I tried to add a few baht to DTAC using my phone and using my Windows 10 PC.

Both times resulted in no OTP (one time password) being received on my phone.

 

This was the attempt on Windows:

 

Entered my number (when doing this on the phone, the number is already there),

selected the amount and clicked "Refill":

 

Entered my VISA card details on the DTAC site:

 

Clicked "Submit", got sent to my bank's OTP authentication page and waited for the OTP on my phone:

 

The OTP never arrived. So hit "Cancel":

I did hit "Resend OTP" a couple of times. Each time the OTP Authentication page

refreshed with a different "Ref:" code.

 

Am I doing anything wrong? I used to get OTP's in the past,

but can't remember if I ever got one from DTAC.

Just to make it clear. The OTP is sent from Kasikorn bank.

And is the xxxxxx.... number registered at Kasikorn bank? (and you have the phone for this number at hand)

turn on the "flight mode" on your phone, wait for 5 minutes, turn off the flight mode.

or shutdown your phone, wait for 5 minutes, and power it on again.

I have had the same problem so I just top up the phone number from my BKK account to DTAC. 

Works for me but I will try fdsa method next time.

Yes, I had the phone in my hand... but I found the problem! The guy at DTAC in Tesco Lotus said "Oh, you have turned off the Internet!" Not his exact words, but that's what he meant.

So he clicked various things and the "4G" icon at the top of the screen started to show activity.

I got him to add some money to my account anyway, while I was there, so I haven't actually tried to "Refill" again, but I'm fairly sure it will work now.

If it doesn't, I'll post back here!
