Dual Sim Problem

Hey guys,
I got an analogue dual sim adapter. When I start the phone with the first sim card it's ok. But as soon as I wanna switch to SIM2, it tells me, the sim card was missing. When I do a reboot instead of turning off and on the telephone module, it works. The strange is, when I do a switch from SIM2 to SIM1, there is no problem at all. Neither by restart nor by turning telefunction off and on.
I already tried to switch the sim cards manually in the adapter. No change. Always the problem by switching from SIM1 to 2.
Does anybody have a solution?
Btw. I run WM6 Touch VII. But it's the same problem with WM5.

Dual Sim
I assume that your sim is Analog? I'm not sure exactly how those work, but I had a similar problem with my Digital dual sim. It would always give a sim blocked message while trying to switch in the one direction. In the other direction it was fine. It turned out that my provider required the exact Telephone number to be the name of the Sim. When I changed the name, everything worked fine. Since it sounds like you have an analog model, I'm not sure if you can change the name, but if you can, it's worth a try.
P.S. The Digital Dual Sim really burn a lot of Battery, so I can't really recommend it.

yes. as i wrote it is analog. i can't change the names of the sim card.

Analog Sim Adapter
Which Radio Rom are you using? I would recommend 2.69.21. Since it works on a softreset and not with the Phone on off switch in ConnectionsManager, I would guess that you Radio Rom is not compatible with your SIM. Try flashing a new Radio ROM to see if that helps, if not, you can always another. If none of the radio roms work... well, try bringing back the SIM and getting a new one or something.

i updated to the newest radio rom version. And nothing changed. still "sim card missing". I suppose there's something wrong with my simcard.

Probably, but I did think of one other thing. It's kinda dumb, but maybe worth checking out: Is possibly one SIM slightly thicker than the other? If so that might be the problem. You could then try wedging paper in between to give it better contact. Otherwise, good luck with bringing it back, or exchanging it.
P.S. Have you tried it in a different Cell phone?

yes, i tried in a different one. there it works... strange.
thanks for your help anyways.

Have you tried all the radio roms? In your situation, I would flash every radio rom on the ftp just to try it out. Maybe the oldest one will help, maybe 2.47.21? Who knows? But if the card works in a different phone, then I can't see why it wouldn't work in the Prophet??? I have a Digital Dual Sim, and that works fine, but drains the battery

Hmm, interesting, I have a simmilar problem on my wizard. But it happens only with one particular pair of cards, other works flawleslly.
On my device it doesnt show the message, it even looks like it logs to the network correctly, but its imposible to make call, access Sim card or any phone options. It looks like the phone module hanged, and only solution is a soft-reset.
I didnt even thinked that the SIM card names have anything todo with that. Can you tell me in what format you put the number? I mean, did you put the country code in front of it (like eg. 44 or +44).
I have already tried to put the number, but still no success.
Also I have looked through many ROM's (more than 10) and tried almost all available radio's and always the same, no success.
PS About battery drain, i own a 15gen. dual sim card and it have exactly same power consumption as used without it. So seek for a new DualSim, they dont have increased drain.

[Q] [help please] Your sim card does not allow connection...

Hi guys,
ok... I have an HTC desire... originally on Virgin Mobile and now unlocked. I'm an O2 customer...
I have rooted and installed the Leedroid rom... originally at version 1.8b. Everything was fine.... until I had a corruption on the SD card.... which I fixed when I got a second following a couple of days of "mounted read only." A day or so later, I lost connection to the O2 network and have been unable to regain it, despite several ROM (I'm now running Leedroid 1.9) and radio reflashes.
I still have access to wi-fi, gps etc.
I have tested my sim card in another phone (all ok) as well as other sim cards in my phone (doesn't work.) I have also swapped and tried another O2 sim.
The phone detects all the major networks... just won't let me connect.
The error message I get when trying to connect to a network manually is "your sim card does not allow a connection to this network"
I've obviously checked that the phone isn't IMEI blocked etc. I've also tried the sim unlock from the fastboot menu, the switching on and off of the radio, airplane mode... lots and lots of stuff.
I really am at my wits end with this issue. I love the desire... but it's obviously of no use to me without the phone element!!!
Can anyone please suggest something to solve this problem???? Could the corruption of the sd card have caused this in some way, despite several rom/radio reflashes since? I really want to stick with the desire, but at the moment I effectively have a £400 brick....
Thanks in advance for any help you might be able to provide.....

