I lost my GrabRewards and GrabPay Credits with my new mobile number
It's a good practice to link your Grab account to either Facebook or Google. This way, you can always have access to your Grab account even if you've changed to a new mobile number.
If you still have access to your old mobile number, please log in to your old mobile number first and change it to your new mobile number in the app.
Let us know, through the form below, if you do not have access to your old mobile number by providing both your old and new mobile number.
I receive error message "Please enter another mobile number" or "Invalid mobile number" when I try to change the mobile number.
You are getting this error message because the mobile number entered is already attached to an existing Grab account. If you are using a new mobile number and get any of these error messages, your number may have been recycled by your mobile operator.
Let us know, through the form below, if you are unable to change your phone number in-app by providing your old and new mobile number.
