Glo SIM Swap Process and Required Documents
A SIM swap sounds technical, but the idea is simple: your phone number moves from one SIM card to another. People do it when a card is lost, damaged, too old, the wrong size, or when they want to move to an eSIM. On Glo it is a routine service, and it is also one of the most sensitive things that can happen to a number, because whoever controls the SIM receives your calls, texts and codes.
That is why the process asks for identity checks and why you should treat it carefully. A swap done properly keeps your number and gets you back online quickly. A swap done carelessly, or by the wrong person, can expose your bank and social accounts.
This guide explains the process, the documents, the usual problems and the safety steps, so you know what to expect before you go.
What a SIM swap means
A swap links your existing number to a new SIM and switches off the old one. The number, and in most cases your registration, stays the same. What changes is the physical card, or the eSIM profile, that carries the number. After the swap, only the new SIM can make and receive calls and messages.
Common reasons people swap
- The SIM is lost or stolen.
- The card is damaged or not recognised.
- The phone needs a different size of SIM.
- You are moving to a phone that supports eSIM.
- The SIM is very old and keeps failing.
- You suspect your SIM was cloned or misused.
Documents and details you should carry
| Item | Why it matters |
|---|---|
| Your NIN | The identity record your line must match |
| Valid ID | Extra proof, if the staff ask for it |
| Your Glo number | So the record can be found quickly |
| The old SIM, if you still have it | Helps staff process the swap |
| Recent activity details | For example a recent recharge, as proof of ownership |
| Your own presence | The owner is usually required in person |
Requirements can change, so call 121 or ask at a centre if you are unsure. Bring more proof than you think you need.
Step by step: how the swap works
| 1 | Go to an official Glo centre or an authorised outlet. |
| 2 | Tell the agent you want a SIM swap and give your number. |
| 3 | Present your NIN and any ID they ask for. |
| 4 | Let them verify your details against the record, including biometrics if required. |
| 5 | Collect the new SIM and any receipt. |
| 6 | Insert the SIM, restart the phone and wait for activation. |
| 7 | Test calls, SMS and data, and check your NIN link status. |
Is there a fee?
Some swaps may carry a fee, and some may not, depending on the reason and the current rules. Ask before you agree, and get a receipt if you pay. If anyone asks for extra money to hurry the swap, treat it as a warning sign.
How long does it take?
| Stage | Typical expectation |
|---|---|
| At the centre | Often minutes, longer when queues are long |
| Activation of the new SIM | Often within minutes to a few hours |
| Old SIM switched off | At or soon after activation |
| Problems after the swap | Report at once if nothing works within a few hours |
What happens to your airtime and data
Your number stays, so your balance usually follows it, but you should confirm. After the swap, check your airtime and data balances and your active plans. Compare them with what you had before. If something is missing, report it quickly with your ticket number and any screenshots you saved before the swap.
What to do right after the swap
- Test a call to another number and an incoming call.
- Send an SMS and receive one.
- Check mobile data with a small test.
- Check your NIN link status.
- Reinstall or re-verify apps that use your number, such as messaging and banking apps.
- Keep your receipt for a few weeks.
Swapping to an eSIM
Some phones support eSIM, which replaces the physical card with a profile on the phone. Availability for Glo can change, so ask at a centre whether your phone and your line qualify. If it is available, the identity checks are similar. Do not scan unknown QR codes from strangers, since an eSIM profile gives access to your number.
Why SIM swaps are a target for fraud
Criminals who take over your number can receive your one-time codes and try to reset passwords. That is why a swap needs proof of ownership. Be careful with calls or messages asking for your NIN, OTP or personal details, especially from people claiming to be from your network or bank. Never share an OTP with anyone.
- Your phone suddenly loses service and shows no network for no reason.
- You stop receiving calls and messages you expect.
- You get alerts about a SIM change you did not request.
- Your accounts show login attempts or password reset messages.
- Contacts say they got strange messages from your number.
If you suspect fraud
| 1 | Use another phone to call 121 and report a suspected unauthorised SIM change. |
| 2 | Ask them to block the line and note your ticket number. |
| 3 | Call your bank and ask them to freeze or block access linked to the number. |
| 4 | Change passwords on email and social accounts using a safe device. |
| 5 | Visit a centre with your NIN to recover the number. |
| 6 | Report the matter further if money was lost, and keep all proof. |
Swapping for someone else
Because identity matters, centres usually expect the owner to be present. Some cases, such as a person who is unwell or abroad, may be handled differently, but you must ask the centre what they accept. Never send your NIN or ID to someone you do not know to do it on your behalf.
Swap or replacement: is there a difference?
The two words are often used for the same service. In practice, a swap is the general term for moving your number to a new SIM, while a replacement usually points to the case where the old SIM is lost or damaged. The documents and the identity checks are much the same, so you do not need to worry about the label. State the reason clearly and the staff will handle it.
