Glo International Roaming Plans and Codes
Travelling with a Glo line sounds simple: land, switch on the phone and stay in touch. In practice the difference between a smooth trip and a shocking bill comes down to preparation. Roaming means using another country’s network through an agreement with your own, and the price, the rules and the settings all matter.
This guide explains how Glo roaming works for prepaid and postpaid lines, how roaming data bundles are bought, which networks to connect to, and how to avoid the charges that catch travellers out. It is written for people who want a clear picture before they leave.
Roaming offers, countries and prices change, so treat every figure as something to confirm on Glo’s website or app before you travel.
What Roaming Actually Is
When you leave Nigeria, your Glo signal does not follow you. Your phone connects to a local network abroad that has a roaming agreement with Glo. That partner network carries your calls and data and bills Glo, which then bills you. This is why roaming costs more than home use and why connecting to the wrong network can be expensive.
Prepaid and Postpaid Roaming
Glo has stated that prepaid lines are enabled for roaming automatically, while postpaid customers need to activate roaming before choosing a bundle. Even so, a line that is enabled does not mean cheap. Without a bundle, usage is charged at pay-as-you-go roaming rates, which are usually high.
| Line type | Roaming status | Action before travel |
|---|---|---|
| Prepaid | Generally enabled by default | Check airtime, buy a roaming bundle |
| Postpaid | Needs activation | Ask Glo to activate roaming first |
Roaming Data Bundles in Brief
Glo introduced roaming data bundles for travellers in a growing list of countries. They come in different sizes and validity periods, from small packs valid for a few days to larger packs valid for around two months, with prices that rise with the size. According to the announcement, they are bought through the *312# menu by choosing the roaming option. Confirm the current menu path and prices before travelling.
Which Networks to Connect To
Bundles work only on approved partner networks. Glo advises connecting to the networks listed on its website, because choosing another network can trigger pay-as-you-go charges even when you have a bundle. Before leaving, note the approved network names for your destination.
Check Whether Your Destination Is Covered
The bundles launched in about 40 countries on 46 partner networks, covering popular places such as the United States, the United Kingdom, France, Italy, the United Arab Emirates, Kenya, Ireland, Brazil, India and South Africa. Your destination may or may not be included now, so check the current list.
Prepare Your Phone Before You Leave
- Check that the phone is unlocked and supports the network bands used at your destination.
- Update the operating system and key apps while on home Wi-Fi.
- Download maps, tickets and entertainment before you go.
- Turn off automatic app updates and cloud backup over mobile data.
- Note the Glo customer care options that work from abroad.
Airtime and Balance Before You Fly
Keep enough airtime for bundle purchase and emergencies. If a bundle can be bought only with airtime, a low balance can leave you without data on arrival. Check your balance and the bundle price the day before you travel.
Buying a Bundle Before You Go or on Arrival
Glo has said customers can activate a roaming plan before departure or upon arrival. Buying before you leave lets you fix problems at home with customer care and a normal connection. Buying on arrival may be easier if your trip dates are uncertain, but you need a working connection to do it.
Step-by-Step Travel Routine
| 1 | Check that your destination and your phone are supported. |
| 2 | Check your airtime and the bundle price. |
| 3 | Buy the roaming data bundle through the menu or app. |
| 4 | On arrival, switch on data roaming in the phone settings. |
| 5 | Select an approved partner network manually if the phone picked another one. |
| 6 | Check the confirmation SMS and test a web page. |
Phone Settings That Matter
Data roaming must be switched on for mobile data to work abroad, and network selection may need to be manual. Turn off roaming again when you are back in Nigeria. If you do not want any data, keep mobile data off and use Wi-Fi.
Voice and SMS While Roaming
Bundles mostly cover data. Calls and texts while roaming are charged at roaming rates. You may also pay to receive calls abroad. To keep costs down, use messaging apps on data or Wi-Fi for calls and texts, and keep voice calls for urgent matters.
Roaming and Background Data
The biggest cause of a surprise bill is background data. Apps refresh, photos back up and videos auto-play without you doing anything. Switch off background refresh and automatic uploads, and check which apps are allowed to use mobile data.
Check Your Bundle Usage
Check your balance regularly while you are away so you do not run out unexpectedly. If your data is almost used up, switch to Wi-Fi or buy another bundle before you go back to pay-as-you-go rates.
Avoiding Bill Shock
Connecting outside the approved list can switch you to pay-as-you-go rates.
Validity ends even if data is left. Note the end date.
Updates and uploads can burn your bundle in minutes.
Watching video on roaming data is the fastest way to finish a bundle.
Wi-Fi and Local SIM Alternatives
Hotels, cafes and airports often have Wi-Fi, which costs nothing from your bundle. For long stays, a local SIM or eSIM can be cheaper than roaming, but it changes your number for that SIM. Many travellers keep their Glo SIM for receiving verification messages while using a local data plan.
Security Tips Abroad
- Avoid banking on public Wi-Fi unless you use a trusted secure connection.
