Does my DTAC phone have cancer?

[Thighlander]

It used to be that 60 thb would last three weeks. I came back and my number is still good, but the credits shrink even though I'm not making calls. Anyone else notice this? Is there a daily fee? Are those junk SMS costing me money. Should I switch. Seems like about 9 thb per day just disappears. Tried to block a few of the ads and that didn't seem to work...."block by address" Any clues? Thanks!

With AIS I can log on to my prepaid phone via their web site and list the numbers I called in the last month and what I paid/call. I am sure DTAC offer the same service ---> https://mydtac.dtac.co.th/EserviceLogin/Login?page=N

check to make sure your phone is not allowing mobile data. This will drain your credit fast

That is the common issue with unknown drain. For example, push notifications in themselves do not cost but they do use data. I have mobile Data (APN) disabled all the time as I use wireless most of the time and data in an emergency.

If your plan does not include data, you pay through the nose for it.

Either turn it off or get a plan that fits your wallet and usage, and that reduces speed when you've used your bandwidth, rather than charging you extra.

I've never visited any website with it. Don't even know if I can. Very basic Samsung, doesn't even have a camera. I don't have an account with DTAC, I just add time at 7-11 or any phone shop. I'll take another look through the set-up.
