Hi guys, I've just got my replacement SIM card today but there is no signal for the SIM on my Galaxy SII Gingerbread 2.3.3. I popped the SIM into my old Nokia phone and it is working fine so I'm pretty sure it's not the SIM. I googled and looked around the forum but found no solution. Already message the carrier and they say the phone is not barred while the SIM is working fine on my old Nokia phone.
In the "About phone/Status" the phone number is unknown, network is O2 UK, signal strength is ok, mobile network type is "HSDPA", service state is out of service. IMEI number is normal. When I dial any number it says "mobile network not available".
If this thread existed before, I really apologize for making a new one. Any help is really appreciated
Have you entered the network details in the phones settings ??

Where'd you get the phone? Sounds like it's a SIM-locked phone...

I believe you're referring to the 3g network? If so then my problem lies in calling and texting itself. There is no network signal as there is only a circle with cross. If not, how do you enter the network detail

This phone is an international version I got from my home country Vietnam and it's already unlocked. I was using UK SIM fine until the December holiday. After I returned from Vietnam, the SIM stopped working and I ordered a replacement. Can flashing new kernel affect this cuz I tried some new one during the holiday? The IMEI is still normal though, I checked
i have a problem ...
with miui or wiui , my debit of 3G is bad. I download at 20 ko... with official rom i download a 300 ko ...
why ?

Have you tried the SIM in another phone? Or a different SIM in this phone? Could be either the SIM card is bad (which the replacement SIM will fix), or the SIM card slot on the phone went bad (which the replacement SIM WON'T fix).

Kind of rude to hijack someone else's thread... But I'll answer anyways. My guess is that your official ROM has modems more suited for your country and carrier, and MIUI (or WIUI - never heard of this one) doesn't. You can probably fix with flashing a different modem. But I can't tell you which modem to try.
I have always try e few modem and it's doesn't work .

Try some more. I doubt you've tried them all. Maybe some kind soul who is also on your carrier (which you have displayed on your profile as Orange) in your location (also in your profile as France) can tell you which one.
I popped the SIM into my old Nokia phone and it worked fine so it's not really the SIM. I was thinking maybe there is something wrong with my software but you brought up a good point about the SIM slot I'm gonna try it out and see first
ok . i will try another modem.
thanks
no, it doesn't work ... i have tried a modem who is ok with checkrom or ics or official samsung but don't work with miui . it's strange because it's ok with miui NDT
I have not moved or changed locations or anything but after updating the newest samsung firmware (on friday) my phone is now 100% of the time roaming. I've checked the network settings and it says Tmobile in there as it should (i'm on Tmobile in america with the i9300).
Is there something i did wrong? I updated it with Kies, what can i do to downgrade back to the old firmware if i get tired of this roaming business?
try changing your modem

How did you be able to update your i9300 cause i am using i9300 and t-mobile as well. But no update for me at all.
I am located in NY btw so do you think I have to wait or not gonna get the update at all
Edit, Just updated mine via odin and working good

I am not sure, but its funny my friend has the BLUE i9300 bought 3 weeks after mine, and he was not getting a notification of the update via kies either, but it did give it to me and my phone the exact day it was out (uk firmware).
about changing the modem, will I need to root for that? i prefer to run stock for now..
that's bizarre but it probably has something to do with the phone being an internation model with a uk csc, but i've used my S1 from the uk several times in the u.s. with t-mobile and never had that problem .....can only assume it is a bug

