Hi,
It seems weird.
Did you drop it or changed anything?
If you have accidently changed few things while playing with any system's tweak app,
Try doing a factory reset. And if you are using BMM, try installing other ROMs available...

If other sim cards work then it would seem that you may have a bad, or possibly damaged, sim. Try to get your carrier to replace it for you.

I used different sim of same network but problem still persist. Only problem with airtel network. Sim of all other network works fine.

If the only problem is with the airtel network sim card(s) then it must be a network issue. I would say at this point you should contact Airtel and be sure that your phone is compatible with their network. They might even be able to offer you a solution like maybe a different sim card, and/or a different service plan that your phone will be able to function on. Either way, it sounds like a network issue rather than a phone issue and should be resolved by Airtel. Sorry I can't be more helpful than that. Maybe someone here that is on the same network knows of a workaround.

I just had to say this... Not being a jerk, but more of a smart arse...
Maybe if you were using airtel instead of suing them it would work.
All kidding aside.
The a2 is known to have issues with some telco's sims, just politely tell them you require a new 64k sim card, and see if that helps. It seems many have had issues with the airtel India sim cards even if they once worked in the phone, and just stopped.

Thanx buddy
I already tried many other sims of airtel of my friends but the problem is same. Sometimes phone got the signal for 3 to 4 hrs with airtel sim. After that signals accidently lost.

Do you have the 64k sim card as jimbridgman suggested? If not then try that.
If you do have a 64k sim and it still isn't working then the only thing left that I can think of is hardware failure.

[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...

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.

[Q] Moto G Connection Problems

Anyone else facing the same issue as me in Moto G? For me If I am using 2 sim cards at the same time, the connection frquently drops. It will show no network for 10-15 seconds for both sim cards and then come on again. When the network goes, it shows that the Flight Mode is activated.
Version : 4.4.2
Build :171.44.31.falcon_umtsds.AsiaRetail.en.03

You're not the only one. Many people including myself have reported this problem to motorola. They have said that the techs are working hard on fixing the issues with connectivity but it will take a few weeks to a few months before a fix is sent out. All we can do is wait.

It's been had to say in my case because my area doesn't have good signal anyway, but I have had more problems than my previous phone here. If the phone hasn't been used for a while I find it's lost connectivity...

Sim Free vs Branded Moto G - 3G Signal loss!

Hi,
I have a Vodaphone branded UK Moto G - I have just unlocked it successfully and flashed the stock FW. My friend has a Sim free Moto G. I was concerned because on my Moto G I cannot get 3G signal in the house, all I get is "G" rather than "3G/H+"
Using the same sim in my friends Sim Free Moto G, I can get H+ very eassily in the same house when the phone are placed still on a desk.
Does anyone know why this might be? I'd like to know if it's worth me getting mine replaced first before taking it back and paying the extra for a sim free model?
thanks

Are both devices on the same modem version?

They both seem to be identical in software (in the about phone section)
And the only visible difference is the back of the branded
One has a white M rather than black.

I don't know if this will solve your issue but download phone testing from diewland from playstore and set your network to "WCDMA ONLY" and see if it helps. If not it might need to reconfigure your apn.

You can check/select the network type by going to the dialer and dialing *#*#4636#*#* and looking in the phone information section

Z3 Dual D6633 SIM compatibility / issues

Hi, I've got a Z3 dual D6633 which I want to use with an EE SIM in the UK. I've tried a cut down microsim and been into the EE shop and tried one of their nano SIMs but both don't work correctly in the phone.
The cut down SIM makes a service phone.android.com or something like that continually crash and doesn't connect to the network.
The one I tried in the shop just doesn't connect to the network.
This is on 23.0.F.1.74 and .82 I noticed in the release notes for .82a fix for Yoga SIMs in Russia but don't know what the problem there was, but wonder if it is linked. All other UK Sims work including 3, Lyca, giffgaff, Vodafone, virgin just not EE. has anyone got an EE one working or had similar problems?
I did notice that an app/widget I use called phono to show network info and signal strength usually shows the IMEI when no SIM inserted or the MSISDN, however with the non-working EE SIM it just shows 00000 - not sure which field it is getting wrong. Oh and yes the SIMs work fine in all other phones I've tried.
I do need to try more tests on factory reset and removing phono etc but so far it looks to be a firmware incompatibility with EE Sims.

