Not register on network is a common problem found throughout the Samsung Galaxy series. I have written a solution to fix the not registered on network problem, it helped most people but some were still having the problem. However, I have forced my phone to go into that state again “Not Register on network“.I have done some experiments and tried some other tricks to fix the not registered on network problem just for the sake of my visitors that needed another solution.
When I was testing out things, I got another error, and I hope most people are having this as well.
When you go to“Settings > More > Mobile networks, it says “Insert SIM card to access network services? or something similar to that.
If this is the case, updating your Samsung Galaxy will not fix this problem. I had come across a way that works. I am glad to share with you what I’ve done to fix not register on the network -Insert SIM card to access network services.
My Android was saying this just after I replaced the sim card. I went to the mobile setting to select my preferred mobile network but it was saying cannot access sim card, please insert sim.

How to solve not registered on network, Insert sim card error
Method 1
- Go to Settings
- Navigate to Wireless and network
- Tap Mobile Networks
- Press the home button for 2 seconds, while holding the home button, press the power button together for 15 seconds
- Your Galaxy Phone will Blink several times and in some cases, you will see a black screen with line 400, no worries.
- Your phone will reboot by its self, if, for some reason, it doesn’t reboot, hold the buttons with each other again
Method 2
If you had cut your Sim card to adjust to a micro Sim then there are chances that you have cut the Sim card incorrectly. I Have seen many cases where users are seeing No Sim card on their Galaxy Phone, mainly because the Sim card does not cut correctly.
What I would suggest is to get a micro Sim card instead of an altered Sim and try it within your Galaxy Phone or android phone. If it works, then the Sim card is definitely the problem