Firstly this is not a development issue, its a question.....
But anyway, when the phone is telling you that you cannot connect to the network is it allowing you to enter an unlock code at all? Or have you ever "unlocked" the phone in the past?

You're right Lenny... apologies for creating the thread in the wrong part of the forum.... perhaps a mod could move it....
Yes... the phone was unlocked from Virgin mobile prior to me buying it [from ebay.] I didn't perceive this to be an issue, given that I actually had connection to O2 for a day or two before losing it...
No... the phone/sim is not asking for a code when I attempt to connect.
Thanks,
Shep

and did it stop letting you on randomly, or did you do something immediately before?

Nope... completely random. I was in a poor reception area and initially put it down to this... but then it never returned and I'm now back at home having had zero connection for a week.
I think that my repair of the SD card was after I initially lost connection. But as I said, I'm not sure whether the SD card corruption is a red herring.

Call me sceptical, but I doubt you would of been able to check whether it was on the IMEI blacklist or not unless you worked for a phone network.
It's not public knowledge and someone working for O2 shouldn't have told you if it was or wasn't.
Also, even if they did and the IMEI listed on the handset is NOT blacklisted, as was possible with WinMo devices, you may have unintentionally changed the recorded IMEI on the handset to one that IS blacklisted - unlikely though I'll admit.

the sd card should not have anything to do with radio.
Go to dialer and dial *#*#4636#*#*
then press phone info

done.... what info do i need to post?

try to go down the bottom and press the "turn radio off" button
then when its turned off try to turn it back on, then see what happens.

Just done it and no changes.
Did it several times between reflashes too... not so much as a flicker...

No idea then, unless the IMEI has been blacklisted.

Ok.... thanks anyway.

Any luck getting this to work? Am in the same situation - t-Mobile unlocked Desire with a 3 SIM?
Edit: I have intermittent reception/connection to 3 now - I did a lot of recovering/trying RUUs which would partially load on Win 7 then just disappear...assume they should have done something more than that. What seems to have helped - and I partially had this problem in my Nokia E65 - was to place a piece of paper (SIM sized) behind the SIM to 'push' it onto the contacts. Well, maybe it was a software issus but it's now my luck paper and I'm not removing it!

Gone again. Very annoying.
RUU'd to RUU_Bravo_Froyo_HTC_WWE_2.29.405.5_Radio_32.49.00.32U_5.11.05.27_release_159811_signed (unbranded 2.2) and still no luck.
Any ideas?

Proud New owner. Need help with data/APN

Hello everyone!
i just got my HTC One X last night.
This morning i got a new sim from T-Mobile and popped it in.
Everything was well except for the data. When I go to access point name menu it says sim card not detected but i can make calls and text.
I don't know what's wrong. I'm am running NRGZ rom if that helps. Yet to try it with the stock rom. I'm running it on the T-Mobile US network.
I tried rebooting and re flashing, but it still isn't detecting the sim card in the access point names menu.
I have no idea what to do.
Whenever i enter the T-Mobile APN settings, it does not save. it says APN Saved, but it does not show up in the list.
Thanks in advance for any help

So i was browsing through the Q and A here
and i found this link

does this apply to me?

Exact same issue here!

I have been experiencing the exact same issue.
Yesterday I went to T-Mobile store and picked up a micro-SIM. Tried programming the APN by hand but had the same results as you described.
When I interacted with T-Mobile support last night, they tried to send in a message that supposedly would auto-configure the phone, but the message never arrived.
I got in touch with the ebay reseller, who suggested that the phone does not work on 1700MHz network provided by T-Mobile. I think it's not exact that, it has to do with the SIM itself.
I will pester T-Mobile store clerk tomorrow and post you results.

Guys, you have to fully read these threads. This issue has been discussed over several threads now.
The current micro SIM cards provided by T Mobile do not play nice with our One X. You have to search the retail stores for a non GBA micro SIM. The non GBA micro SIM cards allow for voice and data and your One X will auto configure.
The newer micro SIMs from T Mobile will only allow for voice. I don't exactly know why that is but that's what it is. Don't bother calling customer care as they cannot order the older/non GBA micro SIM for you. You have to call the physical stores and ask.
Also, you will currently only get 2g data until T Mobile USA switches 3g data to the 1900 MHz band in your area.
Good luck with your search!

