Need Help: the sim card is missing

Hi,
i've new problem with my S300+!
Yesterday my phone worked well, today I see the following message:
"The SIM card is missing. You can still make emergency calls if your service provider supports it".
I tried to switch the sim card to another phone and the sim works correctly, then i tried to put another TIM sim card on the s300+ and the message is showing too.
What's happened?
Originally the s300+ was SIM locked for SFR sim. But when i bought it, it was unlocked to sim free.
Two weeks ago i've upgraded the radio rom to latest version.
Reading the other device's forum, i've saw that problem may be an hardware problem. How can check if the problem is caused by hardware ?
Can I try to re-unlock the phone? or it is effectless?
Thanks in Advance!
can you try a SFR sim in the phone?
see if it works on that sim.
do you know the person you got the phone from?
how was the phone unlocked?
you could try unlocking the phone again.
I can't try a sfr sim!
I'm in Italy and I've bought the phone in France.
I don't kown the person that have sell the phone, and i don't kown ho the phone was unlocked.
I know that the phone works well for 3 weeks and then not!
I 'm tring to reunlock the phone.
if you do a search on this forum you will find the files needed to sim unlock your phone.
when you have done, may be your phone will be ok again.
On the down side to that may be the person that sold you the phone has reported it lost or stolen and its been blocked/locked if that is the case i dont know what you can do.
I have just unlock the phone, but nothing is changed!!!!
I've also checked my imei on this site:
http://www.amta.org.au/default.asp?Page=405
and it not seems reported as lost or stolen...
I bought a S300+ (SFR Locked) in January 2008 and I unlocked by myself using tools found on this board, it still work fine but with a Vodafone Italy SIM, but sometimes I use a TIM Sim too.
I don't think that your is a lock problem, from the message you get at the powerup sound like an hardware problem but you should try an hardware reset how last option if you didn't it before.
I've made an hard reset, but nothing happens!
Also I've tried to flash a new roms (an italian rom and the original rom), but was not the solution!
I'm not sure where is the problem, because the phone worked well for about 3 weeks, than suddenly shows the missing sim card message....
IS there a site to verify if the imei is blocked? i've try www.ama.org.au
Is There a program or a tool to verify the integrity of hardware, especially for ths sim hardware? or a datasheet of sfr 300+?
I've had the same problem on my trinity and it turned out that I needed a new sim card because the old one burned out after four years of use. This may or may not be your problem.
I solved my problem by inserting a little paper between the SIM and the support lol

unknown sim error

Hi,
I have a locked Spanish xperia x2. Following the suse update procedure reported in the forum I managed to load the GENERIC_UK_R3AA035_CABS.rar. After alla the cab installation the langauage is finally English but X2 gives me “unknown sim error”. What I am missing? thank and regards

Does the sim card work in a different phone?
Can you get a replacement sim card?
I remember that I had some issues with my phone one morning and I happened to walk by an official T-Mobil store while in downtown Chicago. It turned out that a number of specific, older, sim cards did not work due to an update on the network. So the T-Mobil guy just copied my sim to a new one and i was on my way with a working sim/phone.
One small point to know: I had the sim card for about 8 years. It was still Voice Stream (now T-Mobil). So it was a really old sim.
I have 2 new sim card working perfectly in my old X1. For none of them I have to insert pin code in X1.
In X2 I insert the pin code and then receive the error message. May this be due to the fact X2 was locked?
But shouldn't have been the loading I did of
GENERIC_UK_R3AA035_CABS.rar.
unlocking it?
what am I missing?
to unlock my X2 is GENERIC_UK_R3AA035_CABS.rar enough or should I purchase on the net an unlocking code?
thanks
no, you have done everything right so far. now just do the sues upgrade again and it'll boot the english rom (based on what cabs you downloaded on your phone) and your phone should be working fine. tell me how everything turns out. and good luck

Flashing a different language/rom has NOTHING to do with the fact that your phone is SIM LOCKED. And it will stay sim locked until SIM is UNLOCKED. But not with flashing a language or rom or anything via SEUS.

Network Detection Issue

I received a unlock code for my phone and when i put a sim card for other network it is not detecting any network but when i put the sim unlock code phone is accepting it and telling that phone is successfully unlocked.
Can someone help me how can i resolve this issue and be able to use my phone on other network other than TMobile
I am trying to use the phone on Aitel Network in Delhi India - FYI
Reboot the phone after you've unlocked it.
If it boots locked again - there's your problem.
If it reboots unlocked, but you still see no data - you might have a HW issue with your phone. Looking at your carrier supported bands, the phone should work with them. Verify that you have a good signal in your area.

If you still having problems just root the phone using the gfree method. It will unlock your sim

3g/4g doesn't work on Samsung On5 SM-G550T1 MetroPCS

This device was bought outside India (I'll ask my friend which country if that's necessary). It was probably bought with MetroPCS sim. Now when I insert Indian sim I can only connect to 2g network, when I chose 3g I lose connection to the network.
So I figured this device is locked. There was this app provided by MetroPCS that provided a way to permanently unlock. I checked their site and it's stated that if your device meets all requirements (use their sim for 180 consecutive days etc) then your device will be unlocked for free. I tried unlocking through t that app and it was successful which means my device was eligible. It still didn't work.
So then I thought maybe changing ROM will solve this issue so installed TWRP and flashed custom ROM. Still nothing changed.
That made me think it's locked due to my imei. I was left with no option but to change my device's imei (I know it's illegal but I wasn't trying to change it to some random imei to hide identity or evading ban from MetroPCS) so I rooted it and tried Xposed framework. When I finally installed Xposed and got this module to work, i was still unable to access 3g/4g.
I've tried everything I could think of and still couldn't get it to work. Please please please help me, I am exhausted.

Your radio/modem probably needs to be changed from one for the US, if that's where your phone was bought, to the one for India so that you'll be using the correct baseband. Search for a flashable one from one of the threads for the Indian variant. That would be my next try anyway.

S10 + Sprint Unlocked issue

Hi Everyone,
I just bought a brand new s10+ from marketplace. I ran a full imei report and everything is clean & not blacklisted. It was a sprint phone however the provider I use is consumer cellular (uses ATT towers). When I put my sim card in it obviously said invalid sim and request it get unlocked. I wasnt concerned because I was going to convert it to unlocked anyways via odin like I did my note 9. I reflashed it via odin with the u1 firmware. However the same thing is happening it keeps saying invalid sim and the button for mobile operators is not showing. I have a tmobile sim card and if I put that in it works fine. Being though tmobile and sprint are the same thats why it works fine. I also have a ATT sim card, If i put that in I get the same invalid sim message. So it still appears to be locked somehow. Only sprint / t mobile sim works. I thought by reflashing to unlocked it would unlock the phone sim.
Just to be clear the phone is brand new and never was attached to any account.
Any ideas? I dont know what to do here.
Thanks!!
As I understand, phones that are locked to a network are not just software branded... also the phones hardware ID. So flashing a generic firmware is not enough. You need to get the phone unlocked from the phone's original operator
I found out what I had to do. I had to use a remote unlock service to remove the software lock on the phone. Its fine now. Thanks
