Overcome phone restricted notifications on the phone
Every mobile phone must have its own rules for the settings on the SIM card, be it in airplane mode, for dialing or something else. The SIM card can’t live forever as it could get damaged over time, but that can still be fixed by going to the operator’s branch in town. There are many people who have problems with the SIM card they are using and the incident can only be caused by 2 reasons, namely the SIM card or mobile phone used, sometimes 2 reasons that the patent cannot solve, because there is 1 thing that is a problem that is actually ourselves.
Why us? Because if the two reasons are not resolved, then the fault lies with the user of the phone and the SIM card, which may be incorrectly installed or not properly matched to each other. But when it comes to CDMA, a lot of people don’t use it now and just … only a few providers offer CDMA SIM cardsso the problem of competition between CDMA cards is less than that of GSM. ️
Here I am not going to explain human actions / issues with SIM cards while I am going to share how to use cell phones displaying the word Your phone is restricted or your phone is restricted. Of course this will be a different question, the problem is with the cell phone or the SIM card, and here I will answer, the problem is with both and if there are 3 then all are to blame. 
Well here is the procedure, see below.
First of all, open the phone that is having problems.
Next, please just click on OK, you will be asked for a type of pin, please fill it out with 12345 or 000000. If successful, the message will not be displayed again.
If this is not possible, please contact customer service and ask for the phone restriction code as it is from the SIM card. If you can, just write down the code you get.
If it still doesn’t work, it means there is a problem with the phone and the SIM card placement. Please turn off the phone and check the SIM card placement, try tape with thin paper to test and turn on. If it succeeds, try removing the thin paper and turning it back on.
I used the above method when my phone had this problem and it was the first time I got it and so far this notification is not showing up, maybe the problem is with the phone or SIM card or the user inserted the SIM card incorrectly. This sometimes happens when most cell phones suddenly restart too often. And in my opinion the most powerful way is to call customer service because it’s faster and easier. If you have anything to ask, please comment.
Hopefully useful and good luck
