Updated 8 November 2026. This page was first written in June 2021. The short answer below reflects what MPT’s own website says as of November 2026; the original 2021 article is kept further down as a record.
Quick answer: how to check and fix your MPT SIM registration
- Check what is registered: dial *601# from the MPT SIM. MPT says this shows the registration details held for that SIM.
- Re-register (correct your details): in the MPT4U app (update to the latest version first, MPT says), on MPT’s self-care site care.mpt.com.mm, or at an MPT Own Shop / MPT Branded Shop — bring your NRC if you go in person.
- What you need: your full name, clear front and back photos of your original NRC (National Registration Card), and your NRC number. MPT’s FAQ says foreigners use a passport instead of an NRC.
- Limit: MPT says one NRC can register a maximum of two MPT SIMs, as directed by the Posts and Telecommunications Department (PTD). If the app says “already reached two cards”, MPT tells you to go to a shop.
- Write it in Burmese: MPT says Myanmar citizens must enter their details in Burmese, exactly as on the NRC (region/state code, township code, NRC type and the 6-digit number). A registration made in English is one of the reasons MPT lists for receiving a re-registration SMS. Foreigners can enter details in English, as on their passport.
- Help: call MPT’s call centre on 106.
Why it matters: MPT’s re-registration page says customers who get an SMS titled “MPTSimAlert” have 30 days to correct their details, and that outgoing calls and data can be restricted if they don’t. Its FAQ adds that the SIM itself may be terminated and that bank OTP codes sent to the number may stop. In December 2022 Myanmar’s operators said SIM details would be checked against the Ministry of Immigration and Population’s database and SIMs with incomplete or incorrect information would be deactivated. The nationwide deadline at the time was 31 January 2023, which has now passed. MPT’s site does not publish a newer deadline; its FAQ says the exact suspension schedule is not fixed, so if you receive the SMS, act on it rather than wait.
What we could not confirm: whether the old link in the 2021 article (my.mpt.com.mm) still works — it did not respond when we checked — and whether MPT has changed any requirement since its pages were last updated (the re-registration page was last modified in January 2025). Check with *601# or 106 before you act.
