Before You Buy Data in Guinea-Bissau: 6 Checks After the MTN Exit
The timeline in short
| When | What happened |
|---|---|
| March 2024 | MTN agreed to sell its Guinea-Bissau and Guinea-Conakry businesses to Telecel Group, each for a token price of one US dollar |
| Mid 2024 | Guinea-Bissau had about 894,000 MTN customers |
| 2024 | The Guinea-Bissau sale was completed after regulatory approvals |
| After the sale | Telecel Group took over the operation and its liabilities |
MTN described the business as too small to grow on its own. The owner changed, but the work of keeping people connected carried on. For customers, the main question is what changed on the ground.
What we know and what we do not
MTN has exited Guinea-Bissau and Telecel Group is the new owner.
The exact new brand name on shop fronts, the new menu codes, the new prices and the new customer care numbers.
Because of that gap, I will not give you a list of MTN Guinea-Bissau data codes. A guessed code can be wrong or costly. The sections below show you how to get the real ones in a few minutes.
Find your bundles safely
| 1 | Open your SIM menu or the operator’s menu if your phone shows one. |
| 2 | Look for data or internet bundles and read the price, size and validity. |
| 3 | Ask in a shop for the current price list and request it in writing. |
| 4 | Photograph the list and keep it. |
| 5 | Before you buy, check whether renewal is automatic. |
Find customer care you can trust
- Use the number printed on your SIM card pack or inside the operator’s own app.
- Ask a shop for the support number and the hours.
- Do not trust a number from a forwarded message or an unofficial page.
- Keep the date, the time and the agent’s name whenever you complain.
Official services in Guinea-Bissau are often offered in Portuguese. Ask the agent to write down any reference number so you can follow up.
Your SIM, balance and mobile money
Ask the shop whether your old SIM still works with the same number, whether you need to re-register and whether any money in a wallet linked to your line is safe. Ask about changes to the PIN. Do not share your PIN with anyone, including shop workers.
Roaming and travel
If you travel, ask which foreign networks work with your SIM now and how much calls and data cost. Ownership changes can affect roaming agreements. Confirm before you leave, not at the airport.
Common problems after a change of owner
Menus are often rebuilt. Use the on-screen menu or ask a shop.
Compare with your last receipt or message. Report any gap with the date and amount.
Prices change. Compare by cost per GB and check the validity.
Network upgrades can cause short outages. Report persistent faults.
Keep your own records
After any ownership change, your own notes are your best protection. Each time you top up, write the date, the amount and the balance you see afterwards. Each time you buy a bundle, keep the confirmation message and note when it should expire. If a charge looks wrong, you can show the shop a clear record instead of trying to remember. A simple notebook or a photo of each message is enough. This habit takes seconds and has solved many billing disputes.
Protect yourself from scams
- Never send your ID photo, PIN or SIM number in reply to a message.
- Do not click links offering free data or “migration”.
- Buy airtime only from known sellers.
- Check any official announcement against the shop or the regulator.
Questions people ask
No. The business was sold to Telecel Group in 2024.
Only if the operator says so. Ask in a shop before you pay for anything.
Number changes should be announced clearly. Ask the operator in writing.
Start with the operator. If the issue is not solved, the national telecom regulator can receive consumer complaints.
The safe way forward
Check what your own SIM menu and an official shop tell you today, keep your receipts and messages and avoid any code or price list that cannot be traced to the operator. That is the best way to deal with a network that has changed hands.
