[Q] Sim issues, trying to figure what's best. - Galaxy S 4 Q&A, Help & Troubleshooting

Have a i9505 worked fine for 18 months, decide to get an upgrade and wifey makes a claim for it. Phone was originally from Carphone Warehouse on Three here in the UK so more than likely unlocked already. Pop her (EE) SIM in and the phone tells me that it's not seeing one installed...try mine again and it's fine.
Grab her a new SIM from EE check that it's working in her phone first (was) pop it in the S4, nothing.
Attack google with all the search terms find lots of solutions! cache wipe - nope, card/paper behind SIM - nope, factory reset - nope. While playing I got the lollipop update! Assumed this might fix - nope. Seen fixes that relate to dropping the mobile network down to 2g or 3g in the settings but this won't work because I can't reach thosde settings while it's not picking up the EE sim.
I've even put in the unlock code from Three (though I think now that this wasn't required) I did try getting into that service menu to remove what ever SIM lock might be enabled but I can't get to it after lollipopping the phone.
It does appear to have a signal but won't text or make recieve calls.
My options are:
Preferred: Root and ROM the phone and not have to worry about it ever again. Not sure this is going to work though, Kinda the reason for the post.
Samsung: Send it to their face and see if they can fix it up, Again not sure if they're going to be able to.
Advice very much welcome!

Problem connecting to Vodafone on SPV M3100

Firstly, hello everyone.
I recently bought the Orange SPV M3100 on eBay, and can not for the life of me get it to connect to Vodafone with my contract SIM.
So far I have:
-Sim unlocked and superCID'd the phone.
-Installed WM6 (via CUSTEL).
-Tried 3 different Radio versions.
-Attempted to install Vodafones official update (which failed for reasons unknown).
-Played around with just about all network settings.
Basically, the device acts as if it's trying to connect to the network, but doesn't (PC speakers pick up inteference etc).
With automatic network selection it just doesn't do anything.
With manual network selection it gives all four big UK providers (allowing for signal - I live in the North York Moors) including Vodafone, but won't connect to any of them.
If I click 'set networks' I get a HUGE list of providers. Vodafone UK (if it appears at all, for some reason O2 and TMobile seem to appear on the list more often) is nearly always unchecked at the bottom. Checking it doesn't fix the problem. When I go back there later it has sometimes lost that setting and Vodafone is unchecked at the bottom again.
I should probably mention that any setting I change here results in a 2 minute "Sending new settings to the network", and on a couple of occasions has caused it to crash.
If I go onto band settings, originally they were both set to auto. Infact, I've just gone onto it as I type, and they have gone back to auto. Before it had got stuck on GSM/UMTS band type 'GSM(900+1800)+UMTS(2100)' (gave an error message unable to change band etc if I tried to change it to anything else). I cannot change the network type or GSM band otherwise without the same error message appearing.
So anyway, as you can see I've gone through a lot and read a lot unlike your typical n00b, and my prospects with this new phone are bleak.
Can anyone help me or suggest anything else that could get this phone onto Vodafone?
I have a worrying thought that this phone could have originally been half-inched (the eBay seller seemed a tad on the dodgy side), been reported, and is now serial-blocked from UK networks, if that's possible?
[edit] I don't know if they are or can be serial blocked, but in which case, assuming you trust and sympathise with my story, is it possible to hack & change the serial number?
Sounds possible that its been blocked. Yes there is a way but you probably won't find any help on this site to do it as it is illegal. Thats not to say you can't search the site, you may find something that may help... Search is your friend...
Cheers...
Yeah reading into the problem reveals a possible 'IMEI' block.
Time to contact the ebay seller I think.
Have spotted an obvious hole in my theory:
The thing came in it's original box (s/n sticker confirmed) with all manuals and accessories.
So back to original problems; is there anything else I have missed?
[edit]
Phone is unblocked according to http://www.amta.org.au/default.asp?Page=405.
So unless they're wrong, why can't I connect to Vodafone and what else can I try?
did you try *#06# on the phone to be sure the S/N on the stickers and phone is the same as the actual phone S/N?
Yes, they are.
Would Vodafone be of any help on this issue?
Depends if they supply that model of phone.
Do you have a network configurator app cooked into the rom you are using or are you using a stock rom?
Might be an idea to look for a network configurator cab if you're using the stock rom and see if that helps. Also if you are using a stock rom, and its not setup for vodaphone, it MAY (don't quote me on this) be affecting the network settings and making it incompatable with the carrier you want.
Just a thought...
I'd also try to run the sim unlock app again, just remember it has to be the SPL that was supplied with the sim/cid unlock tool. Make sure you install Hard SPL V7 back after checking this...
vodaphone will help you if you ring them up using a the sim card in a working phone and ask them to check if its imei is blocked, they do it totaly free of charge.. had to do this with a viewty i bought from a work buddy shorty before he forgot to tell me he did not pay the contract bill and t-mobile blocked it. well annoyed, but they told me it was reported Lost or stolen.
found a few places on the net that offer a check for £10 sod em lol
luckly got me cash back selling it for parts hehe
What a bloody carry on!
Vodafone told me it was blacklisted; reported stolen.
The eBay member is highly upset at being called a theif and very convincingly tells me otherwise (I'm 90% sure I can believe his story, and feel bad for my accusation).
Orange (of whom I'm not even a customer) then tell me "I'm sorry it's blacklisted for an unknown reason ... <click-click> ... there you go sir I've removed it from the blacklist!"
Well, if it starts working again in the next 48 hours I couldn't give a monkeys what's gone on. I just want the bugger to work!
the only reason that a phone would be blocked is if it was reported.......have you tried another sim from o2 or orange etc.
the question has been asked before about imei changing and as you know its illegal,but can be done so if all else fails search elsewhere,not here, i would suggest that unblocking a phone is never likely to be an achievable goal.the networks are not known for their magninimity

