No Service Problem for iPhone 11, 11 Pro, 11 Pro Max
There are many reasons why an iPhone might display “No Service.” However, if you own an iPhone 11 series, it’s highly likely that the issue is caused by a common motherboard problem referred to as “No Service Disease.” This term describes the failure of one of the network chipsets on the motherboard.
Even if the issue is intermittent, it still falls under this well-known problem. For instance, you may experience situations where your phone should connect to a 4G signal, but instead, it switches to “E” when you try to use it.
Is It a Motherboard Problem?
In Malaysia, the term “motherboard” is often used instead of “logic board.” Before suspecting a motherboard issue, it’s crucial to thoroughly check the phone. A common issue here is “Telco Lock,” where an iPhone is blacklisted by the telecom provider, preventing the use of Malaysian SIM cards. You can learn more about this in our YouTube video.
If the device is not blacklisted, the issue is likely hardware-related. Restoring the iOS software won’t fix the “No Service” problem, as it’s usually caused by a faulty motherboard.
Check Which Part of the Motherboard is Damaged
The next step is identifying the specific motherboard issue causing the “No Service” problem.
As mentioned earlier, the issue could originate from the Baseband circuit or one of the Network IC chipsets. Knowing whether it’s a Baseband or Network IC problem is crucial, as the repair costs can vary significantly.
To help you diagnose the problem, we’ve outlined some simple steps below.
How to Check if It's a Network IC Problem or Baseband Problem?
- Open the phone dialer and dial *#06#.
- If the IMEI page appears, it means the Baseband circuit is functioning. If it doesn’t, this could indicate a Baseband circuit failure or something else.
If the IMEI page does show up, it’s likely that your iPhone 11 series is experiencing the “No Service” issue.

No Service: A Network Circuit Problem
“No Service” refers to a network issue involving the IC or circuit responsible for network functions. Technically, an iPhone motherboard contains various network chipsets, each serving different telecom companies. However, in Malaysia, we simplify the explanation, especially for our readers who are primarily end-users.
If you’ve confirmed that the Baseband circuit is functioning, the issue lies within the network circuit. This is the focus of our discussion today—commonly referred to as the “No Service Disease.”
How Much To Repair No Service Disease?
The prices provided here are latest for the year 2024. if your device has been previously repaired by someone else, and their repair attempt was unsuccessful, the cost of fixing it may be higher. It depends on the condition of the motherboard because entrusting it to an inexperienced technician can potentially lead to additional issues, making the problem even more challenging or causing hidden problems to emerge.
Repair Duration?
If you schedule an appointment in advance, we can complete the repair on the same day. Estimate 4-5 working hours.
Otherwise, the device will be ready for collection on the next day.
Why is Repairing This So Expensive?
The cost of repairing an iPhone logic board may seem high, but it reflects the complexity of the work. Logic board repair requires meticulous precision, specialized tools, and extensive training. It’s comparable to a delicate surgery—just as you’d want a highly skilled surgeon for your heart, you’d want an experienced professional for your iPhone.
Our goal is not just to repair the motherboard but to ensure your phone functions perfectly afterward. A half-done repair is of no use if the device still doesn’t work properly.
It’s far safer to trust professionals with the necessary expertise. Allowing inexperienced individuals to “learn on your iPhone” could result in further damage, costing you more time and money in the long run.
To better appreciate the level of precision and detail involved, watch the videos below. You’ll see how even the smallest mistake during the repair process can lead to serious damage to the motherboard.
