Z3 not signal bars

Hi,

 

First of all I want to tell I tried to search all the morning this issue in internet but I didnt find it so I create this post.

 

The problem is my z3 D6603 stop giving signals bars, I only see the icon of the Signal but no bars.

 

So what I tried

  1. Restart
  2. Changing to GSM , LTE , ....
  3. Using another SIM
  4. Factory Reset

my phone was working good yesterday and I never had this problem before.

How old is your SIM card?

 

is it a NANO SIM card?

 

Is the data on?

 

Do you have the correct APN settings? Settings > more > internet settings > accept

Hi, thanks for the answer

 

Old , is like 5 days ago I change the company recently. 

The other one I used to test is the same old and is working in the phone of my GF and my SIM is working in her phone too.

the data is on? Yes, the probem is I dont have any bars of signal of data or phone signal the icon is clear.

APN setting I tried before factory resent and didnt work.

Is it a NANO SIM card or did you trimmed/cut the SIM card? 

 

What if you manually enter the APN settings?

Re: Z3 not signal bars

The sim card is not trimmed or cut I get it in the t-mobile store, and it works for all the days.

 

I take some picks  This is what I see, So no bars, the APN is ok, I cant find Service providers. so No Service. 

 

Thanks
