SIM-Card Registration Study

5.1 billion people worldwide have mobile phones, accounting for almost 70 percent of the entire global population, according to the GSM Association.

The majority of national governments (around 150) require mandatory SIM-card registration, which means you need your real name and personal details to sign up for phone service. Just how private is mobile phone usage in each country? And how are governments using the data collected?

Here at Comparitech, we looked at a number of factors to determine where in the world SIM-card registrations are the most invasive. This includes if biometrics are required in the registration process, whether the data is stored by providers or shared with government agencies, what is (or is not) required for law enforcement to gain access to this data, for how long the data is stored, and whether any data privacy legislation protects this information.

This map includes all of the countries we know of that have or do not have SIM-card registration laws. Some of these have been omitted from the overall study (with scorings and rankings) due to insufficient information on the laws and processes in place. Therefore, it wouldn’t be fair for us to include them as we cannot accurately score them for things like law enforcement access, penalties, and so on.

Top 15 countries with the worst SIM-card registration policies

  1. Tanzania (19 points) – Tanzania is at the top of our list with a score of 19/21. It manages to scrape back two points due to citizens being allowed a maximum of eight sim cards (one per provider) and law enforcement not having invasive interception tools (although they can access data without a warrant). Subscribers’ information is submitted to the relevant authority once a month and registration includes fingerprints. This data isn’t protected with storage limitations and with no data protection law in place, this leaves subscribers’ data open to various vulnerabilities. Furthermore, those who don’t comply with the law may find themselves being fined 7 million Tanzanian shillings (US$3,000) and/or spending more than two years in prison.
  2. Saudi Arabia (17 points) – Fingerprints are a requirement for anyone registering for a SIM card in Saudi Arabia and all of this data collected has to be validated by the provider before the SIM card is activated. Law enforcement has access to this data and may not need a warrant. No data storage limitations are mentioned and no data protection law is in place. Furthermore, residents are limited to 10 SIM cards.
  3. North Korea, Uganda (15 points) – Both North Korea and Uganda receive 15 points but for slightly differing reasons.
    • North Korea scores poorly due to mobiles and their networks being supplied by the government, thus restricting people’s access to multiple SIMs and their privacy when using their mobiles. For example, if a user accesses something that they shouldn’t, they are sent an alert warning them that the government has noted this action. Users who don’t follow the registration process can receive prison sentences for as long as three years and could also face hefty fines. North Korea fails to protect registration data with no telecommunication storage retention or data protection laws. The government has ensured tourists aren’t able to leave SIM cards with residents by deactivating the SIM card after their visit and charging tourists $250 per SIM card.
    • In contrast, Uganda doesn’t restrict the number of SIM cards used and enforces the requirement of a warrant to access customer data. However, Uganda’s poor score is due to its biometric checks for SIM-card registration, its capture and validate system, its lengthy storage retention laws (5 years after a contract is terminated or canceled), and its use of fines and/or imprisonment for those who fail to comply.
  4. Lebanon, Pakistan, Singapore, Sri Lanka (14 points) –
    • Lebanon’s poor score comes from its limit of three SIM cards per person and its lack of protection for data collected. Lebanon is discussing the possibility of biometric checks.
    • Pakistan’s score results from the use of fingerprints in the SIM-registration process, its capture and validate system, and its limit of five SIM cards per person.
    • Singapore scores poorly due to the use of facial recognition, the limit of three SIM cards per person, and severe penalties for more extreme cases (excessive use of unregistered SIM cards).
    • Finally, while Sri Lanka doesn’t use biometrics, it does fall short when it comes to SIM card limits (five per person), potential access to data without a warrant, and lack of data protection.
  5. Bahrain, Bangladesh, China, Myanmar, Nigeria, Tajikistan, United Arab Emirates (13 points) – Bahrain, Bangladesh, and China have very similar scores across the categories. All of them employ a capture and validate system, use fingerprints or facial scans in the registration process, allow law enforcement access without a warrant, and store data for lengthy periods of time.
    • Myanmar is the only one of this group not to use fingerprints in the data collection process but scores poorly due to its SIM card limit (two per person) and lack of data protection.
    • Both Nigeria and the United Arab Emirates have implemented severe penalties for those who don’t register their SIMs (imprisonment and/or fines).
    • Tajikistan limits users to four SIM cards.
    • Nigeria, the UAE, and Tajikistan score poorly due to their data retention periods either being lengthy or unclear.

Type of ID required by country

The countries that currently have biometric registration laws are Afghanistan, Bahrain, Bangladesh, Benin, China, Nigeria, Oman, Pakistan, Peru, Saudi Arabia, Singapore, Tajikistan, Tanzania, Thailand, Uganda, United Arab Emirates, and Venezuela. Those who are in the planning stages of implementing biometrics are Jordan, Lebanon, and Liberia. In Mozambique, subscribers can provide their fingerprints if they don’t have adequate ID.

