Dual Sim problem

Ok, I have been browsing this forum for a solution to my problem and none seem too specific, at least for my BA wm6.
Here is the problem: I just received a dual sim adapter (the one that needs cutting) -both sims work fine. I can't get them to switch from one sim to the other from my phone. power on/off and flight mode won't do it either. I tried phone alarm, dual sim switcher, and wivit. They don't work for my phone. I also have a wm2003 se BA and tried it on there and I was only to get the dual sim to switch once. So now the dual sim is stuck on SIM2. So it doesn't matter which phone I use I can only use the sim that is on the SIM 2 slot! Blah!!
What I need: A program, or anything to switch my SIMs for my BA wm6. I don't want to keep taking out my sim and open the sim adapter and switch the two sims all the time.
Edit: after fooling around with my 2003se BA I managed to get the Dual Sim Manager to work again, and I noticed that despite switching SIMS, phone information alway display the default SIM. Does this mean that it is not switching? Does this mean that it does switch but the phone does not display it? If latter is the case then I am in big trouble! One SIM has unlimited internet and texting and other one is just a basic plan. Please help! I don't want a surprise bill!
Edit: Sorry, I needed an answer so I'm feverishly testing this crap out. And the answer is yes the sim changes but the phone does not display so. The trick I used is texting my account info and voila! Two different accounts! So, now over to my wm6 BA and check that out

I'm really surprised, that people are so patient to fight with such an uneffective and clumsy device as dual SIM adapter: you have to cut/destroy those SIM cards, then you have to pray that i works with your phone...
I really think, that if you really need to use 2 SIMcards, why not buying a 2nd phone, or just a special phone with 2 radios and for 2 SIMs.
And please don't tell me it's "for comfort" - dualSIM is antiComfort...

There are other solutions that you don't need to cut the sim, one that I have seen is the addapter is placed in the sim slot and the simm are part of the battery pack.
Bottom line is that that one sucks as well.
I feel there is a valid need in my line of work were I would need at least 3 laptops to support the Builds of my customers however VMWare gets me by fine.
As for the phone, I need 2, carry 2 and hate it.
So I would be a buyer if there was anything around worth having. (which as I still have a BA seems not the case).

Dual Sim Problem
Hi pharmeceutikle,
I wonder how this device works for BA at all!
I tried an adapter like yours of a friend of mine and it just doesn't work with my BA.After inserted, I don't see any new menu for it and when I restart the BA, it shows invalid sim message at startup. I have installed a WM6.1 ROM downloaded at this site [20749 (Build 20749.1.4.0 PV DVH) - v13] and my radio version is 1.12 (by the way, it was 1.15 but 1.12 is the only one that worked fine for my device). The same adapter, once installed on a Motorola phone of my friend works pretty fine! so, it's not a problem with the adapter, I guess...
Did you change anything on registry? could you please tell me how did you proceed since cutting the sims until you got it to work, please?
Many thanks!

This dual sim adapter only works if you have a working STK ROMs. I believe I used Helmi's original wm6 as one of them and then I went to others but I can't quite remember which. I posted an experiment with the all the ROMS I used awhile ago so just do a search under my name. Anyways, I couldn't get it to switch sims normally so I had to reset the damn thing all the time. I would go to the STK menu and choose either sim 1 or 2 and then quit out and then reset my phone for it to make the change which really is a pain. As soon as my second sim ran out I just tossed the infernal thing and stuck one sim per phone! Sorry couldn't be much more of a help.

Thanks
Thanks anyway I'll keep searching for a while.

[Q] no network coverage after installing wp7 on my hd2

just installed wp7 on my hd2 and after the start up my phone keeps searching for the network. have tried automatic network selection and tap to select but no luck. am using 2.15 radio. would appreciate any help.

goto your settings, scroll to cellular, then down to add apn, in the apn box type epc.tmobile.com and leave the rest blank.
this works with tmobile us

isn't that supposed to be only for the data connection? even without entering the apn the phone should be able to find the network for just making voice calls. so mine seems to be a different problem. the phone is simply unable to catch any signals.

from my understanding of the whole cell phone fiasco is the sim card has everything the phone needs to connect your providers tower and also tells your phone what services you have voice, data, etc etc, so it should setup voice automatically. i would try searching for the program (htc connection setup) they use to install the xml files it also sets your phone with the provider.
good luck.

Only search at the internet for your apn settings, enter them and voila you can use your data connection, nothing more nothing less and done in a minute. HTC Connection Setup don't work well but you have to use it later if you want to change phone type to HD7 for the Marketplace ^^)

yeah we covered that part, the concern is that the phone is/was not connecting to the towers

Maybe check out other Radio ROM. 2.15 should work well, but uses more battery.

