VoIP and international calls to Nigeria terminate almost entirely on mobile networks, mainly MTN and Airtel, and the price of inbound international minutes is shaped by a termination rate that the regulator sets in US dollars. Buyers usually choose between CLI and non-CLI routes per operator, and the main risk to watch is call masking (international calls delivered as local ones).
Rules last checked: October 2026.
Regulator and operators
The telecom regulator is the Nigerian Communications Commission (NCC). Four mobile network operators carry nearly all traffic:
- MTN: the largest, with just over half of all subscriptions according to NCC data for mid-2026.
- Airtel: the second network, with roughly a third of subscriptions.
- Globacom (Glo): the third network.
- T2 (formerly 9mobile): a small share of the market.
As of mid-2026 the NCC reported about 192 million subscriptions, almost all of them mobile. Fixed lines are a very small part of the market, so a Nigeria rate deck is in practice a mobile deck split by operator. Mobile numbers start with ranges such as 70, 80, 81, 90 and 91 after the country code 234, and Nigeria has mobile number portability, so the prefix alone does not always tell you the current network. See mobile number portability and call routing.
How international calls are priced
Since 2022 the NCC has set the mobile international termination rate (ITR) in US dollars, so that Nigerian operators are protected from naira devaluation. The 2022 amended determination replaced the earlier floor with a fixed rate and gave Nigerian transit and international data access (IDA) operators a set discount. As of 2026 the NCC is running a broad review of wholesale charges that includes international termination, so check for changes before you build a long term price.
What this means for buyers:
- A legal, direct route has a cost floor set by regulation, so very low offers deserve questions.
- Differences between carriers come mostly from who holds the interconnect (operator owned international carriers, licensed transit carriers or resellers) and from CLI handling, not from the termination charge itself.
- Operator mix matters: a route that is good on MTN may be weaker on Glo or T2. Ask for per operator breakouts rather than a single "Nigeria mobile" price. More in VoIP breakouts.
CLI, call masking and SIM boxes
The gap between the international and local termination charge has long encouraged two related practices: SIM boxing (terminating international calls through local SIM cards) and call masking (presenting an international call with a local number so it is billed as local). The NCC treats both as violations and has suspended interconnect licences over them in the past. Its NIN-SIM linkage rules and its 2025 campaign against pre-registered SIM cards are also aimed at these practices.
For a buyer this matters in two ways. First, a "local CLI" offer to Nigeria at a price well below the regulated level is a red flag: the calls may be leaving through a SIM box, which brings short calls, poor audio and sudden blocking. Second, if you need your real caller ID delivered, test it with a CLI delivery test before you send volume. Background on the fraud side is in SIM box bypass fraud.
What buyers usually ask for
| Request | Why it matters for Nigeria |
|---|---|
| Breakout per operator (MTN, Airtel, Glo, T2) | Quality and price vary by network; a blended rate hides weak operators |
| CLI or non-CLI | Conversational and diaspora traffic usually needs CLI; see CLI vs non-CLI routes |
| Traffic type stated up front | Call center and dialer traffic is accepted on fewer routes |
| ASR and ACD in line with the traffic | Very short ACD or answer rates that look too good can point to bypass or false answer; see ASR, ACD and PDD |
What drives the price
The regulated dollar termination rate sets the base. On top of that come the transit layer (how many carriers sit between you and the Nigerian network), the CLI type, the operator, the billing increment and payment terms. Exchange rate swings in the naira do not move the ITR directly because it is set in dollars, but they do affect local costs and the size of the bypass incentive.

Getting a route
You can see the destination page for VoIP termination to Nigeria and, if you also send messages, A2P SMS to Nigeria together with the Nigeria sender ID and DND rules. Tell us the operators, CLI type, traffic type and expected volume, and we source the route from our carriers and manage it through our VoIP termination service. Request a Nigeria voice route.
Frequently asked questions
Is VoIP legal in Nigeria?
Carrying international calls into Nigeria is legal through licensed operators and interconnects regulated by the NCC. What the NCC treats as violations are SIM boxing, where international calls are terminated through local SIM cards, and call masking, where an international call is presented with a local number so that it is billed as local.
What is call masking in Nigeria?
Call masking means presenting an international call with a local Nigerian number so that it is billed as a local call instead of at the international termination rate. The NCC treats it as a violation and has suspended interconnect licences over it in the past. For buyers, a cheap local CLI offer to Nigeria is a red flag.
Who are the mobile operators in Nigeria?
Four mobile operators carry nearly all traffic: MTN, the largest with just over half of subscriptions, Airtel with roughly a third, Globacom (Glo), and T2, formerly 9mobile, with a small share. Fixed lines are a very small part of the market, so a Nigeria rate deck is in practice a mobile deck split by operator.
Why is the Nigeria termination rate set in dollars?
Since 2022 the NCC has set the mobile international termination rate in US dollars to protect Nigerian operators from naira devaluation. As a result, swings in the naira do not move the rate directly, though they change local costs and the incentive for bypass. The NCC is reviewing wholesale charges in 2026, so check for changes.
