Mobile Number Portability Request Rejected Repeatedly? Action Plan
You sent the PORT SMS, gave the code to a new operator, and waited — only to get a rejection message again. A repeatedly rejected mobile number portability (MNP) request almost always comes down to one fixable problem: an unpaid due, a wrong or expired code, or a name that does not match the SIM owner. This guide shows you how to read the rejection, fix the exact cause, and escalate properly if your operator keeps blocking you.

Quick answer
A port fails for one specific reason, named in the rejection SMS. Read that reason first. Generate a fresh Unique Porting Code (UPC) by sending PORT <your 10-digit number> to 1900. Clear any outstanding bill and keep the paid proof. Make sure the SIM is in your own name with matching KYC. Then re-apply. If the operator still rejects you despite a clean account, escalate in writing to its nodal officer, then the appellate authority, and finally the consumer commission. RTI only helps where a public authority holds records.
Who this guide is for
This guide is for any mobile user in India whose request to keep their number while switching operators has been rejected more than once. Mobile Number Portability (MNP) lets you move your number from one operator to another, prepaid or postpaid, without changing the number. When it works, it is smooth. When it keeps failing, it is almost always a single unresolved flag on your account. This guide is useful if:
- You keep getting a rejection SMS within a day or two of applying with the new operator.
- You are told there are "outstanding dues" even though you believe you have paid.
- Your port is blocked because the SIM is not in your own name, or the KYC details do not match.
- Your code keeps "expiring" before the new operator can use it.
- You ported recently and a new port is being refused.
Most telecom services in India are run by private companies. That matters for your remedies: your main route is the operator's own grievance ladder and, if that fails, the consumer commission — not a complaint that an outsider can force on a private firm. We explain where RTI does and does not fit later in this guide.
If your underlying problem is a SIM ownership or KYC mismatch that also blocks an eSIM swap, read the companion guide on SIM ownership and KYC mismatch in porting and eSIM replacement.
What you can do this weekend
Friday evening
Find the exact rejection reason. Open the SMS the new operator sent you when the port failed. It usually states a short reason — outstanding dues, code mismatch, minimum stay period not met, contractual obligation, or KYC mismatch. Write that reason down word for word. Everything you do next depends on it.
If you cannot find the SMS, call the new operator's customer care and ask for the rejection reason and the date. Note the docket or complaint number they give you. Then call your current operator and ask the same. The two operators sometimes describe the same block differently, so collect both versions.
Generate a fresh Unique Porting Code. Send an SMS reading PORT <space> your 10-digit mobile number to 1900 from the number you want to port. You will get back an 8-character UPC with a short validity. Note the exact expiry shown in the reply, because an expired code is one of the most common causes of repeat rejection.
Saturday
Clear the money question. Log in to your current operator's app or website and check for any pending bill, instalment, or device-on-EMI balance. For postpaid numbers, even a small unbilled or part-billed amount can trigger a dues rejection. Pay any balance and download the payment receipt and a statement showing zero outstanding.
Check ownership and KYC. Confirm the SIM is registered in your own name and that the name, ID, and address on the operator's records match the documents you will give the new operator. If the SIM is in a parent's, spouse's, or company's name, a straight port will be rejected — you need an ownership change or fresh KYC with the current operator first.
Check timing rules. A number generally has to stay on a network for a minimum period before it can be ported, and there is a lock-in after each successful port before you can port again. If you ported recently, you may simply have to wait out the lock-in. Confirm the current periods on the official TRAI pages rather than relying on a forum post.
Sunday
Assemble a single clean file: your latest paid bill or zero-balance statement, the payment receipt, your ID and address proof, a screenshot of the fresh UPC with its expiry, and the rejection SMS. This is the bundle you will attach to any complaint.
Re-apply with the new operator using the fresh UPC, ideally early in its validity window so it does not lapse before processing. If you have already been rejected for the same wrong reason more than once, do not just re-apply blindly — draft the complaint in this guide so you are ready to escalate on Monday if it fails again.