Dude, you quoted a thread that I started, and you posted on that thread and I gave you a reply there and now here.
Take the time to read the post. Some of us may be going through what you are going through and are willing to share advice and experiences that may help you but you have to read the post/reply's.
Good luck with your One X.

[Q] Disconnected because service is unavailable

Hoping someone can provide some direction. First and foremost I am not a HTC savvy so although there are a few threads here about the same issue none of them relate to me as I have not rooted the phone nor flashed to custom ROMs or anything to that nature. I am simple user of the phone... Now.. to the topic.. so I bought this phone for my brother in law last year as a birthday present, and at the time I had a working phone so I didnt put my mind too much to it.. but I did liked the phone very much. Two months ago, I decided to purchase one of these, so I bougtht an HTC ONE X Phone S720e Android 32GB 8MP 3G WiFi GPS Bluetooth Unlocked White. I don´t recall what versión of Android it carried at the time but looking at the specs it should had come with Android 4.0.3. After loading it up, transfering my files on to it and loading some basic apps, whatsapp, email, Skype... it off coursed asked for a software update two times which I went ahead and did. The last one it installed added Android 4.2.2 and HTC Sense 5. It was working fine, layout changed considerably... now after doing another of the updates to applications and software, specifically the transfer files update it suddenly quit recognizing data services completely. I though it might be something with the micro sim, so I tried testing a couple of others, it didnt make a difference so I decided to back up my contacts and information I had on the phone and did a Factory reset. It wipped it clean but issue remains the sames, it is unable to even recognize the sim card is missing and when I go into settings I see the message Disconnected because service is unavailable.
Reading online, saw a few folks stating that this situation was related to software updates.. so I was wondering if I could get some help on how to get this fixed. Not sure what to do, downgrade to 4.0.3 or how could I get it resolved so appreciate some direction here.

If you go to settings - about - phone identity, does it still shows the imei ? Seen many people here having their imei gone from their phone and becomes an iPod since we can't write it back. Tho you are on stock, so better send it for repair.

It shows up as unknown actually... is this a software related issue then? Im concerned about the other phone going through the same situation... should no updates be installed to it then? That makes it fairly useless and might prefer to send it back and try to get a refund instead.

same problem for me, still wait for fix

Should I upgrade my Sim Card?

I have been reading some really scary things regarding Sim Cards and viruses or malware or whatever and am wondering if I should change my sim card. A part of me thinks that the idea of a Sim card being infected is silly, but at the same time, I really would not know, lol.
If I were to upgrade my sim card...
Would it put my unlimited data at risk? (Verizon)
How would I go about changing my Sim? Could I use the sim that came with my note 4?
Also, should anyone even worry about their sim cards? o .0

SIM cards are free at corporate stores and you will not lose your unlimited.
Just take your phone in and ask for a new SIM. If they ask why tell them you've been getting errors or something. It takes like 5 minutes if there's no wait.
I don't think you can do a SIM swap online but you probably can by calling customer service from a different phone
Edit: If you call CS for a SIM swap make sure you have your other SIM on hand for the ICCID

Ah.. I see!
I actually tried to do a sim swap at home because google made it seem simple; however, it never worked to my knowledge. At first, I popped in the sim and it said that it was setting up, but never finished. While my phone was trying to activate with the new sim card, I went to the verizon wireless website and tried to activate my phone there, but could not find my phone listed in the section with previously activated phones. I did not try the option to activate a phone that wasn't registered already and just backed out. I did not - to my knowledge - see any screen indicating plan changes so I'm assuming that I did not do anything that could compromise my plan(?). When I dialed the number for activating sim cards, it went to the visual *611 screen and claimed that it did not recognize my number and asked me to log in to my verizon account. After doing so, nothing seemed to happen and it just sent me back to my home screen.
In hindsight, I probably should have stopped after it asked me to log in to my verizon account, but I suppose now all I can do is wait and ask questions to ease my anxiety x_x

You have to call that number from a different phone. Your phone doesn't hold your phone number so just popping a new SIM won't do anything.
You could try to do the "activate device" thing online but I don't know if there's an option to use a different SIM.
