How to solve the problem of iphone no service

When your iphone says "No Service" you will be put in a tight spot. Because you can't call or receive calls, you can't sent messages, and you can't use internet unless Wi-Fi. It's trouble for modern people. So In this article, I will explain the reason of iphone no service and the solution of iphone no service.

Why does your Iphone Say No Service?

The world hasn't a universal approach to accomplish this problem, so we will step-by-step to do. If the method have no effect, then you need professional to check your iPhone.

1.Check in your Account

You can give your carrier a call to ask whether or not all going well, yet easily-overlooked reason for this problem. If it's not the reason you will take a look at your iPhone’s software.

2.Update your iphone's Software

If you can connect to Wi-Fi, you can update for your iphone, beginning at Setting->General->Software Update. If an update isn’t available, you can beginning at Setting-> General -> About to check for a carrier settings update. Just wait 10 seconds or so, and if nothing pops up, your carrier settings are up to date.

If you can't connect to Wi-Fi, you can connect your iPhone to your computer and use iTunes to check if a software update is available for your iPhone. It can auto update.

3.Take out your SIM card

Your iPhone’s SIM card links your iPhone to the cellular network. It’s how your carrier distinguishes your iPhone from all the others. Sometimes, your iPhone will stop saying No Service simply by removing your SIM card from your iPhone and putting it back in again.

How to repair your iphone no service?

1. Checking “settings”→ “general” → “about phone” after power on，there is IMEI. But there is no IMEI when dialing *#06# at the dialing interface. Repeating power on several times, sometimes there is IMEI. This kind of trouble is called *#06# no IMEI. Usually, this is caused by the troubles of RFFE1 and RFFE2 serial of the baseband. The two serials are used by baseband CPU to control the signal chips. 


2. Dropped iPhones have such phenomenon because RFFE1_DATA is broken at the bottom of U1. After teardown the baseband, using an enameled wire connects the test point at the back.

3. After enameled wire connects the test point at the back, then smearing green oil and assembling the baseband.


4. Assembling the motherboard to the assembly, then power on, “no-service” doesn't appear any more after testing for several days. The trouble is removed. 

Last, When your iphone no service if you can't check it you need a professional repairman to help you, or you can appeal to for vipprogrammer.