OK, so I did a few more tests and got hold of another nano SIM on EE.
So it looks like the 23.0.F.1.74 firmware does not like EE SIMs and the phone application constantly crashes. On the later .82 firmware it works fine. I was mislead a bit by going into an EE store and trying a SIM - they must have given me an un-provisioned SIM to try. I stupidly assumed they would have actually given me a SIM that worked, doh!

I'm experiencing something similar here. I have the D6633, bought in UK, now I am in Brazil and the phone works great except that it won't connect to the 4G/3G/2G/LTE network. I can make calls, send sms normal. But internet only over wi-fi.
I called my operator, they say the phone is configured correctly, I tried my brother's sim card from another operator and the same happens.
So, the phone is clearly unlocked, if not it wouldn't recognize the sim cards at all. But no connection to the internet...
Any suggestions? I already did four factory resets, I recovered the Rom using sony software...

Same issue

Hello, I have the exact same problem. How did you get the firmware .82/for what country? Is everything working well with it? Really appreciate your guidance.

I had the same problem with the EE sim card, ended up sending the phone back.

I purchased my D6633 from Saudi Arabia and the 23.0.F.1.82 update came as an OTA notification about a week ago.
If you look in this thread http://forum.xda-developers.com/z3/general/d6633-z3-dual-updated-to-23-0-f-1-82-t2929352/ it mentions that someone thinks the update has only been released for Saudi and Brazil - I assume it is for Europe as well as one of the release notes says a problem with Russian Yota SIMs has been fixed. I think there are also links to the firmware in there although I've not looked that hard as I got the OTA. I guess it might still in my memory - anyone know where Sony stick their OTAs?
Seems to work fine so far - no noticeable difference - well other than EE SIMs now work!

Hmmm, sounds like another issue as with mine the EE SIM caused the phone.apk to constantly crash/restart.
Did the data work OK in the UK?
As you can make calls/SMS I assume you are at least on a 2G network which should still give you (very slooow) data - It does sound more like an APN issue - or something else. I know you said you checked with your operator what their APN settings should be (just my experience with operator customer support lines) - but I would try and have a look yourself - and maybe list your APN settings and operator and someone may spot something.
I have seen a couple of phones / operators where the "APN type" in the APN settings needs specific settings - its down the bottom and often isn't mentioned when people get the settings. For example in my current settings I have "default,hipri,dun,supl" for Virgin mobile in the UK.

For mine, on my networks here in Australia, I can assign 4G LTE to any sim, however, that makes the other sim 2G only (GSM).
The other option is to have both at 3G (WCDMA/HSPA).

If you assign 4g to sim one that work only for 4g or like other phones "LTE(preference)/WCDMA/GSM"
4g not available automatically search 3G if 3G not available automatically search 2G?
Assume second sim is on 2g

Yes, your 4G sim slot will fall back onto 3G and 2G as per expected for most handsets.

I just got a 6633 through kogan and i am having real trouble getting it to connect to optus network with iinet and truphone simcards. Does anyone know if i need to update any settings or firmware from factory to make it compatible. I can see iinet and truphone lte networks (which i assume is the optus 4g network) when searching manually but the phone wont connect. Sims work in a mates iphone6 without a problem.

Don't suppose anyone knows how to get rid of the #sim card icon on the statusbar?

Have you managed to root it? I rooted the 23.0.1.f.0.96 firmware for my Z3 D6633, but after a while (half a day) it starts to reboot frequently, and Google Play stops working (can browse apps, but not download them, as the download bar never progresses).
Also, my EE sim seems to work, but the phone still shows it as 'Sim 1 0000000' whereas other sims simply appear as sim 1 and sim 2.
I am wondering if I should just downgrade back to 23.0.F.1.74 and move from EE to Vodafone or 3...

Ah, work forced a BlackBerry (yuck!) on me and I've since sold the D6633.
