Your phone number in Uganda is more than a way to make calls. It holds your mobile money, bank alerts, WhatsApp and many logins. That is why SIM registration rules are strict and why losing a SIM can be stressful. This guide explains how to register a new SIM, replace a lost one and protect your line.
Why SIM registration matters
The Uganda Communications Commission (UCC) requires every SIM card to be registered to an identified person. Registration is checked against the National Identification and Registration Authority (NIRA) database. Unregistered or wrongly registered lines can be switched off.
Documents needed to register a SIM
- Ugandan citizens: National ID card, or your National Identification Number (NIN) for verification.
- Foreign nationals: a valid passport, plus the visa or permit details required by the operator.
- Refugees: refugee identity documents issued by the Office of the Prime Minister.
- Companies: company registration documents, an authorisation letter and the IDs of authorised persons.
Children cannot register lines in their own names. A parent or guardian registers and remains responsible.
How to register a new SIM
- Visit an official MTN or Airtel service centre, shop or authorised agent. Avoid street sellers offering pre registered SIMs.
- Present your ID. The agent captures your details and photo and verifies your NIN with NIRA.
- Receive your SIM and wait for activation, usually within minutes once verification succeeds.
- Check that the line is in your name using your network's self service menu or by asking customer care.
How to replace a lost or damaged SIM (keep the same number)
- Block the line immediately. Call your network's customer care from another phone and ask them to block the SIM and mobile money wallet.
- Go to a service centre in person with your original National ID or passport. SIM replacements are not done for third parties without strict authorisation.
- Answer verification questions. You may be asked for recent numbers called, mobile money activity or your registered details.
- Pay the replacement fee if applicable and receive a new SIM with the same number.
- Restore services. Mobile money, bank alerts and WhatsApp should work again, though some services may require extra verification or a waiting period.
Upgrading to a 4G, 5G or eSIM
Old SIM cards may not support 4G or 5G. Operators can swap you to a new SIM with the same number. Many newer phones also support eSIM, a digital SIM installed by scanning a QR code at a service centre. Bring your ID for any swap.
How to check how many lines are registered in your name
Fraudsters sometimes register lines using other people's details. Use your operator's self service USSD menu, app or customer care to check lines on your NIN. If you see a number you do not recognise, ask the operator to deregister it and report it.
SIM swap fraud: how to protect yourself
SIM swap fraud happens when a criminal convinces or bribes someone to issue a new SIM for your number, then uses it to receive mobile money PINs and bank codes.
- Warning sign: your phone suddenly shows "No service" or "SIM not registered" in an area with good network.
- Act fast: call customer care from another phone and your bank immediately.
- Never share your mobile money PIN, one time passwords or ID photos with callers claiming to be from the network.
- Set a strong PIN and change it regularly. Avoid birthdays.
- Turn on two step verification on WhatsApp and use app based authentication for email where possible.
- Limit the ID photos you send online. Your ID can be misused to register lines.
What happens to unused lines?
Operators typically recycle numbers that have been inactive for a long period. If you have an important number, make at least one chargeable activity such as a call, SMS or data use regularly to keep it active.
Frequently asked questions
Can someone else replace my SIM for me?
Generally no. SIM replacement requires the registered owner in person with original ID, to prevent fraud. Companies follow a formal authorisation process.
Will I lose my mobile money balance?
No. Your mobile money account is linked to your number and identity. Once the replacement SIM is active and verified, your balance remains.
Can I register a SIM with a NIRA registration slip?
Operators verify against NIRA records. Many accept your NIN once it is confirmed in the system. Ask your operator for current requirements.