Note your dates. Keep a simple log: date of each port attempt, the UPC used, the rejection reason, and every docket number. A clear timeline is what makes an escalation succeed.
Documents and evidence checklist
| Document | What it proves | Where to get it |
|---|---|---|
| Rejection SMS / message from the new operator | The exact stated reason and date of rejection | Your phone's messages from the recipient operator |
| Fresh Unique Porting Code (UPC) with expiry | A valid, unexpired code was offered for the port | SMS PORT <number> to 1900 from the number being ported |
| Latest bill / statement showing zero outstanding | No dues are pending on the number | Current operator's app or self-care portal |
| Payment receipt / transaction reference | You actually paid the disputed amount and when | Bank or UPI app statement; operator payment history |
| Identity and address proof (KYC) | Your details match the SIM owner's records | Aadhaar, passport, voter ID, or other accepted proof |
| Ownership change / company authorisation (if relevant) | You are the lawful owner where the SIM was in another name | Current operator's ownership-change process; company letter |
| Death certificate and legal heir proof (if relevant) | Right to take over a deceased person's number before porting | Municipal authority; revenue or court office |
| Complaint docket numbers from customer care | You raised the issue and gave the operator a chance to fix it | Each call or chat with customer care of both operators |
| Port-attempt log (your own) | The pattern of repeated rejection for the same reason | A simple note you maintain with dates and reasons |
Step-by-step action plan
Step 1 — Read the rejection reason exactly
Do not guess. A port can be rejected for several different reasons, and each has a different fix. Read the rejection SMS carefully and write down the precise wording. If the message is vague, call the new operator and ask them to read out the reason code or note recorded in their system, and ask the same of your current operator. Record the docket numbers. The whole rest of the process is about fixing the one named reason — not re-trying the same thing and hoping.
Step 2 — Generate a fresh, valid UPC
The Unique Porting Code is central to MNP. Send PORT <your 10-digit number> to 1900 from the number you want to port. The operator replies with an 8-character code and an expiry date. Two things matter: the code must be unexpired when the new operator processes it, and it must be the code for the correct number. Many repeat rejections are simply lapsed codes. If yours keeps expiring, generate it just before you submit the new application, not days in advance. If you cannot generate a UPC at all, that itself may signal an unresolved dues or contract flag on the number — go to Step 3.
Step 3 — Clear dues and keep proof
For postpaid numbers, the donor operator can refuse a port where any amount is unpaid, including a part-billed cycle or a device instalment. Log in to your operator's self-care portal, settle any balance, and download both the payment receipt and a statement showing zero outstanding. If you have already paid but the system still shows dues, raise a customer-care complaint, get a docket number, and ask them to update the dues status. Keep the proof — you will attach it to every later escalation. For prepaid numbers, dues are rarely the issue, so focus on the UPC and KYC instead.
Step 4 — Confirm SIM ownership and KYC match
A port carries the number to a new operator but keeps the same owner. It is not a way to change whose name the number is in. If the SIM is registered to a parent, spouse, employer, or a deceased relative, the new operator's KYC will not match the application and the port fails. Fix the ownership first with the current operator: complete an ownership change or fresh KYC supported by the right documents — for a company number, an authorisation letter; for a deceased owner, a death certificate and legal heir proof. Only after the records show your name should you raise the port. For background on why old numbers carry hidden risk, see mobile number recycled and old account risk.
Step 5 — Check timing and contract conditions
A number usually must stay on a network for a minimum period before it can move, and after each successful port there is a lock-in before you can port again. Corporate or bulk connections, special tariff contracts, and bundled-device plans can also carry obligations that block a port until they end. If your rejection reason is "contractual obligation" or "minimum period not met," confirm the relevant period and condition with your operator, and check the current rules on the official TRAI pages. Sometimes the only fix is to wait out the period — re-applying earlier will keep failing.
