Galaxy S3 clone Sim detected but no Service - General Questions and Answers

I bought a Samsung Galaxy S3 clone (unlocked of course) with Android 4.1 and an MTK6577 processor. When I put in my sim card it's detected as a T-mobile SIM, but then it goes to NO SERVICE. It, however tells me I have a New voicemail, which I confirmed by placing the SIM card in another phone. Is there any way I can fix this?
Thanks!

[Q] Not Recognising Sim Card, Any FIx?

Hi All
I have a Galaxy Tab 2 7" Model GT-P3100 I have not used it very much as I mostly use my S3. I bought it from Hong Kong, when it was tested in the shop in HK there was no issue with anything, all worked fine. I have since brought it back to England, mostly used it on wi-fi at home, then recently I decided to get a sim card to put in it to use it out and about.
When I put the sim card in, it comes up with a message box "SIM card added - Restart your device to access the mobile network - Restart" so I click restart and wait for the reload. But it doesn't recognise the sim card and still has "No SIM - Insert SIM card" within the notifications box as ongoing.
Now if I remove the sim card from the device while it is still on, it comes with a message box "SIM card removed - The mobile network will be unavailable until you restart with a valid SIM card inserted - Restart"
This sim card I am using has been tested in other phones and it works no problem, it is a pay monthly contract with Orange. I have also tried other SIM cards in this device and have the same response from every one.
So after doing some reading online and on this forum, I rooted the Tab and then used GalaxSim Unlock to unlock the phone, thinking it may be becasue I bought it in Hong Kong, the Tab is now unlocked but still shows the symptoms above.
Is there anything else I can do to get it to recognise the SIM or do I need to unroot it and send it back to Samsung?
Any help is gratefully received.

flash a custom rom ( stable is cm10.1.2) or a customised stock rom.I thinks it will fix your prob
It is not a ROM related problem.
Go to your network operator and have your old sim card replaced with the new one (with the same number if you want). Sometimes, an old sim card just don't work with newer service. G' luck..

Thanks to you both, the sim card is new, only 2 months old. I have just flashed CM10.1.2 and not only does it not recognise the sim card, I also can't do anything as the android keyboard crashes all the time.
I am going to try to reboot with the latest nightly to see if that helps.
I am now running the latest CM 10.2 from 21.8
The SIM is still not recognised and now my PC is not recognising the Tab either.
When I first plugged it in it came up with installing drivers for Google Galaxy Nexus?? Is this normal
Hi this is the same problem I have on mine,I am starting to think it is the card reader that is the problem ? which wont be a easy job to replace for me
Might be hardware problem
use triangle away to wipe binary on downloadmode then install a stock rom and contact service center to repair it under warranty (if your device have warranty)
Just flash a different modem

[CLOSED][Q] Unlocked Relay getting no signal on a non-TMo carrier

EDIT: No feasible solution found, so I had the device sold. Question closed.
UPDATE ON THE ISSUE: It seems that it would not recognize WCDMA networks (GSM works properly), hence no signal on my WCDMA-only SIM card. Any ideas?
Hello all, new joining the Relay 4G forums
Long story short, so I got my Relay 4G today, but it just wouldn't fully recognize my China Unicom SIM card. Symptoms and information:
1) No signal
2) Correctly displays my carrier's name, but says "emergency calls only"
3) Can search for available carrier networks, including China Unicom, but fails to register on the network - it says "unable to connect, try later"
4) The device has a correct IMEI instead of a generic one
5) Doesn't prompt me to enter SIM UNLOCK CODE when I first plugged in the SIM card
6) SIM unlocking procedures posted in the forum doesn't help - the phone should be unlocked when I bought it
7) It recognizes another SIM card from China Mobile (WTF!!) and works properly
8 ) China Unicom uses the 2100MHz band, which is supported by Relay 4G
So now I'm out of ideas... Any help would be appreciated. Thanks

...So this phenomenon means this really is SIM-locked? Good, I'll revert to ICS and try unlocking with that method...
One question: why doesn't it prompt me to enter unlock code when I inserted the SIM?
@croogrog It didn't turn out to be that simple... SIM unlock procedures didn't work at all even though I got all the timings right. I think the problem isn't caused by SIM lock... But what can it be?

More strange symptom: another SIM from China Unicom got recognized quickly after I inserted it. I don't understand this...

If other SIMs are working and you are able to call someone your phone was unlocked when you got it.
If your SIM isn't working it could be that you need a new one from your provider.
I had that problem years ago. My phone was too new ...or my card too old.

From a local importer at TaoBao (China's equivalent of eBay).
UPDATE ON THE ISSUE: I changed my SIM card for a new one at my carrier's but still won't recognize. Adding in the symptom that it can recognize another China Unicom SIM, I guess I can conclude that the problem lies within this particular SIM.

Best test would be to try another carrier sim all together. Not china unicom. See if the phone takes it. That way you will know for sure that it's unlocked and works. Unfortunately, there's no way to check if it's unlocked, other than to test sim cards
My next suggestion would be to consult samsung for a warranty repair, because your phone might be faulty. Or consider asking the seller that you got it from to send you another one. Let us know if you still need help

1. I checked with a China Mobile SIM and it works. Also, as said before, another China Unicom SIM also works. Only this specific SIM doesn't. It IS unlocked when I purchased it.
2. No way for a warranty - I'm in China and this is a T-Mobile USA device that many local "smartphone gurus" haven't even heard of, let alone "repairing" it.
3. The importer only has one such device in perfect condition (others have plenty of worn and torn), so exchanging is not possible...
I'm thinking of setting up an alternative solution for now...
More update on the issue: even on the China Unicom SIM that got recognized, it wouldn't connect to WCDMA/HSPA+ networks. Did an experiment: I used *#*#4636#*#* to adjust network modes, and when the device is on GSM only / GSM/WCDMA auto / WCDMA preferred, it would receive signal like normal; however, choosing WCDMA only, no signal is received. It seems like the real issue lies within the device after all...

