@Prakash C Gupta Hello Sir, nice to get veterans in this forum. Welcome 🤗 And regarding your query on using UPI, there are two concerns :
1. UPI limit for applying in IPO is Rs 5L, you will be able to apply in retail as well as in sHNI but not in bHNI
2. Understand from some members that SBI does not allow transaction over Rs 1L in UPI mode.
Suggest use other platform like Gpay or Phonepe by linking your bank accounts for hassle-free UPI transaction with proper mandate.
Best Wishes 💐