Yea becuase when the phone arrived it worked great (even had a minor firmware upgrade the day i opened which was like june 15th ish or a few days later) and still worked great, no Roaming at all, then with last weeks update now it roams
It's worth pointing out that changing the modem will not work as a valid solution in this case. If one uses a non-LFB modem with the LFB ROM, the mic doesn't get used. One would have to also go to an older rom in addition to a different modem.
I'm having the same exact issue.
Need a solution.
Tried a factory reset. No dice.
Hi guys,
Didn`t find answer for my questions, so decided to link myself to similar topic.
Since the SW update I have done today my phone doesn`t lock to a network
When I go to settings to find a carrier manually, It takes about 2 minutes to find 4-5 networks available around, I am picking o2 UK (as I have a contract with them) and it says : Registering to o2 UK which takes about 4 minutes. After this it says : Emergency calls only and there is no status bars at all.
Master reset didn`t help.
What steps should I take ?
For you reference :
- Phone took from CPW in UK as sim free
- SIM Card used is from o2 UK (contract)
- I don`t want to flash anything, I would like to stay to stock ROM (if possible)
UPDATE : Chosen `Select Automaticly` allowed the phone to find signal, could make a call etc, but after 30 minutes lost signal again....

I did find out that the CSC that was applied by default was KOR. I went in and changed this to BTU using *#272*imei#, but still did not solve the issue.
Wondering if a repartition would help?

If u do not wish to root then your only option is to take it back to the store, so they can fix, u bought the best smart phone available on the market and u can't make phone calls or browse internet(without wifi).
To my understanding, still no resolution on this..
My friends phone after being updated (he just got his first update after having the phone a month) is now roaming as well.. So this is definately something either with our network (t-mobile) or the recent updates.
I've just started living with it, but it sucks becuase it does silly things like makes me click 'download image' when someone sends me a picture message in text...
with the few bugs could be ironed out of this phone kinda frustrating.
I do have similar problems since I installed an update 2 weeks ago. at home the phone says it is roaming at work approx 6 miles away and with a different station I am connecting to it is fine.

Thats interesting, no matter where I go i get roaming. Though a few times I have gotten the 'roaming' warning popped up, so maybe i went out of roaming and didnt know it? I'll keep a closer eye on it.
It is very frustrating and annoying. I've called T-Mobile and they said they would open a case with Samsung. If you guys could call too, we might get a fix.
I really suspect it is something in the CSC. Maybe if we could get the T Mobile SIII CSC and apply it?

My suspicion is wrong. I pulled the TMB CSC from a T999 ROM and manually copied it to /system/csc/TMB, then used the CSC Selector App to change to TMB.
No dice. Still in Roaming.
Hi everyone,
Everytime I open the phone I'm asked to enter a Sim network unlock PIN.
At first I talked with my carrier, which tried to give me few PINs to unlock the network lock, but none of them worked.
After reading a while on the internet (and also as it says on the box) I suspected that this is about the Region Lock samsung implemented in it's new devices.
I bought my device in Europe (and well, I don't live in Europe).
I talked with the shop I bought the device from just to make sure the device is not sim locked, and they claim that they indeed sell only sim free devices, so I turned to Samsung.
After talking with Samsung in the country I bought the device, I was given an unlock PIN, but unfortunately, it doesn't work.
Do you have any idea what could it possibly be?
Maybe I tried too many times wrong PINs and the network is locked now? Don't know already....
P.S.
All the phone features works fine (if I go out of the screen with the PIN request), except for mobile internet and calls of course.
Images attached below.
They claim wrong that my friend is sim locked & you will need to find out what carrier its locked to, that carrier will have specific codes.
At least that is my understanding.

Thanks, but based on what info are you so sure?
I talked with the shop again and they INSIST their devices are sim free.
I need to have some kind of proof to argue that.
And also, I'd like to hear more opinions please...
BUMP - any ideas please?
Have the shop were you bought it from replace the phone or you can call the carrier that the phone is lock to and request the unlock code. It should be very easy to determine that by firmware build number (For example: G925P is Sprint)

Just confirmed it's a G925F... so it's not sim locked, as the shop stated.
This phone is simlocked to a network. You need to find out what network it is locked to then get a unlock code.
Once you enter an unlock code it will be unlocked to all network....

