I get about 3 SMS a day from True mobile and they are in Thai. My mobile phone does not read Thai and I do not read Thai so it kind of pointless.
This has been going on for as long as I had the phone from True move and no lately they start calling me at 09.00 on Saturdays.
Listen True, I really do not want an answer machine call me in Thai at 09.00 in the morning. If you give me the private number of your SEO I will start calling him talking Swahili after the big company party and let’s see if he likes it.
I have not tried Dtac or AIS but let me know if they send you SMS or call you as well.
