No Service Disease Logic Board Problem on iPhone 11, 11 Pro, 11 Pro Max
There are many reasons why an iPhone may show ‘No Service.’ But if you own an iPhone 11 series, it’s highly likely that the issue is caused by a common motherboard problem known as ‘No Service Disease,’ which refers to a failure of one of the network chipsets on the motherboard.
Even the problem is intermittent, it’s still considered one of this famous disease.
Is it a motherboard problem?
In Malaysia, we use the term ‘motherboard’ to refer to what is commonly known as the ‘logic board’ in other places. So, before we suspect that it’s a motherboard problem, we should thoroughly check the phone. In Malaysia, there’s also a common issue known as ‘Telco Lock,’ which occurs when an iPhone is locked by the telecom provider and blacklisted, preventing it from using any Malaysian SIM cards. For more information, you can watch our YouTube video.
Once we’ve confirmed that the device is not blacklisted, we can conclude that it’s a hardware issue. It’s important to note that simply restoring the iOS software won’t resolve the ‘No Service’ problem, as it’s usually caused by a faulty motherboard.
Check which part is damage in the motherboard
The next step is pinpointing the specific motherboard issue responsible for the ‘No Service’ problem.
Like I mentioned before, there could be different reasons for this issue, like a problem with the Baseband circuit or one of the Network IC chipsets.
It’s important to know if it’s a Baseband or Network IC issue because the cost to fix it can be very different.
We’ve put together some steps in below to help you find out which problem.
Baseband problem or Network IC problem?
First, go to the phone dial-up page and dial *#06#. If an IMEI page shows up, it means the Baseband circuit is working. If not, it could be a Baseband circuit failure.
If the IMEI page is present, it’s likely that your iPhone 11 series is affected by the No Service Disease.

No Service Disease is Network Circuit Problem
We can refer to it as a network issue, involving the IC or circuit responsible for network functions. Technically, there are various network chipsets on the iPhone motherboard, and different telecom companies use different ones. However, in Malaysia, we keep it straightforward, especially for our readers who are mostly end-users.
Once you’ve confirmed that the Baseband is functioning, the issue lies within the network circuit, which is the focus of our discussion today – the ‘No Service Disease.’
How much to repair No Service Disease?
The prices provided here are accurate for the year 2023 and will remain unchanged until 2024. However, 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.
If you schedule an appointment in advance, we can complete the repair on the same day. Otherwise, the device will be ready for collection on the next day.
Why so expensive?
The reason why our repair services are relatively expensive is because repairing an iPhone logic board requires delicate work, expensive tools, and extensive training. It’s akin to undergoing surgery and choosing a skilled surgeon to operate on your heart.
Our primary goal is to ensure that any issue with your motherboard is completely resolved. After all, what’s the use of repairing the motherboard if your phone still doesn’t function properly?
It’s wiser to entrust such tasks to professionals who have the necessary experience and expertise. You wouldn’t want your iPhone to be used as a learning opportunity for amateurs who may end up causing more harm than good.
To get a better understanding of the intricate steps and the level of precision involved in the repair process, please watch the videos provided below. Even a minor mistake during the repair can lead to significant damage to the motherboard.