- Do not share your SIM PIN or OTP.
- Beware of fake network pop-ups asking for payment.
- Keep your phone locked with a strong passcode.
If Roaming Does Not Work
| 1 | Check that data roaming is on and the plane mode is off. |
| 2 | Select the approved partner network manually. |
| 3 | Restart the phone. |
| 4 | Confirm that the bundle was activated and has not expired. |
| 5 | Contact Glo customer care with the exact error and your location. |
After You Return
Switch off data roaming, check your balance and look at the last few deductions. If anything looks wrong, ask customer care to explain and keep your travel dates and screenshots. Unused roaming data usually does not carry over, so plan the size of your next bundle carefully.
Estimating Your Roaming Data Need
Most travellers overbuy or underbuy because they guess. Instead, check how much mobile data you use at home in an ordinary week, then adjust. Maps, messaging and email use little. Video calls, music streaming and photo uploads use a lot. If your home usage is mostly Wi-Fi, your roaming need may be small, and a modest pack could cover a short trip.
A Day-by-Day Data Plan
- Day of arrival: check the confirmation, test a web page, save offline maps while on hotel Wi-Fi.
- Normal days: use messaging apps, load maps on demand and keep video off mobile data.
- Heavy days: plan big downloads for Wi-Fi in the evening.
- Last day: check what is left and switch off roaming before you board.
Business Travellers
If you travel for work, your priorities are reliability and proof of cost. Buy the bundle before you leave, keep the confirmation message and screenshot your balance at the start and end of the trip. Keep a second option available, such as a hotspot from a colleague’s line or hotel Wi-Fi, for important meetings where a lost connection costs more than the bundle.
Long Stays and Students
For stays of several weeks or months, a roaming bundle can become expensive compared with a local SIM or eSIM. Many long-stay travellers keep their Glo SIM for receiving verification messages and use a local data plan for daily use. Think about which messages must reach your Nigerian number and plan accordingly.
Families Travelling Together
Each person needs their own plan, and sharing one line through a hotspot drains data quickly. If several people travel together, compare buying separate small bundles against one large bundle shared through a hotspot. Test the hotspot early, and agree a rule that videos wait for Wi-Fi.
Receiving Verification Codes Abroad
Many bank, email and social apps send codes by SMS to your Nigerian number. If you roam, incoming SMS usually still arrives, though delivery can be slower. If you switch to a local SIM, you may lose access to those codes. Before you leave, check which accounts rely on your Glo number and set up an alternative method where you can.
Mobile Banking While Roaming
Banking apps work on roaming data, but use a trusted connection and avoid public Wi-Fi for sensitive actions. Tell your bank about your trip if it asks, and keep card alerts on. Never share a PIN or OTP, even with someone claiming to be from the bank or from Glo.
Emergency Contacts and Safety
Save the local emergency number for your destination, your country’s embassy contact and the Glo customer care options that work from abroad. Keep a screenshot of these in your photos so you can reach them offline. Share your itinerary with a trusted person at home.
A Pre-Trip Checklist
- Confirm that your destination and its partner networks are covered.
- Check your line type and activation status.
- Keep airtime for the bundle and extras.
- Buy the roaming bundle and save the confirmation.
- Download maps, tickets and entertainment.
- Turn off background refresh and automatic updates.
- Save approved network names and emergency numbers.
Reading Your Confirmation Message
The SMS you receive after buying a bundle is your proof. Read it. It should show the pack, the validity and sometimes the network guidance. Screenshot it and store it in your photos. If a dispute arises later, that message is the first piece of evidence customer care will ask for.
Navigation is one of the best uses of a small roaming bundle, because a route uses far less data than video. Download the map of your destination on Wi-Fi before the trip and use offline navigation where your app supports it. Then live traffic and search use only a little mobile data.
Tablets, Laptops and Other Devices
Tablets and laptops left on mobile data can consume a bundle through updates and background sync. Keep them on Wi-Fi, switch off automatic updates and never connect them through a hotspot without watching usage. If a device has its own cellular plan, check that its roaming setting is switched off.
Emergency Airtime and Backup Options
Keep a small airtime reserve for emergency calls and bundle top-ups, and keep one backup route to the internet, such as hotel Wi-Fi or a friend’s hotspot. Travel is unpredictable, and a lost bag or missed connection is easier to handle when you can still reach people and look things up.
Returning Home Without Surprises
Before you board for home, switch off mobile data roaming and check your bundle. When you land in Nigeria, confirm that your phone has reconnected to Glo and that data roaming is off. Review your balance and recent deductions that evening while the trip is still fresh in your mind.
Keeping Friends and Family Informed
Tell the people who usually call you that your Glo number will be on roaming and that calls may be missed or answered at odd hours. Share your messaging app contact and your hotel details. Fewer surprise calls mean fewer minutes billed at roaming rates, and everyone knows the best way to reach you while you are away.
A short message before you leave, with your travel dates and the best way to contact you, saves a lot of wasted calls on both sides.