Common problems after a swap
Restart the phone, wait, and check that the SIM is activated. If it stays dead, return with your receipt.
Check your plans and balances, then your internet settings and APN.
Relink using the linking guide, or ask the centre to confirm your link.
Follow each app’s steps, and do not share codes with anyone.
How to complain if the swap goes wrong
Call 121 and say clearly what happened: a swap you requested or did not request, the time, the outlet, and the current state of your line. Ask for a ticket number. If the matter is not resolved in the period set for operators, you can escalate to the NCC toll-free line 622 with your ticket number, or use the complaint form on the NCC consumer portal.
Hello. My Glo number is [number]. On [date] a SIM swap was done at [place] and since then [problem]. Please investigate, restore my service, and give me a ticket number.
How to make the next swap smooth
- Keep your NIN slip safe and easy to find.
- Make sure your registration names match your NIN record.
- Save your number and a note of your plans before you go.
- Go early in the day to avoid queues.
- Use official outlets only.
Questions people ask
Yes in most cases. That is the point of a swap.
No. After the swap the old card is switched off.
Usually not, since the line has to match your identity record.
You can set it up again on the new SIM, but follow the app’s steps carefully.
Call 121 and ask what options exist for your area.
Prepare before you leave home
A little preparation turns a long visit into a short one. Find your NIN slip or number and confirm that it has eleven digits. Check that the name on your registration matches your NIN record. Take a screenshot of your airtime and data balances and your active plans, because this is your proof if a balance goes missing afterwards. Note any plan that renews automatically, and make a list of the apps that use your number for codes.
If you have a bank app on the number, make sure you remember your login details without needing an SMS code, since the code will not arrive until the new SIM is active.
What verification may ask you
Staff may ask for details only the owner would know, such as your full name, your date of birth, the last recharge you made, or a number you called recently. This is not rudeness. It is protection for you. Answer calmly and honestly, and do not guess wildly, because wrong answers can slow the process. If you cannot remember a detail, tell them and offer another proof, such as your NIN and ID.
Protect your accounts before and after the swap
- Before: note which accounts send codes to this number and make sure you can log in without them.
- Before: ask your bank how it handles a SIM change on your profile.
- After: check your bank and email for any login alerts you did not cause.
- After: reset passwords on any account that looked unusual.
- After: turn on an extra login step that does not rely only on SMS, where the service allows it.
The hours around a swap are the most exposed time for your accounts, so slow down and check things carefully during that window.
Phone settings after the swap
A new SIM sometimes needs a small nudge on the phone. Restart it, check that the new SIM is selected for calls, messages and mobile data, and look at your network mode. If your internet does not work even though you have a balance, read the APN guide on this site, because settings can reset when a SIM changes. On a dual SIM phone, make sure the Glo card is placed in the slot you intend to use for data.
Why a swap can take longer than expected
| Cause | What to do |
|---|---|
| Long queue at the centre | Go early in the day or on a quieter day |
| System slowness | Wait a few minutes, then ask staff to retry |
| Details do not match the NIN record | Fix the details before you retry |
| Activation delay after you leave | Restart the phone and wait a few hours |
| Network congestion in your area | Test again later or from another place |
Keep a record of the whole process
Keep your receipt, the time and place of the swap, the name of the outlet, and any message you received. Save screenshots of your balances before and after. If a problem appears later, this record lets care trace the exact event instead of asking you to explain from memory. It also helps if you ever need to escalate, because the regulator will ask for the operator’s ticket details and your timeline.
When the old SIM is still in your hand
If you still have the old card and it simply stopped working, keep it and take it with you. Staff can sometimes read it or at least confirm which card it was, and that speeds up the check on your record. Do not throw it away until the new SIM is working. Once the swap is complete and you have tested everything, you can destroy the old card safely by cutting through the chip, so nobody can reuse it.
If the old SIM was stolen, do not keep waiting for it to turn up. Report it, block it, and let the swap give you a fresh, secure start.
Tips for travellers and people in remote areas
If you live far from a centre or are travelling, plan the swap before you leave, not after your SIM fails. Carry your NIN details, and keep a second way for people to reach you. If you are already stuck, call 121 from a borrowed phone and ask what options exist near your location. Avoid unofficial agents in unfamiliar places, since a fake swap can cost you money and expose your number to misuse. A short delay is better than a risky shortcut.
A quick day-of checklist
- Carry your NIN and ID.
- Take screenshots of your balances.
- Go to an official outlet only.
- Check the details when staff type them in.
- Get a receipt and note the time.
- Test calls, SMS and data before you leave.
- Check your NIN status and your accounts that evening.
Final word
A SIM swap is simple when you are prepared and safe when you stay alert. Bring your NIN and ID, use an official outlet, test everything before you leave, and watch for signs of fraud. Keep your receipt and ticket numbers, and act quickly if anything looks wrong.