switched back to winmo 6.5 for a while and the same radio worked fine (caught the signal etc.). Just now again tried to flash wp7 using 2 different radios, that is 2.12 and 2.14. Have already tried 2.15 with my first attempt, but the problem just remains the same.... 'no network found'. any thoughts? have even tried putting in the apn too. no luck

u know its funny cus its the exact same with mine exactley the same ive tried everything and it picks up the signals but it wont let me connect to any network at all... the phone is just fine except that one problem.. plz any body help us with this stupid problem

i was havin the same damn problem, and i just flashed the 2.11.50.26 radio, and boom baby!! instant network connection. no more 3 beeps and disconnection for me now to check battery life and wifi (no 3g in trinidad yet, so u can't test that)

sim lock...???
After trying different radios by flashing and re-flashing, I've noticed something I should mention. My phone dialer shows a sim icon with a lock on the top left of the screen. Does that shed a new light on things?

sim lock ???
hey sameer... I have the very same issue with my HTC HD2. It is unlocked and I am facing the very same issue that you are when I revert to WinMo 6.5 everything works fine with the same radio. I've tried almost every radio now and have no luck. However, the funny thing is that I do see the sim with a lock when I go to my dialer. I suspect the OS is SIM Locked, however, when in WinMo 6.5 every Sim Card is recognized and works properly
Any luck with the issue yet??
Let me know of your thoughts... btw I'm on Ufone's Network.

It's the sim card!
Problem solved for me and hopefully for salmanjavaid too!
I learnt it the harder way though, by which I mean that I spent money to buy an HD7 and after inserting my sim in my brand new HD7..... no signal again! oooops! Only then it occurred to me to try some other sim cards. My network is also Ufone here in Pakistan. So first I tried a Prepaid Ufone sim (the one with white and orange colour and 64K printed on the back)...and Lo and Behold my hd7 gets the signal and network settings and data connection works fine too! Other operators' sim cards like Telenor, Warid and Mobilink worked fine too. But when I insert the sim card which is in my use back again....no signals again! This sim card is a different version, perhaps not 64K and plain black color on the back.
A call to my Personal Customer Service Executive assigned by Ufone sets the next course of action. He'll bring a replacement sim card for me, when I get back home.
My suggestion to salmanjavaid: try other sim cards first. If they work then get a replacement sim card.
Hope it solves your problem too.

id give this a shot. I'm on vacations in Pakistan and have my Sim Card from O2. I will give it a shot tonight Thanks for the suggestion.

[q] invalid sim error

Ok so since nobody wishes to answer in direct rom forums, I'm going to ask my question here. I was very successful with Android as that's easy. Installing WP7 was also a breeze and the whole unlock thing cool. Problem is no matter what WP7 rom I try I always have an "Invalid Sim" error emergency call only. I am in canada with my provider being WIND mobile. Am I correct in saying that windmobile sims just dont work with windows mobile? or is anyone else having the same issue or is there a fix for this. All i am asking for is a simple "proper" response without the flaming. I've searched. I'm not new to xda but i am new to wp7. thank you
WOW Ok..

Can you borrow a different carriers SIM (from friends / family / colleagues) to test with, see if that works? That would help to understand if it is your SIM or the install of WP7. TBH it does sound like it is the SIM that is at issue.
edit: I just checked and the HTC connection setup app (from the market) does list both Canada and WIND, try it

Hey first of all thanks for a response. I'm also thinking it's not the sim (i'll try my wife's rogers sim card when she gets in from work.) because it works perfect with winmo 6.5 and Android without issue. I tried 3 WP7 roms and none worked with the sim..which boggles me
OK so after using my wife's rogers sim card it worked perfectly so it IS the wind mobile card that is not compatible with wp7. I guess i need to find a way to make it compatible if there is one.

I've gotten sim errors on my real hd7. To fix it, I have pulled the battery and reseated the sim. You might try to get a new sim from your carrier, just tell them your old one is acting up.

Tried that a few times and figure it may just be my SIM period although it's strange that it works without error with the android roms. But yeah imma go into Wind and grab a replacement and see how that goes

Did a new SIM help you, or did you do anything else?
After I have entered my PIN my sim is working fine, but after some time it says Invalid SIM.
/Regards Lars

I think it's an issue with the Roms. I think there are a lot of people getting the invalid sim error. I use the BlackSideSeven rom and I've seen several posts about it in the thread. There are also several other threads started about possible fixes and stuff.
Here's a link.
The easiest way to resolve is to turn on airplane mode and then switch it off. It doesn't stop it from happening, but at least you don't need to reboot.

Error in Android as well
I am having the same problem with MDJ Froyo 2.2. When I reboot into winmo 6.5 great signal all fine. I did notice that the simm card did move in the slot possibly bad connection. Now that I reseated the Simm all is fine. I also just read about antenna issue with the HD2 going to open and fix it to see if that helps.

hd2 t mobile unlock problems

hello friends, ask you about a strange problem.
i've bought a hd2 t mobile from USA ebayer, unlocked and with WINDOWS PHONE 7. I put my Italian SIM (vodafone italy) and notice that i can't use it. call seller and he wrote me unlock code. don't remember if after this i have tried to call, or if have seen the signal strenght, but i have changed to android. the seller used magldr 1.10, but i experienced that with this version the system had restart and restant such as looping mode. so i've found magldr 1.13, and this one permits to android to start.
Now everything runs well, except i can't call. the phone runs, because i can do emergency calls, and with another SIM, 3G italy, an UMTS provider, in some places i can use it normally. but is very poor signal, the most is absent. when i put inside Vodafone SIM i have no signal at all. Close to this i have italian LEgend HTC with Another Vodafone SIM and Full signal. if i ask to find network, even with vodafone, he finds only 3G.
If this problem come from bad unlocking, s there something to do to solve it? i though to try to unlock it againm but now it doesn't ask me for code. so what to do? lock it and unlock again? is possible?
another problem: with phone there is a 16 gb Sd card. i see only 200 mb, before i thought was damaged, but trying to reinstall wP7, i have read on a site that is WP7 that format 200 mb for working. now, how can i do to take back the entire 16 gb of space?

