India Mobile MNP After Return
Port Jio/Airtel keeping same number, TRAI 90-day rule, UPC code, and preserve UPI linkage.
The 60-second version
Mobile Number Portability (MNP) lets me switch operator keeping the same 10-digit number — critical for UPI, OTP, and Aadhaar-linked services.
Port before you cancel foreign SIM
My India number may still work on roaming — but post-return I port to best local operator for data pricing.
TRAI requires 90 days on current operator before port (unless corporate connection).
UPI, bank OTP, and GST portal use registered mobile — porting preserves number; do not cancel until port completes.

NRI-era prepaid?
Port works — must be active not expired.

No — MNP is India operators only.
Dual SIM phone?
Keep foreign SIM slot until India port done.
WhatsApp number?
Stays same if number unchanged.

Number same — no UIDAI update needed.

UPC regenerates — fix rejection reason.
The plan is only as good as the sequence.
Tax, banking, schools, shipping — they all have dependencies. A wrong order costs months and lakhs. Get it right.
