AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
A UK banking app normally keeps working while you visit Nigeria, and the payment itself goes out the same way it would from London. What trips people up is authentication: if your bank sends one-time codes by text to your UK number, you need that SIM reachable abroad, or another approval method set up before you fly. The FCA expects banks to offer authentication methods that do not rely on a mobile phone, so ask your bank what it offers before you travel.
You land in Lagos for a month. The electricity token is low, your mother's rent is due, and a cousin's school fees need topping up. You open the same UK app you use at home. Most of the time it simply works. The problems, when they come, are rarely about Nigeria blocking anything; they are about your bank checking that the person tapping the screen is really you.
Does the app work in Nigeria at all?
For the UK banks and apps we checked, travelling does not switch the account off. Starling's travel page says there is "no need to tell us you're heading away" and lets you lock your card in the app with a tap (data correct as of 19 October 2026). Monzo's help pages on fees abroad treat spending and cash withdrawals outside the EEA as normal use, with limits. Your app's own terms decide whether you can keep using it if you move abroad for good; a visit is a different matter from changing where you live.
Sending money to a Nigerian account from the app is the same transaction whether you press the button in Peckham or in Port Harcourt. Monzo, for example, sends NGN as a local transfer over NIBSS Instant Payments (NIP) through partner banks, with up to ₦95,000,000 per transfer, most payments arriving within seconds and nearly all within 6 hours, according to its help page. See how Monzo's Nigeria transfers work.
The real risk: security codes
UK payment firms must use strong customer authentication when you start an electronic payment, sign in to your account online, or do anything remotely that may carry a fraud risk, unless an exemption applies. That is the FCA's description of the rules. In practice it means a code, a fingerprint, a face scan or an approval in the app.
The weak point is the text message. If your bank sends a one-time passcode to your UK number and that SIM is switched off, swapped for a Nigerian SIM, or out of roaming coverage, the payment stalls. The FCA says it expects firms to build methods "that work for all groups of consumers", including methods that do not rely on mobile phones. So there is usually another route, but you need to set it up before you are standing at the meter.
What to set up before you fly
- Check how your bank approves payments: in-app approval, a card reader, or an SMS code. If it is SMS, ask what the alternative is when you are abroad.
- Decide what happens to your UK SIM. Keeping it in a dual-SIM phone with roaming on lets texts arrive; check your network's roaming charges for Nigeria on its own page.
- Add the Nigerian payees you will need (landlord, school, family) while you are still at home, so you are not adding new payees from an unfamiliar connection.
- Make sure your app is updated and you know your passcode. A reinstall abroad can trigger a full re-verification.
- Save your bank's overseas contact number. A UK 0800 number may not connect from a Nigerian line.
Data and Wi-Fi
Your app needs a connection, not a UK one. Hotel Wi-Fi, a Nigerian data SIM or an eSIM all work. Starling's travel page offers eSIMs for mobile data in 130 countries, set up in the app. Public Wi-Fi is fine for an app that encrypts its traffic, but avoid typing banking passwords into browser pages on shared networks.
Paying bills in naira from a UK account
Bills in Nigeria are naira bills. From a UK app you have three broad ways to settle them:
| Route | What happens | Watch for |
|---|---|---|
| International transfer to the biller's or landlord's naira account | Pounds are converted to naira and paid into a Nigerian account | The exchange margin and any fee; the app shows them before you confirm |
| Card payment on a Nigerian website or POS | Your UK card is charged in naira and converted by the card scheme | Non-sterling fees: Barclays charges a 2.99% non-sterling transaction fee on debit card payments abroad; Monzo and Starling say card spending abroad is fee-free |
| Cash withdrawal at a Nigerian ATM | Naira cash, converted from your UK balance | Withdrawal limits and ATM owner charges; Monzo caps fee-free cash outside the EEA at £200 per 30 days on most accounts, 3% above that |
For electricity in particular, see paying for an electricity token from the UK. When a terminal asks whether to pay in pounds or naira, Starling's guidance is to choose the local currency, so your own provider does the conversion rather than the merchant's.
If something goes wrong in Nigeria
- Payment stuck on a code: use the in-app chat, which normally works over data without a UK SIM.
- Card blocked after a Nigerian payment: freeze and unfreeze from the app if your provider allows it, or call the overseas number you saved.
- Transfer sent but not credited: get the reference and see why a Nigerian bank may delay crediting a UK transfer.
Where Pryme fits
A Pryme Personal Account can be opened from any country and holds NGN, GBP, USD and EUR, each with local account details. If you keep a naira balance, bills in Nigeria are paid in naira without a conversion at the till; when you do convert, Swap shows the rate first and the fee on its own line before you approve. Pryme uses an authenticator app rather than SMS codes (security), which helps when your UK SIM is off. Naira deposits are held by a licensed Nigerian microfinance bank; outside Nigeria, Pryme's activities are carried out through regulated partners.
Questions people ask
Can I use my UK banking app in Nigeria?
Generally yes for a visit. The banks we checked, such as Starling, say you do not need to tell them before you travel. Check your own bank's terms if you are moving abroad rather than visiting.
Why am I not getting my bank's OTP in Nigeria?
Usually because the code is sent by text to a UK SIM that is off, swapped out or not roaming. Ask your bank for an alternative method; the FCA expects firms to offer options that do not rely on a mobile phone.
Is it cheaper to pay a naira bill by card or by transfer from the UK?
It depends on your provider. Compare the card's non-sterling fee and rate with the transfer's fee and margin; the app shows the transfer cost before you confirm.
How much naira can I withdraw with a UK card in Nigeria?
Limits are set by your provider and the ATM. Monzo, for example, gives £200 of fee-free cash per 30 days outside the EEA on most accounts, then charges 3%.