If I were you I'd flash back to the Stock TMOUS ROM and make sure the phone is mechanically sound before doing any more software installs. If the phone doesn't work from a stock ROM, then the device is defective. You have too many variables that could be causing the problems. Get back to stock and then add one thing at a time to your device.
EDIT: An unlock code should work regardless of what you do with the phone, so I don't think that is the issue.

Ok first off what radio version do you have on the HD2 as this might be your reception problem. Certain radio versions work better in certain areas but the latest version 2.15.50.14 seems to work well for everyone. TO flash a different radio version to your HD2 go to "[RADIO] The HTC HD2 Master Radio Thread" and download the radio version you want to use, you may want to try several different ones until you find one that works for you. If you have the international HD2 with 512MB ram you can flash any radio version. If you have the TMOUS HD2 you can only flash radio versions2.06.50.xx and up, do not flash a 2.04.50.xx, 2.05.50.xx, or any x.xx.51.xx tradio version to a TMOUS as it will brick the phone. If you have all whit external buttons at the bottom of the HD2 you have a international model, if you have a green send button and a red end button it is a TMOUS. Put your HD2 into the multicolor bootloader screen by holding the volume down button down while powering on, connect your HD2 via USB and wait for the Serial in the white bar of bootloader to change to USB then flash the radio.
To get your full 16GB back on your memory card you will have to reformat it cause WP7 puts a funky format on the SD card as it uses the SD card as the internal memory. The easiest way to do this is to get a SD card adapter and put your SD card in it then stick it in a digital camera and format it with the camera then format it with your computer using fat 32, this will give you your full 16GBs back.

thank you both for help. i have already tried to go back to original rom and windows 6.5 for Tmous. no way. but it can call, emergency call runs and with a 3G SIM i can call. the seller said he unlocked hd2 in USA before sending me, i had to unlock it again wit my sim. so there is something strange. seems it has a low signal power, and refuse GSM signal. tomorrw i will take it in a lab for testing of signal. then i will wite here again.

Are you saying you could not flash it back to stock, or that after the flash it appears to be still locked?

i flashed back, removed Hspl, putting a rom on SD and renaming leoimg.***.
then i have installed an original win 6.5 rom.
the same i've done today again, only with a rom for win 6,5.
notice: in win 6,5 the IMEI was longer, finished with a 01 more than other view from android doing *#06#- may be is not important.
the only way to see a carrier working is to put 3G sim and the correct APN.

Ok someone correct me if I am wrong please as I am going on what I consider to be basic knowledge of both subjects here. But the APN settings are basically just for your data/internet connection to work properly with the carrier you have as you have to access their servers to go online.The radio is what is in control of voice communication along with the phone hardware. The hardware also has control over the data connection to but it is more to the extent if you can use 2G, 3G, or 4G. So in summary if you are having voice problems change your radio version, if you are having data connection trouble check your APN settings.

hardware
thank yo for your help.
i have took back the phone from LAB.
no way, there is a hardware damage, due, may be, to transport from USA to Italy. the involved side is in reception, the chip is damaged due to accidental shock, and has a very low activity. only where the signal is full, the damaged filter let it work, but it's always a strange way to do it, totally full signal and no signal in a few seconds. T.Mobile is not supported by european HTC, so i must send back the phone in USA

Cant recieve calls sometimes

Hello
My HD2 does have full signal, but sometimes when people call me they get a phone is not available reply. I have tested this with a different radios, roms even on android and wp7. I've even tried switching to 3g even though im on a prepaid card. Please help!

You have a faulty SIM card, I would try getting another SIM card. If this does not help you may have issues with the SIM card tray in your device. If you have full signal then you do not have a reception or antennae issue and what I have mentioned is really the only next logical reason for your issue. ssIM cards just like anything else go bad from time to time even if they are not that old.

He's right, this is what I suspect too: a faulty SIM card.
Even it looks a bit odd, faulty SIM cards can be (more often than expected, and I mean it!) a p.i.t.a.
As a side note: I encountered a SIM card that was working perfectly with some common phones (nokia, zte or whatever), but not working at all with a Samy Exhibit 4g until SIM card replaced!

Currently I flashed the 2.12 radio and it seems to accept calls better sometimes but I still recieve the call error less frequently now.

Well seeing as you have tried different SIM cards then it very well may be a issue with your SIM card tray then. But I do suggest you flash the 2.15.50.14 radio and see if that helps, but I have a feeling you were already using it before you flashed the 2.12 radio.