Ebay is a cheap place to get unlock code but you NEED to know the original network

Why can't it be? that is a model number for UK handset but it doesn't mean anything else. All UK and europe (also middle east) models are G925F , some are network locked and some are not.
Accept it and do something about it. Ask for refund or ask the seller to get you unlock code.

Ok thanks. Thought all G925F are sim unlocked and cannot be locked...
Is there a way to tell the network it's locked to? (because I know what the shop is going to say: "no, its not unlocked so we dont know the network...")

Your phone is regionally locked., which means you should unlock it with a Europian SIM card before using in an other country.

What you need to do is check with the shop where the phone came from? Which country the phone was bought. Once you know that you can try different sims (they are freely available from providers or ask your friends). The unlock code is a combination of Phone IMEI number and the network so you need that information.
Let me know how you get on...
I have an unlocked UK find X2 pro and I don't feel like going through the switching region process just to enable the dual sim. I already purchased a dual sim tray for this.
So I found this old reddit to enable this manually for a Samsung phone using tasker:
https://www.reddit.com/r/tasker/comments/b0a1o5
Now I would the need the help of someone with a dual sim OPPO phone (probably better if its a X2 Pro) and monitoring enabling the second sim with adb shell settings list system
Any volunteer?
This probably worked on older android and is samsung specific. Chances of this working are really low but I guess someone could give it a try.
But, I did notice if you unlock your phone using the method in "Change region" thread instead of actually changing your region try typing "*#*#4636#*#*", go into "Phone Information" and see if you can toggle "Enable DSDS"

All models of the X2 Pro are dual SIM. Just the functionality has been disabled by Oppo in the EU because of GDPR.

That's after unlocking the phone with the "Sec5.exe" way from the "Change region.." thread right? Not talking about SIM unlocked(international) phones.
The change happens after you select another region not after you unlock the phone using this method so if you wanna keep everything the same you just unlock it without switching to Singapore.
Oh I didnt know there were 2 types of unlocking. My phone is SIM unlocked yes I bought it from an official UK retailer directly.
Would this void the warranty?

You should probably read through the other threads here. We don't know but we speculate it doesn't as it's using oppos own tools to flash official roms.

The problem is, I am not in the UK, I ordered the phone from the UK, but in my country, we don't have an OPPO service center.. :/ So that's why I am asking for a self-service way to do it. I have installed custom ROMs to phones before, I quite know how to do things here and there.
@AnthonyMkD even if there are no actual Oppo Service centers where you live there probably are some sort of service providers/companies which act as Oppo's official service partners and do all the repairs for them. They should be able to do that. It's the same where I live.

I just received my Xperia 1 IV USA version today from FocusCamera.com today, I was a little skeptical if it was even the USA version, since it wasn`t shipping from Sony until next week, I originally had pre-ordered on Sony website, then with a little looking around I had found the USA version on ebay in-stock, then I saw the seller name and went to there website yesterday and verified with there live chat that in fact it was in stock and would ship, so I ordered and use next day air shipping, everything works flawless and actually has the 5G bands like my Pixel 6 Pro, so I can get proper 5g speeds, on Band N71, That was missing from the Global version I was using 2 weeks ago, now I need the Firmware from Sony so I can root. I`m a happy camper

I guess you were not able to root it?
To know exactly how capable the device is then its necessary take modem logs and let smart people parse it.

Unfortunately not, so this will be going back for refund, I can`t justify spending 1600.00 on phone and not able to root and do with it what I want with it, but there`s always the global version I could go back too, I`m going return it and wait and see if Sony does eventually allow it to unlock the bootloader, until then I`ll just use my Pixel 6 pro for now.

Should be both on all versions, USA model difference is mmWave support.

You can know that without buying phone. Download the firmware with xperifirm, extract modem.img and use ELFextract to extract your hw variants .mbn file. This will reveal the carrier/band policy files (in policyman folder) which live in the modem. There you can see which bands are enabled for specific operators and if they are enabled for SA and NSA.
