Yes, you can have more than one Kaset Go account!
In order to have more than one account, you will need to have multiple devices and multiple mobile phone numbers to receive your One-Time Password (OTP) to register an account on Kaset Go.
As each account needs a registered phone number, you cannot share the same Kaset Go account across multiple devices. So if you have connected one account to your mobile phone number, you will not be able to connect a second account with that same mobile phone number.