...The Relay isn't a WCDMA device.
Even though the relay is a US tmobile device i would still try to contact samsung. They may be able to help you and it can't hurt. This is certainly not the first Relay to leave the US and incur problems...

What? I mean, my carrier has the HSPA+ 21Mbps/42Mbps it supports... What do you mean by it not supporting WCDMA?

If I understand correctly, the network mode menu option for WCDMA in the CM10 ROM is left over from the D2, which is a phone of similar spec which our developers based our ROM on. It doesn't do anything on the Relay.

But it DOES switch network modes... Or so I think, judging from the symptoms.
The first SIM only supports WCDMA(HSPA+), and when inserted, it can find my carrier's network but can't connect. On the second SIM which is compatible with both GSM/WCDMA, I lose signal only when "WCDMA only" is chosen, and under this situation the symptom is same as above. I assume that it can find my carrier's GSM network but not the WCDMA one.

Bump in vain. I guess I'll be selling this phone if the issue is really within the phone itself...

Sim card reception

Hi,
I have nexus 5 with:
Android ver. 6.0.1
Baseband: M8974A
Build number: MMB29S
I've got a polish sim card ("Play") which works with my Iphone 4s, but when i insert it to my Nexus 5 ....i don't get any reception only emergency only !
Please help
Thank you all
Can the phone see any mobile networks? Could the imei blocked or blacklisted?

I can see mobile networks, but when i choose any one of them it shows:
"Can't connect to the network right now"....the notification is showing no matter which carriers i choose.
Hmm, would the sim card be tied to the iphone's imei? Do you have another sim card to try with the nexus 5? Does the sim card work in another phone (not the iPhone)?
The sim card works fine with the iPhone, as I mentioned earlier, the sim is a Polish sim (pre-paid), when I use it with the iPhone it connects with Vodafone. But when I use it with the nexus 5 6.0.1 OS it cannot register to any carrier.
Try the sim in another phone (not the iPhone) just to see if it can connect. Maybe the sim card is tied to the iPhone's imei.

Help - Unlock Carrier tool

I have a polish sim card which works fine with my other Iphone, when i insert the same sim card to my nexus 5 it can't register to any carrier !
Why is that, is there any solution for this bizarre problem ?
Thanks
You tried the sim with an iphone (works) and Nexus 5 (doesn't work). Did you try the sim in a third phone?
The Nexus 5 cannot be carrier unlocked because it was never carrier locked.
I don't have a third phone. Do you think that I should flash another radio ver. on the phone?
The Nexus 5 detects the sim card? If it does detect the sim card, I think your iphone's imei is somehow tied to the sim card.
What does it mean?
And how can I resolve it?
I would really appreciate any help ?
P.s.
Apparently a different sim (vodaphone) doesn't work in this phone either.
???
Has the vodaphone sim been activated?
If both sim cards do not work in the phone and the phone can see but not connect to networks, it may be possible that the phone is blacklisted? Is the imei correct?

That's friend phone....so....
He said that the sim (which doesn't work right now) worked before. I don't know about the Vodafone sim.
How can i find out that this phone is in the blacklisted?
Thanks again,
You can check the imei here: https://swappa.com/esn
Since the vodaphone sim is not active, it is not a good test of the Nexus 5. It would be best to try an active/working sim in the N5.
1. How can I know if my phone tied to the sim card ? (you mentioned it before)
2. Do you know this website http://www.imei.info/
Thanks
I don't know that site but the swappa site will tell you if the phone is blacklisted.
The only way to tell if the sim card is tied to the iPhone;'s imei is to try the sim in another phone to see if you can connect to the carrier network. In the USA, AT&T tie their prepaid sim cards to a phone imei.
As I mentioned before the sim card worked fine with my iPhone.
But the "fishy" story here is that the Vodafone's sim card doesn't work as well.
So it might be a blacklisted issue.
Your thoughts?
Did you check the imei on the swappa site?
Note yet
I would check the imei to make sure the imei is not blacklisted and does belong to a nexus 5.
I updated my friend to do so.
Thanks

Samsung Z Fold 2 SM-F916U1

Hi all, I have a Z fold 2 Sm-f916u1 and I live in South Africa. Iv been trying to get the sim card to work but no metter the brand of sim I insert the devices does not recognize it. Iv Googled to the best of my ability for a solution but no luck. I know the device carrier is T-mobile. I have tried to contact them with maybe trying to unlock the sim on it but they cannot help me. Samsung un wount help as well as they regard the device as grey stock (not purchased locally). Is their any way with flashing a different version of software or firmware for this device to work with a local sim card. I haven't tried flashing as yet as I want to know for sure that the flashing will work even if its a trial and error situation.
Device Version
AP : F916U1UES1BTK2
CP : F916U1UES1BTK2
CSC : F916U1OYM1BTK2
Does the device give you any error messages when you insert the SIM that you want to use?
Hi no error messages of any sort. After the sim is in it detects it but does not activate a network connection. No 3G or 4G is active not even for calls.

There are more than 10 possible reasons why a mobile device may not be getting signal - it's very hard to know for sure. You should have it examined by an experienced professional in your local area who offers those types of services
