How SunKing Payment Codes Work in Nigeria
SunKing does not have one single USSD code like *737# or *966#. Payment is done through your mobile money provider (OPay, PalmPay, MTN MoMo) or bank USSD to SunKing's merchant number. You then receive an unlock code by SMS which you type into your SunKing device using its keypad.
The most-searched code — the one that unlocks your device after paying — comes to you by SMS after payment. It is not the same code every time. It is a fresh code generated per payment.

How SunKing Pay-As-You-Go Actually Works
SunKing solar home systems in Nigeria use a pay-as-you-go (PAYG) model. Here is what that means in practice:
- You pay a small deposit upfront to receive the solar system — typically ₦5,000 to ₦25,000 depending on the model.
- You make regular payments — daily, weekly, or monthly — to keep the system unlocked and providing power.
- Each payment unlocks the system for a specific period. When that period expires, the device stops working until you pay again.
- After you complete all payments (usually 6 to 36 months depending on the plan), you own the system outright — no more payments, no more lock-outs.
- All payment activation is code-based — you enter unlock codes into the device manually after each payment (unless your device is app-linked).
Complete List of SunKing Codes and Channels
Below is every SunKing-related code and contact channel you need in Nigeria. Note: USSD codes for payment depend on your mobile money provider, not on SunKing directly. SunKing has one merchant number that these providers pay into.

How to Pay for SunKing (Step-by-Step)
The exact steps depend on your mobile money provider or bank, but the flow is the same across all of them:
- Check your registered phone number. Payments must come from — or reference — the phone number registered to your SunKing account. If you pay from a different number, the unlock code may not reach you.
- Open your mobile money app or dial your bank's USSD. OPay, PalmPay, MTN MoMo, or your bank's USSD code (like GTB *737#) all work.
- Select "Transfer" or "Send Money". On USSD, this is usually option 1 or 2 in the main menu.
- Enter SunKing's merchant number. This is the number your SunKing agent gave you. If you don't have it, call 0700-000-7864 before paying — do NOT guess.
- Enter the payment amount. The minimum depends on your plan — some plans require ₦100 daily, others require weekly or monthly minimums.
- Add your SunKing account phone number as reference/narration. This is critical — it tells SunKing which customer account to credit. Without it, your payment may not be linked to your device.
- Confirm and enter your PIN. Complete the transaction.
- Wait for the unlock code SMS. Usually within 5-30 minutes. Sometimes up to an hour during high-traffic periods. Check your SMS inbox including spam.
- Enter the unlock code on your device. See next section for how.
How to Enter Your Unlock Code on the SunKing Device
Once you receive the unlock code by SMS, you enter it directly on the SunKing device (not on your phone). The exact steps vary slightly by model, but the general process is:
- Find the button on your SunKing device. Most models have a small button labeled with a lock icon, a power symbol, or the word "MENU". On some models it's on the front, on others it's on the side of the control box.
- Press and hold the button until the display shows numbers or asks for a code. On some devices you need to press it twice quickly.
- Enter the unlock code using the number keys. The code is 8-12 digits — enter it exactly as received in the SMS. Take your time. If your device has no keypad, some models use volume/menu buttons to scroll through digits.
- Press ENTER or the confirmation button (usually a green button or the button labeled "OK").
- The device will beep, blink a light, or show "OK" / "ACTIVE" to confirm the code was accepted. If it shows an error, re-check the code — most errors are typing mistakes.
Common Problems and How to Fix Them
These are the most common SunKing payment/unlock issues Nigerian users report — and the fastest fixes:
❌ I paid but no unlock code arrived
First step: Wait a full hour and check your SMS thoroughly (including spam filters). Delays of 30-60 minutes are common during peak times.
If still no code after an hour: Call 0700-000-7864 with these ready: your payment reference number (from the mobile money confirmation SMS), your SunKing account phone number, and your device serial number (usually on a sticker on the device).
DO NOT make a second payment unless customer service specifically instructs you to. Doubling up on payments creates worse problems than being briefly offline.
❌ I typed the code but the device says "invalid"
Nine times out of ten, this is a typing mistake. Re-read the SMS carefully — 0 (zero) and O (letter O) look similar; 1 (one) and l (lowercase L) look similar; 5 and S look similar. Try again slowly.
If you're certain the code was correct: some unlock codes have a time limit (usually 24-48 hours from generation). If you waited too long, the code may have expired. Call customer service to have a new code generated.
❌ My device stopped working even though I paid recently
Check the SMS with your most recent unlock code — it will tell you the exact expiry date/time of that payment period. If today is past that date, you owe another payment.
If the payment period should still be active but the device won't turn on: this may be a hardware fault rather than a lock. Test in bright direct sunlight for 30 minutes to ensure it's charged, then try the power button. If still nothing, contact customer service — hardware faults are usually covered by SunKing's warranty if the device is under 2 years old.
❌ I sent payment to the wrong merchant number
Contact SunKing customer service immediately with your payment reference. In many cases they can trace the payment and either credit your account manually, or issue a refund. Success depends on how quickly you report it. Also contact your mobile money provider (OPay, PalmPay etc.) to report the misdirected transfer.
❌ Someone claiming to be from SunKing is asking for my unlock code
This is a scam. Real SunKing staff never need your unlock code — that code is generated for your device, not for their systems. Hang up, block the number, and report it to SunKing customer service at 0700-000-7864. Never send unlock codes, phone PINs, bank details, or payment amounts to callers claiming to be "helping" with your account.
❌ I want to stop making SunKing payments
If you stop paying, the device will lock and stop working once your current paid period expires. Payments already made are not refunded. If you're struggling financially, contact SunKing customer service before defaulting — they sometimes offer payment plans or hardship arrangements. If you've genuinely decided SunKing isn't right for you, see the alternatives section below.
If SunKing PAYG Isn't Working for You
SunKing works well for many Nigerian households, but the PAYG model isn't for everyone. Common reasons people move away from SunKing:
- Payment fatigue — the ongoing lock-outs feel like a subscription you can't escape
- Power capacity limitations — SunKing entry-level systems power lights and phone charging; they don't run fridges, TVs, or AC
- Total cost over the payment term — the sum of PAYG payments often exceeds outright-purchase prices for equivalent systems
- Wanting to own the system outright — with no risk of remote lock-out
If any of these apply, worth knowing what else is available in Nigeria:
Alternatives to SunKing PAYG
Own it outright: Solar panels, batteries, and inverters from Felicity, Luminous, or Su-Kam can be purchased directly — one payment, no ongoing lock-outs, you own it forever. Higher upfront cost, but often lower total cost of ownership than 24-36 months of SunKing payments.
Portable solar generators: All-in-one units (like the ones on our solar generator price list) work for renters, backup power, or partial-house coverage. No installation needed. One-time purchase.
Other PAYG providers: MTN Lumos operates a similar PAYG model with different pricing. Worth comparing if the PAYG structure suits you but SunKing specifically isn't working out.
