Hello everyone on Hamari Vani. I warmly welcome all the listeners and members. My name is Shatrudhan from Rajpur, Chhattisgarh, and I am 100% visually impaired. I need some information. I activated Ultra Cash UPI by inserting my SIM card into someone's touchscreen phone. However, after two days, my Ultra Cash UPI stopped working. I would like to know the reason why it was deactivated. If anyone knows the reason or the solution, please share the information on Hamari Vani or contact me.
