Best Way to Call Nigeria From the UK: Costs, Codes & Apps

Introduction

Finding the best way to call Nigeria from the UK takes more than knowing a country code — it means choosing the right method for your budget and your calling habits. Whether you're staying connected to family in Lagos or managing business contacts in Abuja, costs can swing from over 50p per minute on a standard carrier to under 3p on a VoIP app.

This guide covers the exact dialing format, Nigeria's country and area codes, a clear carrier-versus-VoIP rate breakdown, and the best calling window across time zones. Read every section and you'll know precisely how to call Nigeria from UK cheaply, clearly, and on the first try.

What You Need Before You Dial

The best way to call Nigeria from the UK depends on three factors working together: the UK exit code, Nigeria's country code, and the correctly formatted local number. Miss any one of them and the call either fails or reaches the wrong number entirely.

The UK international exit code is 00. Nigeria's country code is +234. Every Nigerian landline and mobile number starts with a leading zero in local format — that zero must always be removed before you add the number after the country code.

On any smartphone, replace 00 with the + symbol — press and hold the 0 key until + appears, then dial +234 followed by the number without its leading zero. Saving contacts this way means you can call Nigeria from UK or from anywhere else in the world without reformatting anything each time.

Exact Dialing Format to Call Nigeria From the UK

The quickest and most reliable best way to call Nigeria from the UK follows this format:

00 + 234 + area code (no leading 0) + subscriber number

Calling a Lagos Landline

Lagos landlines carry area code 01 locally. Drop the zero and dial: 00 234 1 XXX XXXX. A full number that reads 01 234 5678 in Lagos becomes 00 234 1 234 5678 from a UK handset.

Calling a Nigerian Mobile Number

Nigerian mobiles begin with 070, 080, 081, or 090 locally. Drop the leading zero and dial: 00 234 803 XXX XXXX. The local number 0803 456 7890 becomes 00 234 803 456 7890 from anywhere in the UK.

Nigeria Country Code and City Area Codes

Nigeria's country code is +234. Understanding which city code applies is central to the best way to call Nigeria from the UK consistently. Here are the area codes for Nigeria's most dialled cities:

Nigerian mobile operator prefixes (after removing the leading 0): MTN uses 803, 806, and 816; Airtel uses 802, 812, and 814; Glo uses 805 and 807. Always drop the initial 0 when you call Nigeria from UK. Our guide to dialing codes covers the same exit-code logic for international calls from the USA.

Step-by-Step: How to Call Nigeria From the UK

Follow these five steps for the best way to call Nigeria from the UK using any phone — mobile or landline:

Cost Comparison — UK Carrier Rates vs. Cheaper Alternatives

Cost is the key variable when identifying the best way to call Nigeria from the UK. Standard carrier rates to Nigeria sit at the high end of international calling:

A 15-minute call on BT costs roughly £8.25. That same conversation over Skype costs around 30p. If you call Nigeria from UK three or four times a week, switching to a VoIP service saves upwards of £100 a month compared to standard carrier billing — a difference that is immediate and measurable.

WhatsApp and Viber work well when both parties have reliable internet — free over Wi-Fi with good signal on both ends. When Nigerian data quality is inconsistent, a dedicated VoIP service or virtual number delivers more stable audio and far fewer dropped calls.

How to Get a Virtual Phone Number from CallMama

CallMama offers affordable virtual Nigerian phone numbers designed for anyone looking for the best way to call Nigeria from the UK without the carrier markup. A local Nigerian number from CallMama means your Lagos and Abuja contacts see a familiar digit string when you call — no surprise international prefixes on their screen, no charges on their end, and per-minute rates far below any standard UK tariff.

Best Times to Call Nigeria From the UK

Timing matters as much as dialing format. Nigeria runs on West Africa Time (WAT), UTC+1, year-round. The UK moves between GMT (UTC+0) from late October to late March and BST (UTC+1) from late March to late October.

The best way to call Nigeria from the UK in winter is to add one hour — 9:00 AM in London means 10:00 AM in Lagos. In summer, both clocks align and scheduling is straightforward. Aim to call Nigeria from UK between 8:00 AM and 6:00 PM UK time in winter to reach people during comfortable Nigerian hours.

Nigeria's business day runs roughly 8:00 AM to 5:00 PM WAT, so keep professional calls within that window. The NCC guidelines from Nigeria's national telecom regulator provide useful context for anyone setting up a formal business line to Nigeria.

Common Mistakes When Calling Nigeria From the UK

Even experienced international callers make these errors. Knowing them upfront is part of mastering the best way to call Nigeria from the UK every time.

Keeping the Leading Zero

The single most common mistake is dialling 00 234 01 XXX XXXX instead of 00 234 1 XXX XXXX. That extra zero routes the call incorrectly. Drop it every time — for both landlines and Nigerian mobile numbers.

Using the Wrong Exit Code

Some callers type 001 (the North American exit code) by habit. The UK exit code is 00, not 001. Using the wrong prefix means the call fails before it ever reaches Nigeria.

Calling at the Wrong Hour

Dialling at 11:00 PM UK time in winter puts a call through at midnight in Lagos. Use the time zone table above before you dial — especially for professional calls — and always aim for daytime Nigerian hours to avoid waking someone up.

Conclusion

The best way to call Nigeria from the UK comes down to three fundamentals: the correct dialing string (00 + 234 + area code without the leading zero + subscriber number), a clear-eyed look at what standard carriers charge versus what VoIP apps actually cost, and awareness of the one-hour winter time gap between the UK and Nigeria.

Carrier rates of 40–55p per minute make every long conversation expensive, while a VoIP service or virtual number brings that figure to under 3p.

Making every call Nigeria from UK as affordable as a local call is not complicated — it simply requires the right setup. Armed with everything in this guide, you have all you need to stay connected without overspending.