Step 6 — Re-apply cleanly, then escalate if it fails again
With the named reason fixed, a fresh UPC, and proof in hand, submit the port again. If it is accepted, watch for the scheduled cut-over window when the old SIM deactivates and the new one activates. If it is rejected again for a reason you have already resolved, stop re-trying and move to a written complaint. For the full porting procedure end to end, see how to port your mobile number (MNP) in 2026.
Step 7 — Use the operator's grievance ladder
Telecom operators are required to run a structured grievance system: a customer-care complaint with a docket number first, then a nodal officer, then an appellate authority. Send a written complaint (email or the operator's complaint form) describing the repeated rejection, the reason you have already fixed, and attach your proof. Quote your earlier docket numbers. Ask for a specific outcome: clear the wrong flag and allow the port. If the nodal officer does not resolve it within a reasonable time, escalate in writing to the appellate authority of that operator.
Step 8 — Escalate to the regulator and consumer route
If the operator's appellate authority still fails you, two channels remain. You can report a systemic or service-quality problem to the regulator through the official TRAI channels, keeping in mind that TRAI sets rules rather than settling individual bills. For a genuine deficiency in service where you met every condition and paid, the consumer commission is the effective forum — see how to file a consumer court complaint in India. Carry your full evidence bundle and timeline to whichever route you choose.

Escalation ladder
| Stage | Action | Forum / Destination | Target outcome |
|---|---|---|---|
| 1 | Raise a complaint and get a docket number | Customer care of the current (donor) operator and the new (recipient) operator | Wrong flag identified and a docket recorded |
| 2 | Written complaint with proof of paid dues and fresh UPC | Nodal officer of the operator (details on the operator's website) | Dues / mismatch cleared; port allowed |
| 3 | Appeal if the nodal officer does not resolve it | Appellate authority of the operator | Final operator-level decision in writing |
| 4 | Report a systemic or service-quality issue | TRAI (trai.gov.in) and the National Consumer Helpline | Regulatory record of the problem |
| 5 | File a deficiency-of-service complaint with evidence | Consumer commission (district / state) | Direction to complete the port and any compensation |
| 6 | RTI only where a public authority holds records | CPIO of the relevant government department / regulator (not a private operator) | Records on a policy or government-service matter |

When RTI can help
The Right to Information Act, 2005 applies to public authorities — government departments, regulators, and public-sector bodies — not to private companies. In a porting dispute, that limits where RTI is useful, but it is not useless. RTI can help in these specific situations:
- Government as your service provider: If your mobile service is provided by a public-sector telecom undertaking, that body is a public authority. You can file an RTI with its Central Public Information Officer (CPIO) asking for records relating to your number, such as the recorded rejection reason and the noting on your porting request.
- Policy and systemic information: You can seek records from the relevant government department or regulator on porting rules, instructions issued to operators, or how a particular category of complaint is handled — useful when you suspect a systemic block rather than a one-off error.
- Status of your own representation to a public authority: If you have escalated to a government grievance channel and heard nothing, RTI can be used to ask for the status and any decision on your representation.
To file an RTI online, see our step-by-step RTI filing guide. If a public authority does not answer within the time allowed, use the first appeal under RTI Section 19, and for the full appeal path read the RTI first and second appeal guide. For escalating government grievances alongside RTI, see CPGRAMS and RTI together. For a worked example on porting specifically, see using RTI with TRAI on mobile portability. For deeper strategy, The RTI Playbook covers how to use RTI in regulated-service disputes.
When RTI will not help
RTI has clear limits in a porting dispute, and it is important not to waste time on the wrong tool:
- Private telecom operators are not covered: You cannot file an RTI against a private mobile operator to demand its internal records or the reason for your rejection. Their grievance ladder — customer care, nodal officer, appellate authority — is your route there.
- RTI cannot force the port to happen: RTI gives you information, not a substantive order. Only the operator can complete the port, and only the consumer commission can order it to. RTI supports your case; it does not replace the complaint.
- It is slower than the grievance ladder: An RTI takes time to be answered, while a docketed customer-care complaint and a nodal-officer escalation are usually faster for getting a wrong flag cleared.