How to turn the network lock back on?

Hi!
I have a network unlocked HTC Dream (english T-mobile-version) that I bought used and unlocked. The previous user hade Tele2 as his operator but I used Telia. I´m now in dispute with him because the phone never worked with any calling och messaging but data works fine after manual APN-settings. I have now recieved the unlock code he got to unlock the phone, but with it being unlocked already it doesn´t really help me right now.
The plan is to somehow revert back to a locked phone and unlock it with my SIM sitting inside, and by that maybe fixing the problem.
So how do I make the phone go back to being locked to T-mobile?
Best regards,
Christoffer
It sounds like it might be IMEI locked on the network. T-mobile in the UK will allow blacklisted phones to connect even though they cannot work and there seems to be a loophole where data gets through. Maybe the case is similar, ring your operator from another phone and ask them.

Well I am not sure why you can access data but can't make calls. It would seem to be some type of carrier problem or something I don't know about. I do know that you definitely cannot re-lock it, once it is unlocked it stays that way unless tmobile can do something with it. Something is either wrong with the phones hardware or your carrier, if it is a software problem maybe try flashing a new rom and re-enter your APN stuff.
Try making a emergency call like 911 or whatever, if that doesn't work something is screwed.
I tried it out this weekend with a friends SIM who is on Tele2, and it worked there with no problem! It is so weird that it acts like it was network locked, even though it shouldn´t be.
I´ve seen that a few have posted about the same problem, mainly with the Dream but also with the Magic. It comes up as "Telia" but follows with a "(No Service)". About 24 hours after I recieved it connected to the network and worked fine for about 10 hours but then it stopped working just as I got a MMS I was about to download. If I try to manually connect to the network from the list of operators, it says that my SIM "isn´t allowed to connect to this network".
I´ve downgraded and upgraded Radio to try to solve this, nothing worked.
I dont know alot about foreign networks but if you can get data then you should get all services. That message you got "SIM isn't allowed to connect to this network" is what you should get when your not unlocked. Or if the SIM is trying to use another carriers cell tower, your sure you got the APN settings correct? It sounds like you have some sort of hardware problem if the switching of Radios didn't help. Can you try the same SIM in another phone and see what happens?
I use the same SIM daily in my old phone the Dream was supposed to replace, works like a charm with everything.
It can´t be a hardware problem when the phone works flawless with Tele2, or can it?
Well it is just weird the data works and not calls. I am just guessing what it could be. Maybe something with the carrier? It's a odd problem.
Did you ring your operator? Put the SIM card in the phone, turn it on, then ring Telia from another phone. They should be able to tell you something. If it is blacklisted, they do not always share this with other networks.

That might be a thing to try. I have been in contact with Telia and gave them my IMEI-number but even during the short period the phone worked (by chance) they say that IMEI has never been logged in their system.

