Roberts International is not in Monrovia at all: it sits beside the Firestone rubber plantation at Harbel in Margibi County, roughly 56 km from the capital, and the drive takes an hour on a good run and closer to ninety minutes with traffic or rain. That distance is what shapes the phone question here. Orange and Lonestar Cell MTN both have booths right outside the terminal exit, and both will hand over a free SIM against a passport, so a local line is easy to get. What an eSIM buys you is a phone that already works when you walk out of baggage claim into the evening heat, so you can find the driver holding your name, message your hotel or call your organisation's security desk before the long ride begins, rather than after a queue at the booth.

A Pan Am Hub Reborn as a Two-Storey Terminal
Robertsfield, as everyone in Liberia calls it, has a history out of proportion to its size today. Pan American Airways began developing the field in 1941 under an arrangement with the US War Department, and the Firestone company did the construction. The runway was built long enough for refuelling bombers, giving Liberia what was for years the longest runway in Africa, at 11,000 feet or about 3,350 metres, and it was later listed as an emergency landing site for the Space Shuttle. In the late 1970s Pan Am used it as its main African hub, with Boeing 747s from New York.
The terminal you arrive in today is much newer. The original building was burned out in the civil war and stood empty for years; the new two-level, 5,000 square metre terminal was built on its salvaged structure with a Chinese Export-Import Bank loan, re-dedicated on 24 July 2019 and fully operational by September that year. It is designed for 320,000 passengers a year and gave the airport its first two jet bridges. Arrivals, baggage claim and the meeting area are on the ground floor, with the departures gallery, shops and the business lounge upstairs.
Who flies in
Recent schedules show Brussels Airlines from Brussels via Freetown, Royal Air Maroc from Casablanca, Ethiopian Airlines from Addis Ababa, Kenya Airways from Nairobi via Accra, and regional services from ASKY, Air Cote d'Ivoire and Air Peace linking Abidjan, Accra, Lome, Banjul and Lagos. Monrovia's other airport, Spriggs Payne, is right in the city but has had no scheduled international flights since 2014, so nearly every visitor lands at Harbel.
The Orange and Lonestar Booths at the Exit
There is nothing for phones airside. The two operator booths sit immediately outside the terminal once you have cleared immigration and customs, so you reach them with your bags. A traveller guide updated in September 2026 reports that both Orange and Lonestar give the SIM card itself away free here if you show your passport, whereas in town it costs around a dollar. You then pay for a data bundle, bought with a scratch card from the same booth.
Getting a line at ROB, in order
1. Keep your passport in hand after immigration; you will need it again at the booth.
2. Decide on the network before you queue. Orange generally reaches further upcountry, Lonestar is often quicker in Monrovia.
3. Have small US notes ready. Bundles are priced in US dollars, and a 10 dollar Orange Monthly Turbo gives 10 GB over 30 days.
4. Ask the agent to activate the bundle and check the balance on *352# before you step away.
5. Open a map or send a WhatsApp message to confirm data works, then head for the car park.
We could not confirm the booths' opening hours. They are staffed around flight arrivals, but a delayed late-night landing, which happens on this route, is exactly when a counter is most likely to be closed or swamped. If you arrive after dark, the booths are a convenience to use if open, not something to depend on.
Dollars, Small Notes and the Terminal WiFi
Liberia runs on two currencies. The US dollar is used for almost everything a visitor buys, from SIM bundles to the taxi fare, and the Liberian dollar circulates alongside it for small purchases. In Monrovia ATMs dispense both. At the airport we could not confirm a working ATM or exchange desk at the time of writing, so arrive with enough US cash in small denominations to cover the bundle and the ride into town; drivers and booth agents often cannot change a 50 or 100 dollar note.
Treat the airport WiFi as a bonus
We could not confirm a public WiFi network name or login at Roberts International, and we found no recent traveller reports of it working reliably. Do not plan to download an eSIM after landing. The better moment is during your connection: Brussels, Casablanca, Addis Ababa, Nairobi and Accra all have dependable terminal WiFi, and an eSIM installed there can be switched on as soon as you taxi in at Harbel.
One local detail is worth knowing for the drive. The plantation land around the airport is Firestone's concession, one of the largest rubber estates in the world, and the road through it is lined with rows of rubber trees for several kilometres. Signal along that stretch is weaker than in Monrovia, so make your important calls before you leave the terminal forecourt.
