SIM Cards on Samsung I780 - Upgrading, Modifying and Unlocking

Folks,
I have a Samsung i780 with a dual sim installed. each time I switch the SIM card by SW, all my mail accounts disapears. The switching by SW only does a reboot to phone module (not do device), but appears a message stating "SIM card changed, phone will be reinitialized) and then the mail account disapears.
Any clue on why this happens ? I believe there is a proprietary Samsung service running on WM6 that produces this behavior.
Any help will be appreciated.
Best Regards to all

How did you get 2 sim cards on the i780? what did you use to achieve that?

Dual sim/software switching??

Ok - some mobiles had option I believe(unconfirmed) that with 2 sim cards installed, a piece of software on the phone allowed switching between sim cards - saves turning them on/off - any idea if the xda has this option?
Reason being - I have a personal sim card, and now I have a work one BUT would prfer just one phne and do prefer the xda
Scott
yep
I use "wivit" sim switcher, works just fine on my xda2s, xda2 and xda2i

wivit
Wivit doesnt works on WM05
I know this is a longshot - but anyone know with this type of software if the software will tell you that a call is coming in on say on 1 sim card, so that you can then switch to that sim card???
Cheers
Scott
Very long shot - It doesn't work. Only one SIM at a time is connected. What I do is set up a divert from one to the other, so that I can always received all my calls whichever SIM is active & then simply switch to the appropriate SIM when making calls

dual SIM

Hi
is possible have work at same time two SIM's for exemple TMN and Vodafone if I buy a new card and copy this two data for one SIM card?
or I need change when restart the phone?

tricky question in theory yes you can do it, I had 2 sim cards cloned on one special SIM (up to 6 numbers) working on p3600 during a long time, but these were from TMN (SIM compV1). Vodafone in portugal is using since 2002 SIM compV2 and these cannot be cloned (clonning uses a brutal force atack to get internal codes from original SIM) and the compV2 has a "defense" mechanism that may crack the SIM during the scanning.
if you can achieve this, the SIM change is done by Software only, so there is only the need to restart phone module of the PDA (5 seconds to do it).
Another alternative is to use a system of DUAL SIM also, but this requires that you cut the SIM chip of each card and uses a special card to insert the 2 chips (for the p3600 I saw it working with a maximum of 2 chips)
e é tudo and that's all folks

Locked SIM card

Hello guys!
I have a phablet Cube WP 10 with a locked SIM card (No service status). I already installed InteropTools_2.0.95.0 and searched in the registry of OS using the Interop Registry browser, but couldn't find any parameter related with a the SIM card and its status.
What should I do to unlock the SIM? May be there is another trick without using the registry?
Attention! Added information: The SIM card works with another phone and this phone sees it, but can't use the cell network - "No service" when calling...
Which carrier is the sim card from? What do you mean sim card lock? SIM card has a pin enabled?
Try putting the sime card into another phone yet?
You won't unlock locked phone to use SIM from another carrier by modifying registry. There is no such a thing.

No service
The SIM card works and the phone sees it, but can't use the cell network - "No service" when calling...
If you purchased your cube for a specific operator, you must call this operator to have the unlock code.

I thought the Cube WP was an unlocked device.
If the SIM sees no network that means the sim is not compatible. I am not sure what the problem is exactly.
I've changed current SIM card to the SIM card of another cell-operator, but nothing has changed. And what is important to mention, I can't find any cell-network of my region using the network search. May be it's some kind of lock?

maybe, simply the phablet has a hardware issue - most probably antenna has been disconnected from the motherboard
I have sim cards that if they are deactivated will get no service when inserted into a valid phone they can work on. Are you using an active sim? If so maybe look at this link as there are some service codes to try maybe...but make sure to read any warnings. Not sure if any of them work either.

Both these sim cards are active because they works with other phones.
Thanks for this link, but these codes destined for Android OS and don't work on WM10 except first one.
Wad worth a shot anyway.

[QUESTION] Xiaomi Redmi Note 8T GPS

Hello everyone,
I recently bought a Xiaomi redmi note 8T.
I bought it in belgium. I live in belgium. I have a belgian SIM card, and everything works fine.
Context :
I have put my second SIM car in it, which is a french SIM card.
This second SIM CARD is then using Roaming data. Which i allowed.
I want to use this one as i have more data on my plan than with the belgian one.
Problem :
I have limited access to internet.
I can send and receive messages on what'sapp & messenger for instance.
I can also find where i am on Maps & Waze
BUT i can't find a destination, nor calculate an itinary.
I can't use google or opera.
I found the option to setup to use one or the other SIM card for "Internet".
I also tried to connect to ALL belgian mobile networks with my french SIM card, all the same results.
I have added the speed so i can see i go above 10KB/s (and more when updating apps) with my belgian SIM card.
With my french SIM card, never above 2KB/s.
I deduce i have some limited access to the internet with my roaming french sim card.
However, i used to havemy french sim card on my HTC U11 (before it broke down / same configuration, using both SIM cards) working jsut perfectly fine.
Therefore i don't think it is from the belgian networks operators.
So i suppose i have this limit setup by Xiaomi... correct ?
Anyone has any idea how to fix this please ?
Many thanks for your time and your help !
