Moreover, this article answers common questions people frequently ask about the 0310 sim code, all in simple and easy-to-understand language.
0310 Which Network Code Belongs to Which Company?

To begin with, 0310 is a Zong network code in Pakistan. Zong, officially known as China Mobile Pakistan (CMPak), uses several prefixes, and 0310 is one of them.
In other words, if a mobile number starts with 0310, it was originally issued by Zong. This applies across Pakistan, regardless of the city or province.
Key takeaway:
- 0310 which network code? → Zong
- 0310 which network code in Pakistan? → Zong
- 0310 sim code → Zong SIM
Why Do Mobile Network Codes Like 0310 Exist in Pakistan?
You might ask, why does Pakistan use network codes like 0310 in the first place? The answer is simple yet important.
Pakistan’s telecom system assigns unique prefixes to each mobile operator so that numbers remain organized and easily identifiable. As a result, regulators, operators, and users can quickly determine the original network of any mobile number.
Additionally, these codes help:
- Manage call routing efficiently
- Apply on-net and off-net call rates
- Identify the service provider behind a number
- Support billing and regulatory systems
Therefore, the 0310 sim code is not random; it is part of a structured national numbering plan.
How Can You Instantly Identify 0310 Which Network Code?
Identifying 0310 which network code is actually very straightforward. You only need to look at the first four digits of the mobile number.
For example:
- 0310-1234567 → Zong
- 0310-9876543 → Zong
However, due to Mobile Number Portability (MNP), there is one important detail to remember. Even though 0310 is a Zong code, a user may have ported their number to another network like Jazz, Ufone, or Telenor.
That said, the original network code remains 0310, even if the user switches operators.
What Is Zong and Why Is It Popular in Pakistan?
To better understand the value of the 0310 which network code, it helps to know more about Zong itself.
Zong is one of Pakistan’s leading telecom operators and is known for:
- Strong 4G LTE coverage
- Affordable internet packages
- Competitive call and SMS bundles
- Continuous network expansion
Moreover, Zong was the first operator to launch 4G services in Pakistan, which significantly boosted its popularity among internet users.
Because of these strengths, many customers prefer Zong, and prefixes like 0310 sim code are commonly seen across the country.
Is 0310 Only Used in Specific Cities or Nationwide?
Another common question is whether 0310 which network code in Pakistan applies to certain regions only.
The answer is clear: 0310 is used nationwide.
Zong issues 0310 SIMs in:
- Karachi
- Lahore
- Islamabad
- Rawalpindi
- Faisalabad
- Multan
- Peshawar
- Quetta
- And all other cities and towns
Therefore, you cannot identify a caller’s city based on 0310 alone. It only tells you the original network, not the location.
Can a 0310 Number Be Ported to Another Network?
Yes, absolutely. Thanks to Mobile Number Portability, users can switch networks without changing their mobile number.
This means:
- A number starting with 0310 may no longer be on Zong
- The prefix 0310 sim code still shows Zong as the original issuer
- Actual current network can only be confirmed via MNP check
As a result, while 0310 which network code tells you the original network, it does not guarantee the current operator.
How Can You Check the Current Network of a 0310 Number?
If you want to be 100% sure about the current network of a 0310 number, you have a few reliable options.
Use MNP SMS Service
Simply send the mobile number to 667 (without dashes). You will receive a reply showing the current network.
Use Official Network Apps
Most telecom operators provide apps that display network information.
Use PTA or Trusted Online Tools
Some trusted platforms in Pakistan offer updated network lookup services.
This step is especially useful if you want to benefit from on-net call packages.