HTC Hero + 3 Sim = No connection

New Hero. Originally sold by Orange UK. Unlocked and imported to Ireland.
New sim from 3 Ireland.
Sim goes into Hero, but Hero does not connect to network. Occassionally phone makes brief connection to 2G roaming partner (Vodafone), but never 3G connection to 3 network.
Manually search for networks and select 3 (or any network for that matter) and phone says "Your SIM card does not allow a connection to this network".
"Mobile Network - Connect to internet" option in settings seems disabled (greyed out, can't be changed).
Have tried HTC, Orange, T-Mobile and MoDaCo ROMs.
Can anyone please suggest a fix. This is surely a phone setting thing? It can't be that 3 USIMs just don't work in the phone can it? I mean I haven't got the APN configured properly, but I should still be getting basic phone services no?
Did you get this fixed? I am having the same problem trying to use Three sim in England on a Orange Hero. It accepts the network unlock code but then stays on the 'unlocking sim' screen and I left it for ages.
No. Gave up and am staying with my old provider (3 didn't seem too interested in holding onto me as a new customer).
I've been posting this query in a few places. In one thread a guy from England said his 3 Sim used to work but then suddenly began exhibiting the behaviour I have described. I think he said a factory reset fixed it. Anyway, some have supposed that this could be a bug in Android/Hero that makes it incompatible with 3. I personally suspect its more about 3.
Thanks anyway. There must be a way round it, I'll find it.
Be sure to post if you do.

This is MAJOR weird. Chances are, the new USIM is not compatible. I've got mine for about 2 years, first in a W910i, now in Hero (sim-free, UK). Everything worked first time in the Hero, just needed APN settings for MMS and data. Surprisingly, MMS won't send or download while on WiFi. Mine's currently running on the leaked 2.73.405.5 ROM (not MoDaCo).
Maybe try someone else' sim, from 3 or other network and see if that works.

Well I've never actually unlocked a phone myself so I don't know, but of its hanging then I would guess its not unlocking properly so its not going to work.
Maybe contact the person you bought the code from and ask for help or another code. Otherwise I wonder if reflashing the ROM would help?
Hero on 3 Ireland
I am using a 3 Ireland "3pay" prepaid SIM with my white Hero (completely unlocked, imported from UK). Works fine! I got the "mobile broadband" prepaid package about a year ago and had to buy a usb modem (sitting on my desk ever since) with the sim card.
You need to enter the 3ireland.ie APN, but no other magic incantations
Occasionally, I get the "Roaming" indicator in the notification bar on the Hero (weak signal might cause this). Then, clearly, no internet. Its not roaming with another provider either. I strongly suspect that this is a 3 bug. Reconnecting to the 3 network fixes it.
PS: I'm in Dublin and usually get a HSPA connection ("H" icon)
PPS: You do not need to top up your 3 sim in order to connect to http://my3.three.ie (indeed, on that web page you can enter your prepaid voucher #).

Hmm, you guys seem to have some strange issues with those 3 USIMs. Maybe checking serial numbers or chip revision would shed some light into this. My USIM is not only working fine, but also happily roaming (GSM + data!) when I tell it to do so. Heck, I've spent two weeks in Italy on "3 Italy" with this USIM and it worked fine.
Ok since posting on here yesterday I have rooted my phone and put on modacos latest rom and its still not working, I have tried two seperate three sims and a vodafone sim. Given that the vodafone sim is also not working Im thinking it's a problem with the unlock code.
I'll contact them and see what they say.

Maybe I was not clear enough: Every couple of days, I get the roaming indicator while being in Ireland. Clearly, you can't roam to another Irish network. While I haven't tried it yet, I'm pretty sure that roaming outside of Ireland will work (worked before I got the Hero).

It looks like we have the same problem.
As I promised above, it is the detailed description.
First case:
Turn on the phone with orange SIM card - everything works fine.
Turn on the phone with any other SIM card (I actually tried 3 other SIM card from 3 different providers). It asks unlock code. Enter unlock code I bought (actually any code containing 8 digits) it says "Network unlock successful." But after that it allow only emergency calls and if I try to make a call I see "Not registered in network" message. After reboot it asks unlock code again.
Second case:
If I do "restore to factory defaults" and turn it on the first time with my (no orange) SIM card, it asks unlock code I enter correct unlock code (salesman gave me one, and after that I also bought the same code in the Internet )
it hangs with phrase "Unlocking SIM card...". (Actually "turn off menu" works, I even can make an emergency call, but that is all I can get from it)
Also I noticed that in the first case there is strange line on the bottom of the screen (of the size of the notification bar).
I have tried different ROMS (original, rooted, latest, modacos) all the same. I only didn't try to downgrade radio firmware. I don't know if it can help. I upgraded to latest one even before I get the unlock code. As I already mentioned I also tried all SIM card I can obtain, the problem is obviously doesn't caused by SIM/Network incompatibility. Btw, my SIM card works OK in another HTC Hero (which was bought with my one).
I think it is problem with unlock procedure itself, not with code correctness. If wrong code entered it must say something like "wrong code", but for any 8 digit code it says "Network unlock successful". Is is the symptom! )
I do not know what to do further
Ok, I have now had a reply from Unlock Now, they said it must be an issue my phone (although we have now established it's an issue with orange phones) but they did refund my payment.
I'll keep looking into this and post back if I find anything out.

