Mobile Number Portability (MNP) in Nepal: Keep Your Number When Switching NTC and Ncell

Mobile Number Portability (MNP) is a facility that lets a mobile subscriber move from one telecom operator to another while keeping the exact same phone number. Instead of surrendering a number that friends, family, banks, and businesses already have saved, a Nepal Telecom (NTC) user could switch to Ncell, or an Ncell user could switch to NTC, and continue receiving calls and SMS on the number they have always used. The number becomes portable; the operator behind it changes.

Today, changing operators in Nepal means buying a fresh SIM with a brand-new number and then notifying every contact, bank, and online account of the change. That friction locks many users into a network even when they are unhappy with its coverage, data prices, or customer service. MNP removes that lock-in: the number stays, so the barrier to switching drops, and operators must compete harder on quality and price to retain customers.

Because keeping your number while changing network is a long-awaited convenience, public interest spikes every time the Nepal Telecommunications Authority (NTA) issues a fresh announcement. Search interest in phrases such as 'mobile number portability nepal' and 'change network keep number' rises with each notice, which is exactly why understanding the rules, eligibility, and honest status of MNP matters before you plan a switch.

MNP in Nepal is built on the Mobile Number Portability Regulation, 2078 BS, prepared by the Nepal Telecommunications Authority (NTA), the country's telecom regulator. The NTA tabled the draft regulation in November 2021 (2078 BS) and invited comments from the licensed operators before finalising the framework. The regulation defines who is eligible, how a port is requested, how operators must cooperate, and how the neutral porting infrastructure is to be run.

A central design choice in the regulation is that porting is 'recipient-led.' This means the subscriber approaches the operator they want to move to (the recipient), not the operator they are leaving (the donor). The recipient operator initiates and drives the request on the customer's behalf, which is the model most modern MNP systems around the world use because it keeps the switching customer's experience simple.

The regulation also anticipates that MNP cannot be run by the operators alone, because a neutral party is needed to route ported numbers correctly. It therefore provides for a third-party clearing house, commonly described as a Number Portability Clearing (NPC) House or 'Number Portability House,' to manage porting requests and the central routing database. Whether this house operates directly under NTA supervision or as an independent entity following NTA directives is a detail the authority has been finalising.

Eligibility is defined so that only genuine, active, and unencumbered numbers can be moved. The headline rule is the active-use period: a subscriber must have used the number for a minimum period before it can be ported. Reporting on the regulation consistently cites this minimum as 90 days, meaning a freshly bought SIM cannot be immediately ported to a rival network.

Beyond the active-use period, the subscriber must clear all obligations to the current (donor) operator. That means no outstanding dues, no unpaid postpaid bills, and no pending liabilities. The number must also be live and in good standing at the time of the request, not blocked, suspended, or halted, and it must be correctly registered in the donor operator's SIM database with owner details that match the applicant's identity documents.

Because Nepal enforces biometric and identity-verified SIM registration, the identity on record must match the person requesting the port. This protects against someone porting away a number that does not belong to them. The applicant typically self-declares that the number is genuinely theirs and has not been stolen, misused, or used for any unauthorised purpose.

Under the recipient-led model, you begin at the operator you want to join. You visit an authorised outlet or service centre of the recipient operator (for example, an Ncell centre if you are leaving NTC, or an NTC centre if you are leaving Ncell) and tell the staff you want to port your existing number to their network while keeping it. You will complete a porting application form and hand over the required documents.

The recipient operator then registers the request through the central clearing house, which coordinates with your current (donor) operator to verify eligibility, dues status, and identity. A confirmation or one-time-password (OTP) step is used to prove that the request genuinely comes from the number's owner, which is why your existing number must still be reachable during the process. Once verified, the number is scheduled to be transferred to the new operator's network.

Crucially, your existing service keeps running until the port actually completes, so you are not left disconnected during the review. At the moment of the actual switch, there is typically a brief service interruption while the number is handed over between networks, after which your new operator's SIM becomes active on the same number. Reported timelines for completion are indicative and range from a day or two in efficient implementations to several working days; you should confirm the exact window with the operator when MNP goes fully live.

You should carry a valid government-issued identity document that matches the SIM registration, such as your citizenship certificate or National ID card, plus the SIM you want to port. For foreign nationals holding a Nepali number, a passport is the standard identity document. The self-declaration form, confirming the number is yours and free of misuse, is completed at the outlet.

MNP is expected to carry a modest charge rather than being free, and the regulation is designed so that the porting-related messages sent by the clearing house cannot be billed to the user by operators. Exact port fees, and whether a new SIM card charge applies, will be set when the service launches commercially; treat any specific rupee figure circulating before launch as unconfirmed. Historically, regulators in many countries have pushed these fees low or to zero to encourage competition.

Be aware of what does not travel with your number. Porting moves only the phone number itself, not your balance or plan. Any remaining prepaid balance, bonus data, loyalty points, or operator-specific offers on the donor network are generally forfeited, and you move onto the recipient operator's tariffs. Plan your switch when your balance is low, and read the recipient operator's current plans before you commit.

Not every request will succeed, and the regulation builds in checks that can lead to rejection. The most common reasons trace directly back to the eligibility rules: the number has not met the minimum active-use period, there are unpaid dues or unresolved bills on the donor network, or the number is currently blocked, suspended, or otherwise not in good standing.

Identity mismatches are another frequent cause. If the details registered against the SIM do not match the documents and identity of the person requesting the port, the request will be declined to prevent fraudulent transfers. A number reported as lost, stolen, or under legal or investigative hold will likewise be blocked from porting.

Procedural failures can also stop a port, such as an incomplete or incorrect application form, a missing self-declaration, or failure to complete the OTP or confirmation step within the allowed window. If a request is rejected, the fix is usually to clear dues, correct your registration details, wait out the active-use period, or re-submit a complete application.

As of mid-2026, Nepal has the regulatory framework for MNP in place, but a full commercial launch with a firm public start date has not been confirmed. The Mobile Number Portability Regulation, 2078 BS exists, the NTA has signalled its intent to implement the service through a third-party clearing house, but the supporting infrastructure and appointment of the porting house have taken time. NTA officials had earlier indicated that implementation could take at least six months after the draft was approved because central systems must be built and integrated with the operators.

The operator landscape has also changed since the regulation was drafted. When the 2078 draft was tabled, Nepal had three mobile operators, Nepal Telecom (NTC), Ncell, and Smart Telecom (Smart Cell). Smart Cell's licence was subsequently revoked around 2023, leaving NTC and Ncell as the two active mobile network operators. In practice, then, MNP for most users means the ability to move between NTC and Ncell while keeping the same number.

Because dates and details around MNP have shifted repeatedly with each NTA announcement, treat every specific timeline as provisional until the authority and operators confirm a live launch. Before you attempt to switch, verify the current status directly with NTA or with an NTC or Ncell service centre. This article states durable facts from the regulation and honestly flags what is not yet finalised, rather than promising a launch date that has not been officially set.
