Understanding these prefixes is essential for selecting the right promos, avoiding extra charges, and managing your mobile usage efficiently.
This comprehensive guide will walk you through everything you need to know about the 0991 mobile prefix which network it belongs to, how mobile number portability affects it, the best promos for 0991 users, and important registration details. Whether you own a 0991 number or frequently communicate with one, this article will help you make smarter choices.
What Network Uses 0991?

The 0991 prefix is officially assigned to Globe Telecom, one of the Philippines’ largest and most popular telecommunications providers. Globe offers a wide variety of prepaid and postpaid services with extensive nationwide coverage.
Originally, 0991 numbers were strictly Globe numbers, typically used in prepaid SIM cards marketed under the TM (Touch Mobile) brand or Globe’s main brand itself. TM focuses on affordable prepaid services targeted at budget-conscious consumers, while Globe also caters to premium postpaid users.
Since Globe owns and operates the 0991 prefix, any number beginning with 0991 was initially issued by Globe or TM.
Why Knowing What is 0991 Network Matters
Mobile number prefixes like 0991 play an important role in your mobile experience. Here’s why knowing the network behind 0991 is essential:
- Promo Compatibility
Most promos offered by Globe and TM only work within their own network. If you know 0991 belongs to Globe, you can use Globe or TM promos to maximize your benefits.
- Cost Management
Calls and texts sent to numbers on the same network are usually cheaper or included in promos. If you call a 0991 number and know it’s Globe, you can avoid paying inter-network rates.
- Better Communication Planning
Businesses and individuals can plan better by knowing the network of contacts, saving money and optimizing communication.
- SIM Registration and Troubleshooting
Certain network-specific procedures such as SIM registration or customer support depend on knowing the network affiliation.
Globe vs TM: What is the Difference?
While both Globe and TM use the 0991 prefix, their target markets and services differ:
- Globe Telecom offers a full range of prepaid and postpaid plans with higher-end promos, faster internet speeds, and premium services.
- TM (Touch Mobile) is Globe’s prepaid brand focusing on budget-conscious users who want affordable call, text, and data services.
Both operate on the same network infrastructure, but TM is marketed as the more affordable option, while Globe targets a broader audience including corporate clients.
Can a 0991 Number Belong to Another Network?
Thanks to the Mobile Number Portability (MNP) law in the Philippines, mobile users can now switch providers without changing their numbers. This means a number with the 0991 prefix may have been ported to another network like Smart or DITO.
However, the prefix 0991 stays the same despite switching. This can make identifying the true network based on the prefix alone difficult.
For example, a 0991 number could have been originally Globe but later transferred to Smart. This means promo compatibility and call rates might differ from what you expect.
How to Check the Current Network of a 0991 Number
To avoid unexpected charges or promo issues, verify the actual network of a 0991 number using these methods:
- Ask the number owner directly about their current network.
- Use mobile apps or online tools designed to check network portability status.
- Contact your service provider’s customer care or use their official number checking tools.
Knowing the true network lets you apply the correct promos and save money.

History and Background of Globe Telecom and TM
Globe Telecom started operations in the early 1990s and quickly became a market leader due to its focus on network quality and customer service. To cater to different market segments, Globe launched TM (Touch Mobile), targeting prepaid users who want affordable, no-frills mobile plans.
TM became popular for its budget-friendly promos, especially in rural and provincial areas. Today, both Globe and TM share the same infrastructure but serve different user bases with tailored services.
Understanding Mobile Number Portability in the Philippines
The Mobile Number Portability Act was implemented in 2019, allowing Filipinos to keep their mobile numbers while switching network providers. This consumer-friendly policy encourages competition among telcos and empowers users.
For 0991 numbers, portability means:
- You can transfer your 0991 number from Globe or TM to Smart or DITO.
- The 0991 prefix remains unchanged, potentially misleading callers about the network.
- Promo compatibility and call/text rates depend on the current network, not just the prefix.
Because of MNP, it is important to confirm network status before purchasing promos or making calls.

- Always confirm the network before sending promos or making calls to avoid extra charges.
- Register your SIM promptly to ensure uninterrupted service.
- Choose promo bundles that fit your usage pattern to save money.
