any advice would be much appreciated, thanks.

No such problem with HAPPYDPROMPT, the prepaid arm of DTAC. Does she have bills or does she buy the scratch cards?

I have no idea about the billed service, as that could be due to her not paying the bill.

With HAPPYDPROMPT, the International SMS is only three baht per message.

To send free text messages to her, use this utility(you have to register online first); https://sonic2.tac.co.th/bp3/bin/Index?lang=E

or

btw, make certain that she is using the correct configuration for sending text messages; ie +447*********
