Exactly that. Blocks mobile internet on the provider (AIS) side independent of any phone settings.

300 Baht: AIS always eats up to 10 Baht. Then sends an SMS message about it (she should see that!). And then continues with a very low data rate for the rest of 24h.

Incorrect. It might use up to 49 baht per day...then slow down for the rest of that day. But you are quoting an out of date post, because someone decided to bump the thread.....three months later.

You need to call 1175 to report it as a fault, if it is a fault. Then technicians can get involved.

already did that a month back ....  all they did was go out and check the signal strength by plugging in the laptop at the rooftop site ...  they probably adjusted nothing and consider it acceptable.  I will put up with it until I can't stand it no more then I'll go back to them .... but I know what the AIS shop is like.... if you pay 1500/m you'll get a reasonable service with no buffering .... if you pay 200/m you'll get a service that they consider acceptable for that price.    That's my assessment and I think it's correct.

It isn't correct, as I am also running unlimited 10 & 20 Mbps SIMs. So I have relevant experience.
