The phone doesn't prompt for "Network unlock code"

Simply i am stuck!

A couple of services for unlocking locked devices rejected me because my device doesn't prompt for unlock code.

When i insert non supported sim card the device reboots and that's it, no prompt for entering unlock code, nor when i inserted another sim.

I tried with force USSD code to show me the unlock menu but that doesn't work either.

Answered! View the answer I have this problem too

Is this a good question?

Can you confirm that the phone reads the sim card properly?

It sounds like the phone is rebooting on sim insert because the sim detection pin (basically a spring mechanism in the sim reader) gets triggered and tells the phone the sim tray / sim card has been inserted.

If it says no sim card detected on the lock screen or in the status bar (notification bar menu) the sim card is not being read due to either the sim reader being damaged or the phone having a no baseband or no IMEI issue.

To ensure the sim card is being detected go into phone settings > more > mobile networks

On that page it should display only the network settings for your service provider (the sim card you inserted) if it's blank then it's not reading the sim properly. Try doing a call as well, it will tell you to insert sim card if it has not detected one.

You can check imei (15-digit number) and baseband (version) under phone settings > about phone > phone status / phone info.

In fact there is a baseband version the IMEI looks okay, but when i go to "SIM Status" everything is "Not available". When i try to call it says there is no mobile network available. And the phone doesn't even detect the inserted card in the notification bar.

First i was thinking that it was a software issue so i flashed a new firmware, but now it begins to clear up when you shed some light. I will open the phone and look at the reader, maybe replacing it will fix the problem. I will update the thread asap.


One of the pins of the old sim card slot was broken i replaced it and now it works, the phone prompts for unlock code!


No problem glad I could help.

You can use code. You can add sim to mobile and then use code 7465625#. Now it ask for unlock code use your code.

I have an att locked phone (g8 active) trying to switch to tmo.

I thought I had unlocked it years ago, but I'm not certain.

When I insert the tmo sim, it doesn't prompt for unlock code. In network status, it has the tmo server, so it can read the sim card.

I inserted another sim with a PUK and it asked for the sim card code, accepted it, but then didn't work nor prompted for the network unlock code.

When I try to dial the 7465625# I get emergency calls only, regardless of which sim card I have inserted.




Does let me enter the unlock code.

Then i get the message that it's unlocked, but sadly it still doesn't work 😤 (emergency calls only)

Same problem too ,I have the unlock codes but my phone(Motorola g stylus 2021)no where to put the code


Same problem Moto g Play 2021. No sim network unlock PIN screen after insterting multiple sims. Reads sim.


Even though my Moto G was"unlocked" by Spectrum, the phone still couldn't be used elsewhere for it was "made" for spectrum. Called the FCC! These Internet and cell phone companies are having feuds with each other and trying to make it so only their services for everything can be used. Also found out some cell phones won't work on Spectrums Internet/wi fi!


My Moto too :/ Motorola Edge Plus 5G UW (2022). Just in case this helps anyone- similar to what Debra said above, I read that this phone is a Verizon-specific model. However, in my case, I have 2 identical phones and one of them works fine on AT&T (it wasn't locked when I switched); so I know that's not my problem. Hoping for an unlock!!!