Common mistakes to avoid
- Re-applying without fixing the reason: The single biggest mistake is sending the same request again after a rejection without changing anything. Identify the named reason and fix that exact item first.
- Letting the UPC expire: A code has a short validity. Generate it just before you submit the new application, not days ahead, so it does not lapse during processing.
- Assuming "paid" means "cleared": A payment can take time to reflect, and a part-billed cycle or device instalment can still show as dues. Always confirm a zero-balance statement and keep the receipt.
- Trying to change ownership through a port: A port keeps the same owner. If the SIM is in another person's name, do the ownership change or fresh KYC first, then port.
- Porting inside a lock-in: If you ported recently, a fresh port may be blocked until the lock-in ends. Check the period instead of repeatedly failing.
- Not collecting docket numbers: Without a paper trail of complaints and dockets, an escalation has nothing to stand on. Note every reference number from every call.
- Filing an RTI against a private operator: RTI does not apply to private companies. Sending one only delays you; use the operator's grievance ladder and the consumer route.
- Ignoring the cut-over window: Even a successful port has a short window when the old SIM stops and the new one starts. Do not panic if the line is briefly inactive during the scheduled change.
If the rejection is really a SIM ownership or KYC problem rather than dues, the detailed fix is in SIM ownership and KYC mismatch in porting and eSIM replacement.

Frequently asked questions
Why does my mobile number porting request keep getting rejected?
The most common reasons are an outstanding bill on a postpaid number, the number being on the network for less than the minimum period, an expired or wrong Unique Porting Code (UPC), a name or KYC mismatch between the SIM owner and the porting application, a pending contractual obligation or active corporate plan, or a port request raised within the lock-in of a previous port. Find the exact reason from the rejection SMS and fix that specific item before re-applying.
What is a UPC and how do I get one for porting?
UPC stands for Unique Porting Code. You generate it by sending an SMS in the format PORT space your 10-digit number to 1900 from the number you want to port. The operator replies with an 8-character code that has a limited validity, usually a few days. You must give a valid, unexpired UPC to the new operator. If you wait too long, the code lapses and the request is rejected; just generate a fresh one.
I have already paid my bill but porting is still rejected for dues. What do I do?
Keep the payment proof, transaction reference, and a paid bill or statement showing a zero balance. Call your current operator's customer care, raise a complaint, and get a docket or complaint number. Ask them to update the dues status in the porting system. If they still block the port, escalate in writing to the operator's nodal officer and then the appellate authority, attaching the payment proof. The dues flag must be cleared at the donor operator's end before the new operator can complete the port.
The SIM is in my late father's or my company's name. Can I still port it to my name?
A port keeps the same owner; it does not change ownership. If you want the number in a different name, you usually need an ownership change or a fresh KYC with the current operator first, supported by documents such as a death certificate and legal heir proof, or a company authorisation letter. Complete the ownership change, then raise the port. Porting under a name that does not match the operator's KYC records will be rejected for a mismatch.
How do I complain to TRAI if my porting keeps failing?
First exhaust your operator's own complaint system: customer care, then nodal officer, then appellate authority. TRAI does not resolve individual billing or service complaints directly, but you can register the issue on the TRAI DND or complaint channels and report a systemic problem. For a service deficiency where you have paid and met all conditions, the consumer route under the operator's grievance process and, if needed, the consumer commission, is the effective remedy.
Can RTI help me find out why my porting was rejected?
RTI applies to public authorities, not to private telecom companies. You cannot use RTI to ask a private operator for its records. RTI can help only where a public authority holds relevant records, for example the licensor or regulator on a policy or systemic matter, or a government department if it is your service provider. For a rejection by a private operator, your route is the operator's grievance ladder and the consumer commission, not RTI.
How long should a successful port take once accepted?
Once a valid request is accepted and there is no rejection, porting within the same telecom circle is generally completed in a few working days, with porting between circles taking a little longer. There is a short scheduled cut-over window when your old SIM stops and the new SIM activates. Exact timelines are set by the regulator and can change, so confirm the current period on the official TRAI or operator pages.
