[Q] No SIM Card

Hello, I rooted my Ace and flashed a ROM called WindowsPhone8.0 ROM. It worked great but I had to download the Tweaker app to get the apn and mms settings to work. I rebooted my my devoce and now it does not recognize sims from any carrier.. Would like advice please.
i cant help but have you tried searching on google?

I'm kinda wondering what would happen if you went back to stock ROM ?

[SOLVED] Restricted access changed

The other thread was closed due to use of Spanish I think...
I'm now suffering with this issue.. My city always had a good signal but from last days it started...
Happens every 5min ... Any tip?

Solved. Rooted (JB, finally!), installed Batakang ROM and *#*#4636#*#* (doesn't work at stock JB).. switched to WCDMA only..
Didn't have any disconnection again!
Re: Restricted access changed
Do you upgrade to JB?
Sent from my MB526 using xda premium
Yep but it worked great a few weeks!
is a problem with the quality of the phone network, to me was the same but only in places where the signal was not good, it is a problem of the radio that comes with JB
if we get root.. is it possible to change radio?
Re: Restricted access changed
I think thats a boot loader thing? But if flashing via recovery can then yes.

Even with the locked bootloader?
Re: Restricted access changed
That I highly doubt

I think this is not network fault..
I think that it happens only when the phone gets hot and the 3G is in use.. It won't happen while I'm at wifi
Thanks Dan to root my phone! It is finally working perfectly now
did I miss something, can you all say if it's the phone or network. Have a dual sim Huawei G500 works fine if both slots uses the same network.But once the other network is introduce, problems!!!

Hi, what i did to solve this is installing phone info and with it i can choose the network type. for some reasons when 4g signal isn't good enough it gives that error so i switch to gsm only and i never get that error in my house wich is mainly where it happens.
hope this helps you.

Can't Register on 3G Networks (Only 2G works)

Just got a Samsung Galaxy S3 LTE (GT - I9305).
And installed MIUI ROM , But my phone can't register on 3G networks, only 2G Network works.
First I thought, it's rom's problem but I think it's not , because I have installed Xposed Framework and tried switching networks with intelli3G, but no luck yet.
Could it be for CSC ?
The mobile was originally bought from UK and I am in Bangladesh right now.
Hoping to get a effective solution .
And Also , I forgot to take backup of my existing rom, can you suggest a original firmware?
Thanks.
Regards,
Shahriar

Hi ,
Can you check that your IMEI exists or not ?
My IMEI was gone , so I have sent the mobile for servicing and rewritten the IMEI, but it seemed that my IMEI was BLACKLISTED!
So , I told him to regenerate my IMEI and it's working fine at this moment .
and he took BDT 400 TK as service charge
If you think you can fix IMEI by yourself , good luck with that , but I wouldn't recommend that as I failed .
So , you can fix yours from a mobile servicing point
Good Luck .