I bought the same unlock code on two different sites, finally both did refund It is OK, but what will we do further?
I've decided started a new thread (http://forum.xda-developers.com/showthread.php?t=560105) as I don't think it is just a problem with Three sims as the Vodafone one I tried didn't work.
I'll still post back here if we get any useful info.

NOOB - T-Mobile UK HD2 unlocked - no O2 connection..

Hi guys.
Really sorry about this but I am at the end of my tether with this!
I run my own IT support company and one of the things I do most is Blackberry and iPhone Exchange email syncing. While both of those work brilliantly, I have had users having loads of issues getting their Windows Mobile devices working easily. Luckliy only one or 2 have these devices but more are asking....
I resorted to retiring my Bold 9000 and got a brand new sealed HD2 on the UK T-Mobile network today. First thing I did was get a sim unlock code and that went through first time (using my working o2 SIM from my BB). However, I couldn't make calls so after I spoke to o2 I got in to the Phone, Network settings and with the Network selection on auto, the preferred networks list was blank. Clicking the preferred networks button brings up the list of preferred networks, ticked o2 - UK and ok'd it. Goes back to main network screen and still blank. Clicking Find Network then brings up cannot register on selected network.
Changing automatic network selection to manual, selecting )2 - UK and ok'ing that brings up the same 'cannot register on selected network error. So, after coming here, I stuck on the HSPL 1.42, then upgraded to RUU_Leo_HTC_WWE_1.48.405.2_Radio_Signed_15.28.50.07U_2.05.51.05_2_Ship
That went on fine and after wiping to factory to make sure I sent through the set up. Same errors and still can't make receive calls.
Stuck on the 2.08 hspl for the hell of it then upgraded to RUU_Leo_HTC_WWE_1.66.405.2_Radio_Signed_15.30.50.07U_2.06.51.07_Ship
Guess what? Exact same problems! I spoke to o2 support and they were pretty useless. Explained that it was sim unlocked and on a generic firmware. They said that T-Mobile do something weird with the HTC and I should try calling HTC tech support, who are now closed...... I am not sure HTC will be of any help anyway as I can't exactly go telling them I have stuck on the HSPL and a non-approved firmware for what was the originall carrier!
Help please anybody?? I have googled and googled but haven't found anyone with the same problem, I might be being blind. BTW, what I guess is the antenna icon has an exclamation next to it
Thanks,
Nick
Quick update. Housemate got back so I nicked the Vodafone UK sim from his iPhone and stuck that in the HD2. Same problem, won't register on Vodafone either. Anyone?
Got annoyed. changed the SPL back to the standard 1.42. Installed the latest T-Mobile official firmware. Same problems. Do I have the only HD2 ever to be doing this? . I don't have a T-Mobile sim to hand and the nearest store is miles away sadly.
Does your phone app not work at all ?
How do you know unlock code worked ? so far every sim you tried has failed.
Where did you get the unlocking code from ?
How did you use it ? meaning how did you input it ?
Verdict so far, if a t-mobile sim card works then unlock was a fail !
Ok referring to your network selection, for the UK, you should have it set to Automatic, it will then use the network associated with your sim.
referring to your call problem, does the phone still work with the original t-mobile sim?
if so it sounds like your unlock code didnt work.
if your phone no longer works with the original t-mobile, I should think something has gone wrong with the radio software you have installed on the phone. Try going back to the stock htc/radio rom. If that doesnt work then the phone probably needs to go back to t-mobile for repair, at this point you tell them "it just stopped working"
have you tried to run the connection setup wizard?
settings - menu - all settings - connections - connection setup
if there isn't one, connectionsetup is available as a cab.
Hi guys. It was a brand neww, sealed box HD2, but from T-Mobile. No SIM with it at all or I would have been trying that too of course .
Regarding how I unlocked it. I paid an ebay seller to give me an unlock code. When I fist put on 02 SIM in the phone it wafffled on about being network locked basically and had a field to enter the unlock code. Entered the code given to me via the Ebay unlocker and never got that message again on the screen. Is that wrong somehow?
Manual network, auto network, selecting carrier etc all of them make no difference. I am off out now but have found a local store with PAYG T-Mobile sims in stock so will grab 1 later today and see what happens then.
Will update/bore you all later!
Cheers,
Nick
Right, case closed. I got the T-Mobile sim and stuck it in. Showed up with T-Mobile on the scren and a good strength signal. Tried to make a call, dropped back to the home screen almost straight away. I had full data access though. Spoke to T-Mobile who informed me that my brand new, sealed box HD2 was blacklisted and I could do nothing with it!
Vodafone and O2 just flat out don't let you register the handset on their network if is it blacklisted it would seem.
Contacted the seller and he has arranged a refund, but the refund is showing as 'pending' so I am not going to return the phone until I see it physically in my account.
I have to be honest and say that this is actually a good thing as despite HTC doing all they can to make the Win 6.5 on there look less dog-like, the overall UI is still pretty awful. Now,this phone with Android 2.1 on it might be a dfferent matter! Back on my Bold 9000 for now......
Cheers,
Nick.
I am sorry to hear about that, looks like to you got hit by some sort of scam, probably resealed a second hand or refurbished unit into an original box and sold it as new.
regarding the UI of the htc devices, I am not really sure why you think this, htc hd2 uses htc sense which is the same ui as on the android htc phones. The only windows mobile thing you should really see is the start menu which has been praised as being a very good replacement for the old start menu. even all the settings windows are run through the htc sense ui so i am really not sure what you are complaining about :S
If you dislike the top bar/bottom soft buttons, there have been a lot of modifications to these in more recent hd2 roms, maybe you should to take a look at the roms section to see some pics.

