It is possible that you have upgraded to a new mobile phone, which is why Google Pay limits the amount of money you can send to a maximum of 5,000 rupees. You are only allowed to transmit a maximum of Rs 5,000 if you have changed any of the following: your phone, mobile number, or UPI PIN. Having said that, the restriction is only applicable for the first twenty-four hours. You may have already hit the daily maximum transaction limit or the number of maximum transactions that are allowed per day for your bank, which is another reason why you are unable to transfer more than Rs. 5,000 using Google Pay.
You are able to send up to one lakh rupees using Google Pay in a single day. In addition, the maximum number of times that one can send money using any UPI application in a single day is 10.