In China, anyone registering a new phone number now needs to submit a facial scan. This is also happening in Singapore. Singtel, which has a market share of 50 percent, introduced facial scanning to its ID-verification process. All of this can be done from an app on the user’s phone. Nigeria also requires both fingerprints and a facial image.

In all of the remaining countries (that we conducted our in-depth study on) where biometrics aren’t yet implemented, photo ID is a requirement in order to register. If someone doesn’t have ID, authorities often implement rules stipulating they register through another person or seek a sponsor who will vouch for them.

In many countries, other requirements are stipulated alongside the ID, including a permanent address, date of birth, nationality, and gender (many personally identifying factors that may also be included on the ID). However, certain countries also have other unique stipulations. For example, in Chile and Sudan, your mother’s name is required on the registration form. Kosovo, Liberia, and Mali also want to know your profession, while Cameroon requires you to submit a localization map to confirm your country of residence.

Countries without mandatory SIM-card registration laws

Those without any SIM-card registration requirements are Andorra, the Bahamas, Bosnia and Herzegovina, Cabo Verde, Canada, Colombia, Comoros, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Hong Kong, Iceland, Ireland, Israel, Kiribati, Latvia, Liechtenstein, Lithuania, Maldives, Malta, Marshall Islands, Mexico, Micronesia, Moldova, Namibia, the Netherlands, New Zealand, Nicaragua, Paraguay, the Philippines, Portugal, Romania, Serbia, Slovenia, Solomon Islands, Sweden, Ukraine, United Kingdom, United States, Vanuatu, Vietnam, and Yemen.

There are certain countries where SIM card registration is under discussion, e.g. Cyprus, Malta, Namibia, and Vietnam. Equally, in some countries, bills and even laws have been introduced but retracted. This includes Lithuania, Paraguay, the Philippines, Romania, and Ukraine.

How does SIM-card registration threaten privacy?

Creating a database of citizens and their mobile numbers restricts private communications, increases the potential of them being tracked and monitored, enables governments to build in-depth profiles of their citizens, and risks private data falling into the wrong hands.

A SIM card is more than a phone number. It allows authorities to easily track people’s locations and movements. All of their online activity—websites visited, search queries, purchases, and more—can be traced back to their device. Authorities could selectively throttle, censor, or block internet connections of specific people or groups of people, giving way for harassment and persecution.

Without laws to protect registration data, personal details could be shared with third parties. These could include advertisers, other governments, or tax collection agencies, for example. This puts data at a higher risk of theft and abuse.

In China, SIM-card registration is combined with real-name registration for online accounts and services. When you sign up for a social media account or chat app, for example, you’re required to provide your real name and phone number. In combination with SIM-card registration, the policy prevents anyone from making anonymous accounts online or communicating in secret.

Furthermore, Spain recently conducted a large study of its citizens’ phone tracking data in a bid to improve its public services. Even though this data was “anonymized,” it still demonstrates the intrusive ways governments may choose to use mobile data that’s made available to them. There were also some suggestions that the data was used against privacy laws as people hadn’t given their consent for the data to be used by the government.

Some experts also suggest that having mandatory registrations in place for SIM cards only seeks to fuel their illicit use. It creates the need for a black market as people want to communicate anonymously and it also encourages identity fraud as people try to evade the system.

Identity theft is also a threat to this system. Criminals might have little trouble finding someone else’s photo and other information required to sign up for a new SIM. This could cause a lot of trouble for the impersonated with little consequence to the impersonator.


To conduct this study we have used various sources (listed below) to find out whether or not SIM-card registration is mandatory or not. We then followed this up by taking an in-depth look at each country’s laws to find out how this data was used, stored, accessed, and so on.

Where we were unable to find this information, we have omitted the country from the study.


Registration required = No (0 points), Yes (1 point), Optional (0.5 points)

Capture and Store = 1 point

Capture and Share = 2 points

Capture and Validate = 2 points

Data Privacy Framework = Yes (0 points), No (1 point)

Biometric Check = Fingerprints used for limited groups (i.e. those without ID (2 points), Fingerprints and/or Facial Scans (3 points), In progress (1)

Sim Card Limit = No limit (0 points), over 10 or other restrictions (1 point), 6 to 10 (2 points), 5 or less (3 points)

Law Enforcement Access = With warrant (1 point), without warrant (2 points), severe interception capabilities (3 points)

Penalties = Subscriber deactivation (1 point), subscriber penalties (2 points), subscriber prison sentences and/or penalties (3 points)

Data Storage = length of contract and up to six months after (1 point), up to 1 year (2 points), 2 to 3 years (3 points), 4 to 5 years (4 points), 6 or more years (5 points). If no data storage timescales are given, countries are allocated 5 points if there is no data protection law and a 3 if there is a data protection law in place (as this will put some safeguards in place despite no timescales being given).