Phone Not Allowed - UK SM-G950F

Hi All
I'm at my wits end with this Samsung S8 phone, Bought a 2nd hand S8, was working fine, but I noticed the internal storage was only showing 9.63GB
Had a look on here and the solution was to stock flash the phone. I did that, all fine, storage was back to normal....BUT since then I can't make or receive any calls.
I get the error "phone not allowed" and it won't connect to ANY mobile network.
I've tried loads of different suggestions
Sim is OK in another phone
Re Flashed (numerous times)
Andriod 7 and 8
Sim and Phone OK with three network
But still have the issue....
Can anyone help me? or push me in the right direction?
Cheers
Tommy
You probably tried this, but try booting into safe mode. If it works then there is a software problem. If the problems persist in safe mode you probably gotta contact Samsung.
Are you sure the phone is unlocked?
Sent from my SM-G950F using Tapatalk
Is the phone blacklisted? if it is blacklisted then it will not connect to service. Your SIM wil work perfect in any other phone.
Hate to say this but it does sound like your phone has been blacklisted.
You can check with one of the online IMEI blacklists.
If your phone shows Phone not allowed and a code like MM#6, it usually is an indication that it was blacklisted.
Check your phone's IMEI on a blacklist checker like http://imeipro.info/
The previous user most likely had the firmware and baseband messed around with and once you flashed stock it reverted to true state, it's highly advised to get back in contact with the person, where was the phone bought? A shop? Online?

Yeah tried that , still the same
If one is in possesion of a S8 that says "Phone not allowed", and the phone is blacklisted, is there any way of fixing that?
I have the same issue here..
I bought an S8 from Manchester last summer, and I started using it last week, (because my other phone worked longer than expected) and after I gave the phone the Network key that the previous user wrote down for me, then that message appeared.
So im stuck with this almost completely new brick aswell...
Any options at all?

So im stuck with this almost completely new brick aswell...
Any options at all?

The only real solution here is to either go abroad and sell the phone, or sell it to someone who is going abroad. The phone will work outside of the UK.
It does sound as your phones imei Nr is blocked in UK.. Probably the person who sold you the phone, stole it somewhere.
I have the same problem on my Samsung S7 now in Brazil.
In Canada, on Canadian carriers, everything is fine, and if I put the Canadian SIM in there everything is fine. But the minute I plug in Brazilian SIM card, boom, Phone Not Allowed message comes up and it won't connect to any of the Brazilian networks. Brand new SIM, works just fine on another LG phone (and any other phone I tried).
The phone is unlocked, I even checked with a few pieces of software and there is no network lock on it either.
I've got the master & network unlock codes from Samsung, but have no way of inputting them as no prompts for those come up when I insert the Brazilian SIM.
I checked the IMEI, it is definitely clean and not blacklisted.
Heck, I even rooted the phone to see if that would help, and still nothing.
Any idea what else to try or what else might be causing this goddamn message to pop up?!
I solved my S8.
Blacklisted on all uk networks except Three network.
Works perfect.