The Robertsfield Highway, and Paying for the Ride
From Harbel the route runs north on the Robertsfield Highway towards the eastern edge of the capital at ELWA Junction in Paynesville, then west along Tubman Boulevard into Sinkor, Congo Town and on to Mamba Point and the centre. Expect around an hour in light traffic and up to ninety minutes when the Paynesville stretch is congested or the rains are heavy.
| Option | How it works | Time | Roughly |
|---|---|---|---|
| Airport taxi | Unmetered, agreed before you get in | 60 to 90 min | Reported from about $27 up to $40 to $60 to central Monrovia |
| Hotel transfer | Booked ahead, driver meets you with a sign | 60 to 90 min | Reported at $50 to $80 |
| Organisation vehicle | Arranged by your NGO, embassy or employer | 60 to 90 min | Usually no charge to you |
| Shared transport | Shared cars and minibuses from the highway | 90 min or more | Cheap, but not suited to luggage or a first arrival |
Taxi quotes vary widely, which is why the price must be agreed before loading bags. Many hotels and almost all international organisations arrange a pickup, and for a first visit that is the advice most often given. We found no ride-hailing app we could verify operating from the airport, so do not plan your arrival around one.
Why connectivity matters on this transfer
A long drive after dark on an unfamiliar highway is when being reachable matters most. With a working line you can share your live location with a colleague, confirm the driver's name and plate with your hotel, and tell someone when you reach the city. That is the strongest argument for arriving connected at ROB, stronger than anything to do with the price of data.
Booth Bundle or eSIM: The Numbers
Set the options side by side and the money case for the booth is plain.
| Where | What you get | Price |
|---|---|---|
| Orange booth | Free SIM plus Monthly Turbo, 10 GB, 30 days | $10 |
| Orange booth | Free SIM plus Weekly Turbo, 6.5 GB, 7 days | $5 |
| Lonestar booth | Free SIM plus 5.6 GB, 7 days | $10 |
| Lonestar booth | Free SIM plus 30 GB, 14 days | $30 |
| Nomad eSIM | 5 GB, 30 days, Orange | $27 |
| Nomad eSIM | 1 GB, 7 days, Orange | $7 |
| Airalo eSIM | 1 GB, MTN | $6 |
| Holafly eSIM | Unlimited, 7 days | $40.90 |
Unusually for an airport, the booth here is not a rip-off: the card is free and the bundles are the same US dollar prices the operators publish nationally. An eSIM costs more for the same data in every row. What it saves is the queue at the end of a long journey, the dependence on a booth being open, and the risk of leaving the airport with no way to reach anyone.
For a short business visit, Nomad's 7 dollar gigabyte covers the transfer, maps and messaging for a week. For a longer stay, a sensible pattern is to land on a small eSIM, then pick up an Orange or Lonestar card in town, or at the booth if the queue is short. Full prices are in the Liberia eSIM guide, local bundles in the Liberia SIM card guide, and the eSIM Finder will match a plan to your dates.
Landing Connected or Queueing at the Booth
At ROB the choice turns on your arrival time and who is waiting for you, more than on the price of a gigabyte.
Arriving with an eSIM working
Using the airport booth
Most travellers reach Monrovia on a connection, through Brussels, Casablanca, Addis Ababa, Nairobi or a West African hub such as Accra, Abidjan or Lome. Install the eSIM during that layover, while the WiFi is reliable, and switch on the line once the aircraft has parked at Harbel.
Frequently Asked Questions
How far is Roberts International from central Monrovia?
About 56 km, or 35 miles. The airport is at Harbel in Margibi County, next to the Firestone plantation, and the drive along the Robertsfield Highway and through Paynesville usually takes an hour to ninety minutes. Allow more in the rainy season or at evening rush hour, and more again for a flight home.
What does the SIM cost at the airport booths?
A traveller guide updated in September 2026 reports that the Orange and Lonestar booths outside the terminal hand out the SIM free with a passport. You pay only for the bundle, for example 10 dollars for Orange's 10 GB month or 5 dollars for its 6.5 GB week. Bring small US notes.
What should I pay for a taxi from ROB to Sinkor or Mamba Point?
Reported fares range from around 27 dollars to 40 to 60 dollars for central Monrovia, and hotel transfers from 50 to 80 dollars. Taxis are not metered, so agree the price in US dollars before loading bags. For a first visit, a pre-booked hotel or organisation pickup is the more common advice.
Can I count on WiFi in the terminal to set up an eSIM?
No. We could not confirm a public WiFi network at Roberts International, and we found no recent reports of it working reliably. Install the eSIM at home or during your layover in Brussels, Casablanca, Addis Ababa, Nairobi or Accra, then switch it on after landing so it is working before you reach the booths.
Is there an airport closer to the city?
Spriggs Payne Airport is inside Monrovia, in Sinkor, but it has had no scheduled international service since 2014. Nearly all international passengers use Roberts International at Harbel, which is why the long transfer, and having a phone that works on it, is part of every trip to Liberia.
